When Was Hubble's Law Created

The Big Bang is the most widely accepted theory about how our universe first began. This theory was first proposed by Belgian priest Georges Lemaître in the 1920’s. It suggests the universe was once condensed into a space equivalent to less than a grain of sand and expanded to billions of kilometers wide in about a second producing incredible amounts of heat. Everything you see is from that rapid expansion. That’s difficult to imagine, however, 3 major pieces of evidence support this; Hubble’s Law, Cosmic Microwave Background Information, and Big Bang Nucleosynthesis.
The first piece of evidence, Hubble’s Law, is named after Edwin Hubble, who first wrote about it in 1929. Hubble’s Law is primarily about how speed and time are related, and also …show more content…
George Gamow first developed this theory with his student Ralph Alpher in 1963. As I mentioned before, it’s theorized that after the Big Bang cooled down a bit, protons and neutrons began to fuse together, and fused with electrons. Neutrons decay in about ten minutes, so within that time there was a set amount of elements created, including hydrogen, helium, and lithium. When astronomers measure the ratios of these elements, they match up with the perspective of the universe once being a ginormous star. 24% of ordinary elements are helium made at that time during the Big Bang.
Thanks to the contributions of astronomers, we can understand our universe better than ever before.We still have much to learn, but there’s no doubt, with as much evidence as there is it’s simple to understand why the Big Bang is the beginning of the universe. First, there’s Hubble’s Law, which shows that the universe is expanding and started at one point. Next, there’s C.M.B.R. which gives us actual radiation we can detect from the event itself. And finally, there is Nucleosynthesis, which gives us insight into what happened and also the makeup of the
