The Dark Forest Theory is a thought experiment about the behavior of extraterrestrial intelligence. It suggests that alien life exists in the galaxy and if they discover us, they may attempt to kill us to protect themselves.

In 1974, researchers sent a greeting to extraterrestrial life using the world’s largest radio telescope. The signal was directed towards a star cluster 25,000 light-years away. This is the story of the Arecibo message.

For 72 seconds on August 15, 1977, a radio telescope in Ohio detected what may have been a signal from extraterrestrial intelligence. It was a narrow-band burst of radio waves, matching no known natural phenomenon, and it stood out like a sore thumb from the ordinary background noise of the cosmos.

The Voyager Golden Record, sent on Voyager 1 and Voyager 2 in 1977 by NASA, is a time capsule that showcases human civilization and aims to communicate the essence of Earth to beings beyond our planet. The Golden Record, which includes 115 pictures, greetings in 55 languages, natural sounds, and 90 minutes of diverse music, marks humanity’s initial attempt to explore beyond our solar system.

Taste the past, shape the future. In an effort to spark conversation about the future of food and sustainable meat alternatives, an Australian startup has showcased a meatball made from lab-grown cultured meat using genetic material from the long-extinct woolly mammoth.

It’s obvious to any stargazer on a clear night that we live in a universe vast beyond imagining, glittering with worlds besides our own—and yet, as far as we know, Earth is the only planet to have developed living creatures of any kind. Intelligent life is an unrepeated experiment, with a sample size of one. Could we really be alone?

At the Boomerang Nebula, 5,000 light-years away, a dying star is shooting out gas so quickly that it actually cools down as it expands; the surrounding clouds are barely above absolute zero, making it the coldest place in the universe.

Once a waste product of the automobile industry, fordite—which is pretty much a fancy name for hardened car paint slag—is now a treasured material among jewelry makers and lapidary artists. It’s just too beautiful not to be.

If you’ve ever watched the movie Interstellar, that final scene, at Cooper Station, happens in an O’Neill cylinder. First envisioned by a Princeton professor and his undergraduate students in 1974, it was recently popularized as our preferred way to colonize space. Jeff Bezos fully endorses that statement.

In 1974, British theoretical physicist Stephen Hawking predicted that, owing to quantum effects, black holes must constantly emit a small amount of radiation, which should eventually cause them to evaporate—entirely! It turns out he was right.

Even though identical twins share a lot—from their birthday and DNA through their sex and height to their skin, eye, and hair color—remarkably, they do not share the same fingerprints. Here’s why.

The Dyson Sphere, a thrilling concept steeped in cosmic potential, fires up our imagination about the future of human capabilities. Not just a blueprint for megastructures, it also serves as a compass, guiding our exploration in the ever-elusive search for extraterrestrial civilizations.

You’d think answering a simple question like why people yawn would be simple. However, it’s not straightforward despite extensive scientific research.

Scientists posit that Earth’s very life-force—oxygen—along with dust particles and our planet’s magnetotail, conspire in a cosmic dance to set the stage for an unexpected phenomenon: the Moon’s rusting.

Ever wondered about horsepower? It’s a game of averages. Let’s delve into the answer to how much horsepower does a horse have.

Standard mirrors are not perfectly smooth due to structural irregularities For this reason most mirrors reflect green light better.

As space exploration expands, space blindness emerges as a grave consequence of extended stays beyond Earth. Can scientists conquer this challenge in time for the impending Mars mission? Unveiling their strategies becomes paramount on the path to interplanetary journeys.
