Fast travel is possible at the speed of light Scientists.

The fastest man-made spacecraft at the moment is the Parker Solar Probe, which has a speed of 4.5 million kilometers per hour. At this speed, Islamabad to London can be reached in 20 seconds, and the plane can circle around the world in five and a half minutes. But if it is sent to the nearest star from Earth, it will take more than six and a half thousand years to reach there.Obviously, this journey is not possible in any way because it will require more than two hundred generations of human beings. So if man ever wants to travel easily on the planets, he will need more speed than light. But speed beyond light is still possible only in science fiction.The characters in the series "Foundation" by the famous science fiction writer Isaac Izimov travel around the solar system, between the planets or in the whole universe with the help of jump drives.

As a child, I read as many stories as I could.I am now a theoretical physicist and a student of nanotechnology, but I am still interested in how a person will one day travel in space.
In popular films such as 'Instructor' and 'Thor', some astronaut-like characters use fictitious methods to reach the solar system in the blink of an eye. One way that Star Trek fans will be familiar with is warp drive technology. Warp Drive is theoretically justified, but its practical form is still a long way off. But now, in March of the same year, two such articles made headlines, claiming that a solution had been found to one of the many obstacles to the warp drive theory and practice.But how do these theoretically possible warp drives work? Will man soon be riding on them and roaming in space?

Compress and Expand.

• Physicists' current understanding of time and space is based on Albert Einstein's theory of relativity. According to the theory of addition, time and space (time and space) are interconnected and nothing can travel faster than the speed of light.

• The theory of addition also explains how matter and energy change time and space, meaning that heavier objects such as planets and black holes adapt to time and space. This is the change you feel in the form of gravity.

• Early science fiction writers Campbell and Izimov attributed the slowdown to this change.

• What would happen if the spacecraft could reduce the distance it had to cover and spread space and space behind it in the process? Star Trek dubbed the idea Warp Drive.

• Mexican theoretical physicist Miguel Alcoubere proved in 1994 that with the addition of theory, it was possible for spacecraft to reduce the proposed distance by pressure and expand the space and space behind them in the process.

• What does it mean? Suppose there is a hundred feet long window in a field. If you walk at a speed of one second per foot, you will reach from one end of the window to the other in a hundred seconds.

• But if you pull the window hard and bring it to you, you will now reach from one end to the other in just one second.

• This theory does not contradict the laws of addition because your speed did not exceed that of light. Alcubera proved that the warp drive shown in Star Trek is theoretically possible.

• Now we come to Proxima Centauri, right? Unfortunately, there is a problem with the Alcubier theory of reducing time and space from stress: it requires negative energy (negative energy) or negative mass (negative mass).

• Alcubera's proposed warp drive will create a smooth time-and-space bubble around the spacecraft, and time and space will rotate around the bubble to reduce the distance. An example of this is the process by which you pull the window and bring it closer. The difference is that in this case the house will shrink.

• The warp drive will require a negative substance, or a dense circle of negative energy, for this process. Physicists have never discovered a negative mass, so negative energy is the only way left.

• To generate negative energy, Warp Drive will use large amounts of matter to create an imbalance between particles and antiparticles.

• For example, if an electron and an anti-electron appear near a warp drive, one of the particles will get stuck in the material and cause an imbalance.

• This imbalance will lead to dense negative energy. Alcubera's warp drive will use this negative energy to create a time and space bubble.

• But warp drives require a lot of material to produce the necessary negative energy. Alchebury estimates that a 100-meter bubble warp drive would require all the visible matter in the entire universe.

• In 1999, physicist Chris van den Broek observed that expanding the bubble internally and keeping the outer surface permanently uniform would significantly reduce the amount of energy required to reach the size of the sun.

• This was an important development, but it is still far from practical.

A Future like Science Fiction.

• Two recent research articles, one by Alexei Bubrak and Gianni Martier and the other by Eric Lentz, offer solutions that bring Warp Drive closer to reality.

• Bobrick and Gianni Martier came to the conclusion that there would be no need for negative energy to modify time and space within the bubble in a certain way. However, this method does not allow a warp drive that can travel at the speed of light.

• Lentz also offered a proposal that would not require negative energy. He used various geometry formulas to solve the equations of the theory of addition, and thus found that warp drives would not require negative energy.
