First of all, a light-speed spaceship can't be built, a sub-lightspeed spaceship close to the speed of light can。Second, if a sub-light ship were to crash into a grain of sand while flying in space, it would be entirely possible to scrap the ship or even destroy it completely, depending on how close the speed of the ship is to the speed of light. If the relative velocity of two objects is fast, when they collide, they will face a huge amount of kinetic energy.
Because of this, although space junk flying in space is small, they are extremely fast relative to some spacecraft and can cause serious damage in the event of a collision <>
So space junk poses a considerable threat to spacecraft。Similarly, if the spacecraft moves relative to the sand at an extremely high speed close to the speed of light, the sand will cause great damage to the spacecraft due to its extremely high relative speed, even if the sand is very small. The velocity continues to increase, and the kinetic energy increases further until the velocity approaches the speed of light and the kinetic energy tends to infinity.
Therefore, as long as the speed of the ship is fast enough relative to the sand, the sand can completely knock the ship to waste, or even destroy it completely.
It is also because the velocity tends to the speed of light and the kinetic energy tends to be infinite, as long as there is mass, no matter how small, its speed cannot reach the speed of light. Although space is very empty, due to the extremely high speed of sub-light spacecraft, it is necessary to consider the damage caused by the possibility of high-speed collisions with dust in space, so it is necessary to install a shield in front of the spacecraft that can clear obstacles.
This energy is equivalent to that of an atomic bomb (20,000 tons TNT)** dropped on Hiroshima that year. At a relative speed of light, the kinetic energy of the sand would be as high as 2 10 17 joules, an energy equivalent to that of a Tsar Bomba (a hydrogen bomb with a yield of 50 million tons of TNT)**.
-
The speed of light spacecraft is very fast, and encountering a grain of sand is like a plane landing on a bird.
-
Of course, it would be a disaster to encounter sand in the universe.
-
Yes, because even sand has a lot of momentum at the speed of light.
-
It should be, because they are very fast during the flight, and the danger brought to them by a grain of sand is also very large, so the consequences of scrapping are very likely to happen!
-
It's possible, even a grain of sand can be dangerous if it gets caught in important parts.
-
I think it will, even if it's too fast in a vacuum and the weight is still terrible.
-
Of course, even a small object can have a big impact at such a high speed.
-
If the speed is too fast, a grain of sand is like a big bullet.
-
This is very possible, because the spaceship is very fast and will be scrapped if the two collide.
-
A spaceship flying at the speed of light is strictly impossible to build. But what we're talking about is hypothetical, and in a hypothetical situation, from a scientific point of view, a spacecraft traveling at the speed of light hits a grain of sand, and the spacecraft will be scrapped. We all know that force is mutual, and if you fly at the speed of light, then what you hit will also travel at the speed of light.
A grain of sand is very light, but the amount it brings at the speed of light cannot be ignored.
1. The speed of light is the fastest speed known to mankind, and the speed of propagation in a vacuum can reach about 300,000 kilometers per second. In terms of human capabilities, it is not yet possible to build a vehicle that can reach 5% of the speed of light. And the closer a matter is to the speed of light, then it has an infinite mass, a mass that humans cannot control at present.
In other words, human beings today cannot build light-speed spaceships, or even spaceships that can be compared to the speed of light. However, human beings are developing rapidly, and maybe in the future, they will be able to control such a large mass and be able to build light-speed spaceships.
2. We all know that the plane will crash if it hits a bird during the flight. The reason is also very simple, not that the mass of the bird is and how destructive it is, but that the speed of the aircraft is too fast. When you hit a bird, the bird has the same speed as you, and the mass it carries increases countless times.
Although sand is infinitely lighter than a bird, the speed of light is infinitely faster than the speed of an airplane today. When a grain of sand rushes at you at the speed of light, it can easily penetrate your body, even a ship.
3. The interaction of forcesIn the physics books of junior high school, we learned a knowledge point called the interaction of forces. When an object exerts a force on another object, the object under force will in turn exert a force on the object. The spaceship hit the sand, which can also be understood as the sand crashing into the spaceship with a certain force.
-
Yes, because a collision between them would have a huge impact, which would have a serious impact on the ship.
-
Yes. Because when something moving at high speed collides, it will generate a lot of force, and it is very likely to be frustrated.
-
Yes. Because the ship is so fast, if it hits sand, it will be destroyed.
-
Yes. Because the velocity is relative, equivalent to sand hitting the ship at the speed of light, I think the ship will be scrapped.
-
If it does, it will be scrapped, but will there be a grain of sand in the universe? The mass of sand is so small, it will be captured by various passing stars in the universe full of gravity, and it is impossible to run into it, there may be asteroids in the universe, but I think the probability of the existence of sand is almost impossible.
If you want to think about scrapping, it's not a grain of sand, your ship will disintegrate long before it reaches the speed of light, and if you still have to accelerate to the speed of light, it will eventually disintegrate into a ball of light. At that time, if you touch another grain of sand, a little bit of your light will be absorbed by the sand, become a part of the sand, and let the temperature of the sand rise, and then release a little light energy; At the same time, some of the light that hits the sand will be reflected and continue to run at the speed of light in another direction until it hits another object and collapses into a material state.
It should depend on what material it is made of, and what happens when a hammer meets a stone of the same speed! The sun is still flying in the universe at the speed of light with the earth, and whether its protective circle is naturally formed or made by mysterious intelligent () aliens, when humans can build a spaceship with the speed of light, you can imagine how amazing its size and mass are. Not to mention the speed of light, the speed of an airplane is the speed of an airplane, and it is not okay to touch a grain of sand.
A ship flying at the speed of light and hitting a grain of sand is a grain of sand crashing into your ship at the speed of light. The faster the speed, the greater the energy, and a grain of sand flying at the speed of light hits the ship, absolutely piercing your ship, although the place where the sand enters the ship is only a hole the size of sand, and the place where it goes out, uh ......If you can't get out, you will rub against the air in the spaceship when you go in, and it will explode before you have time to burn. You should know what the speed of the meteorite entering the earth looks like, and the energy of the impact at the speed of light is probably clear.
However, the speed of light flight thing has to be solved by humans first before it can be realized!
-
It's a big impact, because the speed of this spaceship is very fast, and if it encounters a grain of sand, it will have a lot of impact, which may cause this thing to be paralyzed.
-
The impact is really very large, it may directly cause a spacecraft crash, you can't touch anything when you are flying in space, and you must ensure that the ride is smooth.
-
The impact must still be very large, because the speed is too high, so if you hit it in such a situation, it is likely to cause a lot of damage.

The speed of light, as the name suggests, refers to the speed at which light travels through the universe, about 300,000 kilometers per second. At the moment, the fastest fighter has only the speed of sound (1231 kilometers per hour), intercontinental cruise missiles are expected to reach the speed of sound (20 kilometers per hour), the launch vehicle of the first cosmic speed (getting rid of gravity) is kilometers per second, and the second cosmic speed (getting rid of the solar system) is kilometers per second. The third universe has a speed of kilometers and can travel in space.
The newest black hole in the Milky Way galaxy spins at times the speed of light, making it the fastest object in the universe.
If the current scientific theories of mankind were analyzed, it would be impossible for mankind to build an airplane synchronized with the speed of light. Even if we theoretically break the limit of developing light-speed aircraft, it is impossible to break through the material science and technology of building light-speed aircraft. Now, let's assume that humans are perfectly capable of building light-speed ships.
However, from the analysis of the black hole's velocity, it was found that the matter around the black hole (including light) was swallowed by the black hole at the speed of light. What would happen if the speed of light made by humans flew that high into space? When the spacecraft reaches the speed of light, will it act like a black hole, sucking everything around it?
Is it possible that the effect of the speed of light will be neutralized both technically and in its materials?
In order to survive better, human beings continue to explore the universe, and the desire is good, but it cannot go beyond the boundaries of the laws of nature. When the spacecraft really enters the sand at its speed during the flight, the consequences can be imagined, just like an airplane hitting a bird, and the speed of the airplane is only kilometers per second (calculated by two sounds), compared with the speed of light of 300,000 kilometers per second, the result of the spacecraft entering the sand must be the ship's destruction, death, flying ashes, and thick smoke. Even if there is no wind and sand, when the spacecraft flies in space, the heart, molecules, atoms, electrons, nuclei, quantum, etc. in space produce high-intensity friction with dark matter, which is <>
A change in mass density caused by the pressure of high-speed flight occurs by raising the surrounding temperature to jointly cause nuclear fission**, the result of which is unimaginable. If there really comes a day, when all the above-mentioned human nature is finally broken, it is not known that a spacecraft that can fight against sand will become the speed of light, but I know that according to the current understanding of the nature of science and technology, it is impossible for humans to make a spacecraft reach the speed of light, let alone a controllable speed that can resist the impact of sand. The meaning and reason of the investigation are better, let the experts judge!
-
Scrapping may occur. Because the speed of the spacecraft traveling at this speed is very fast, if it is touched by any foreign object, it may cause the mass and the direction of travel of the spacecraft to change and close, so it may lead to a collision with the ship, which will lead to scrapping.
-
Will be celebrity. This is because the sub-light speed of the ship is very fast, so it is likely to have a serious impact after hitting a grain of sand, and it is likely that the base will be scrapped.
-
It will be scrapped, because the speed of the sub-light speed spaceship is very fast, and the energy will be very large when it encounters a piece of sand, so it will be scrapped directly.
-
If the spacecraft encounters a grain of sand while flying, will the spacecraft be scrapped directly? Why? At the physical level, there is no object beyond the speed of light, and there is no such thing as a speed-of-light spaceship, so the question is not valid!
Maybe the "space jumping ship" or "space folding spaceship" is closer to the concept of the spaceship you mentioned, but when jumping faster than the speed of light, the ship itself is likely to move at the same speed as a normal vehicle, or even slower or stop moving! Therefore, it is not afraid of obstacles when moving faster than the speed of light, and any object that can fly at high altitude at high speed is certainly unlikely to collide with something as small as a grain of sand, why? As long as you understand the principle of the bicycle pump, you can understand the reason for the over-hitting.
Any forward motion of an object inevitably compresses the air in front of the object. The compressed air is like a stream of air that sounds in front of the object.
Don't say it's a grain of sand, even if it's a bunch of sand, the spacecraft has been blown away before it arrives. Or think back to riding the subway: you have to feel like the wind is coming before the train arrives.
In the past, it was still a question like this, what happens if an egg hits the earth at the speed of light? Since there is no object that has reached the speed of light, all Noriga can be played at will without exception and irrefutable. The vast majority of people worship the speed of light, saying that the energy of an egg flying at the speed of light is very huge, not to mention the earth, the sun can destroy it.
Now the question is just a change of direction. It's a huge light-speed object hitting a small object, not a small light-speed object crashing into a huge object. If according to the theory of the enormity of the speed of light, a small egg can destroy the earth at the speed of light, then how can a large and huge light-speed spaceship destroy a small grain of sand?
Isn't that a paradox?
For example, if an egg hits the earth at the speed of light, and the earth hits the egg at the speed of light, do you say that the egg breaks at a large rate or the earth breaks at a large rate? It's like I slap a mosquito with the palm of my hand, is the mosquito broken or the palm broken? It's not a question of who is bigger or smaller, but how much energy is formed if the speed of light is reached and how much damage is caused on impact.
So we can calculate, let's say milligrams of sand. Kinetic energy formula: What is the energy of the 9th power (joules) of ek=mv*2?
It's enough to destroy the ship and the sand, right? However, if there is a baffle that is harder than the sand one centimeter in front of the spaceship, which just blocks the first collision with the sand Chong Sui, the sand will immediately fly away, with zero speed and zero momentum, and the damage to the spacecraft will be zero. It's like an airplane hitting a bird.
With only one layer of impact, the bird will not pass through the body of the aircraft and injure passengers, because if the body is the first impact, the bird will slow down, the kinetic energy will be reduced, and the damage will be small.
unimaginable. Probably, "the lights at that time were faster-than-light lights". >>>More
Since the expansion of the universe is mentioned, another idea must be involved, whether the universe is finite. If the universe is finite, it can't be far enough. In fact, at a distance of enough distance, the mathematical model of the universe is used to simulate it has always been an undecided question. >>>More
I think there must be speeds faster than the speed of light in the universe. Because in Einstein's theory of relativity, it is said that time travel can be achieved by exceeding the speed of light. This is also a disguised proof that it is achievable to exceed the speed of light, but now we cannot prove it with practice. >>>More
Yes, what the book says is true. Even our current aerospace technology needs to use the theory of relativity, otherwise, due to the effect of speed on time, we will not even be able to calibrate the time on the spacecraft.
The speed of light is not superimposable, that is, the speed of light is constant, which is a basic postulate of Einstein's special theory of relativity. It means that in a vacuum, the speed of light is about 300,000 kilometers per second, which is always constant, independent of the speed of the luminaire, the speed of the measurer, or the speed of the device that measures the speed of light. At the same time, this also shows that in the universe, there is a maximum speed of information transmission, which is the speed of light, and when any object transmits information, no matter what method is used, the speed of transmitting information cannot be greater than the speed of light, it is a limit speed. >>>More
