Protons, electrons, and neutrons are formed. ]]> 2020-10-30 22:32:09 UTC https://padlet.com/1475532/mw9g8c74nhawczqz/wish/878026676 3 minutes 1475532 https://padlet.com/1475532/mw9g8c74nhawczqz/wish/878026900 The universe continues to expand, temperatures continue to cool, and 
Hydrogen (95%), helium (5%), lithium (trace amounts) form.

He concluded that since the light coming from other galaxies is redshifted, the other galaxies must be moving away from The Milky Way, therefore the universe had to be constantly expanding. ]]> 2020-10-30 22:37:30 UTC https://padlet.com/1475532/mw9g8c74nhawczqz/wish/878032959 Amount of Helium in Universe 1475532 https://padlet.com/1475532/mw9g8c74nhawczqz/wish/878034334 The fact that Helium is one of the most abundant elements on earth supports the idea of the BBT because Helium is claimed to be one of the first elements ever formed. The fact that Helium was one of the first main elements, and that it is still so abundant supports the BBT. ]]> 2020-10-30 22:38:42 UTC https://padlet.com/1475532/mw9g8c74nhawczqz/wish/878034334 Big Bang Theory 1475532 https://padlet.com/1475532/mw9g8c74nhawczqz/wish/878041032 The theory that the universe expanded and cooled, progressively developing into stars and galaxies.]]> 2020-10-30 22:45:16 UTC https://padlet.com/1475532/mw9g8c74nhawczqz/wish/878041032
