How do we know what we should be doing? We have to be able to see what’s coming down the pipeline, but how do we know what it is? It’s like the stars in the night sky, they often appear to be moving, but there is actually a good possibility that they are constantly in motion.
Astronomy actually has a long history of predictive astronomy. If you look in the sky there are certain patterns that you can see. If you look closely, you can see that they have certain types of motion.
Astronomers have long known that galaxies have super-fast, sub-relativistic motion. The galaxies’ motion is actually very close to that of sub-relativistic particles as well. This is called the General Relativity effect, and it was the reason that space travel was possible in the first place. Astronomers have discovered that that this effect actually has a significant effect on the structure of the universe. That’s why we see things moving faster than light.
In our universe the universe is only 13.7 billion years old, so the universe is still expanding. As this universe expands and cools, the particles that were initially moving at the relativistic speed of light start moving slower than the speed of light. This is called Hubble’s law. This means the farther away you are, the faster galaxies are moving. This is called the Hubble effect. The farther away you are, the slower galaxies are moving. This is called the Redshift effect.
This makes it easier to see the galaxies that are closer than you. And also makes it easier to detect the galaxies that are farther away than you. Also, as you get farther away from the Earth, the more stars you can see, the easier it is to distinguish between stars.
The more stars you can see, the easier it is to distinguish stars. And that’s why it’s important to go to the far-away galaxies, because they give you a better view of the stars. There just aren’t as many of them to begin with.
The star system is a tool that astronomers use to see galaxies. It is a method of measuring the distance to a galaxy. It works by using the stars in that galaxy as a standard to find out how far away from earth you are. It is similar to comparing the number of stars in a galaxy with the stars that are closer to earth. With a little computer help, astronomers can estimate how far away your galaxy is from earth based on the distance to the stars that are closer to earth.
We are talking about Hubble Space Telescope (HST) here. In the days when Hubble was the only tool astronomers had, it was used to measure the number of stars in a galaxy. When it was finally combined with the Hubble Space Telescope (HST) that we all now have, it is now called a “big telescope.” Hubble has a much larger field of view than HST and it is, therefore, able to find more distant galaxies than HST.
