Hi i have a few questions about black holes. Are black holes just stars that are so big, and have so much mass that no light can escape them? Do black grow in size, or are they just an infinite small point of space?¨ Can black holes die? are they actual holes, or are they spherical? can you travel faster than the speed of light? I know that light bends to gravity, so in theory if you could get light to travel around a massive object, like a star or a planet. could you go straight through the object, like a tunnel and catch up with light. does gravity lessen as the universe gets bigger?
