Although we can state with confidence where our observable Universe came from, and explain the origin of a great many phenomena within it, the questions of where things like space, time, energy ...
Our knowledge of the events and forces that shaped the early Universe is dependent on our ability to understand the most extreme conditions. On one hand, the Universe’s origin was incomprehensibly small, on dimensions much tinier than the smallest known subatomic particles, and it was completely transformed over an immeasurably brief period, much shorter than any observable time scale. On ...
Theories about the universe's origin and ultimate fate often center on how matter could emerge from nothing. Through an exploration of theoretical constructs like the Planck epoch and quantum fluctuations, alongside Roger Penrose's conformal cyclic cosmology, a picture is painted of a universe cy
Roughly 400 million years after the Big Bang, the universe began to come out of its dark ages. This period in the universe's evolution is called the age of re-ionization.
Perhaps the deepest question of all is that of where we come from. Not just “us” as individuals or human beings, but “us” as in the entire planet, galaxy, and Universe itself.
The origin, evolution, and nature of the universe have fascinated and confounded humankind for centuries. New ideas and major discoveries made during the 20th century transformed cosmology – the term for the way we conceptualize and study the universe – although much remains unknown. Here is the history of the universe according to ...
"Asking the question of, "Where did the entire universe come from?" is no longer a question for poets and theologians and philosophers. This is a question for scientists, and we have some amazing ...
How did the creation of the universe lead to our existence? With the current fleet of Astrophysics missions, researchers are able to study the first stars and galaxies forming out of the darkness of the early universe with state-of-the-art technologies that act as powerful time machines, peering back over 13.5 billion years.
Questions About the Origin of the Universe. Our readers often ask about the origin of the universe and everything in it. “How did it all (the universe, that is) begin—and why, and who (if anyone) was behind it?” — Wonders Liudmyla Kruhlyk. “If the Big Bang was a uniform expansion of space, why did galaxies form?” — Asks Oleh ...
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.
How did the universe come to be? It is perhaps the greatest Great Mystery, and the root of all the others. Humanity's grandest questions — How did life begin?
In 1927, he proposed that the Universe began as a large, pregnant and primeval atom, exploding and sending out the smaller atoms that we see today. His idea went largely unnoticed.
"Asking the question of, "Where did the entire universe come from?" is no longer a question for poets and theologians and philosophers. This is a question fo...
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.
The mysteries surrounding the origin of the universe have captivated our minds for ages, sparking curiosity and contemplation across different eras. Whether through relaying myths, exploring space , or creating modern scientific hypotheses, humanity has sought to unravel the numerous secrets of the cosmos that envelops us.
The very early universe (at a time a few fractions of a second after the Big Bang began) was not bound by the laws of physics as we know them today. So, no one can predict with great accuracy what the universe looked like at that time. Yet, scientists have been able to construct an approximate representation of how the universe evolved.
The universe is big in both space and time and, for much of humankind's history, was beyond the reach of our instruments and our minds. That changed dramatically in the 20th century.
The Era of Atoms (380,000 years – 1 billion years or so) began as the universe finally cooled and expanded enough for the nuclei to capture free electrons, forming fully-fledged, neutral atoms. Previously trapped photons were finally free to move through space, and the universe became transparent for the first time. These photons have been passing through space ever since, forming the cosmic ...
