What Is Now, What Does It Mean?July 2, 2021
The time you are in. It is proved by the Einstein equations that there is no such thing as the same time that is called now. Because there is no such thing as absolute time in the universe independent of the matter-motion-space association. There is no static time interval in the universe that we can relate to it and say now. For example, we look at the star Arcturus in 1978, what we see is not the present Arcturus star, but the 1940 Arcturus star. Because the star Arcturus is thirty-eight light-years away from our world (A light-year, in other words, the distance that light travels in one year is 9.6 trillion kilometers. Radio waves are at the same speed). The rays that now show us the star Arcturus are those that departed from the star Arcturus thirty-eight years ago. So now we don’t even know if the star Arcturus is in place, we can only find out in 2016. Like the Arctururs star we see, we who see it are now (now) in a time, but that time is not now, i.e. the same time.
