Eliza Revell Big Bang Theory Task-Science 2015 10CH
For a very long time the Big Bang theory has been one of the most talked about topics in science.
Most astronomers believe that the universe began with a ' Big Bang '
They believed that it happened about 14 billion years ago. At that point in time, astronomers think that the universe was inside a dense kind of 'bubble' that was thousands of times smaller than a pinhead. They think it was extremely hot and denser than anything we could possibly imagine.
Then all of a sudden it exploded.
At that point in time we believe that the universe was born.
Space, time and matter all began with a ' bang '. In less than a second, the universe grew from something smaller than an atom, and has increased to the size it is today. In fact it is still expanding today!
Over 3-4 minutes the temperature dropped below 1 billion degrees Celsius. This meant it was cool enough for the protons and neutrons to come together to form hydrogen and helium nucleus. Finally, after 3 hundred thousand years, the …show more content…
This blue light is a sign that very young, massive stars are forming. Because we see these galaxies as they were between five and ten billion years ago, we appear to be witnessing events that occurred within a few billion years after these galaxies were formed. Astronomers have also noticed that by examining the images of these distant blue galaxies, the images are frequently distorted or contain what appear to be multiple nuclei. The Milky Way, which is seen at a similar great distance would look like a uniformed flattered disk, with a single bright nucleus. But in at least some instances, such as NGC1275, recently observed with the Hubble Space Telescope, galaxy collisions can actually start to trigger the formations of massive
