Suppose you return to Earth after flying at the speed of light for ten seconds, are your loved ones

It's gone. Because time stands still when traveling at the speed of light, let's say you travel at the speed of light for ten seconds and then return to Earth, many years have passed on Earth, so your loved ones at home are no longer there.

If you are gone, your family will worry about you, and they may have died of depression long ago.

The loved ones at home are still there, and the time on Earth will not change much, maybe just one day has passed on Earth.

If a person flies at the speed of light for 10 seconds and then returns to Earth, will he still be able to see his family?

Why is it said that if you travel a few minutes at the speed of light and then return to Earth, then the Earth will pass for decades?

When an object reaches the speed of light, the concept of time does not exist, because the energy required to reach the speed of light is astronomical, and this energy is unimaginable. But if we answer this question from the dimension of distance, we may be able to calculate how many years have passed.

First of all, we know that the speed of light is 300 million meters per second, so according to three minutes, it is 180 seconds, and the distance traveled by the speed of light in three minutes is 50 billion meters.

The next thing we have to think about is, how is the earth time calculated, one rotation of the earth is one day, and the rotation of 365 revolutions is one year, so what is the converted distance? Then we need to know the circumference and rotation speed of the earth, different dimensions have different circumferences, and they are also different rotation speeds, so we choose the maximum value is that the circumference of the equator is 40 million meters, and the equator will travel so much distance in a day, so how much distance does it travel in a year? The distance of the equator in one year = the distance of the Earth's equator is 14.6 billion meters.

Knowing the above two data, the distance of three minutes at the speed of light is known, the distance traveled by the Earth's equator in a year is known, and the distance at the speed of light of three minutes divided by the distance traveled by the Earth's equator in a year is equal to the year, that is, it is equivalent to 4 years.

Everyone must be very strange, so different dimensions, there will be different times? That's true, because if we compare it to the equator, then it's equivalent to the speed of light in three minutes at the equator, i.e., four years after the Earth, and different dimensions will have different results, which is calculated relative to motion.

So when the speed of light is reached, the concept of time does not exist, and these three minutes may be years, or decades, or centuries, or even hundreds of millions of years. It's a very abstract concept that will make you feel incredible, but that's exactly what it turns out to be.

This is relative to the Earth, that is, after a few years and decades, if it is relative to the spacecraft that reaches the speed of light, different references have different results, and they are all relative results.

First of all, the speed of light cannot be reached, never will, just as 1+1 cannot be equal to 3. Second, assuming that people travel at close to the speed of light, time is close to static. He traveled to space for decades, and for him it was only a few hours, and humans on Earth were decades.

Because light can travel at high speed in the universe, the distance of the earth is very long, and even the speed of light takes a long time, so it will be decades after returning to the earth.

Mainly because there is now a theory that the flow of time at the speed of light is not the same as the flow of ordinary time.
