Here in our Universe, stars shine brightly, providing light and heat to planets, moons, and more. But some objects get even hotter, by far.

It’s not about particle-antiparticle pairs falling into or escaping from a black hole. A deeper explanation alters our view of reality.

50 years ago, Stephen Hawking showed that black holes emit radiation and eventually decay away. That fate may now apply to everything.

McDermitt Caldera, the site of an ancient volcanic eruption, straddles the border of Oregon and Nevada.

Traveling back in time is a staple of science fiction movies. But according to Einstein, it’s a physical possibility that’s truly allowed.

There are a wide variety of theoretical studies that call our Standard Model of cosmology into question. Here’s what they really mean.

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

Since the dawn of history, humans have pondered our ultimate cosmic origins. Now in the 21st century, science has gone beyond the Big Bang.

Welcome to The Nightcrawler — a weekly newsletter from Eric Markowitz covering tech, innovation, and long-term thinking.

Quantum mechanics has taught us that even empty space contains energy. “Negative energy” is the state of having less energy than empty space.

Energy balance is the greatest arbiter of weight gain. Embrace the “oinker diet.”

Welcome to The Nightcrawler — a weekly newsletter from Eric Markowitz covering tech, innovation, and long-term thinking.

Because of dark energy, distant objects speed away from us faster and faster as time goes on. How long before every galaxy is out of reach?

The laws of nature are almost perfectly symmetric between matter and antimatter, and yet our Universe is made ~100% of matter only. But why?

We have very specific predictions for how particles ought to decay. When we look at B-mesons all together, something vital doesn’t add up.

Although a great many unidentified sights have been seen in the skies, none have conclusively demonstrated the presence of aliens. So far.

It’s 2024, and we still only know of the fundamental particles of the Standard Model: nothing more. But these 8 unanswered questions remain.

There was a lot of hype and a lot of nonsense, but also some profoundly major advances. Here are the biggest ones you may have missed.

Bang bang all over the Universe.

When the hot Big Bang first occurred, the Universe reached a maximum temperature never recreated since. What was it like back then?

Since the mid-1960s, the CMB has been identified with the Big Bang’s leftover glow. Could any alternative explanations still work?

For over 50 years, it’s been the scientifically accepted theory describing the origin of the Universe. It’s time we all learned its truths.

In the earliest stages of the hot Big Bang, equal amounts of matter and antimatter should have existed. Why aren’t they equal today?

Capacitors, acid batteries, and other methods of storing electric charges all lose energy over time. These gravity-fed batteries won’t.

When it comes to predicting the energy of empty space, the two leading theories disagree by a factor of 100 googol quintillion.

An enormous amount of antimatter is coming from our galactic center. But the culprit probably isn’t dark matter, but merely neutron stars.

Researchers at the Brookhaven National Laboratory recently created the heaviest exotic antimatter hypernucleus ever observed.

Although the Big Bang occurred at an instant in time long ago, we still see the light from it. Will the evidence ever disappear completely?

How (not) to end up in the ash heap of history.

The second law of thermodynamics is an inviolable law of reality. Here’s what everyone should know about closed, open, and isolated systems.
