A needle strikes the Earth at the speed of light, does it end up passing through or destroying the E

Because the inertial mass of an object increases with the increase of the speed of motion, and when the speed reaches the speed of light, the inertial mass tends to be infinite, so theoretically if a needle hits the earth with the speed of light, let alone the earth, the entire universe will be destroyed.

The result is that it will not penetrate the Earth and it will not be possible to destroy the Earth. If a needle strikes the Earth at the speed of light, it will hit a large crater on the Earth's surface, creating **.

None of them. Because the mass of a needle is small and the energy it carries is limited, when the speed of light hits the earth, it will only happen**, and it will not pass through and will not destroy the earth.

Even if it passes through the earth, it splits the earth in half. A needle flying at the speed of light has more energy than you can imagine, and it can not only destroy the earth, but also destroy the moon if the earth and the moon are exactly on the axis of the needle.

<> What happens if a needle hits the Earth at the speed of light? Will the Earth be destroyed? When a needle flies towards the Earth at the speed of light, it evades all the detection technologies that can be detected by the naked eye, the United States, Russia, China, the European Union, Japan, India, ......and all the satellites monitoring outer space have not found it.

At this time, the earth was in danger, and human beings had not yet reacted, and where the sunlight reached, the needle passed through the thick earth's atmosphere, piercing a hole in the ozone layer, like a hydrogen balloon being scratched on the surface, with a muffled ......Woohoo. The needle reacted violently with the dense gases of the atmosphere, and due to the high speed, the needle did not burn out like the usual meteorite, but only became red and entered the realm of human life systems. This one slipped through the net"needles", is deciding the fate of mankind, it wants to destroy the earth, after being cooled by the clammy and cold air, it becomes more silvery white, and it really deserves to be a big killer to destroy the earth.

Human beings never know that danger has come, and they still work, study, sleep, cook, fall in love, and enjoy life ...... as usual. The needle is still falling at the speed of light, it is choosing its target, if it is a crow, then it will surely die, and become the bird that saves the earth; If it is an elephant, it will surely die and become the elephant that saves the earth; If it is an ant, it will be cut into two pieces and become an ant to save the earth. In short, this needle can pierce everything on the earth, and all living individuals will be instantly robbed of their lives by it, and some other lifeless high-density substances are the natural opponents of needles.

If it pierces tempered glass made in China, then it will be blocked by the force, although it passes through, but the speed drops sharply; If it pierces stainless steel, at the speed of light, it can also pierce, but it also passively descends; If it pierced the manhole cover of the U.S. nuclear bomb, it would penetrate the nuclear warhead and then detonate, resulting in a nuclear accident in the United States. The earth is tenacious, it is eternal, it will escape all the attacks from the sky unharmed, the earth has the power to defend life, and a needle cannot set off any wind and waves. The needle is too small to be a threat.

A huge meteorite with a diameter of 5 kilometers only needs to hit the Earth at a speed of 1,200 kilometers per hour, and no city in the world can withstand this blow. From here, it can be seen that the volume of the impactor itself has the most direct effect on the destructive force.

It will not be destroyed, but it is likely to affect the movement of the earth's crust, which may lead to the fusion of oxygen, and the temperature will become very high, but the operation of the universe is relatively stable. It will not affect the normal life of human beings.

The earth will be destroyed, and all living things on the earth will perish, and the universe will be big**. Of course the Earth will be destroyed, because it is so fast that it is enough to destroy the Earth.

The earth may shake violently, cracks may appear in the ground, and various disasters may erupt, affecting human life. There is a possibility.

A needle hits the Earth at the speed of lightIt burns out in the atmosphere.

In fact, a sewing needle traveling at the speed of light cannot penetrate the thick atmosphere above the Earth. Without ignoring friction, the faster the velocity of the object, the more power the friction has to convert kinetic energy into heat energy per unit of time, so when the velocity reaches a certain value, the object burns. What's more, at such a fast speed of light, this little needle will burn out in the atmosphere.

Other inferences:

Since the needle is a small object, the energy generated by the impact of the object is closely related to the velocity and mass of the object. Therefore, we can roughly estimate the kinetic energy of this needle through the kinetic energy formula MV about 9 10 12J, if it hits the ground, these energies will cause a radius of about 4,000 meters **, which is equivalent to the energy generated by 10,000 tons of TNT**.

People in this range will die directly, and those who are farther away will also be burned by the heat wave generated by **. However, this claim is not credible because when an object approaches the speed of light, the kinetic energy theorem is no longer able to calculate its kinetic energy correctly.

<> what would happen if a needle hit the Earth at the speed of light? What will happen to the planet? The universe is infinite, so anything is possible.

There are many more similar questions, such as what happens if a drop of water hits the earth at the speed of light? Can a person move at the speed of light? If you start thinking about it, your braincase will hurt a lot, although at this stage you can only look at these problems as **.

Black holes in the universe actually exist, so when the earth is swallowed by black holes and turns into dark matter, how will the humble fate of human beings change? Don't say it's impossible, anything is possible! Because the universe is infinite, unimaginably big!

What will happen if a needle hits the Earth at the speed of light? It's an interesting question. Due to the size of the needle, the weight is too light, and the damage to the earth should not be too great.

However, here I would like to go to this question from another angle. If a needle really wants to hit the earth at the speed of light, it will be absolutely difficult to do so.

According to the principles of modern physics, when an object is moving at high speed, its energy is proportional to its speed, and the faster the speed, the greater the energy, and the speed of any object in the world has been wiped out if it reaches the speed of light. According to the theory of cosmic expansion, its expansion rate is always greater than the speed of light, therefore, everything in the universe is moving away from each other faster than the speed of light, and even if a needle flies towards the earth, it will never be able to hit the earth, but will be farther and farther away. Assuming the mass of the needle is one gram, its speed is 300,000 kilometers per second.

TNT explosives, ** speed per second. Energy is calculated in terms of the square of velocity. The energy contained in 1 gram of needle is equivalent to the energy of tons of TNT explosives.

After entering the atmosphere, the needle vaporizes due to the high temperature generated by friction with the air, producing **, which is equivalent to tons of TNT explosives in the air**. It has an impact within a radius of several kilometers, and as long as it is not a densely populated area, the impact on the ground and the earth is limited. As for the theory of relativity, at the speed of light, the mass of matter would be infinite.

Let's talk about it after we have the experimental data.

If a needle hits the earth at the speed of light, then the earth will be greatly hit, and even produce **, thus changing the appearance of the geology!

According to the theory of relativity, it is impossible for an object with mass to reach the speed of light, and the mass at the speed of light is zero, and not a needle, so this is not true.
