you gonna have to break #1 down for me famo.
Why is time travel to the past impossible, but time travel to the future somewhat possible? Always hear people say that, but they never explain why
travel to the past is unlikely because of pardoxes. travel to the future isn't really travel to the future, its just that the closer you are to to a particular base of gravity, the slower time is, so if ur futhur away from that spacific point of gravity, and moving at near light speed you can kinda travel at a pace faster than normal time in that previous point of gravity. so technically its time travel, but what it really is, is moving faster somewhere then the normal time somewhere else. general/special relativity.
this is how the Hardon collider works, but minus the gravity, and at a subatomic partical level.
