The Big Bang:


 Today I am going to be talking about the Big Bang theory. The beginning of the universe and itself.


 Around 14 billion years ago the universe began.Everything is created by the matter matter created in the first fractions of a second of the big bang. According to the research of Stephen Hawking's, the universe began a s a singularity and therefore It was extremely dense, very small and incredibly hot. This is known as the Big Bang theory. A few fractions of a second after this initial beginning protons, neutrons and electrons started to form causing the expansion of space itself.  Before even a second had passed it went from being smaller than an electron itself to nearly the size of the universe today.
The big bang would have been blinding. it would have emitted a huge amount of light due to the density and heat being produced.


 Scientists believe that the big bang did happen, if so then we know that the universe began through a rapid degree of expansion. If the universe started at a state of expansion then we can conclude that space itself must be continuing to expand and so its physical geography is constantly changing. The astronomer Edwin Hobol proved this through observations at mount Wilson observatory in Los Angeles, in 1929.

The fourth dimension:  The universe is physically a three dimensional space, consisting of length, width and height. the fourth dimension is time. Everything must have a beginning in order to exist. therefore everything must also come to an end. The universe began with the big bang, this means that the universe has a beginning and so must have an ending.  When the three physical dimensions and time come together to form the fourth dimension known as space-time. The blend of the dimensions into one is known as a continuum.         https://whyfiles.org/ When space-time is empty it is flat, it has no curvature. When mass is applied to or in space it causes the space-time to curve. space-time is s flat surface and is therefore mouldable to the the shape and density of the mass applied to the space.  Now that we know how space initially began and that we know that our universe has a beginning and therefore has an ending. Now we can begin to...

 How did the planets and the stars form? Stars and planets form within dense clouds of dust and gas known as nebula. http://2.bp.blogspot.com/   The formation happens in the nebula. Gravity forces the dust and gas to bounce at high speeds into each other. This causes molecules of gas to fuse together through nuclear fusion thus creating hydrogen gas. The hydrogen then creates helium, then carbon, oxygen, calcium and iron. The energy released when the gases fuses generates heat.
