According to this theory, the universe began in a super dense, super hot state and has been expanding and cooling ever since The phrase was coined by Fred Hoyle during a 1949 radio broadcast. ]]> 2017-06-20 16:14:44 UTC https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177003598 william001mackenzie https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177137491 From zero to 10-43 seconds (1 Planck Time). Fortunately, this is the closest that current physics can get to the absolute beginning of time, very little is known about this period in time. General relativity proposes a gravitational singularity before this time. ]]> 2017-06-21 20:44:38 UTC https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177137491 william001mackenzie https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177137997 As we move into the birth of our universe, cosmic inflation creates a quark-gluon plasma. At this time, protons and neutrons do not exist yet, only leptons and quarks, with their force carriers, gluons, W and Z bosons and photons. The quark soup exists because we have created similar conditions inside particle accelerators. It looks like this early quark soup gave that gave rise to dark matter. as an extra factor, the quark soup is likely the phase in which matter gained superiority over antimatter. Cosmologists speculate that the universe had equal amounts of each one, but at some point, it developed one extra quark, this is for every billion antiquarks. The imbalance ensured that enough matter survived annihilation as the universe expanded and cooled. ]]> 2017-06-21 20:54:47 UTC https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177137997 william001mackenzie https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177221692 Protons and Neutrons are formed from quarks. Within the first 300 seconds of the universe, the elements, helium, lithium and heavy hydrogen, deuterium and helium 3. They form from the protons and neutrons by a process called nucleosynthesis. Now Nucleosynthesis is the theory that accurately predicts the abundances of elements and isotopes measured in the primeval samples of the universe. Deuterium plays a special role in this process. It's measured value implies that ordinary amounts to 4.9 percent of the total energy density in the universe. The only energy left is dark energy and matter. This agrees with the data collected by Planck from the CMBR. The (CMB) image reveals the age, density, geometry, and the overall composition of the entire early universe. The image provides clear evidence supporting inflationary cosmology via the information that we can take from it. Quantum fluctuations causing temperature differences in this inflation field, on the subatomic scale get exponentially blown up to astrophysical sizes. 380,000 years when the nearly uniform soup cooled to about 3000 kelvin, atoms formed nuclei and electrons. photons scattered and streamed through space, unhindered, turning the prior opaque into one visible light. ]]> 2017-06-22 15:56:00 UTC https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177221692 william001mackenzie https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177223922 We then enter a period called the Dark Ages. We don't really know a whole lot about this period, unfortunately..... Except that the first stars and galaxies should have formed at about 100 million years. This is the limit of the current observations, that is, the highest redshift objects detectable. The oldest objects that we can see are at a time of when the universe was 600 million yeas old. 

Here is A Picture to Better understand!]]> 2017-06-22 16:20:23 UTC https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177223922 william001mackenzie https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177224759 2017-06-22 16:30:50 UTC https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177224759 william001mackenzie https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177225081 Dark energy, a weird, mysterious force that cosmologists have yet to wholly pin down, starts to accelerate. At 20billion years the Milky way will smash into the Andromeda galaxy, then our solar system, or at the very least, the inner planets, will, unfortunately, be gone by that time, due to the sun's rapid expansion that will come once it exhausts its supply of fuel for nuclear fusion.]]> 2017-06-22 16:34:55 UTC https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177225081 william001mackenzie https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177226339 Now the fate of the universe hinges on dark energy. If the universe continues to grow at about the same pace, this will result in all the last stars burning out in about 100 trillion years. (We Got A Bit Of Time Left). If this is true, 30 billion years all other galaxies are pulled from our view and all evidence of the big bang will be lost forever. Unless of course, we keep records, there are only a few methods anyway. Dark energy could also intensify, making a Big Rip. From atoms to superclusters, dark energy effectively tears everything apart. This would happen at Approximately 50 billion years. Dark energy could also slow down. This deceleration would give gravity the upper hand and lead to a collapse, DUH DUH DUHHHHH. At 30 billion years, we could have what is known as the big crunch. This would result in a new big bang from the cyclic universe scenario. ]]> 2017-06-22 16:50:50 UTC https://padlet.com/william001mackenzie/ysthgjjaj3pi/wish/177226339
