Starts With A Bang #15: Is our Universe the inside of a black hole?

from Starts With A Bang podcast · host Ethan Siegel

Black holes are incredibly massive objects that are so dense that, from within a given region of space, nothing can escape, not even light. Yet it's arguable that from our point of view, nothing can escape our observable Universe. Moreover, even though our Universe is huge, it's also incredibly massive, and since it's expanding, it was denser and smaller in the past. Could our Universe be the inside of a black hole? And do we have evidence either supporting this or ruling it out? Find out on the latest episode of the Starts With A Bang podcast!
