What happens when you accelerate a speck of dust to the speed of light in the universe?

As the velocity of the object increases, the inertial mass increases exponentially, and the inertial mass is equivalent to the gravitational mass. Experiments on the acceleration of microscopic particles have always been carried out, but no one has ever been able to accelerate a single proton, or an electron that is lighter than a proton, to the speed of light, which can be faster, infinitely close to the speed of light, but never to reach the speed of light. The speed of light cannot surpass a major breakthrough in human cognition of the laws of the universe, it is the foundation of modern physics, and a large number of physical theories are established on this basis.

Everyone is just a drop in the ocean, so small, in the torrent of society, everyone is not alone and must deal with others at all times. For the convenience of others and ourselves, it is a matter of morality that we should consider not only our own interests but also the interests of others when doing anything.

While leaving a way for others, we also leave a way back for ourselves. Even with horrific events such as the Resident Evil, Biological Extermination, Armageddon, and Global Nuclear War, nothing seems to have happened in the universe and everything remains calm. There is little to no effect on the planet itself.

What should be done after that. Even if the earth trembles slightly, thousands of people will die. It can be seen that life is so fragile that it is much easier than strangling an ant.

That's how we live, day in and day out. The second hand, minute hand, and hour hand have turned into countless dense days, illusory shadows, and finally converged into a long river of time, becoming a huge era in which we live. We are the smallest part of them.

It can penetrate the alveoli and reach the bloodstream, forming a floating band at 25 to 33 meters, and the diameter of suspended particles is related, and the diameter of dust particles is usually less than 500 microns.

According to Einstein's mass-energy equation, accelerating a grain of dust to the speed of light increases the mass of the dust and has a large amount of energy.

It is invisible to the naked eye, but a speck of dust is very fast and can penetrate the human body instantly.

There will be a burning situation, because the speed is very fast, the dust will rub and spontaneously combust, and then it will be **.

Light at a speed of 300,000 kilometers per second has long been regarded as a long-distance runner. However, in recent years, with the "faster-than-light" theory put forward by scientists, the champion of light has been greatly threatened.

Scientists believe that there must be a particle in the universe that can move faster than light, and such a particle is called a "tachyon". The mass of the tachyon is an imaginary number, and its velocity increases infinitely as its own energy is dissipated. When the energy of the "tachyon" becomes infinitely small, its speed becomes infinite, even millions of times greater than the speed of light

Scientists believe that when a tachyon moves at the speed of light in a vacuum, it inevitably leaves a glowing blue tail in the place it passes, a conclusion based on the theory of "Cherenkov radiation". Therefore, in order to find the tachyon, it is necessary to grasp its glowing blue tail.

Although scientists have tried to find various methods, it is too difficult to catch the blue tail because the speed of the tachyon is so fast, millions of times faster than the speed of light as mentioned above. Normally, by the time people find the blue tail of the tachyon, it is already gone.

Despite the belief that there must be tachyns in the universe, scientists have not been able to find definitive evidence so far.
