I got some questions, plz help me hi i did my indipendent study report on time travel and i have to give that report to every students and each of them will ask me 5 qestions and i have to answer them. here are some questions they gave me plz help me out. I need to find answers as soon as possible. I tried to search, but i couldn't find it. 1) Is it possible to calculate the magnitude of the gravitational field of a black hole? 2) How in a wormhole do two regions of space actually come together?? 3) Is it possible that anything could attach it self to a cosmic string? 4) If time travel was possible, would it be ethical to use that power for any means? 5) Since light is a form of energy and has no dimensions of time, wouldn’t time traveler age normally in a space craft that went light speed because time puritans (pertains) to him? 6) If wormholes are so unstable that they would collapse when light entered into them, would not there be no wormholes in the center of black holes because light can enter black holes? 7) How is it that black hole’s powerful energy is responsible for the creation of a wormhole? 8) How does a rotating black holes different from a normal one and why cannot a normal black hole be used for time travel? 9) You mentioned that a wormhole can deflect light rays, but how does this help in time travel? 10) If a cosmic string has enormous amount of gravitational pull, would not any object near it just suck in it and be destroyed? If not, how a combination of a cosmic string and a black hole simply shrink the space time? 11) How does one attach a cosmic string to an object? 12) Could you explain in more depth the idea of parallel universes? 13) If there is no dimension of time at light speed, would we become frozen if traveling at this speed? 14) Why does a black hole have high levels of gravitational force? 15) What is meant when you say that wormholes are unstable?
