Our universe started with The explosion of space itself – the big bang. From extremely high densities and temperatures, space expands, the universe cools, and the simplest elements form. Gravity gradually brought matter together, forming the first stars and the first galaxies.

What is the history of the universe?

What is beyond the universe?

To answer the question of what is outside the universe, we first need to define exactly what we mean by « universe. »If you take it literally as all things that may exist in all space and time, then Nothing can exist outside the universe.

How many universes are there?

There There are still some scientists who will say, nonsense.the only meaningful answer to the question how many universes is one, only one universe.

Where does all matter come from?

origin.inside The first moments after the big bang, the universe is very hot and dense. As the universe cooled, conditions became just right to produce the building blocks of matter—quarks and electrons, which we are all made of.

cosmology

• The scientific origin of the universe.
• Hit that drum.
• Big Bang alternative.
• Speed ​​up the universe.
• Plasma Cosmology.
• Standard model.
• Alpha and Omega.
• It’s out of control.

How old is our galaxy?

Most galaxies are Between 10 billion and 13.6 billion years old. Our Universe is about 13.8 billion years old, so most galaxies formed when the Universe was very young! Astronomers believe that our own Milky Way is about 13.6 billion years old.

Will the universe end?

Astronomers once thought the universe might collapse in a big crunch.Most now agree it will end with a big freeze… Trillions of years from now, long after Earth is destroyed, the universe will be torn apart until galaxy and star formation ceases. Slowly, the stars will go out and the night sky will turn black.

Can matter be created?

Water consists of two hydrogen atoms bonded to oxygen atoms. Photo by OJO Images Ltd. From urinals to supernovae, matter makes up everything visible in the known universe.because Matter is never created or destroyedit circulates in our world.

What exactly is dark matter?

Dark matter consists of particles that do not absorb, reflect or emit light, so they cannot be detected by looking at electromagnetic radiation.dark matter is material not directly visible… Scientists believe that dark matter may explain the unexplained motion of stars within galaxies.

What makes space empty?

A point in outer space filled with gas, dust, winds of charged particles from stars, light from stars, cosmic rays, radiation left over from the Big Bang, gravity, electric and magnetic fields, and neutrinos from nuclear reactions. …

How many Earths are there in real life?

NASA estimates 1 billion « Earth » only in our galaxy. Roughly speaking, there are a billion Earths in this galaxy. Not a million. billion.

« Dan DiDio explained that there are 52 Earths, and then alternate dimensions in each universe, and alternate timelines and microverses in each universe. « Many of these worlds are similar to the pre-Crisis and Elseworlds universes, such as Kingdom Come, The Red Son, and The Dark Knight Returns.

How many dimensions are there?

The world as we know it has three dimensions of space– length, width and depth – and the one dimension of time. But there is the puzzling possibility that many more dimensions exist. According to string theory, one of the dominant physical models of the first half century, the universe operates in 10 dimensions.

Does empty space exist?

Like the rest of physics, its properties become puzzling: Empty space is not really empty Because nothing contains something, full of energy and particles, in and out of existence. Physicists have known about quantum mechanics for decades since its inception.

Can we create energy?

The first law of thermodynamics, also known as the law of conservation of energy, states that Energy can neither be created nor destroyed; Energy can only be transferred or changed from one form to another. … in other words, energy cannot be created or destroyed.

Can dark matter be created?

If dark matter is composed of weakly interacting particles, an obvious question is whether it can form the equivalent of planets, stars or black holes.Historically, the answer is it can’tbecause of two factors: it lacks an efficient means of losing energy.
