Do black holes really exist?

Perhaps these objects are all really dense, but don’t have an event horizon. For example the black hole in our galaxy would need to be the size of Earth’s orbit, which is a hundred times smaller than the observational limit thus far. All this evidence implies the existence of black holes, but it doesn’t prove black holes exist. read more

Black holes are extremely compact space objects that were once massive stars which collapsed inward due to the force of their own gravity. As a result, black holes are very dense. If it were not for the effect that black holes have on the objects around them, we would be unable to detect them. read more
