Science & Tech

Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.

Welcome to The Nightcrawler — a weekly newsletter from Eric Markowitz covering tech, innovation, and long-term thinking.
gravitational wave effects on spacetime
Gravitational waves are the last signatures that are emitted by merging black holes. What happens when these two phenomena meet in space?

DESI has allowed astronomers to create an unprecedented 3D map of the Universe representing 20% of the entire sky.
lookback time galaxies
For nearly 60 years, the hot Big Bang has been accepted as the best story of our cosmic origin. Could the Steady-State theory be possible?

In November 1974, astronomers used the radio telescope at Puerto Rico’s Arecibo Observatory to send a hello to the universe.
how much dark matter
Two parts of our Universe that seem to be unavoidable are dark matter and dark energy. Could they really be two aspects of the same thing?

"A person’s mass is made not of 'stuff' in the way we normally think about it, but rather our mass is made of energy."

"I was stunned. Here in front of me was the original apparatus through which a new vision of the world was slowly and painfully brought to light."

Scalars, vectors, and tensors come up all the time in physics. They're more than mathematical structures. They help describe the Universe.

They’re in our brains, hearts, and blood — but what are they doing to us?

We need a "theory that explains the evolution of evolution," argues theoretical physicist Sara Imari Walker.

Storytelling skills are not just for entertainment — practical exercises used by the cream of Hollywood can transform your work-life.
Three red, cloud-like structures are set against a starry background in space.
The most massive early galaxies grew up faster, and have more stars, than astronomers expected, according to JWST. What does it all mean?

While we’re busy wondering whether machines will ever become conscious, we rarely stop to ask: What happens to us?
