Can Our Universe Be in an Infinite Loop?

In summary, the conversation discusses the possibility of a multiverse existing and our universe being doomed by its own gravity through the "big crunch" and then being reborn through a "big bang". It also brings up the idea that at the end of the crunch, known laws of physics may not exist and there could be a force that repels energy from other universes. The question is posed whether our universe is in an infinite loop within the multiverse. The concept of an infinite loop universe, also known as the cyclic model, is not well accepted by physicists.

Just a question, I am by no means a astrophysicist... just a lowly thinker who doesn't think much

IF
a multiverse exists and we exist in a multiverse

AND
our universe in the end is doomed by our own gravity, resulting in "the big crunch"

AND
there will be another (or infinitely) big bang due to the crunch...

AND
if all known laws of physics do not exist at the end of the crunch

AND
that some force at this point, may exist strong enough to repel energy (visible light, micro, etc) from other universes, kinda the opposite of what a black hole does?...

what i am getting at is if this is all possible: multiverse, big squeeze, big bang... can it be possible that our universe is in a infinite loop within a multiverse?


once again I am only an occasional reader of some basic astrophysics and basic quantum so don't be too harsh...

The multiverse question and the infinite loop question are different questions and they might not be dependent on each other.

The Infinite loop universe is a theory in cosmology known as the http://en.wikipedia.org/wiki/Cyclic_model" . I don't think it's well accepted by physicist

1. Can our universe be in an infinite loop?

There is currently no definitive answer to this question. Some theories, such as the Big Bounce theory, suggest that the universe could go through cycles of expansion and contraction, potentially leading to an infinite loop. However, other theories, such as the Big Crunch theory, propose that the universe will eventually come to an end rather than repeating itself.

2. What evidence supports the idea of an infinite loop universe?

One potential piece of evidence is the cosmic microwave background radiation, which is a remnant of the Big Bang. Some scientists believe that the pattern of this radiation could indicate that our universe is in a cycle of expansion and contraction. However, this is still a highly debated and speculative topic in the scientific community.

3. Is an infinite loop universe possible according to the laws of physics?

Again, there is no clear consensus on this question. Some theories, such as the oscillating universe model, propose that the laws of physics allow for an infinite loop universe. However, other theories, such as the heat death theory, suggest that the universe will eventually reach a state of maximum entropy, making an infinite loop impossible.

4. If our universe is in an infinite loop, what happens to us in each cycle?

It is impossible to say for certain what would happen to us in each cycle of an infinite loop universe. Some theories propose that our memories and experiences would be wiped out and we would essentially be "reborn" in each cycle. Others suggest that we would continue to exist in some form, potentially in different universes or dimensions.

5. How does the concept of an infinite loop universe relate to the idea of a multiverse?

The concept of an infinite loop universe is often tied to the idea of a multiverse, which proposes that there are multiple parallel universes coexisting with our own. Some theories suggest that an infinite loop universe could be just one of many universes in a larger multiverse, each with its own unique characteristics and cycles.
