Do the #BlackFriday lines suck? We’re asking the same question about black holes...why do they suck...or do they? There are many cultural myths concerning black holes. They have been portrayed as time-traveling tunnels to another dimension, or as cosmic vacuum cleaners sucking up everything in sight. Black holes are really just the evolutionary end points of massive stars. At a distance, black holes really don’t have more gravity than normal objects, so at a distance they really won’t suck things in any more than a normal object at the same mass.
