BIGBANG said that the universe is expanding. Why isn't the distance between the earth and the sun getting farther and farther?
This question is quite interesting. There are many phenomena among stars that cannot be explained by our current scientific level! For example, interstellar regression, quasars, superluminal phenomena, abnormal redshift, dark matter, dark energy and so on! At present, it is believed that the universe has not expanded! So the distance between galaxies and stellar systems is actually moving away from each other! Even our solar system is flying towards Wuxian at a speed of about 19.5 kilometers per second. Of course, this is only a directional goal. In fact, the solar system will never reach Wuxian, because the star of Wuxian itself is flying to its own directional target! The distance between stars is changing all the time, with relative expansion and relative contraction! Whether it is between the earth and the sun, or between the earth and the moon, it is actually getting farther and farther away! But why can't we feel and observe! The reason is very simple, because we are too small, the size of the universe is unimaginable, so suppose that even if the moon leaves us at the speed of 100 km per year, we can't observe it ourselves, and the separation speed of stars and galaxies can reach tens or even hundreds of kilometers per second! But we still can't observe it, because the distance is too far, and such changes must take tens of thousands or even millions of years to see! For example, the Big Dipper is so called because the constellation is shaped like a spoon! But100000 years ago was not like this, and100000 years later will become another way, because every persistence in the constellation is flying towards its own directional goal!
Just like the continental plate drifting, although it moves every year, you can't feel it!
