The process of re-ionization, plus the clearing of foggy hydrogen gas, caused the universe to become transparent to ultraviolet light for the first time. Step 6: More stars and more galaxies
It is a prospect perhaps even more awe-inspiring than a universe with a definite beginning and end, ... Watch physicist Tom Whyntie explain the beginning of the universe for beginners.
The beginning of our universe is one of humanity’s mysteries that have captivated mythologies, philosophies, and scientific endeavors. From cosmological myths depicting primal chaos to contemporary cosmological theories formulated through intricate mathematical study and calculation, our comprehension of how the universe came to exist has ...
How old is the universe, and how did it begin? Throughout history, countless myths and scientific theories have tried to explain the universe's origins. The most widely accepted explanation is the big bang theory. Learn about the explosion that started it all and how the universe grew from the size of an atom to encompass everything in existence today.
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. But what caused this explosion in the first place is still a mystery.
First, the infant universe was initially so hot and dense that even elementary particles such as protons and neutrons could not exist. Instead, different types of matter (called matter and anti-matter) collided together, creating pure energy. As the universe began to cool during the first few minutes, protons and neutrons began to form.
Explain how the first new elements were formed during the first few minutes after the Big Bang; ... It is one thing to say the universe had a beginning (as the equations of general relativity imply) and quite another to describe that beginning. The Belgian priest and cosmologist Georges Lemaître was probably the first to propose a specific ...
The universe became transparent, and for the first time, light could freely travel over great distances. Second, the formation of these first atoms produced its own light. This glow, still detectable today, is called the cosmic microwave background. It is the oldest light we can observe in the universe.
In the beginning, the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.—Douglas Adams, The Hitchhiker's Guide to the Galaxy ... Explained 2 ...
Hubble’s discovery was the first observational support for Georges Lemaître’s Big Bang theory of the universe, proposed in 1927. Lemaître proposed that the universe expanded explosively from an extremely dense and hot state, and continues to expand today. Subsequent calculations have dated this Big Bang to approximately 13.7 billion years ...
The universe is vast beyond comprehension, but our most ambitious thinkers dare to ask: ... Before the Beginning. The universe has a story—a tale that began 13.8 billion years ago, or perhaps long before that. ... Periodic Trends Explained with Simple Tricks; Ophion and the Galactic Puzzle: The Star Family That Broke All the Rules ...
The Universe is thought to have originated 13.8 billion years ago from a very small, extremely hot and dense region called a singularity. The Big Bang was a massive expansion that blew space up ...

Dark matter and dark energy, making up an estimated 95% of all substance in the universe, are still heavily unexplained and remain mysteries. Scientists have struggled to explain why protons, electrons, and neutrons were created from the events of the Big Bang — issues like the existence of antimatter are still shrouded in speculation.
The story of our universe began around 13.8 billion years ago. Cosmos, then the size of a minuscule dot, contained all the existing matter, making it incredibly dense and hot. In what is known as the Big Bang, the universe began to expand and cool down, and our time began to tick. Over time, matter has coalesced into trillions of stars and an inconceivable number of planets, which have grouped ...
The Steady State Universe: Eternal Creation. First proposed by Sir James Jeans in the 1920s, the Steady State hypothesis presents a radically different view of the universe. According to this theory, the universe has neither a beginning nor an end. Instead, as it expands, new matter is continuously created to maintain a consistent density over ...

It is one thing to say the universe had a beginning (as the equations of general relativity imply) and quite another to describe that beginning.

About the Origin and Evolution of the Universe. The origin and evolution of the universe is explained through the Big Bang Theory, which suggests that the universe began around 13.8 billion years ago from a singular, infinitely dense point.; Initially, the universe was a hot, dense plasma. As it expanded rapidly in an event called cosmic inflation, it cooled, allowing particles to form.
