The Mystery of the Universe takes you through

Living in this universe, we can only see the sun set in the east and west every day, and we can only feel that the world is too big to explore. Our ancestors began to think that this was a place where the sky was round. To this day, with the launch of the spacecraft, our team's understanding of the universe continues to deepen, but there are still many problems in the universe that are difficult to figure out. Does such a large universe have life besides earth? There should be some. Aliens are a kind of life that we are familiar with and unfamiliar, mainly because they have never confronted people directly and do not know how they came to Earth.

Today, I boldly conceive of writing an alien biography. According to scientists, the furthest distance from Earth is 2.6 billion light-years. As for how far these 2.6 billion light-years are, I can only say that my knowledge can only say that it is an astronomical number, for the simple reason. This is the answer of the astronomers. Of course, that's an astronomical number, isn't it? Unbelief counts. As for the result, it's certainly a long number. You can calculate that the speed of light is 1 speed of light = 299792458 m/s, multiplied by 60 seconds, multiplied by 60 minutes, multiplied by 24 hours, then multiplied by the result by 365 days, and finally multiplied by 2.6 billion years. I don't know if you can read this number. If you could read it, you wouldn't call it astronomical. Still, I'd like to give a simple example of what 2.6 billion light-years is. It's actually quite simple. That is, if the universe, the furthest from Earth, disappears, we won't be able to see its light until 2.6 billion years later to know it's gone. This shows how big the universe is. But now that science is well developed, there are still many things that cannot be explained. Later, many doubted whether these great achievements had the participation of external forces. It should be, otherwise how can it not be explained?
