If the universe would be static, the measure would be 0 kelvins because there would be no heat between objects.

The space that was between the Milky Way and galaxies was expanding sending the galaxies farther away from the Milky Way. ]]> 2020-10-16 05:51:44 UTC https://padlet.com/sd54/6l4sdwyrhhqqaslx/wish/834845218 shreym https://padlet.com/sd54/6l4sdwyrhhqqaslx/wish/834855500 2020-10-16 06:00:32 UTC https://padlet.com/sd54/6l4sdwyrhhqqaslx/wish/834855500 shreym https://padlet.com/sd54/6l4sdwyrhhqqaslx/wish/834857134 If there is a campfire, and there is 10 pounds of wood.

It was still very hot and dense though, so the cool down process had started and lasted for some time. Since it started to expand more it started to cool down as well. Then elements started to be created like protons, electrons and neutrons started to pop up. After that hydrogen was created with its one protons. Then thanks to the high energy and nuclear fusion, helium was created with 2 protons. And soon more kept getting created...]]> 2020-10-16 07:08:51 UTC https://padlet.com/sd54/6l4sdwyrhhqqaslx/wish/834929996 shreym https://padlet.com/sd54/6l4sdwyrhhqqaslx/wish/834959529 Soon the elements started to form, each on being created shortly after another.
