Those who are looking for an answer to the question «Judging from the abundance of stars in the universe where does most of the hydrogen and helium come from?» often ask the following questions:

♻️ Where does most of the hydrogen and helium come from in the universe?

Helium (chemical symbol He) is the second most common element in the universe, the most common being Hydrogen. It is important in astronomy, as it is both a product and fuel burnt within stars, and in cosmology, as primeval helium was formed in the first few seconds after the Big Bang.

♻️ Where does the universe come from?

The probability for an object to materialize decreases dramatically with the mass and complexity of the object. In 1973, Edward Tyron proposed that the Universe is a result of a vacuum fluctuation. The main difficulty of this proposal is that the probability that a 13.7 billion year old Universe could arise from this mechanism is extremely small.

♻️ Where does most of the stars in the universe?

Neutron stars pack one-and-a-half times the mass of the sun into a ball only 10 miles across. A teaspoon of material from their surface would weigh 10 million tons. Many stars in the universe are...

The fact that helium is nowhere seen to have an abundance below 23% mass is very strong evidence that the Universe went through an early hot phase. This is one of the corner-stones of the Hot Big Bang model. Further support

But here on Earth, hydrogen and helium are only a small part of the world we inhabit. By mass, hydrogen and helium combined make up far less than 1% of the Earth, and even if we restrict ourselves...

These atmospheres are composed primarily (85–95% by volume) of molecular hydrogen (H 2) and helium (He) (5–15%) with smaller amounts of compounds of carbon, nitrogen, and oxygen, primarily present in the form of saturated

[/caption] Helium is the second lightest element in the known universe. It is also the second most abundant. According to some estimates helium accounts for as much as 24 percent of the Universe ...

Such differences of the He abundance may lead to a significant effect on spectral lines. For late-type stars, helium does not contribute to opacity and free electrons, but it affects the mean molecular weight and hence the electronii

Looking around the Universe today, there’s no doubt that there’s plenty of hydrogen and helium around; after all, it’s the nuclear fusion of hydrogen into helium that powers the vast majority of

Most of the other, heavier elements are created in nuclear reactions that go on in the enormously hot cores of stars (stellar nucleosynthesis). But a handful of elements arise from neither process. Boron, as well as beryllium and some varieties of lithium, are not made in the big bang, nor are they made in stars.

Abstract. Hydrogen and helium are the two most abundant elements in the Universe. As a matter of fact, the entire cosmic inventory of hydrogen and helium make up over 98 % of all known matter in the Universe. The remaining 2 % amounts to every other element combined. Despite the fact that our Earth is a rocky planet and contains an abundance of ...

The abundance of chemical elements in the universe is dominated by the large amounts of hydrogen and helium which were produced in the Big Bang. Remaining elements, making up only about 2% of the universe, were largely produced by supernovae and certain red giant stars .

Can hydrogen and helium conduct electricity?

A hydrogen nucleus is simply a proton. A helium nucleus is two protons and two neutrons. We can make helium by fusing together 4 hydrogen atoms. But look: 4 x M(hydrogen) - M(helium) = 26.71 MeV. Compare this to what happened when we ionized hydrogen: The energy difference is MeVs, not eVs. Much bigger.
