Anonymous users2024-02-07No, because light carries information (such as time), and what you see after the speed of light is only information, not time travel... Moreover, any object that exceeds the speed of light will become information and cannot exist in the state of matter... Very mysterious thing·· I don't know if it's true or not, after all, no one has experimented...

Anonymous users2024-02-06Impossible: Time and the speed of light are two dimensions that are not sideways, like two parallel gardens. Albert Einstein said that the speed of light was parallel to time because his senses were delusional. Is the light sensitivity of the human eye the speed of light?

Anonymous users2024-02-04There is a possibility. But after the crossing, it's just a piece of ion.

Anonymous users2024-02-03Even if it exists, at least with the current level of human technology, it should not be possible. If there really is, and it can be realized, some people travel to the past, and there will definitely be people who revise history in an attempt to change their unsatisfactory future life, and then it will be chaotic.

Anonymous users2024-02-02When an object approaches an infinitely gravitational object, time around him slows down. In fact, this is also happening in the outer space of our earth, and every GPS navigation has a few precise times, but it will be faster than a billionth of a second every year, because it is affected by the gravitational field of the earth. It's only a small effect, but our GPS navigation is really time traveling.
The big black hole at the center of our galaxy is also an example, let's say if we take a spacecraft and go around the black hole, 8 minutes there is a year on Earth, because the gravitational pull of the black hole is very large, so the gravitational force formed is also very large. If the time is slowed down and the speed of the Earth is still normal, we will be able to travel through time and space when we return to the Earth.
It is possible to travel in time and space close to the speed of light, and no object can be as fast as the speed of light, and even if it is very fast, the laws of physics will slow it down. So, if we can travel at close to the speed of light, we can also travel through time and space.
These are for the future of time travel, and the past time travel is impossible.

Anonymous users2024-02-01The relevant knowledge points behind time travel.
At this point, Einstein said "no".
However, physicists now think that it is theoretically possible, and they propose the wormhole theory in the same way that black holes were originally proposed. They define wormholes as follows: wormholes are thin tubes of space-time that connect distant regions of the universe that can also be connected to parallel or infant universes, and can provide the possibility of time travel. >>>More
From a scientific point of view, if the time we have passed now is the time scale of the fourth (largest dimension) of the four-dimensional universe, then it is impossible for us to travel back to the future, at most we can only travel back to the past. Because the largest time scale in this universe is the fourth dimensional time scale, if you live in the third dimensional world, you may still travel to the future of the fourth dimension, but if you are in the fourth dimension, then there is no future for you to cross, understand? Personal opinion, for reference only. Hope!
As follows:
1. The encounter in the years is full of the fragrance of whispering, and the sincere agreement with each other is the beacon of a lifetime. Although the pain is hidden, the torment is rolling, and there are tears from time to time, and the fingers are boundless, but the beauty after meeting is a kind of sweetness and a joy on the soul. Such a beautiful thing makes the memories turn over and over again, precipitate repeatedly, and pile up into the most beautiful scenery in the years, which is the direction of love and the destination of love. >>>More
A: At present, only Hawking's theory mentions "wormhole", which is a tunnel that can connect two different spaces, according to Hawking's "multiverse", wormholes may be connected to other universes, and may also be connected to the future or past universe, of course, this is just a hypothesis, we cannot verify it at present, the most critical limitation is that the current theoretical size of the wormhole is only 10 -30m in diameter, that is, much smaller than the atomic nucleus, according to this theory, In other words, even if the wormhole is connected to the past or the future, it is not known how difficult it is to divide yourself into elementary particles and teleport to the past, let alone how to put you back together. Einstein's theory of relativity says that the future is relative, for example, a person has traveled close to the speed of light, and returns to the earth after a period of time, although he has only stayed in the universe for 1 year, but when he returns, the earth has passed 10 years, and we can say that he has reached the future. >>>More
Aurora is when cosmic rays (such as high-speed moving protons, high-speed moving electrons, etc.) enter the earth's magnetic field, they are captured by the earth's magnetic field and do spiral motion, and the work travels to the north and south poles to collide with air molecules, and the gas is ionized and conductive and luminescent.
