Professor Stephen Hawking has given an exclusive interview and talked about what was in existence

before the Big Bang occurred 13.7 billion years ago.

The physicist talked about what pre-dated the start of the universe, and it was nothing

exciting as Hawking said there was nothing.

However, it is not as uncomplicated as it may seem, but Hawking is one of the best communicators

for science thankfully.

Hawking Talked About Imaginary Time Behaving Like A Fourth Dimension

Hawking used the Earths shape as an analogy for the curved space-time continuum.

Hawking said that the general theory of relativity, space and time, of Albert Einstein, all meet

up together for space-time continuum.

He explained that it is curved by energy and matter in it and not flat.

Hawking then went on to say that the Euclidean approach to quantum gravity had been used.

He said that the Euclidean approach, which is imaginary time replacing real time, which

then behaves just like a fourth dimension.

Hawking said that when considering the Euclidean approach, the history of the universe in the

imaginary time is like a curved four-dimensional surface like the Earth's surface but with

the addition of another two dimensions.

For anyone counting this brings it to a total of six dimensions.

The Universe Does Not Have Boundaries Hawking then went on to talk about the fact

that he thinks the universe does not have any boundaries.

This means that Euclidean space-time continuum is essentially a surface that is closed without

any end; this is just like the Earth's surface.

Hawking explained that real-time begins at the South Pole and this is a smooth point

of space-time, and here the normal laws of physics hold.

Hawking said that to the south of the South Pole there is nothing, which means that there

was nothing there before the Big Bang occurred.

The professor went on to say that just as there is nothing to the south of the South

Pole, time was not in existence before the occurrence of the Big Bang.

Instead, said Hawking, space and time expand and spread outward all from a single point

in time just like the degrees of latitude of Earth.
