The speed of light is 300,000 kilometers per second. Is there a camera that can capture its speed?

In a sense, people have got the speed of light, so they can only say that they have it. It is possible to get in touch with the secret of time, but this is only a possibility, because we only know that there is such an observation in front of us now. Without breaking through this observation, we can't explore the world ahead, but it doesn't mean that we can reach our destination if we break through this barrier. No one can say for sure.

Not let your body reach the attack speed, but let your consciousness carrier reach the speed of light. Theoretically, human consciousness should have no quality. Because your mind is a blur, although it exists in the brain, it should have no quality. When it can develop to a certain extent in the future, people's consciousness may exist in a special way out of the body. At that time, it may reach or even exceed the speed of light, and we will touch the 1 threshold for exploring time and space.

The reason why we say this is that, first of all, we must understand that the earth itself does not emit light. The reason why the earth shines is mainly because of the sun's irradiation. We can observe that the earth is a luminous blue planet in outer space, mainly because our atmosphere scatters sunlight. It can be said that the earth we see is just a scene formed after being scattered by the atmosphere. Of course, we can also directly observe some signs of human activities on our ground through some remote sensing satellites, but there are still some errors in these signs.

In addition, the earth itself is not a luminous body, so its light source is unstable and the light is weak. So if we observe the earth from 1000 light years away, we may not be able to observe or even let us observe the sunlight. As I said before, light will be affected by all kinds of radiation during its propagation, so even if we reach 1000 light years away, the light on the earth can be observed by us, but the influence of this radiation is always there.

Nowadays, some scientists have doubts that the fastest speed in the universe is the speed of light. They have been trying to find new evidence to overthrow the existence of faster than the speed of light. In fact, as early as around the 1920s, American scientist Edwin Hubble put forward the theory of Hubble's Law. When he was observing galaxies before, he found that many galaxies were leaving us, and the farther the distance, the faster the information. This phenomenon is generally believed by scientists that the universe is expanding. According to scientists' research, the universe has expanded by 65.438+038 billion light years, and its diameter has exceeded 92 billion light years, and it is still expanding! For this phenomenon, dark matter and dark energy are great contributors to the expansion of the universe! ?
