Heat death before Big bang?

[ollybach]

Was there a heat death of our universe before the big bang occurred?

If so would there be another big bang after the heat death of our universe?

I have heard a theory that our universe is in a cycle of creation and destruction, but is the heat death the end all be all?

 

Keep in mind, I'm 15.

Sorry for the bad question, read up on the cyclic model, its the big crunch not the heat death.

These questions cannot be answered with the currently known laws of physics. Even the phrase 'before the big bang occurred' does not have clear meaning, because time is defined in the universe which we observe, and which exists of course only after the big bang occurred.

There are many theoretical suggestions to extend the known laws into these unknown territories, but for the lack of evidence, no one is better than others.
