The Universe as we observe it today began with the hot Big Bang : an early hot, dense, uniform, ... ... Perhaps, according to cosmic inflation
How did the universe actually start?
The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began. ... The matter that spread out from the Big Bang developed into everything in the universe, including you.
Who said the universe came from nothing?
NEW YORK, March 4 (Xinhua) — “There was nothing around before the Big, Big Bang,” British physicist Stephen Hawking said during a TV talk show aired Sunday on National Geographic Channel, propounding his theory on what happened before the universe came into existence.
How was matter created from nothing?
On one hand, there is no known way, given the particles and their interactions in the Universe, to make more matter than antimatter . ... This creation-and-annihilation process, which obeys E = mc^2, is the only known way to create and destroy matter or antimatter.
Who created the universe?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
What is outside the universe?
To answer the question of what’s outside the universe, we first need to define exactly what we mean by “universe.” If you take it to mean literally all the things that could possibly exist in all of space and time, then there can’t be anything outside the universe .
Where did all matter come from?
Origins. In the first moments after the Big Bang , the universe was extremely hot and dense. 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.
Does empty space exist?
And as in the rest of physics, its nature has turned out to be mind-bendingly weird: Empty space is not really empty because nothing contains something, seething with energy and particles that flit into and out of existence. Physicists have known that much for decades, ever since the birth of quantum mechanics.
Can matter be created?
Matter can change form through physical and chemical changes , but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
Who is the first God?
Brahma is the Hindu creator god. He is also known as the Grandfather and as a later equivalent of Prajapati, the primeval first god. In early Hindu sources such as the Mahabharata, Brahma is supreme in the triad of great Hindu gods which includes Shiva and Vishnu.
Who was the very first God?
Brahma is the Hindu creator god. He is also known as the Grandfather and as a later equivalent of Prajapati, the primeval first god. In early Hindu sources such as the Mahabharata, Brahma is supreme in the triad of great Hindu gods which includes Shiva and Vishnu.
Who is the real God?
In monotheistic thought, God is conceived of as the supreme being, creator, and principal object of faith. God is usually conceived of as being omnipotent, omniscient, omnipresent and omnibenevolent as well as having an eternal and necessary existence.
Does the universe have an end?
The end result is unknown ; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
Does the universe go on forever?
The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs ( 46.5 billion light-years or 4.40×10 26 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×10 26 m).
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 .
Does nothingness exist?
There is no such thing as nothingness , and zero does not exist. Everything is something. Nothing is nothing.
