# Universe as a black hole - how did everything escape? [duplicate]

While listening to physics lectures, they glossed over things escaping from black holes insinuating it doesn't happen other than radiation... When talking about the period between Planck Epoch & 380,000 years afterward, this seems to disagree completely with the prior statement.

If we agree at the Planck epoch all matter was extremely compact, such that light were not able to escape for ~380,000 years. Isn't this by definition a black hole? After 'it/everything' expanded such that the entire system could no longer hold light back, there "was light". Yet at the same time entire galaxies (or the matter that made them) and smaller black holes emerged.

So if everything now present came from a place which was once a black hole, doesn't that prove things escape from them?
