5 Theories On What Lies Beyond The Observable Universe

23 Mar 2018

Have you ever thought about how big the universe is? Thanks to our continuously updated high-tech gadgets, astronomers can see much of the planets and stars in our galaxy as well as other formations in galaxies millions of light years away.

What prevents us from seeing further into the universe is the technology astronomers use, mainly telescopes, because they are not yet powerful enough to focus on items that may be billions of light years away from Earth. Also, the universe is continually expanding. Thus, the light from distant galaxies could take many years before it reaches the eyes of Earth’s astronomers.

For now, scientists can only see a limited amount of the universe from Earth (this is called the observable universe), while the actual size of the universe is at least 250 times larger than what they can see. So, what lies beyond our observable universe?

5 Infinite Universe

infinite universe

Many astronomers believe that beyond our observable universe is just an endless expanse of stars and planets. This would imply that every possible thing you could think of exists. For example, there may be an exact replica of Earth, but the only difference between that world and this one is that you decided to take two sips of water right now instead of one.

Statistically, this would also mean that there is bound to be extraterrestrial life on another planet, either intelligent or unintelligent. As of right now, the universe could be infinitely expanding within itself, which would mean that we will never be able to see the end of it.

Due to the reasoning that astronomers have not yet detected any sort of border or boundary that shows the end of the universe, it is only logical to theorise that the universe may not have an end at all.

4 Dark Flow

Recently, astronomers detected galactic clusters that were travelling millions of miles per hour in the same directions towards something mysterious. Astrophysicists gave this yanking occurrence the name “dark flow”.

Unfortunately, astronomers and scientists have yet to determine the cause of dark flow and are puzzled by what could be pulling all this matter and energy past our cosmic horizons. In the standard model of cosmology, it is highly unlikely that formations significant enough to cause a tilt in the space-time continuum would all slide together in the same direction because the universe is supposedly uniform on larger scales.

One possible cause of this movement is that a large structure beyond the observable universe is exerting a gravitational pull strong enough to drive other galaxies closer to it.

3 Black Hole

One of the most interesting hypotheses is that we are living inside a black hole. Astrophysicists explain that there is a point where matter can no longer be crushed in a black hole. This process stops because black holes spin so fast that the compacted matter will gain a significant amount of torsion.

In the end, the compacted matter will be small, heavy, and ready to pop like a spring. When it does spring, it will turn into the Big Bang and create a new universe. This would mean that our universe was created inside a black hole and that the black holes that we find in our universe are links to other universes.

2 Multiverse

multiverse

Imagine that you are blowing bubbles and that our universe is inside one of those bubbles. Essentially, that is exactly what this theory is about: our universe is situated inside one bubble, and other universes are situated inside other bubbles nearby.

What you get in the end is a multiverse that makes up outer space. Inside each universe is infinite space, with infinite possibilities, and has its own laws. Even if you tried to go to the edge of the bubble, it would be infinitely expanding so you would never reach it. Unfortunately, this means that we won’t be able to jump from bubble to bubble no matter how fast we went.

Unless astronomers learn of another way to jump the space-time continuum, this theory will remain unsolved. Although, some theorists think that if these bubbles were to come in contact with each other, they could potentially create a Big Bang like the one that created our universe.

1 Nothing

nothingness

Because astronomers aren’t able to see past the observable universe, there is a theory that beyond what we see is nothing. Even if the universe were infinitely expanding, it could be expanding into nothing.

The language is quite tricky because the universe is defined as “everything” and nothing is sometimes defined as “empty space”, “non-existence”, or a “vacuum” depending on the person you ask.

Nothing would mean it wouldn’t have any explanation or cause whereas something must always have a purpose or reason for existing. As Occam’s razor states, the simplest theory is most likely the correct one and what could be simpler than nothing?
