It basically states that before the universe was the way we knew it, it was an infinitely small singularity, which was also infinitely dense and infinite in temperature. However, a phenomenon known as the big bang caused this singularity to expand rapidly, and this singularity was then known as a universe. In fact, according to this theory, the universe still and will be expanding until the end of time (or until the Big Crunch happens but that's a different story).]]> 2021-09-03 14:39:07 UTC https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1715395553 luisacuna4 https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1715450287 The theory was first acknowledged as an official scientific theory in 1931, however Lemaître had started developing the theory before 1927. He published his theory in a scientific paper in 1927 in a foreign language, however, which may have contributed to the lack of attention it got. In 1930, he told Arthur Eddington about his theory and Eddington was so astounded by Lemaître's findings that he immediately notified fellow cosmologists of Lemaître's paper and he and a group of cosmologists called for the publication of Lemaître's paper in english.]]> 2021-09-03 15:03:58 UTC https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1715450287 luisacuna4 https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1715487439 https://www.space.com/25126-big-bang-theory.html

One of the big pieces of evidence to support this theory is a type of radiation called cosmic microwave background (also known as relic radiation or cosmic background radiation) which is a supposed remnant of the big bang event. See, CMB was present around 400,000 years after the big bang event, in which the universe was one hundred-millionth of its size now, and it's temperature was 273 million K. It was so hot that any atom would immediately be broken down into small particles such as electrons and protons. The radiation from the CMB was scattered off electrons but were unaffected by the changes of temperature over time and remained intact through present time. However, the CMB has cooled so much that these rays are only 2.725 K above absolute zero. Because of their sheer temperature, they are most visible when put through the microwave section of the the light spectra (a.k.a. the electromagnetic spectrum). These historical rays are relics of the past, which very well may be the key to unlocking knowledge and confirming the existence of the Big Bang.]]> 2021-09-03 15:46:40 UTC https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1715562684 luisacuna4 https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1716009704 This question is a bit tricky, so let me try to my best to dissect and explain it (because I can't find much on google). Let's start with size. If something is described as infinitely small, it means it is smaller than anything, it is smaller than the concept of measurement itself. For the universe to be infinitely small my only guess would be that it was insanely dense, like, much, much denser than a neutron star. Eventually this mass might have collapsed under its own weight since its matter might have been so compact that it would ignore the boundaries of other matter near it. This means all of the matter of this extremely dense object wasn't technically fusing (at the moment), but the matter instead sort of overlapped each other, meaning all of this matter would now have the same exact location in space-time, but would be separate things (and the matter I'm referring to is everything that something is made up of, meaning all atoms, electrons, neutrons, quarks). But, since half a quark is still considered matter, I believe infinitely small size-equal pieces of matter would be broken off, and the matter that would be overlapping each other would be these infinitely small pieces of matter. Since these pieces were somehow located in the same exact location in space-time, the size of these pieces would also be the size of this pre-Big Bang universe. This also solves the dense question, because if something is infinitely small, then it would also have to be infinitely dense. As for temperature, I believe that initially this premature universe was at 0 K, since if it was anything above absolute zero, then the matter would move, causing it to spread, which, according to my theory, can't be possible. However, I do believe that temperature was the trigger for the big bang. Let me explain. Hydrogen atoms were present in this premature universe, and when these infinitely small pieces of hydrogen sort of overlapped one another, they underwent nuclear fusion and it sort of used up most (most of infinity is still infinity) of these pieces of hydrogen, skyrocketing the temperature of the singularity from 0 K to ∞ K. And because matter starts to vibrate and move when its temperature is higher, this infinite amount of heat made all of the matter in this singularity start moving, causing the singularity itself to expand (sort of like what happens in a star). And this event of expansion in this singularity was known as the Big Bang.]]> 2021-09-03 20:18:20 UTC https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1716009704 luisacuna4 https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1719580938 I believe there are two scenarios (they're pretty simple, don't worry) that might have occurred that will explain why hydrogen still exists. Scenario #1: the infinite pieces of hydrogen wasn't all used up. Since nuclear fusion doesn't take the exact same amount of time for each occurrence, some hydrogen fragments, right before they were about to undergo nuclear fusion, were blown away by the infinite explosion, causing some of them to sort of weld back together into hydrogen atoms (well, when the universe cooled down enough), since the infinite pressure acting on them was not there anymore. Scenario #2: Hydrogen was fused back into existence. I don't like this one, because it's boring, but it's possible.]]> 2021-09-06 15:20:44 UTC https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1719580938 luisacuna4 https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1719602186 The heat coming from the infinite nuclear fusions isn't as prevalent anymore and is definitely not infinite... where we are. I'll get to it later. While I can't disprove or explain the theory that the universe is expanding faster, I can explain why it might be expanding at a constant rate. This takes us back to the prevalence of the infinite heat of these infinite nuclear fusions. From where we are right now, the ratio of hydrogen to helium is 3:1, or 75% hydrogen and 25% helium. And I believe it remains this way for pretty much the entire expanding universe, except for the outer edges. You see, an infinite amount of heat can't just fade away. It's infinite, it can't logically fade. So I believe that the outer edges of the universe are still infinite in temperature, which explains why it is still expanding, and why it is going to keep expanding until the universe has run out of matter. According to my guess, this means that we will probably never be able to get even remotely close to the edge of the universe since it would be infinitely hot, it would be brighter than anything in the universe, and since energy coming from nuclear fusion is released as electromagnetic radiation, it would horribly deform and disorient you before quickly vaporizing you from existence. As for how the center temperature of the universe isn't infinite when the outer edges are, I have no idea (yes, I admit, this theory has holes in it).]]> 2021-09-06 15:31:15 UTC https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1719602186 luisacuna4 https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1719632761 https://www.space.com/24073-how-big-is-the-universe.html

Red shifts is the tendency of waves to shift towards the red part of the light spectra when an object is moving away from you. For example, when looking at a galaxy that is moving away from you, the wavelength of the light coming from the galaxy would be shifting towards the red part of the light spectra. With this, astrologers have concluded that far away galaxies are moving away from us, supporting the statement that the universe is expanding, which is an idea of the Big Bang.]]> 2021-09-06 16:29:06 UTC https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1719695961 luisacuna4 https://padlet.com/luisacuna4/jbf9aeaben0rcvuc/wish/1719716636 https://www.energy.gov/science/doe-explainsnuclear-fusion-reactions
