Activity 3: Big bang, the origin and the expansion of the Universe

´-Universe origin (big bang):

There was a small bubble but very dense and hot that suddenly exploded and formed the universe. Matter and antimatter were created which destroyed each other but fortunately something survived and became protons and neutrons. Thousands years later electrons joined protons and neutrons and they became atoms.

After 300.000, the universe had cooled about 3.000 degrees and it filled with clouds of hydrogen and helium gas.
Now the universe is still expanding evently and its impasible dificult to calculate his size.
