Auto news on Youtube Mar 30 2018

Hi, I'm Maureen Francisco, and my character's name is Heather.

So, I saw an ad posted online, and I'm someone who is terrified of horror films.

So I thought, you know what? This is my time to overcome my fears.

And I thought, you know what? Why not be in a film?

And I had no idea that I would be one of the lead characters.

I loved playing Heather because she has no filter.

And I love not being able to think before I speak and just be blunt.

And, with me sometimes,

I do think before I speak because you always want to be polite,

I was raised properly, but with Heather anything goes, and I love that.

So, the love triangle between Dean and Lacy,

I thought was well orchestrated, is because during the film, I started to really despise Lacy.

And Lacy is played by Melissa.

She's a good friend of mine.

So, on set, I forgot that we had this friendship,

and towards the end of the filming,

I really came to resent her. I really, really did.

But, we are good friends, so years have gone by.

But I thought the love triangle was played well

Earlier today, we found a cave outside the Cascade Ski Lodge.

My favorite part is probably all the blood,

the actual killings, because I, once again,

am afraid of horror films,

and to actually watch it, and be in the moment and feel the fear,

And know this is all make-believe. I love that. I love scaring myself to death during the process.

Dark Souls 2: Demon of Song - Duration: 7:01.

Fighting through all aggressive servants of the Shrine of Amana,

we finally come to the Demon,

who was kept in detention here.

He was imprisoned for the fact that he ate people, and at first

he lured them with his charming voice and songs -

made himself a playlist hits of Kirkorov and some poor people

went to listen to him.

There is nothing more about him,

but for his abilities he was called the Demon of Song.

And now he broke free

and continues his chants

hoping to dine someone.

You can call two phantoms on this boss -

Hunter Schmidt in the second hut, after the ogre,

and Felicia the Brave - near the third bonfire.

That's the Demon will be pleased just three carcasses :-)

Looking ahead, I will say that Demon of Songs - this is a giant frog

and he sits there in the water,

so this boss has big resistance to fire.

But to all the rest types of damage, resistance are very low.

Well, go into the fog, look at this singer.

As I said - a giant frog, in whose mouth

creepy face - sits, singing an angelic voice, lures music lovers

When we approaching, appear bony hands

and cover the frog costume.

I do not know what it's made of,

but pierce the frog skin will not work.

But the skull and hands of the demon are very vulnerable.

Therefore, we follow such tactics - we stand at a small distance

and wait until he gets out of his armor,

let's go so that we do not get punches

and after two misses boss stops

and we can approach to beat in the answer.

Sometimes he will jump away back - we just need

again come closer and wait when he gets out

from his own skin.

With a distant attack, you need not even to wait when he waves his hands -

depart for the radius of defeat and start shooting.

Boss of course does not appreciate our impudence and will begin

jump and in every way reduce the distance.

Well, with magic comes very good damage.

Therefore, the battle can be very fast,

but let's see what else he can do.

That's how he spreads his arms out and makes hugs - very

dangerous attack if you get caught. I'll try again.

Boss protrudes and does not exactly what is needed.

We are waiting for two blows, we throw our two and repeat.

This is a new attack - the boss straightens up

and spanked from all height, stretching the entire length of the arena.

So, what now...

Here they are - hugs.

Suffices for the hands and slam, slam on the ground three times -

nice that I had almost complete band of health.

In general, this is not the type, with which you can so fraternize.

And the boss in the meantime typed distance and preparing to throw out

one more action - something there puffs up, rests

and makes a powerful jerk.

Well, of course, given its dimensions,

completely dodge is quite difficult,

but it's good that this attack does not do much damage.

And then he repeats again: jumping, head, hands and so on.

Interestingly, this frog there is a tail, when it rises

very clearly seen hefty tail.

Unfortunately chop it off is impossible, but if someone wants

to try, then the boss can carry out a tail attack,

but this is an extremely rare phenomenon - usually he just turns his head to us.

So we forget the tail, and return to the main limbs.

In principle, this is almost all of his attacks,

he also knows how to shoot bursts of water balloons -

this he does in those who far away.

Therefore, run from him it's not necessary, it's enough to stand

in the right place.

The main thing - to understand in time what is happening,

jump back and slightly to the side.

Well, if we dodged well, then conduct a counterattack.

At this end the story Demon of Song -

sitting, sitting in the lock, broke out, walked, had dinner and enough.

In general, I do not understand the meaning jail one, who

will outlive many times and those who planted him and the jailers.

Well, at least he was appointed some corrective work -

let it benefit society.

Well, don`t know... would clean the sewer, would dig up the fields.

And so that's it, the demon died.

Victory.

We get the Soul of the demon and the Key to the Embedded.

Well, as usual, the soul is exchanged on the weapon - Spotted Whip.

Very poisonous whip.

And the Key to the Embedded not just a key, it's both

a big sword, and very light of big swords,

with good damage.

But he looks really as a great key,

and they really can open chains Embedded in the Drangleic Castle,

and release the Milfanito.

This one Embedded when infected the curse of zombies,

understood that his case was bad, started himself in a chain and began to wait,

while someone comes and pierce him by key.

Why did he lock up the Milfanito, and how the key came to

Demon of Song - it's not at all clear.

In general, further we can pass and visit the actual

the Shrine of Amana and collect the gifts.

But, to open gate to the shrine, you need to be hollow.

And we go to the following location look for Vendrick - Undead Crypt.

Near the first bonfire we will again appear talking stump

Aldia, with his elusive philosophy.

I will not even try to convey the essence of his mutterings

because he will not tell nothing important for the story

just chunter about the meaning of my existence,

obviously preoccupied with senselessness his own being.

The most valuable thing to us here Aldia say is

Vendrick is somewhere here close, so go to the depths

Crypt of the Undead.

This is the resting place for the various undead, it's dark

and no one happy with the bright light.

Making a short pass to the bonfire and getting ready for a meeting

with the most faithful defender King Vendrick -

Sir Velstadt.

After Dragonfly 44: Astronomers Now Find Galaxy with NO Dark Matter - Duration: 5:59.

Hello Space Fans and welcome to another edition of Space Fan News.

In this episode, the case for proving that there is no such thing as dark matter just

got a lot harder.

After announcing the discovery of an ultra-diffuse galaxy made up of 99.99 percent dark matter

called Dragonfly 44, the same team of astronomers have now found another galaxy with almost

NO dark matter.

A while back, around 2015 or so, astronomers had announced the discovery of a faint galaxy

that had almost no stars but contained a lot of dark matter, in fact, almost the whole

thing was made up of the stuff.

This galaxy was so strange that astronomers have been looking for more like it: faint,

diffuse and has roughly the same size and mass as our galaxy.

They named the galaxy Dragonfly 44 after the telescope that observed it and you can learn

much more about it in the video I made about it and posted a couple of weeks ago.

Well this week astronomers looking at a galaxy first recorded back in 2000 and has the catalogue

name NGC1052-DF2 have announced that they think they've found another ultra-diffuse

galaxy that appears to have no dark matter in it.

So to be clear: the same team of astronomers have found an example of an ultra-diffuse

galaxy that's almost entirely dark matter to one that doesn't seem to have any.

Now I know just what you're thinking, 'How in the hell can astronomers possibly know

if a galaxy has 99.99%, 50%, 10% or no % of dark matter in it?'

It all comes down to how galaxies rotate.

Galaxies with lots of dark matter have stars that travel quickly around the galaxy's

core while galaxies that don't have that much travel slower.

Think of it this way: if our Sun were to suddenly get four times more massive, the Earth would

have to move twice as fast to stay in its orbit.

Same thing here, if a galaxy is rotating fast, it must have lots of dark matter in it or

else all the stars would fall in toward the center.

Adding up all the stars we can see, and include the gas, dust and any supermassive black hole

that might be there, still isn't enough to explain the rates at which these stars

are travelling.

Something else we can't see is adding mass to the galaxy and causing the stars to rotate

fast.

Nobody knows what dark matter is, but this is one way astronomers can find out if it's

there: by looking at things we can see, like stars going around a galaxy.

Dark matter is a crappy term: we could just as well call it transparent matter or WTF

matter or unknown matter or clear matter but the point is, we can't see it directly but

astronomers think it is an actual thing that galaxies have and not just some misunderstanding

about how gravity works.

Well this discovery of a galaxy with almost no dark matter strengthens the case that dark

matter might actually be a thing, a particle or something tangible associated with large

scale structures in the universe and galaxies.

How?

Well given what I just said before, if a galaxy is spinning fast, like in Dragonfly 44, it

must have a lot of dark matter and if it is spinning slowly, like in the galaxy studied

in this research, then there must not be much dark matter.

The stars in this galaxy, or more accurately the globular clusters observed in this galaxy

(because they are brighter than stars) are moving so slowly that astronomers aren't

even sure the galaxy is rotating at all!

Remember what I said ultra-diffuse galaxies were: very faint, very spread out and fluffy

(about the size of our Milky Way) and don't have many stars.

So these ultra-diffuse galaxies are really teaching us a lot about dark matter, and as

you can imagine, astronomers are very eager to find more of them.

If you go down the road of saying dark matter doesn't exist and there is something we

need to modify about gravity to explain how galaxies rotate, well now you have a problem

because NOW you have to explain this galaxy, which isn't rotating at all.

The laws of physics you'd have to come up with to explain fast rotating galaxies now

suddenly doesn't apply to this one, so now what?

Here is a galaxy that is rotating exactly as you'd expect it to if there weren't

dark matter in it.

This discovery that the ultra-diffuse galaxy NGC1052-DF2 is barely rotating, if at all,

highly supports the idea that dark matter is a thing that galaxies have: they either

have dark matter or they don't.

And if it's a thing galaxies can have, a property of the galaxy itself, then there's

probably a particle associated with that thing.

So now it just got a lot harder to explain away dark matter.

Or rather clear matter, I think I like that term a lot better.

Sounds like a very refreshing beverage.

Maybe WTF Matter….

That's it for this episode Space Fans.

Please let me know what you think about the new SFN format and give me your theories on

what you think Dark Matter is in the comments below.

I want to thank all Deep Astronomy Patreon Patrons who are keeping the lights on in SFN

HQ, thank you all for watching and as always, Keep Looking Up!

Hubble finds a Galaxy lacking Dark Matter - Duration: 5:01.

Using the NASA/ESA Hubble space telescope, Astronomers have found a galaxy that appears

to contain almost no dark matter.

This discovery of the galaxy NGC 1052-DF2 challenges currently-accepted theories of

galaxy formation and provides new insights into the nature of dark matter.

Hubble helped to accurately confirm the distance of this Galaxy to be 65 million light-years

and determined its size and brightness.

It is larger than the Milky Way, but contains about 250 times fewer stars, leading it to

be classified as an ultra diffuse galaxy.

We all know what a galaxy looks like, right?

It's a huge

collection of stars and other matter that's shaped like a

spiral or an ellipse, and if you're an astronomy fan you

probably know that most of the mass is from invisible,

mysterious material called dark matter.

Well, NASA's Hubble

Space Telescope just took an image of a galaxy that is none

of those things.

For the first time, astronomers have strong

evidence for a galaxy not having a significant amount of dark

matter.

Most astronomers currently believe that dark

matter plays a fundamental role in our universe and the

formation of galaxies.

This is because galaxies seem to have a

lot more mass than what we can account for based on just the

stars we see.

How much mass is in a system is determined by

measuring the speed at which galaxies rotate or individual

stars in a galaxy move.

Without the gravity from that mass, a

galaxy would fly apart if everything in it is moving as

quickly as we observe it moving.

Decades of research have led

astronomers to the extraordinary conclusion that 85% of the mass

in our universe is invisible in all wavelengths of radiation,

and that it's composed of matter that does not contain protons or

neutrons or any type of particle we've detected before, and that

this invisible material is all around us, passing through us

without interacting with regular matter except by gravity.

For

some, that's a tough pill to swallow, and a minority of

astronomers wonder if maybe we just don't completely understand

how gravity works.

If that were the case, and it was an inherent

property of gravity that causes galaxies to move the way they

do, then we could expect all galaxies to behave the same way.

In other words, they would all seem to have about the same

portion of "dark matter."

But with the galaxy in this Hubble

image, astronomers looked at the velocities of ten globular

clusters in the galaxy, each a spherical collection of hundreds

of thousands of stars, and calculated that their movements

can be accounted for entirely by the mass of the visible material

in this system.

That means this galaxy has little to no dark

matter.

Strangely, this absence of dark matter actually provides

evidence that dark matter is real.

It shows that dark matter

isn't always coupled with regular matter – that it's

something separate.

You can have regular matter without dark

matter.

This galaxy is really weird even beyond the dark

matter thing.

You may have noticed you can see straight

through it.

That's because this galaxy is what's called an

"ultra diffuse galaxy," which as the name implies, is extremely

low density.

This galaxy is about the same volume as our own

Milky Way galaxy, but only has about 0.5% the amount of stars.

Though astronomers have known about ultra diffuse galaxies

since the early 1980s, they can be difficult to find since

they're so faint.

A team of astronomers is using an array of

telephoto lenses called Dragonfly to seek out these

ghostly-looking objects.

They obtained observations from

Dragonfly, the Sloan Digital Sky Survey, the Gemini Observatory,

and the Keck Observatory, then requested time on the Hubble

Space Telescope to take a closer look at this unusual galaxy.

Having images and data from multiple sources allowed the

team to determine that this galaxy does not have a

significant amount of dark matter.

This was definitely

surprising to find.

No other galaxies so far have appeared to

be so lacking in dark matter.

In fact, other ultra-diffuse

galaxies seem to have an overabundance of dark matter.

The same team who studied this galaxy discovered a different

ultra diffuse galaxy in 2016 that they calculated was 99.9%

dark matter.

Yet another weird thing about this galaxy – the

globular clusters used to measure the galaxy's rotation

are way brighter than normal globular clusters.

The

researchers have written a different paper that focuses on

just these oddball collections of stars.

So, this is a very

strange galaxy in several ways.

Astronomers will be looking at

Hubble observations of other ultra diffuse galaxies to see if

there are any other examples of galaxies with unusually low or

high amounts of dark matter.

With more samples, astronomers

will be able to better understand the nature of dark

matter, the formation and evolution of galaxies, and the

overall structure of our universe.

PLEASE LIKE, SHARE, COMMENT & SUBCRIBE videos! Thank you very much

But tonight we decided it'd be best for us to watch it separately Clyde's got a huge crush on my sister Laurie it gets awkward

I'll just go watch my show and dad's crummy old black-and-white TV. Where's be so heavy here you are now

Deserves a cookie. Oh, thanks so anyway

You're glowing

News the bioluminescent DNA of a quarry a Victoria jellyfish into a cookies I call them glowy O's besides now we can see

Okay, everyone. Huddle around you forgotten me

Can I go flip the circuit breaker and get the lights back on in the basement?

All right come on

Hey something in the basement. I'm not going down there. Oh, you're scared of the dark

I am NOT. You're the one who's scared. I'm not afraid of anything though

Didn't vote well Lincoln. What's it gonna? Be it's sword to choose you have until the end of the day to decide

Now I've done it if I choose Aloha Beach five of my sisters are gonna be mad at me wow thanks Lola

Hey little, bro

Just thinking hello the pressure you're under to decide

Take a nice long one. I cleared the balconies catacombs

You guys aren't trying to get my vote for a loja Beach. I am then to my earlier statement

Deciding where to go for our vacation might not be so rough after all

For my babe I

Love that cow

Welcome to your own pride

soap no more cocoa before bed

What's going on waiting in line for the bathroom better get used to standing in lines if you're gonna vote for Dario

Guys FYI Santa my crack does not make me one of the word of advice

Blowing chunks does not make me want to vote for Dairyland

Giving me a sunburn is not the way to win my vote huh sodium, honey

Well the bathroom I

Didn't ice pack

Great I was afraid of making five with my sisters mad at me

But now Oh norm there's only one thing left to do and the pooping in the woods

That's still the only reason I go. This is literally going to be the worst vacation ever

I'd say everything turned out a okay

Really

That's right, I said to meet me at 3:30 in front of my house, and we're gonna settle this

Whew what a milling line better

Well if you use chunky you're gonna have to you

Hold it right there he wore cargo shorts on your date that is literally a layup with somebody

Thanks

Lincoln honey. I need you to take out the trash okay mom five minutes not by Schlampe in there

I can't find you anywhere. Nope have you tried looking on your desk so smart

What's up with that hat oh?

This these are all. Oh, yes, I'm sure it's just I assumed that being of average intelligence. You didn't place it there yourself

Therefore I can only deduce that someone has been picking

You're being picked on Lisa I thought you weren't going to say anything know what I can't was I did not have

That's how you're gonna take them down

Sometimes I scare even me

Jokes are always big too like you're so ugly you have to trick-or-treat over the phone what?

Oh

Girlfriend that's ridiculous she shoved a sandwich down my pants

All they do is metal their girls linking they don't want about these things than we do it's a scientific fact

So go get her Romeo you still got it

Sorry buddy our Val she gave the shiz for that shiner x-ray machine

We're always wrong huh?

Sorry lame-o okay, maybe just this one time my sisters were right

through it. That's because this galaxy is what's called an

"ultra diffuse galaxy," which as the name implies, is extremely

low density. This galaxy is about the same volume as our own

Milky Way galaxy, but only has about 0.5% the amount of stars.

Though astronomers have known about ultra diffuse galaxies

since the early 1980s, they can be difficult to find since

they're so faint. A team of astronomers is using an array of

telephoto lenses called Dragonfly to seek out these

ghostly-looking objects. They obtained observations from

Dragonfly, the Sloan Digital Sky Survey, the Gemini Observatory,

and the Keck Observatory, then requested time on the Hubble

Space Telescope to take a closer look at this unusual galaxy.

Having images and data from multiple sources allowed the

team to determine that this galaxy does not have a

significant amount of dark matter. This was definitely

surprising to find. No other galaxies so far have appeared to

be so lacking in dark matter. In fact, other ultra diffuse

galaxies seem to have an overabundance of dark matter.

The same team who studied this galaxy discovered a different

ultra diffuse galaxy in 2016 that they calculated was 99.9%

dark matter. Yet another weird thing about this galaxy – the

globular clusters used to measure the galaxy's rotation

are way brighter than normal globular clusters. The

researchers have written a different paper that focuses on

just these oddball collections of stars. So, this is a very

strange galaxy in several ways. Astronomers will be looking at

Hubble observations of other ultra diffuse galaxies to see if

there are any other examples of galaxies with unusually low or

high amounts of dark matter. With more samples, astronomers

will be able to better understand the nature of dark

matter, the formation and evolution of galaxies, and the

overall structure of our universe.
