How to build a time machine

[KhalaiMakhlooq]

Well to travel time you have to move the whole universe not just you because the sun is in motion the planets are in motion volcanos are exploding the oceans are having waves so the energy needed for the reconstruction of all that is required as well.

yeah you have to move the entire universe to time travel.

As time has no hard drive to store data of certain location.

Einstein gave many good things but he sucked when it came to time. Forget time travel.

You can only see the events of time in past but you cannot physically navigate through time.

yeah but it might be pre-coded, so you wouldn't need the memory

the pre-coding ensures everything is always as was and will be

so if you time travel, you are just moving through the code

If every thing is precoded then it becomes a constant and a fixed value so if you cannot change it that means you cannot time travel.

but you can. if the universe needs to move in order to time travel and this is pre-coded, then you can time travel, because the time in the universe is part of the universe. it just means you cannot do anything other the code

Yes by your concept then you are not time traveling but only observing past. You can do that. Find a very good telescopes and travel light years away from Earth and look back at Earth with telescope and you will see the light of 1970 in that telescope and observe those events on Earth.

nice, that shows time is like a kind of circle

Hope I helped you to travel in time and construct a machiene for your quest.

How to build a time machine?

any advice welcome

Is that a serious question? On PDF of all places?

Fine I'll try my best to answer seriously...

Time can be roughly defined as "the indefinite continued progress of the universe(on average) towards entropy".

Time in our universe and for all the creation within it...seems to only move forward(as far as we know). However time is relative...meaning it can pass at different rates in different reference frames(time dilation). There are two factors that can effect the passage of time...one is gravity...and the other speed.

If u r near a massive object...time will go by slower for u. For someone standing near the pyramids time will pass by slower than it will for someone standing in an open field(though by a very very tiny amount...practically insignificant). In terms of blackholes(the most massive objects in the universe) time appears to stop past the event horizon.

The other factor speed also can have an effect...the faster u get...the slower the time. If u traveled at lightspeed(somehow), no time would pass for u.

Now coming to the question of how to build a time machine...first the question should be asked "can one travel through time"? The answer for that can he divided into three parts...

Future
It is possible to travel into the future...we are all doing it right now as every second passes.

Present
U could try and slow down urself from going into the future...either by being near a massive object or by traveling really fast. An astronaut aboard the ISS marches to his/her future slower(very tiny amount) than us earthlings bcuz of the speed with which the ISS is orbiting. In best case scenario by somehow defying physics and traveling at the speed of light(while somehow still maintaining ur current mass) u can forever be stuck in the present(as in time stops passing for u).

Past
That's where things get even more confusing. No one knows definitively if it's possible to make time go backwards. No one even knows how to go about doing it...not to mention all the possible problems associated with it like the grandfather's paradox...and the fact that if time travel(into the past) is possible then why haven't we been visited by future time travelers?

So as far as ur time machine building goes...
- If u wanna go to the future...u r already headed there...one second at a time
- If u wanna stick around the present...travel so impossibly fast that u hit the speed of light(and survive somehow)
- If u wanna travel to the past...then figure out a way to do that...go back in time to before u created this thread and stop ur past self from creating it in the first place...bcuz now u wouldn't need it

does that mean tall people live longer?

thanks great advice. merry christmas

Ever so slightly...still immeasurable but theoretically yes.

thanks great advice. merry christmas

I can't tell if u have gone to some future Christmas or past Christmas. If u r in the future...send me winning lottery numbers for the next few years(of my time).

Start with a Delorean

Our time machine can be in a suzuki mehran don't you think?

I don't think you necessarily have to move the universe. You would have to get something the speed of light and travel on earths opposite rotation and in theory you would be going back in time. This is just a theory so we may never know if it actually works.
A quote from a space article.
One possibility could be to go faster than light, which travels at 186,282 miles per second (299,792 kilometers per second) in a vacuum. Einstein's equations, though, show that an object at the speed of light would have both infinite mass and a length of 0. This appears to be physically impossible, although some scientists have extended his equations and said it might be done.

A linked possibility, NASA stated, would be to create "wormholes" between points in space-time. While Einstein's equations provide for them, they would collapse very quickly and would only be suitable for very small particles. Also, scientists haven't actually observed these wormholes yet. Also, the technology needed to create a wormhole is far beyond anything we have today.

For what year? I can tell that u r new to this time travel thing...amateur. U gotta give out the winning lottery number with the future date and in a private message.
