THE BIG BANG by Rosanna Saprio https://padlet.com/r_saprio1/bigbang CLIL en-us 2018-10-09 09:06:37 UTC 2025-12-08 13:06:24 UTC hello@padlet.com The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today. r_saprio1 https://padlet.com/r_saprio1/bigbang/wish/290621151 In 1927, an astronomer named Georges Lemaître had a big idea. He said that a very long time ago, the universe started as just a single point. He said the universe stretched and expanded to get as big as it is now, and that it could keep on stretching.

And that’s not all. The farthest galaxies were moving faster than the ones close to us .When the universe began, it was just hot, tiny particles mixed with light and energy. It was nothing like what we see now. As everything expanded and took up more space, it cooled down.The tiny particles grouped together. They formed atoms. Then those atoms grouped together. Over lots of time, atoms came together to form stars and galaxies.The first stars created bigger atoms and groups of atoms called molecules. That led to more stars being born. At the same time, galaxies were crashing and grouping together. As new stars were being born and dying, then things like asteroids, comets, planets, and black holes formed! r_saprio1 https://padlet.com/r_saprio1/bigbang/wish/290621662 2018-10-09 09:15:34 UTC https://padlet.com/r_saprio1/bigbang/wish/290621662 Big Bang Theory - Common Misconceptions There are many misconceptions surrounding the Big Bang theory. For example, we tend to imagine a giant explosion. Experts however say that there was no explosion; there was (and continues to be) an expansion. r_saprio1 https://padlet.com/r_saprio1/bigbang/wish/290624506 2018-10-09 09:24:38 UTC https://padlet.com/r_saprio1/bigbang/wish/290624506 ok santysemillitasyt https://padlet.com/r_saprio1/bigbang/wish/1760391979 10/10]]> 2021-09-22 15:23:12 UTC https://padlet.com/r_saprio1/bigbang/wish/1760391979
