The answer to this question is key to understanding why anything exists.
We frequently say it's 2.725 K: from the light left over all the way from the Big Bang. But that's not all that's in the Universe.
In the 20th century, many options abounded as to our cosmic origins. Today, only the Big Bang survives, thanks to this critical evidence.
There's an extra source of massive "stuff" in our Universe beyond what gravitation and normal matter can explain. Could light be the answer?
Is fasting the key to burning fat? It's not that simple.
In the wake of the pandemic, the crystal industry boomed, with customers hoping the stones might relieve a little anxiety.
The world is aging, and with age comes vision decline. New research may have found how to improve eyesight in an accessible way.
The big-picture physics is simple – let gravity do its job.
Earth is not a benign mother. We have begun to witness what happens when it unleashes its fury.
No matter what physical system we consider, nature always obeys the same fundamental laws. Must it be this way, and if so, why?
Everything that gets heated up has to, somehow, radiate that energy away. Here's what we see when that happens in the Universe.
Humanity is in trouble. Here's how aliens could help.
This technological feat changes our cosmic history.
All the things that surround and compose us didn't always exist. But describing their origin depends on what 'nothing' means.
Much like energy and nutrients flow in a continuous cycle between the elements of a natural ecosystem, a free flow of knowledge fuels the growth of a learning ecosystem.
As particles travel through the Universe, there's a speed limit to how fast they're allowed to go. No, not the speed of light: below it.
From before the Big Bang to the present day, the Universe goes through many eras. Dark energy heralds the final one.
For over three decades, toxic proteins were believed to cause Alzheimer’s disease. However, recent studies suggest it might be metabolic reprogramming.
Short-hop regional flights could be running on batteries in a few years.
Drop sodium in water, and a violent, even explosive reaction will occur. But quantum physics is needed to explain why.
In our common experience, you can't get something for nothing. In the quantum realm, something really can emerge from nothing.
There are two fundamentally different ways of measuring the Universe's expansion. They disagree. "Early dark energy" might save us.
Do the laws of physics place a hard limit on how far technology can advance, or can we re-write those laws?
Germany finds itself once again allowing a murderous dictator to run rampant in Europe, though this time it is due to incompetence and technophobia rather than malice.
If the electromagnetic and weak forces unify to make the electroweak force, maybe, at even higher energies, something even greater happens?
∆G = ∆H - T∆S is one of the most abstract formulas in science, but it is also one of the most important. Without it, life cannot exist.
Billions of years ago, the ever-increasing entropy must've been much lower: the past hypothesis. Here's how cosmic inflation solves it.
At very high and very low temperatures, matter takes on properties that open up an entire Universe of remarkable new possibilities.
A non-invasive method for looking inside structures is solving mysteries about the ancient pyramid.
