How to create a time machine?

Question

i know we need super fast rockets that can reach 300000km per second but how we create wormholes?

Answer 1

The effect, known as time dilation, occurs whenever two observers move relative to each other. In daily life we don't notice weird time warps, because the effect becomes dramatic only when the motion occurs at close to the speed of light. Even at aircraft speeds, the time dilation in a typical journey amounts to just a few nanoseconds--hardly an adventure of Wellsian proportions. Nevertheless, atomic clocks are accurate enough to record the shift and confirm that time really is stretched by motion. So travel into the future is a proved fact, even if it has so far been in rather unexciting amounts.
To observe really dramatic time warps, one has to look beyond the realm of ordinary experience. Subatomic particles can be propelled at nearly the speed of light in large accelerator machines. Some of these particles, such as muons, have a built-in clock because they decay with a definite half-life; in accordance with Einstein's theory, fast-moving muons inside accelerators are observed to decay in slow motion. Some cosmic rays also experience spectacular time warps. These particles move so close to the speed of light that, from their point of view, they cross the galaxy in minutes, even though in Earth's frame of reference they seem to take tens of thousands of years. If time dilation did not occur, those particles would never make it here.

Speed is one way to jump ahead in time. Gravity is another. In his general theory of relativity, Einstein predicted that gravity slows time. Clocks run a bit faster in the attic than in the basement, which is closer to the center of Earth and therefore deeper down in a gravitational field. Similarly, clocks run faster in space than on the ground. Once again the effect is minuscule, but it has been directly measured using accurate clocks. Indeed, these time-warping effects have to be taken into account in the Global Positioning System. If they weren't, sailors, taxi drivers and cruise missiles could find themselves many kilometers off course.

At the surface of a neutron star, gravity is so strong that time is slowed by about 30 percent relative to Earth time. Viewed from such a star, events here would resemble a fast-forwarded video. A black hole represents the ultimate time warp; at the surface of the hole, time stands still relative to Earth. This means that if you fell into a black hole from nearby, in the brief interval it took you to reach the surface, all of eternity would pass by in the wider universe. The region within the black hole is therefore beyond the end of time, as far as the outside universe is concerned. If an astronaut could zoom very close to a black hole and return unscathed--admittedly a fanciful, not to mention foolhardy, prospect--he could leap far into the future.........

NO man-launched macroscopic object has exceeded 50 miles/sec under any circumstances. Wormholes were invented by Kip Thorne at Caltech when Kurt Vonnegut playfully requested a plot twist (appearing as "chronosynclastic infindibula"). They looked theoretically interesting but turned out to be invalid in all cases.

Time travel, with one exception, violates causality. The universe does not tolerate contradiction. No time travel. The single exception is... wait a minute.. there it is.

The mixing of time and space, Special and General Relativity, is not a time machine. The Global Positioning Satellite (GPS) system is intensely relativistically corected for moving relative to the ground (GPS clocks appear to go slower) and being less deep in Earth's gravitational well (GPS clocks appear to go faster).

Answer 3

Wormholes are fictional constructs.
The proof that time machines can't exist is that they don't exist.
If 1000 years in the future, time travel became possible, then it would be possible for future people to return to the past and affect our time, and by so doing, affect their own future time, such that the conditions that created time travel no longer exist.
It makes for some good fiction, but that's about all.

Answer 4

The Second law of thermodynamics states that entropy must increase over time; the cosmological arrow of time, which points away from the Big Bang, and the radiative arrow of time, caused by light only traveling forwards in time.

Time has a direction - the past lies behind, fixed and incommutable, while the future lies ahead and is not necessarily fixed.

So, my conclusion is, you can`t travel back in time without violating the laws of thermodynamics and the universe. So, why a time machine?

Answer 5

We'll need far more than just rockets to attain the speed of light which is, so far, is the ultimate speed in this Universe and,will take four years to get to the closes star. Also, we would need infinite power to do so but you would die in your quest as your body would change from mass to energy as you approach the speed of light.

Worm holes are just a theory as were black holes. at one time. Black holes helps us with our research on the cosmos. Don't think there's much other use for black holes or worm holes except for a device in many science fiction plots.

Answer 6

You are a time machine. But you can only travel into the future. Sorry about that. Everything else makes good reading, but don't lose any sleep over it!

Answer 7

You cannot create a time machine. If you do, you violate how the universe works at the quantum level which means we couldn't exists at all.

Answer 8

No way to create such a machine.

Answer 9

I dont think worms holes "we" can create... I believe though that black holes are worm holes to the unknown. ... Interesting question.

Answer 10

make the wormholes yourself.
