Yet another time travel discussion

[DeSalvionjr]

Oh, that one's been gone around in circles about. The answer I got when I asked it once, was that it came down to which was that it came down to which was accelerating, which was experiencing an increase in energy, etc.

both are accelerating... i think?

We all know that time travel forward can be achieved with simple speed.

ummm....

The simple laws of relativity tell us this, and have been proven out. Travelers that spend many, many hours in jets flying hundreds of miles per hour will find their watches are just barely ahead of the clocks in the time zone they left from. They have travelled forward in time, even if it is by a miniscule amount.

imho this has more to do with the fact that they are further from the earth, the largest contributing object in mass. the closer you are to a large mass the slower the atoms move and thus the appearance of the slowing of time, so the people in the plane aren't moving faster in time but their atoms are moving faster giving the appearance that the are travelling faster through time. if you could park yourself beside a black hole and the rest of the universe would appear to zoom past

What if instead of just velocity, there was something else at play which we are unaware of.

I recent times science has discovered antimatter as a ying to matters yang. Anti-matter isn't noticable to our 5 senses but many physicists believe it exists and actually makes up the majority of the universe.

What if there is something like anti-velocity. No this wouldn't be moving backwards because that is just velocity in another direction. It is not moving super slow or standing still becuase the is just minimal or zero velocity.

What is anti-velocity? I have no clue, but it is the key to travelling backwards in time .

This would then prove that time travelling by machines in most movies would be impossible. It is only possible to time travel by going extremely fast, which a machine is not capable of doing.

Unless the machine spun you really really fast and instead of splating against the walls you just traveled thru time.

Where'd you get this idea from? Rota was talking about simple relativity. It happens. Really.

I don't accept the assumption that machines are not capable of traveling very fast. It's true there is a limit to our current methods of propulsion. But, that does not mean there won't be a machine capable of extreme speeds in the future.

some of the time machines are designed to accelerate all of the objects that are within the machine, at an atomic level, thus speeding up the objects without the need for motion... others create a rift it the space time continuum which allows everything outside the time machine to change while the machine itself remains stationary

however even in the science fiction community the idea that travelling at near the speed of light causes you to travel through time isn't always accepted

in star gate they travel across galaxies through wormholes and are still able to return while maintaining time sync (1:1) with their departure point. these trips would be made at very close to if not beyond the speed of light and the time line remains intact

it isn't my idea it's based on Einstein's concepts he had had theories regarding how speed and mass affected the relative perception of time

both can be used to explain the issue in plane travel

that's why i said IMHO i wasn't disagreeing with the concept i just don't accept it as the only possible answer

Jeez. Everybody's over-thinking this... we all know that all you need to time travel is:



1.21 gigawatt's of power for the flux capacitor,




a sweet ride,




and nifty travelin' gear







Jeez, ya bunch of eggheads, relax
