hey earthlings ever done time travel to see some old historic events, no i presume i bet you earthlings have ever even know how to do it so do i, cause i'm an earthling too but I've heard of it and i'm sharing it with you.
what is time travel is it possible or just some science fiction (ask Barry Allen) did anyone tried it or done it? lets find out
first what is time? time is he indefinite continued progress of existence and events that occur in apparently irreversible succession from the past through the present to the future, leave that aside who needs English we need physics, for us time is considers to be a dimension and time and space are a part of a new whole dimension or short we call it the space-time (and according to general relativity space and time are both fabrics which can be ripped apart with very high energy through black holes)
and now what is time travel we can tell time travel as moving from one point to other point of time either it maybe past or future to do so we need to develop some machines which can travel through time back and forth they are the time machines and yeah for the time machine to work it some mathematical formulas which doesn't exist now and to power them we very very huge amounts of energy which may be a black hole or a wormhole or some negative energy which are impossible now maybe in the future, there are no possible ways to do time travel now as you earthlings are very young civilization.
where did it all start?
every mythology of every civilization had time travel were are not gonna talk about it.
L'An 2440, rêve s'il en fût jamais (1770) by Louis-Sébastien Mercier was believed to be the first book on time travel, where people would sleep ad would wake in some other time.
and yeah Einstein talked about it in his special and general relativity theories( which we very much discussed)
what are the bottle necks now??
-> technology
we dont have the technology now for time travel to be done
-> energy
for the time machine to work it needs some fuel and that fuel should have very high amounts of energy like some black holes and wormholes or according to general relativity we can travel back in time when we can move faster than light and according to special relativity in order to move at the speed of light or faster we need infinite energy as is directly proportional to mass it would have infinite mass another which cannot be possible according to our physical laws, but it can be possible with tachyon particles and yeah there is no physical evidence of their existence.
is it really possible?
yes and no with our technology now and the universe we exist dosent allow us to do so but the future through alcubieree drives which were proposed by Mexican theoretical physicist Miguel Alcubierre based on Einsteins field equations it works by making an energy density field lower than vacuum (negative mass which is lower than 0gms) and now the spacecraft would contract the space infront of it and expand the space behind it which would push the spacecraft forward (not thrust exactly), and as it wraps the spacetime around it it would not break any laws and exceed the speed of light.
and yeah im gonna write a follow up post about the theories , paradoxes and about people who have claimed to have done time travel.
