The speed of light can circle the earth’s equator seven and a half times in one second. Scientist: the speed of light in the universe is still too slow

As we all know, the speed of light is the maximum speed of objects in nature, 299792458 meters per second (about 300000 kilometers per second). At this time, do you think that the speed of light is very fast, and with the speed of light, you can start your space journey at will in the solar system.

The length of the earth’s equator is about 40000 kilometers, and the speed of light can circle the earth’s equator seven and a half times in one second.

If chang’e-4 flies to the back of the moon, it will take nearly a month to get there. But if the speed of light is toward the moon, it will only take about one to two seconds, because the distance between the earth and the moon is only 384400 km, which really shows that the speed of light is very fast.

The moon is about 384400 kilometers away from the earth. If it goes at the speed of light, it will take only 1.28 seconds to reach it. If you want to drive to the moon at 105 km / h without violating the speed limit, it will take 3700 hours, about 155 days.

Venus is the closest planet to the earth. The average distance between Venus and the earth is 40 million kilometers, which is equivalent to the length of 1000 circles around the earth. If Venus moves at the speed of light, it only takes 2 minutes and 12 seconds to reach. If it is on the other side of the sun, it will take about 15 minutes. If you still have to drive, this trip to Venus will take you nearly 400000 hours, about 44.5 years.

The shortest distance from Mars to the earth is about 56 million kilometers. If you go to Mars at the speed of light, you can get there in only three minutes. But if you drive at 105 kilometers per hour, it will take 540000 hours, which is more than 60 years.

Mercury is the smallest planet in the solar system. The average distance between mercury and the earth is 7700 km. It takes only five minutes to get there from the earth at the speed of light. It takes 740000 hours to drive, which is more than 85 years.

If you look at the sun, the distance between the earth and the sun is about 150 million kilometers. If you travel at the speed of light, you can reach the surface of the sun in more than eight minutes. It would take 1.5 million hours to drive. It’s a time we can’t afford.

So looking at the universe, if humans can achieve the speed of light, then the star trek in the solar system can arrive in just a few minutes. In the eyes of ordinary people, this is a very contented thing.

However, in the eyes of scientists, the speed of light is far from enough. They even think that the speed of light is too slow. The diameter of our solar system is about two light years. Even if we fly out of the solar system at the speed of light, it will take several years, let alone fly out of the Milky way and fly freely in the universe.

In 1998, when observing the universe, two scientific teams led by solpirmut and Brian Schmidt discovered that the universe expanded faster than the speed of light.

Therefore, it can be said that in fact, in the universe, there are spacetime moving faster than the speed of light, and they are not constrained by the speed of light.

By comparison, the speed of light is too slow, don’t you think? Welcome to comment area.
