Will the universe contract back on itself?

Astronomers think a closed universe will behave in much the same way. Its expansion will slow down until it reaches a maximum size. Then it will recoil, collapsing back on itself. As it does, the universe will become denser and hotter until it ends in an infinitely hot, infinitely dense singularity.

Can you fold the universe?

So, astronomers calculate the present radius of the visible universe to be over 46 billion light years and its diameter, 93 billion light years. The result: If you can somehow fold a paper in half 103 times, the thickness equals the diameter of the observable universe, that is, 93 billion light years.

What is the maximum times you can fold paper?

The commonly accepted wisdom is that you can’t fold a single sheet of paper in half more than seven times. The problem with folding paper in half multiple times is that the paper’s surface area decreases by half with each fold.

Are We the universe looking back at itself?

Truly grasping the fact that we are the universe looking back at itself is a powerful tool in our ontological arsenal. It brings more wonder and astonishment to our curiosity knowing that the stars we see “out there” are the same atomically as the stars inside us. It comes around full-circle.

What happens to the universe when it recollapses?

The Universe recollapses in a Big Crunch. The expansion starts out rapidly, and the large amount of matter and radiation work to pull everything back together. If there’s more than enough matter-and-energy, the Universe will expand to some maximum size, the expansion will reverse to contraction, and the Universe will recollapse.

How can the universe be expanding without an end?

The universe is a three-dimensional version of the balloon’s skin. But how can the universe be expanding if there is no end or edge to it? Using the balloon analogy again, if one were to add more air to the balloon, the ant would observe other things on the balloon’s surface getting farther away.

What will be the fate of the universe?

The answer to that question, the classical reasoning went, should determine our Universe’s fate. matter and/or radiation, cannot be static. It must expand or contract, dependent on what’s inside it and in what amounts. Here’s what we thought the possibilities were: The Universe recollapses in a Big Crunch.
