Hello everyone. I'm a beginner with questions Can someone tell me what happens with black holes in an expanding universe? If the fabric of the universe is expanding wouldn't this result into weaker interactions inside the black hole up to the point when the black hole cannot hold the matter togeder? Wouldn't this result into a big explosion caused by interparticle forces overcoming the gravitational force? If so then wouldn't this contradict the idea that nothing escapes a black hole? Thank you.
