All scientific theories are limited in scope, power, and application, being mere approximations of reality. That's why consensus is vital.
A tilted spiral galaxy gracefully tipped towards the viewer reveals a bright core and dark, dusty rings, set against the infinity of deep blue space.
When we see spiral galaxies, some are face-on, others are edge-on, but most are tipped at an angle. But which side is closest to us?

The tiniest galaxies of all are the most susceptible to violence by their larger, bullying siblings. That's why we need them in isolation.
A vivid image of a bright, colorful galaxy with swirling red, blue, and white clouds of gas and dust, where galaxies collide amid distant stars in the dark, expanding universe.
The Universe is expanding, and individual, bound structures are all receding away from one another. How, then, are galaxies still colliding?
Collage featuring a hand filing papers, an airplane, and numerical data on a grid background. Text reads "The Night Crawler: A Journey for Investigative Investors.
Welcome to The Nightcrawler — a weekly newsletter from Eric Markowitz covering tech, innovation, and long-term thinking.
A red star is at the center, with five orbiting paths marked by yellow dots, resembling exoplanets around the nearest single star, set against a starry night backdrop that illustrates a planetary system.
Barnard's star, the closest singlet star system to ours, has long been a target for planet-hunters. We've finally confirmed it: they exist!
A group of five men in suits pose with model rockets, showcasing their commitment to fundamental research. Beside them, an illustration depicts a space station orbiting Earth and the Moon, highlighting their visionary investment in space exploration.
Back in 1970, Sister Mary Jucunda wrote NASA, decrying large investments in science. A former Nazi's legendary response is still relevant.
Two faceless busts face each other. One, representing AI, has digital lines on its face, while the other exudes cognitive meaning with flowers and leaves emerging from its surface.
Cognitive neuroscientist and AI researcher Christopher Summerfield explores the differences, and similarities, of how AI and humans make meaning of the world.
Text "Cosmic Origins" over a bright, colorful explosion effect with star-like patterns in the background.
Since the dawn of history, humans have pondered our ultimate cosmic origins. Now in the 21st century, science has gone beyond the Big Bang.
Illustration shows a supermassive black hole with a captured star and hypervelocity star, near the Large Magellanic Cloud, with double star orbits labeled. Earth is visible in the foreground.
Just 165,000 light-years away, the Large Magellanic Cloud is suspected to house a supermassive black hole. At last, evidence has arrived.

Fears of celestial collisions — and calculations of their likelihood — go back to the very origins of modern science itself.
Green glowing orbs and funnel-shaped structures with light patterns floating in a vibrant green misty background.
There are some 26 fundamental constants in nature, and their values enable our Universe to exist as it does. But where do they come from?
A stylized image showcases poker chips and a green Swiss army knife, intricately overlaid with circuit patterns, hinting subtly at AI risk. The word "Nightcrawler" graces the top, adding an enigmatic touch.

Under extreme conditions, matter takes on properties that lead to remarkable, novel possibilities. Topological superconductors included.
Two images of the Sombrero Galaxy reveal its beauty: one with a bluish hue showcasing visible details, and the other with a reddish hue highlighting a different spectrum. Captured by JWST, these images offer an unmatched view of this spiral galaxy's complex structure.
One of the most promising dark matter candidates is light particles, like axions. With JWST, we can rule out many of those options already.
Laser guide star
Astronomers see spiral and elliptical nebulae nearly everywhere, except by the Milky Way's plane. We didn't know why until the 20th century.
warp field stars
Perhaps the most well-known equation in all of physics is Einstein's E = mc². Does mass or energy increase, then, near the speed of light?
An astronaut stands proudly on the moon's surface near scientific equipment and a lunar lander, as the American flag waves in the background, symbolizing a pioneering USA nation.
We've wasted our time and resources ideologically policing and punishing each other for far too long. Here's a better route to prosperity.

“I want to change the way we think about the past altogether,” says Dr. Betül Kaçar, an astrobiologist who studies the origin of life.
