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 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 […]
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 […]
How long should one wait until an idea like string theory, seductive as it may be, is deemed unrealistic?
We only detected our very first gravitational wave in 2015. Over the next two decades, we’ll have thousands more.
If you think you know how an astronomical nova works, buckle up. You’re in for a ride like you never expected.
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.
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 […]
Reduction is an approach that has been successful in science but is not itself synonymous with “science.”
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.
Even with only 12.5 hours of exposure time, James Webb’s first deep-field image taught us lessons we’ve never realized before.
Over time, the Universe becomes less dominated by dark matter and more dominated by dark energy. Is one transforming into the other?
Our Universe requires dark matter in order to make sense of things, astrophysically. Could massive photons do the trick?
As we gain new knowledge, our scientific picture of how the Universe works must evolve. This is a feature of the Big Bang, not a bug.
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 […]
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 […]
The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?
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 […]
The double-slit experiment, all these years later, still holds the key mystery at the heart of quantum physics. When we divide up matter into the smallest possible chunks that it’s made […]
You can lead an overconfident chatbot to expert knowledge, but can it actually learn and assimilate new information?
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 […]
If the electromagnetic and weak forces unify to make the electroweak force, maybe, at even higher energies, something even greater happens?
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 […]
We used to think the Big Bang meant the universe began from a singularity. Nearly 100 years later, we’re not so sure.
Forget about the terawatt lasers we’re making on Earth. This natural one is thousands of times more powerful than the Sun.
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 […]
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 […]
Time always moves in the same direction, but what if the Universe were contracting? As we step forward in time, a number of things always seem to happen together. Objects […]
