is it possible? What components would i need to create a time machine? It seems possible, at least in the near future.

bump. i thought this board new stuff about science....

Yes, it's possible, but it isn't plausible. Massive energy sources, wormholes, that sort of thing.

You could only exist for a plank, simply impossible for anything more, now you could make a system that would carry you along the path but the fps would be shit and the dialog would be all choppy, everything would be immovably, phys fags know why, and if we're 'violating' a relativity doesnt mean all scopes of reason of existence are out the window, but you could get a good peak in the ladies washroom OP, sorry, didnt mean to offend, mens

If you could create a machine which is more massless than a photon and give it some energy to go faster than light then maybe. But there's no such thing which is more massless than a photon (yet?).

Alright, fine. Find the relative motion of the object (Or group of objects) you wish to time travel with/on.

Now decrease your speed relative to them. Over timescales incomprehensible to humans, the infinitesimal time dilation they will experience will add up.

Happy?

>> No.5586991

Let's say you were to make a time machine to physically move everyone to the past or future. Let's think about what we would need. For this example, let's use cosmic string theory and wormhole theory. A cosmic string is a string-shaped "crevice" which has an extreme mass. You can think of the crevice as something the same width as an elementary particle and at least the length of a galaxy.

It has immense mass, giving it the property of space-time distortion. If you were to travel through that distortion, you could make a full rotation around the string in less than 360 degrees. In short, you can do something resembling a warp. This is called a space-time angular deficit. When you pass through an area of angular deficit, transit time becomes zero. By applying this, once the cosmic string moves approaching light speed, according to the theory of relativity, time will flow slower for the cosmic string in relation to its surroundings. Therefore, passing through the distorted area of angular deficit would cause the zero transit time to become negative. In other words, it will be the "past" after transit.

So if you use two cosmic strings, you can do a space deficit jump. If you revolve back to your original location, you can return to the same time you started revolving. Also, so nobody misunderstands, cosmic string theory is different from superstring theory. With that out of the way, you need three things in order to travel to the past with cosmic string theory.

1. Cosmic strings. Two are necessary. (they are hypothesized to exist only where the universe was first formed, gl lol)
2. You need the energy to make them move at near light speed.
3. A spaceship able to go all the way to the cosmic strings. The time traveler must be on board.

>> No.5586992

There are two holes ties together by a tunnel. Transit time through the tunnel is zero. No matter how far away the second hole is. But there is a catch, the tunnel suffers from super gravity, and collapses as soon as it opens. Which is why we need something to negate the effect of gravity. The so called "exotic matter". It's a substance with negative mass, which repels gravity.

The wormhole tunnel is all squished and squashed like if you made a fist. In order to pass through, you need something inside my hand to oppose the "grasping force" so that I cannot squish anymore. If you stabalize a wormhole with exotic matter injection, teleportation becomes possible. For example, let's say there's a wormhole entrance in your room to whatever town a few towns over. Now imagine the hole in the town a few towns over goes all the way to the end of the universe at near light speed and once it reaches the end, it immediately pulls back to your room. According to the theory of relativity, time slows down for objects moving at the speed of light. Meaning the hole that returned to your room would be further in the past than the hole a couple towns over.

The prerequisites for wormhole theory are simpler than the ones for cosmic string theory.

1 The wormhole itself. They may exist somewhere int he universe, but nobody has seen one.
2. The energy required to move a wormhole to the end of the universe and back near light speed.
3. Exotic matter, which, by the way, has not been confirmed to exist.

Entropy is the only quantity in the physical sciences that seems to imply a particular direction of progress, sometimes called an arrow of time. As time progresses, the second law of thermodynamics states that the entropy of an isolated system never decreases. Hence, from this perspective, entropy measurement is thought of as a kind of clock.

in order to do anything akin to time travel, you'd have to decrease entropy, which is impossible atm, as the set of macroscopic variables one chooses must include everything that may change in the experimen

It's irrelevant to relitivity, they're maintaining an entirely vectoral based boson at the 'core' of their mass.

Physics hasnt really relized that math has already surpassed them do to the fact that math is simply to far ahead for physics to recognize

>is it possible?

No. There is no "future" or "past"

there is only the present, and it just changes in structure.

To go to the past you would have to re-arrange all matter to a previous formation/structure. That's all.

So no, we can't do that unless you are omnipotent

As of now you can only travel forward in time. The closer that an object gets to the speed of light the slower that it ages in relation to anything else that is moving slower.

godels work on relativity seemed to indicated the potentiality of time travel, of course that could be simply due to einsteins flawed jew science.
