The universe is often defined as the totality of existence, or everything that exists, everything that has existed, and everything that will exist. In fact, some philosophers and scientists support the inclusion of ideas and abstract concepts—such as mathematics and logic—in the definition of the universe.

Who came up with the idea of the universe?

A Belgian priest named Georges Lemaître first suggested the big bang theory in the 1920s, when he theorized that the universe began from a single primordial atom.

What created the universe?

Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.

What is the theory of the universe?

The Big Bang theory is the prevailing cosmological model explaining the existence of the observable universe from the earliest known periods through its subsequent large-scale evolution.

What is the main purpose of the universe?

The universe is governed by laws of nature that themselves have no purpose other than dictating what matter and energy do. Stars, for example, convert hydrogen into helium, and they have no choice in the matter once they reach a certain size and temperature.

How many universes are there?

There are still some scientists who would say, hogwash. The only meaningful answer to the question of how many universes there are is one, only one universe.

What is beyond the Universe?

Nearby, the stars and galaxies we see look very much like our own. In our own backyard, the Universe is full of stars. But go more than about 100,000 light years away, and youve left the Milky Way behind. Beyond that, theres a sea of galaxies: perhaps two trillion in total contained in our observable Universe.

Does life have a purpose?

All life forms have one essential purpose: survival. This is even more important than reproduction. After all, babies and grannies are alive but dont reproduce. Life is a form of material organization that strives to perpetuate itself.

How many Earths are there in real life?

Scientists are excited by the possibilities. Out of those 40 billion Earth-like planets, how many other worlds might there be that support life? These same scientists have concluded that planets like Earth are relatively common throughout the Milky Way galaxy.

Does the universe have an end?

The universe, being all there is, is infinitely big and has no edge, so theres no outside to even talk about. Oh, sure, theres an outside to our observable patch of the universe. The cosmos is only so old, and light only travels so fast. The current width of the observable universe is about 90 billion light-years.

What is the purpose of human existence?

The main purpose of our existence is to live with peace and to serve God ,learn,work and help peoples while need to help.

Does the galaxy have an end?

Thats accounting for the increase in star formation when the Milky Way and the Andromeda Galaxy collide around that time. Thus, some 19 billion years after the Big Bang, the Milky Way will begin its slow but inexorable decline — and, a trillion years from now, the end will come as its last star fades from visibility.
