Black holes
- objects of extreme density with such strong gravitational attraction, that even light cannot escape
- formed by the collapse of individual stars
- small black holes and the more popular supermassive black holes
- thought to lie at the center of each universe
- gather mass from dust and gas around them
- "event horizon" is boundary around mouth of black hole where light loses its ability to escape
- objects aren't sucked into black holes, they fall into them
Worm holes
- a theoretical entity in which space-time curvature connects two distant locations or times
- not traveling faster than light, but taking a short cut through the fourth dimension, hyperspace
- in theory, they would collapse before anything could travel through them, but still most loved physical phenomena by sci-fi authors
- recent calculations suggest we may be able to prevent collapse of worm holes by using "exotic matter", which contains negative energy
So, what do you think? Do you believe worm holes exist? Would you take the chance and travel through space or time by worm hole?
