Best Answer

Hydrogen, helium, and a small amount of lithium.

If the BB is an accurate description of the early existence our Universe, then the ratio of hydrogen to helium to deuterium would be a certain value. The actual ratio matches the prediction of the BB quite well.

How long after the big bang did it take for stars to form?

the theory states that atoms formed during the big bang (like right as the big bang happened) Protons and neutrons were allowed to form about one second after the Big Bang. Electrons joined to nuclei to form permanent atomic bonds about 377,000 years later.


Which element in the universe was made after the big bang before any stars where made?

Scientists reckon that Hydrogen nuclei were the first to form (being the most simple element), around a few milliseconds after the `big bang`. Between 3 and 20 minutes they reckon that helium nuclei were the next to be formed. They then say that these nuclei were not able to capture electrons until around 379,000 years later.

How has earth evolved over the last 4.5 billion years ago?

No. Not much known during the Big Bang, but the big bang was 4.5 billion years ago, and it is today. Earth was formed once the big bang cooled down, and the big bang formed petrol in the ground because everything has been molten and formed petrol and got buried by the radiation when the bang cooled down and formed Earth.
