Where did the primordial atom come from?

As the universe continued to expand and cool, things began to happen more slowly. It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms. These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe.

What is primeval atom?

The primeval atom hypothesis is a cosmogonic hypothesis which pictures the present universe as the result of the radioactive disintegration of an atom.

Where did the original energy in the universe come from?

But at the birth of the Universe – that is, everything – the energy needed for the Big Bang must have come from somewhere. Many cosmologists think its origin lies in so-called quantum uncertainty, which is known to allow energy to emerge literally from nowhere.

Where did the mass of the universe come from?

Many of the bosons around just after the big bang were so energetic that they could decay into much more massive particles such as protons (remember, E=mc2, so to make a particle with a large mass m, you need a boson with a high energy E). The mass in the universe came from such decays.

Who created single primordial atom?

Lemaître
Appealing to the new quantum theory of matter, Lemaître argued that the physical universe was initially a single particle—the “primeval atom” as he called it—which disintegrated in an explosion, giving rise to space and time and the expansion of the universe that continues to this day.

What did Georges Lemaitre discover?

Georges Lemaître, (born July 17, 1894, Charleroi, Belgium—died June 20, 1966, Leuven), Belgian astronomer and cosmologist who formulated the modern big-bang theory, which holds that the universe began in a cataclysmic explosion of a small, primeval “super-atom.”

Where did all the mass in the universe come from?

What came first gravity or mass?

Gravity came before mass. According to general relativity it is energy that causes gravity and not mass that causes gravity so the answer is that gravity came before mass. All mass came from energy, but this energy caused (and was affected by) gravity before that already.

What is the origin of the primordial atom?

According to the currently prevailing theory of the origin of the universe, the Big Bang theory, there was no such thing as “the primordial atom”. In fact, it took about 380,000 years after the inception for the first electrically neutral atoms to form.

What is the primordial energy?

Shortly.. Primordial energy was an unstable form of energy, whose nature is not yet known. According to the “inflationary universe” theory primordial energy is what powered the “Big Bang”. At some instant, this energy was transformed into the fundamental particles from which arose all the matter we observe today.

What is the best theory of the origin of the universe?

The discovery and confirmation of the CMB in 1964 secured the Big Bang as the best theory of the origin and evolution of the universe. Much of the current work in cosmology includes understanding how galaxies form in the context of the Big Bang, understanding the physics of the universe at earlier and earlier times,…

How long did it take for atoms to form after Big Bang?

Though simple atomic nuclei formed within the first three minutes after the Big Bang, thousands of years passed before the first electrically neutral atoms formed. The majority of atoms produced by the Big Bang were hydrogen, along with helium and traces of lithium.
