Detailed explanation-1: -The data indicates that hydrogen and helium make up nearly all of the nuclear matter in the universe. The most abundant element, hydrogen, accounts for 74% of the mass while helium contributes 25%. Heavier elements comprise less than 1% of the total.
Detailed explanation-2: -Over 80% of all matter in the universe is made up of material scientists have never seen. It’s called dark matter and we only assume it exists because without it, the behaviour of stars, planets and galaxies simply wouldn’t make sense.
Detailed explanation-3: -They’ve found that the universe contains about 74 percent hydrogen and 26 percent helium by mass, the two lightest elements. All the other heavier elements–including elements common on earth, such as carbon and oxygen–make up just a tiny trace of all matter.
