How the Big Bang's Leftover Light Reveals What the Universe Is Made Of
The Cosmic Microwave Background (CMB) is faint microwave radiation filling the sky, the richest source of data about the universe's earliest observable moments. By measuring its temperature variations, scientists have determined the universe's composition, including dark energy, dark matter, and ordinary matter.
What are cosmic microwave background origins and significance?
The universe's faint, omnipresent glow, known as the cosmic microwave background (CMB), represents the earliest light detectable by humanity, originating approximately 380,000 years after the Big...
Astronomers Discover New Cosmic Objects: Black Hole Stars
Just 660 million years after the Big Bang, an object dubbed MoM-BH*-1 radiates 100 billion times more energy than any known star, forcing astronomers to rethink how the earliest cosmic giants formed.
Entropy Undermines Cyclic Universe Theory
Each subsequent cosmic cycle would be 'dirtier' and longer than the last, a profound challenge for cyclic universe models.
New Data Reveals Universe Cannot Be Cyclic
The universe is expanding so rapidly that even light from distant galaxies will eventually be stretched beyond our observable horizon, making a 'Big Crunch' and subsequent 'Big Bounce' physically impo
