Over time, the Universe becomes less dominated by dark matter and more dominated by dark energy. Is one transforming into the other?

As far as we can tell, there’s no limit to how far it goes on; only a limit to how far we can see. Could the Universe truly be infinite?

Even the most brilliant mind in history couldn’t have achieved all he did without significant help from the minds of others.

It’s perhaps the most famous thought experiment in all of physics, but is full of popular myths and misconceptions. One of the most bizarre ideas about the quantum Universe is […]

Our Universe requires dark matter in order to make sense of things, astrophysically. Could massive photons do the trick?

There’s a lot to get rid of if we want to get only our Universe out of String Theory. A lot of people, when they learn about String Theory for the […]

The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?

If we waited long enough, would even protons themselves decay? There are certain things in the Universe that, if you leave them alone for long enough, they’ll eventually decay away. […]

Researchers devise groundbreaking new methods to create and duplicate single-atom transistors for quantum computers.

We live in a world dominated by science, but most people don’t understand its most essential characteristic: establishing standards of evidence to keep us from getting fooled by our own biases and opinions.

How long should one wait until an idea like string theory, seductive as it may be, is deemed unrealistic?

Reduction is an approach that has been successful in science but is not itself synonymous with “science.”

If the electromagnetic and weak forces unify to make the electroweak force, maybe, at even higher energies, something even greater happens?

The biggest error from ‘A Brief History of Time’ continues to misinform generations of aspiring physicists. The greatest idea of Stephen Hawking’s scientific career truly revolutionized how we think about […]

Forget about the terawatt lasers we’re making on Earth. This natural one is thousands of times more powerful than the Sun.

Without quantum physics, the Sun wouldn’t shine at all. Earth, as we know it, is only teeming with life because of the influence of our Sun. Its light and heat provides […]

The anthropic principle has some fascinating scientific uses. And abuses, too. For thousands of years, humans have pondered the meaning of our existence. From philosophers who debated whether their minds could […]

Or is ‘new space’ created in between the gaps of the ‘old’ space? It’s been almost 100 years since humanity first reached a revolutionary conclusion about our Universe: space itself doesn’t […]

We used to think the Big Bang meant the universe began from a singularity. Nearly 100 years later, we’re not so sure.

We have to use the right definition for the specific question we’re asking. When it comes to the Universe, we frequently characterize objects by examining and reporting on their physical […]

To answer any physical question, you must ask the Universe itself. But what happens when the answers aren’t around anymore?

The new record-holder opens up a literal Universe full of possibilities. Someday, even our own Sun will eventually run out of hydrogen fuel in its core, bringing a tremendous set […]

Forgetting them, at any step, can lead to unscientific conclusions. No one, not even the smartest among us, were competent scientists from the outset. The concept of science is simple […]

Our ultimate fate depends on something we’ve barely begun to measure. One of the biggest mysteries in all of physics is dark energy. According to our best observations, the Universe cannot […]

In theory, the fabric of space could have been curved in any way imaginable. So why is the Universe flat when we measure it?

Make it so.

If the laws of physics are symmetrical as we think they are, then the Big Bang should have created matter and antimatter in the same amount.

The theoretical reasons to expect it are compelling, but the technology required to detect it is unfathomable. All throughout our galaxy, millions of black holes of a variety of masses […]

Of all the injustices in Nobel Prize history, her 1957 Nobel snub is the most egregious. One of the biggest scientific revolutions of the 20th century was the discovery of […]

Many contrarians dispute that cosmic inflation occurred. The evidence says otherwise.
