How close to the Big Bang can we see?

46.1 billion light-years
It’s been 13.8 billion years since the Big Bang, which might lead you to expect that the farthest objects we can possibly see are 13.8 billion light-years away. But not only isn’t that true, the farthest distance we can see is more than three times as remote: 46.1 billion light-years. How can we see so far away?

How many seconds after the Big Bang can we see?

Background Radiation According to the theories of physics, if we were to look at the Universe one second after the Big Bang, what we would see is a 10-billion degree sea of neutrons, protons, electrons, anti-electrons (positrons), photons, and neutrinos.

What happens 1 minute after the Big Bang?

As space expanded, the universe cooled and matter formed. One second after the Big Bang, the universe was filled with neutrons, protons, electrons, anti-electrons, photons and neutrinos. During the first three minutes of the universe, the light elements were born during a process known as Big Bang nucleosynthesis.

What happened when the universe cooled below 3000 K?

380,000 years after the Big Bang – The temperature of the universe had cooled to about 3000 K. As the universe expanded, pockets of gas became more dense and and stars began to ignite. Groups of these stars became early galaxies.

How hot was the universe after the Big Bang?

In contrast, cosmologists believe the Big Bang flung energy in all directions at the speed of light (300,000,000 meters per second, a million times faster than the H-bomb) and estimate that the temperature of the entire universe was 1000 trillion degrees Celsius at just a tiny fraction of a second after the explosion.

Where did the Big Bang happen?

The Big Bang happened everywhere. It happened right where you are sitting, where the Andreomeda galaxy is now, and in the most distant reaches of the universe. It’s just that the reaches of the universe were not quite as distant those many billions of years ago.

What was the earliest time in the universe?

However, the earliest times of the Universe – lasting from approximately 10 -43 to 10 -11 seconds after the Big Bang – are the subject of extensive speculation. Given that the laws of physics as we know them could not have existed at this time, it is difficult to fathom how the Universe could have been governed.

How did the Big Bang theory explain the evolution of universe?

Big Bang Theory: Evolution of Our Universe. 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.
