Astronauts. For example, they have become somewhat time travelers. That is because they go into space and live on the International Space Station, sometimes spending several months at a time. Astronauts on the space station move faster than Earth, at a speed of about 5 miles (8 kilometers) per second, meaning that the astronauts on the station are a little slower than they were on the surface of the planet.
When astronaut Scott Kelly returned after spending a year in space, the age gap with his two-year-old older twin, Mark, increased slightly.
Many of science fiction interests revolve around time travel to the past. Such travel raises many questions, such as whether you can go back in time and stop a bad event. The scientist Sutter pointed out that the physics of our universe seem to prevent this from happening, at least as far as we can see and understand it, but it is surprising that some of Einstein's equations of general relativity theory may allow a return over time to the past, where this theory primarily discusses how large bodies Distortion of space-time, which we feel as we feel attractive.
So how does Einstein's theory make time travel possible? Well, one way is to break the cosmic speed limit, and to move faster than the speed of light, but this is considered a scientific abstraction, because the object traveling at this speed will have unlimited mass, and the other possibility is the formation of a "worm hole" between the points in space-time. There are more strange possibilities, such as using black holes, huge cylinders, or cosmic strings to play with the fabric of space-time.
When it comes to the past, the mathematics of general relativity theory allows some strange scenarios to happen, and through which you can end up in your past, but all of these scenarios end up in breach of other known physics, i.e. always contradict each other, so why does general relativity allow travel To the past, while other physics always jump to spoil fun? We honestly do not know.
But this does not mean that scientists give in. In 2015, Ali Ogun of the Eastern Mediterranean University in Cyprus said that holes might be possible in areas with dark matter, and this is a theoretical form of matter that cannot be seen or sensed by telescopes, but it manifests itself in its effects Gravity on other objects. His equations show that wormholes can occur in these areas, and Ogun says he is still looking for evidence, and he said that all he found is based on mathematical evidence only, and he hopes one day he will be able to find direct empirical evidence.
Even the famous physicist Stephen Hawking was fascinated by the idea of time travel before his death this year, when he discussed in the Daily Mail how a black hole could make this possible.
In general, the idea of time travel will remain theoretical at least for the time being, and this is what we conclude after reading the article, despite the scientists ’belief that it is possible to travel through time, but they are still unable to prove this with hard evidence, all they possess is a set of equations that This theory supports but is not really proven.
I think you have to wait for a long period that may be long, perhaps you could go back in time and expect a sporting event that you already learned, and betting on it to win huge sums that enable you to buy the car of your dreams and live the luxury you dream of, or to recommend your grandchildren to return you to the future if you miss it, perhaps travel Through time it will become available in their time.
In the end it is not as simple as Steve Griffin in Family Guy, you can't build a time machine and put it in your room to go on an adventure when you like it right?
