from where the space to accomodate the universe came?

Answer 1

Logicaly there had to be something for the Big Bang to expand into. So space is required and had to be there before the Big Bang.
Perhaps a little bang was responsible for the formation of space.
The Big Bang must have initiated Time.
And Relativity theory assembled it together =now we have space time.
A Taylor must havemade some deductions and discovered that there exists a new fabric stronger than linenen fabric and must have called it Space -Time Fabric.
Therefore humans came to exist as made up of space- time.
I know that when these 2 students of Relativity met they greeded each other and said how is your space time? They really understood space time because they knew Relativity.
We cant get away from space -time it continualy expand into the infinite but finite dimensions of the Universe.

Answer 2

At the instant of the Big Bang, the matter produced moved at an alarming rate, causing space to 'appear' so to speak.

To answer this question, we need to look at the 'Space' and the 'Time' as being a fabric. They are both intertwined together. As the matter (ie. the space) was accellerated at the Big Bang, it was accellerating into Time.
In the time that had not been expanded into yet, space did not exist, because there was no matter to occupy it. Thus, being that it is a fabric, neither did Time itself. Time was stationary. It existed, but remained constant, until such a time matter occupied it, completing the fabric.

Answer 3

Space is NOT what the Universe occupies. Space is PART of the Universe.

Saying that the Universe needed to expand "into space" implies that there is a space "outside" the Universe itself, but the Universe is defined as being everything: there is no "outside". Space itself expands.

Answer 4

The energy that became the universe appeared as a vacuum fluctuation that fell behind an event horizon. Then that energy changed state, with some of it becoming radiation, matter and motion, and with some of it becoming potential energy. Space is how we interpret our experience with gravitational potential energy. In a similar way, we interpret our experience with electric potential energy as material surfaces and their textures.
