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.
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.
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.
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.
Ever wondered why chainsaws were invented? Contrary to what one might expect, these now-indispensable modern tools possess a startlingly unconventional origin. Dive deeper into their fascinating history, tracing their roots back to the medical field – specifically aiding childbirth and combatting maternal mortality rates.
