How Does Gravity Escape A Black Hole?
Summary
This episode explores how black hole gravity escapes the event horizon despite the cosmic speed limit. The hosts explain that in general relativity, spacetime curvature acts locally like a flowing river, while quantum gravity theory suggests virtual gravitons are not restricted by light speed. They clarify that we interact with a black hole’s past mass, which remains causally connected to us, rather than its hidden present mass. The segment concludes with viewer questions on universe simulations, galaxy collisions, and the plausibility of nested realities.
