Started as an infinitely dense point- a “singularity”

This point expanded quickly to create the early universe, about 15 billion years ago.

Fragments shot out to eventually create the galaxies and stars we see today.

Today the effects of the big bang can be seen by the way the galaxies constantly move apart. This was first observed by Edwin Hubble.

Starts in a Multiverse, an area with infinite universes.

Energy fluctuations starts to create a “Cosmic Foam”

Universes can start if there is an even amount of gravity ( negative energy) and matter (positive energy)in the foam.

From here, the Big Bang basically takes over and the universe continues to expand.

String Theory is based on one-dimensional strings that vibrate in different tones to give things their feel, look, shape, etc.

These string can be “closed” as in a loop, or “open”.

The String Theory is a theory of gravity, and a likely candidate for the Theory of Everything, which describes how quantum gravity and everything it the universe works.

The opposite of the Big Bang, the Big crunch is all the matter in the universe crashing back in on itself.

Because all the matter is crashing into itself, the heat in the universe will be enormous

Finally, everything will be smashed together into an infinitely dense point, a singularity.

The universe continues to expand until every thing in it is ripped to shreds, atom by atom, by an unknown “phantom energy”, possibly anti-gravity or dark energy, or even that over time the rate of acceleration increases so much that everything just falls apart.

Universe expands for an infinite amount of time.

Eventually, after the last stars burn out, there is no more heat in the Universe .

This would cause it to drop to absolute zero, the point where it can’t possibly get any colder and nothing can move.

There are an infinite number of universes, with possibly different dimensions and laws of physics, in the Multiverse.

There is no defined end of the Multiverse because new universes are continually created.
