In science fiction, people often run at the speed of light. But can the human body run at the speed of light? To answer the question, let’s imagine first. Imagine it is possible for humans to travel at the speed of light. The speed of light is 29 crore 97 lakh 92 thousand 458 meters per second or 98 crore 35 lakh 71 thousand 56 feet per second. More simply, 186,000 miles per second.
Humans cannot experience constant velocity. And so if you run at the speed of light you won’t notice anything. If running at the speed of light the biggest problem would be achieving the acceleration to reach that speed. Excessive acceleration forces can harm us. It can also cause human death.
Michael Pravica, a professor of physics at the University of Nevada, Las Vegas, USA, said, ‘It is very difficult for people to circulate blood at high acceleration. Most people can withstand 4 to 6 degrees of gravity or G-force for short periods of time. As G-force increases, the ability to circulate blood from your feet to your head is limited. Your blood will begin to clot. If the power is not reduced you will die. You will die from lack of oxygen in your body.
Pilots of jet aircraft or those involved in high-level g-forces must be very careful. Special physical maneuvers are taught to avoid fainting due to G-forces. When the muscles of the limbs have to be kept tight. A special suit has to be worn to withstand 9 degrees of G-force or impact for a short period of time.
Michael Pravica also said that the human body would be like a cake if it went at the speed of light in a few seconds. According to the G-Force Calculator, 6,000 magnitudes of G-Force will hit you. To safely run at the speed of light, your acceleration may be reduced a bit.

At G-force magnitude 2, it would take about five months to reach the speed of light. It will take 5 months if the path is smooth and there is no wind resistance. And if the G-force magnitude is 1, it will take you more than 11 months to reach the speed of light. Unfortunately, reaching such a high speed is almost impossible. You cannot go the speed of light unless you have a finite mass.’
According to Einstein’s theory of special relativity, an object with mass begins to increase in mass as it approaches the speed of light. If an object were to reach the speed of light, it would become infinitely massive. To maintain that speed would require infinite energy.
Although humans cannot run fast themselves, they can speed up sub-atomic or sub-atomic particles. In particle accelerators, humans can make particles like electrons travel at about 99.9 percent the speed of light. There is a big difference between accelerating an electron and slowing a person down to that speed. It would require a lot of energy, which is impossible to say.
