Where did the atoms come from to cause the Big Bang?

As the universe cooled, conditions became just right to give rise to the building blocks of matter – the quarks and electrons of which we are all made. A few millionths of a second later, quarks aggregated to produce protons and neutrons. Within minutes, these protons and neutrons combined into nuclei.

How did everything begin in the Big Bang?

The Big Bang theory says that the universe came into being from a single, unimaginably hot and dense point (aka, a singularity) more than 13 billion years ago. It didn’t occur in an already existing space. Rather, it initiated the expansion—and cooling—of space itself.

How was atom discovered?

The idea of atoms stretches back to ancient Greece when the philosopher Democritus declared that all matter is made of tiny particles. The first modern evidence for atoms appears in the early 1800s when British chemist John Dalton discovered that chemicals always contain whole number ratios of atoms.

Are humans made of atom?

About 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. You also contain much smaller amounts of the other elements that are essential for life. The hydrogen atoms in you were produced in the big bang, and the carbon, nitrogen and oxygen atoms were made in burning stars.

What caused the Big Bang to happen?

Before the Big Bang there was no space or time. So, it is actually meaningless to ask what caused the Big Bang to happen – there was no Universe in which that cause could have existed. This might seem like a bit of a cheat, but there are other good reasons to suppose a cause for the Big Bang might not exist.

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.

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,…

Is the Big Bang theory a theory of creation?

Let me take this opportunity to be precisely, abundantly, emphatically, ridiculously, fantastically clear: The Big Bang theory is not a theory of the creation of the universe. Full stop. Done. Call it. Burn that sentence into your brain. Say it before you go to sleep, and first thing when you wake up.
