If a man is in a spaceship flying at the speed of light, flying at the speed of light,
If human beings have invented light speed flight, they will naturally solve the problem of survival on spaceships. Of course, this can not be achieved now because "objects have mass, so they can't move at the speed of light. According to Einstein's famous program, as they move faster and faster, the mass of objects will continue to increase. As they move closer to the speed of light, the mass of objects will become infinite, When a dust flies at the speed of light, it will have infinite mass. At this moment, it needs infinite energy to make the dust move at a speed close to the speed of light
How far is the earth from the moon? How long does it take to fly?
The average distance between the earth and the moon is 384400 km. The distance between the moon and the earth's perigee is 357000 km. The farthest distance between the moon and the earth's apogee is 406000 km
How long does it take for the earth to get to the moon?
The distance between the earth and the moon is 384000 km
It takes about 1.28 seconds for light to reach the moon
Apollo 1 took 75 hours and 50 minutes to fly from the earth to the moon

- 1. How long does it take to get to the moon from the earth
- 2. The mass of the earth is 81 times that of the moon, and spaceships fly from the earth to the moon The distance between the moon and the earth is 3.84 times 10 to the eighth square meter. It is known that the mass of the earth is about 81 times that of the moon. The spacecraft is attracted by the gravity of the earth and the moon on the way to the moon. When it arrives at a certain area, the resultant force of gravity is equal to zero. How far is this area from the earth

- 11. How to understand that a year spent in a spaceship traveling at the speed of light is equivalent to a million years on earth? For example, there should be no reference to time, it is absolute. For example, my watch in the spaceship will walk slower, the same watch, the pointer speed is the same, how can it be placed on the spaceship to walk one circle time, the earth will walk ten circles
- 12. Why does it slow down near the speed of light
- 13. Is it right that the speed is close to the speed of light and time slows down or stops? Time is just a concept. It is a unit of measurement of the regular change of matter. For example, year, year, and day. I don't understand that if we move at or near the speed of light, time will slow down or stop. The original meaning is: can the speed of light slow down the change of matter? What kind of trajectory is needed to produce such an effect? Is it linear motion or circular motion or rotation? Personal feeling: suppose there are two children just born when the speed of light train starts, one is on the train and the other is at the departure station. After 20 or 30 years, their life change characteristics should be the same (in short, the aging degree is the same), If the train returns to the departure station at the speed of light 20 years later, is it a meeting between two young people, or a meeting between a young man (on the platform) and a baby (on the train), The minute of a stationary person is infinitely lengthened in his life cycle). If it is the period of material change that slows down, will people on the train with the speed of light feel that their life has changed a lot? (the train has been running for 1000 years, but they have not changed at all)
