if yes

then tell me how n theories u support

Answers:

Imagine that somehow time travel is possible. Now we are travelling in to the past. Today morning I came to know the concept of time dilation. I also met a girl today and fell in love with her. Now once I start travelling into the past, it must mean that my brain also travels into the past. I think it might mean that I must start forgetting. Once I reach yesterday evening I must have no idea that I learnt time dilation or I fell in love with a girl today morning. So, who knows we might be travelling in time. We might have gone to 2020 and come back here again. Is this not possible?

Answer2:

Relativity:

You need to understand that relativity does not tell us that we can move into the past near the speed of light. It simply says that our time will be slower than the time of a person at rest(or moving slower).

Basically this means that if you start your trip at 12 am and fly very close to the speed of light for 1 second, your time will be 12:00 and 1 sec, but a stationary observer will have gone ahead by hours.

Answer3:

I think time travel is not possible becoz Time itself ia s measure and not a dimension.How can you say what is exactly i sec period it is based on nothinn but our ancients or even modern scientist's laws.i say that i sec is the time that is required to travel from say A to B.So there is no physical defination as such for all units.

So to travel back or forward in time is meaningless

Answer4:

Relativity is based on Einstein's famous mass-energy equivalence: E=Mc^2

Relativity tells us that the work done in accelerating a mass (what we call kinetic energy) is reflected by a small increase in the mass of the body, by an amount equal to the energy increase. Consequently, as the mass of the body has increased, more energy needs to be used to further accelerate the body. On integrating, we get the formula:

m = m0/sqrt(1-(v/c)^2)

where 'm0' is the rest mass of the body and 'm' is the mass of the body at the velocity 'v'.
