Is it theoretically possible to accelerate a microscopic particle to the speed of light with an acce

Yes, particle accelerators, the most popular scientific research equipment nowadays, cost a lot of money to build, but theoretical knowledge tells us that we can only accelerate to infinitely close to the speed of light, but not beyond the speed of light, the reason is simple, the closer to the speed of light, the energy required will increase geometrically, and finally tend to infinite energy. According to Einstein's theory, it is indeed impossible for us to exceed the speed of light.

If you accelerate to half the speed of light, and two particles of that speed pass in opposite directions, won't one particle reach the speed of light relative to the other?

According to Einstein's theory, this is not possible, because the reference object is the unified ether.

Is it electrified? Linear accelerators theoretically do, and in practice seem to do, but not with cyclotrons, because when you get close to the speed of light, the kinetic mass of matter changes, and the acceleration becomes smaller until it reaches a constant velocity.

Motion greater than the speed of light abounds:

Distant galaxies that recede at high speed are moving at close to the speed of light relative to us, and the light emitted moves at the speed of light relative to us, and is close to twice the speed of light relative to itself in the direction facing us, although the speed in the other direction is much less than the speed of light, because light, like sound, travels in a vibrating medium;

In powerful quasars and black holes**, the speed of the projectile is much greater than the speed of light;

The relative velocity of the electrons in the laboratory accelerating to 99% of the speed of light in two directions is definitely not less than the speed of light, do you think that the relative velocity of these two electrons does not reach 1 times the speed of light???

You must have water in your head to think so.

There is the new LHC (Large Hadron Collider) in Europe, which has the capacity of 14T EV

As Einstein predicted in his theory of relativity, no particle with mass can reach the speed of light, which is about 186,000 miles per second (kilometers per second). No matter how much energy is added to the mass of an object, its velocity cannot reach this limit.

In modern accelerators, particles are accelerated to speeds very close to the speed of light. For example, the main injector at the Fermi National Accelerator Laboratory accelerates protons to times the speed of light. As the speed of the particle gets closer and closer to the speed of light, the accelerator increases the kinetic energy of the particle more and more.

Because, as Einstein tells us, the energy of an object is equal to its mass multiplied by the square of the speed of light (e=mc2), and increasing the energy actually also increases the mass of the particle. In other words: when there are more "e", there must be more "m".

When an object has a mass close to but not at the speed of light, its effective mass grows larger.

Both electricity and magnetism have the characteristics of opposites attracting and repelling the same sex. Then the charged particles in the electric field are also affected by the polar hail of the electric field. According to this principle, people have made a special device for accelerating particles, which is called a particle accelerator.

When the charged particles enter the accelerator, they are accelerated to the desired speed. Of course, this acceleration is not carried out by an electric field against the particle.

This is done by one or two huge impacts, but by repeated acceleration in the same direction to increase the speed of the particles. This is done in the same way that a multi-stage launch vehicle accelerates multiple times when an artificial satellite is to gain the required speed. Specifically, in a linear accelerator, several accelerating electric fields are arranged sequentially at a certain distance.

If the direction of the force of each electric field on the charged particles is the same, then the charged particles will be constantly accelerated, which is like playing a swing, if the direction of each force is consistent with the direction of the swing movement, then the swing will swing higher and higher. The particles are accelerated again and again until they finally get the required velocity. When the speed of these microscopic particles is getting higher and higher, the energy they have is getting bigger and bigger, and the particle beam requires the speed of the particles to be close to the speed of light of 300,000 kilometers per second.

These microscopic particles moving at high speed have become "cannonballs" with great kinetic energy. Ascending.

First, photons are not at rest, and the velocity of a single photon cannot be determined according to Heisenberg's principle, so you can't tell the current velocity of a photon at all.

How much. Second, from the perspective of the fluctuation of light, since the birth of light in our universe, its vacuum speed has reached the speed of light, and there is no need for acceleration.

Thirdly, only a substance with zero mass at rest can move at the speed of light, and this matter must only move at the speed of light in a vacuum. All matter with a mass at rest requires infinite energy to accelerate to the speed of light.

Fourth, the rest mass of the photon is zero, the relativistic mass of the photon is m=hv c 2, h is Planck's constant, and v is the frequency of light.

The high-energy accelerator is a powerful tool and a modern experimental method for the research of nuclear physics and particle physics. It uses an artificial method to accelerate charged particles to produce new particles with high velocity and high energy. Why do you need high-energy particles?

This is because in nuclear physics and particle physics research, it is necessary to go deep into the interior of elementary particles in order to discover their secrets. The principle of the high-energy accelerator is to make the charged particles gain energy in the electric field and accelerate, and then use the magnetic field to constrain their motion orbits, and effectively control them according to the needs of the experiment. The principle is simple, but the technology is complex.
