How does the expanding universe relate to the Big Bang?

The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.

Is it correct to think of the Big Bang as having happened at a specific point in space?

The simple answer is that no, the Big Bang did not happen at a point. Instead, it happened everywhere in the universe at the same time. Consequences of this include: The universe doesn’t have a centre: the Big Bang didn’t happen at a point so there is no central point in the universe that it is expanding from.

Will the universe always expand?

Until recently, cosmologists (the scientists who study the universe) assumed that the rate of the universe’s expansion was slowing because of the effects of gravity. However, current research indicates that the universe may expand to eternity.

Does it make sense to ask if the universe is expanding what is it expanding to?

The universe is everything, so it isn’t expanding into anything. It’s just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there’s no center they’re expanding from and no outer edge to expand into anything else.

What did the universe expand into after the Big Bang?

There was no place outside of the Big Bang, so it was not expanding into anything. Rather, all of space began expanding, everywhere. That is why galaxies appear to be moving away from us in every direction. Any observer, anywhere, would see the same thing.

How do we know space is expanding?

The farther away an object is, the faster it appears to move away from an observer, suggesting that space itself is expanding (rather than objects simply moving through space at a steady rate). [ Big Bang Theory: 5 Weird Facts About the Universe’s Birth]

Did the Big Bang really explode from a point?

TV documentaries invariably show the Big Bang as an exploding ball of fire expanding outwards. Did the Big Bang really explode outwards from a point like this? If not, what did happen? The simple answer is that no, the Big Bang did not happen at a point. Instead, it happened everywhere in the universe at the same time. Consequences of this include:

What is the centre of the universe?

The universe doesn’t have a centre: the Big Bang didn’t happen at a point so there is no central point in the universe that it is expanding from. The universe isn’t expanding into anything: because the universe isn’t expanding like a ball of fire, there is no space outside the universe that it is expanding into. In…
