The Big Bang also has an information paradox
Information paradoxes are not unique to black holes
Suppose you were transported back in time to where it all began. No, I don’t mean your birth. Further back. Back to a time when there was, well, nothing. Literally nothing as far as we know, not even time itself. The time of the Big Bang.
As far as we know, the universe started as an infinitely dense, infinitely hot point of matter and energy which then rapidly expanded. If you were to travel back to that time, you would also be compressed into an infinitely dense and hot point as well, not unlike being pulling into a black hole singularity.
Another similarity between the Big Bang and black holes is that both have an information paradox. The one involving black holes is well known. If you throw information into a black hole, theoretically, it is never coming out and there is no way for us to extract that information in any other form by, say, observing the black hole’s event horizon.
The Big Bang information paradox is less talked about but actually similar. Simply stated, the Big Bang began as a singularity, not in space like a black hole, but in time.
Because of how the Big Bang started from exactly nothing, it has the reverse problem from black holes. Instead of information being…
