what is the big bang for dummies?

The Big Bang is a scientific theory about how the universe started, and then made the stars and galaxies we see today. ... Then about 13.8 billion years ago, space expanded very quickly (thus the name "Big Bang"). This started the formation of atoms, which eventually led to the formation of stars and galaxies.

The universe is the whole of all matter, energy, planets, galaxies and space. An example of universe is where everyone and everything exists. YourDictionary definition and usage example.

The Big Bang's Playing on TV The cosmic microwave background blankets the universe and is responsible for a sizeable amount of static on your television set--well, before the days of cable. Turn your television to an "in between" channel, and part of the static you'll see is the afterglow of the big bang.

In the first three minutes after the Big Bang, these protons and neutrons began fusing together, forming deuterium (also known as heavy hydrogen). Deuterium atoms then joined up with each other, forming helium-4.

After inflation, the expansion of the universe continued, but at a slower rate. As space expanded, the universe cooled and matter formed, and then protons and neutrons formed. ... So Inflation Theory explains why the CMB is so nearly uniform, and also how galaxies, stars, planets and people came to be!

n (cosmology) the theory that the universe originated sometime between 10 billion and 20 billion years ago from the cataclysmic explosion of a small volume of matter at extremely high density and temperature. Synonyms: big bang theory Type of: scientific theory.

Fred Hoyle famously coined the term “big bang” in 1949, but it took a long time to catch on.

We know the Big Bang happened because right now everything in the universe is moving away from each other thing. It therefore stands to reason that, going back in time, they were all closer together. That's what the Big Bang is; an expansion from the point where everything was together.

In the 1980s, astronomers turned to multiverse theory to explain the “luckily small” amount of dark energy in our universe. According to cosmologist's theories, this small amount of dark energy appeared to enable our universe to host life, while most universes in the multiverse couldn't.

The Big Bang is the singular cataclysmic event that started it all: the instant 13.8 billion years ago that marked the fiery birth of the universe.

If anything, Big Bang's finale is a meditation on the show's own refusal to change. Sheldon and Amy win the Nobel Prize, and after he freaks out about how much of his life is suddenly altered, Sheldon's acceptance speech is about how friends are more important than prizes.

Assuming we're talking about the beginning of time as we know it from the big bang. Take 13.8 billion years ago (13,800,000,000) and assume the calendar still applies, multiply by 3.875e+11 which gives you 5,037,000,000,000 (five trillion, thirty-seven billion) days since the beginning of time since the big bang.

Their detection of the Cosmic Microwave Background (CMB), the radiation left over from the birth of the universe, provided the strongest possible evidence that the universe expanded from an initial violent explosion, known as The Big Bang.

In short, the Big Bang hypothesis states that all of the current and past matter in the Universe came into existence at the same time, roughly 13.8 billion years ago. At this time, all matter was compacted into a very small ball with infinite density and intense heat called a Singularity.

The word universe basically means everything that is, including galaxies and whatever lies between the galaxies. A galaxy is a large collection (millions or billions) of stars held together by gravity. We live in a galaxy called the Milky Way galaxy.

Quarks. Quarks represent the smallest known subatomic particles. These building blocks of matter are considered the new elementary particles, replacing protons, neutrons and electrons as the fundamental particles of the universe.
