First derived by Emmy Noether, for every symmetry a theory possesses, there’s an associated conserved quantity. Here’s the profound link.

Human civilization has always survived periods of change. Will our rapidly evolving technological era be an exception to the rule?
“If you’re training an AI to optimize for a task, and deception is a good way for it to complete the task, then there’s a good chance that it will use deception.”
The idea of awarding legal personhood to nature has received renewed attention in the contemporary environmental justice movement, but much contention remains.
The Bullet Cluster has, for nearly 20 years, been hailed as an empirical “proof” of dark matter. Can their detractors explain it away?
The military is courting tech startups to help it win the AI arms race.
Some scientists think we should allow our bodies to more harmlessly live with pathogens until they’re cleared from our systems.
Welcome to The Nightcrawler — a weekly newsletter from Eric Markowitz covering tech, innovation, and long-term thinking.
Laser-guided lightning systems could someday offer much greater protection than lightning rods.
From landscaped gardens to road systems, the Persians were among the first to create many things we still enjoy today.
Boys are four times as likely as girls to develop autism. Girls are nearly twice as likely to experience depression. The immune system may be a player in these and other brain-health disparities.
Imagine going on a tour through the human circulatory system as a tiny cell. That is just one example of education in the metaverse.
When we’re stressed, our hormones and nervous system produce all sorts of odors.
Our “embodied minds” suggest an eventual escape from mortality via computer is unlikely.
Gravitational waves carry enormous amounts of energy, but spread out quickly once they leave the source. Could they ever create black holes?
The controversial theory about magic mushrooms and human evolution gets a much-needed update.
Western societies seem to be getting inflammation achingly wrong.
People with higher immune resilience live longer, resist diseases, and are more likely to survive diseases when they do develop.
AI has become a black box in more ways than one.
Black holes encode information on their surfaces, but evaporate away into Hawking radiation. Is that information preserved, and if so, how?
It would get rid of our hazardous, radioactive, and pollutive waste for good, but physics tells us it’s a losing strategy for elimination.
At extremely close distances to their stars, even rocky planets can be completely disintegrated. We’ve just caught our first one in action.
Even with the best technology imaginable, you’d probably never be able to exist as a consciously aware brain in a vat.
Making up false information is one of the biggest problems with AI, but there are no silver-bullet solutions.
Electromagnetism, both nuclear forces, and even the Higgs force are mediated by known bosons. What about gravity? Does it require gravitons?
The Universe isn’t just expansion, but the expansion itself is accelerating. So why can’t we feel it in any measurable way?
The last infant stars are finishing their formation inside these pillars of gas. The evaporation of those columns is almost complete.
Massive objects like black holes, stars, and rogue planets routinely pass near our Solar System. An ensuing comet storm could destroy us.
“Neurotech is not just about the brain,” says Synchron CTO Riki Banerjee, explaining how their tech can help with paralysis, brain diseases, and beyond.
