Although humans have only sent a couple of tentative signals into space, many are concerned about the risks. Should we let alien civilizations know we’re here? According to a new paper, humanity has already been broadcasting its existence for thousands of years, and civilizations with advanced enough technology should be able to observe us. It’s science fiction to us, but megastructure space telescopes could have baselines of millions of kilometers, powerful enough to detect structures on the surface of Earth from thousands of light-years away.
The hunt for alien life and its radio signals from beyond our Solar System is still coming up dry. But, it’s not for lack of looking for possible advanced civilizations.
Did humanity miss the party? Are SETI, the Drake Equation, and the Fermi Paradox all just artifacts of our ignorance about Advanced Life in the Universe? And if we are wrong, how would we know? A new study focusing on black holes and their powerful effect on star formation suggests that we, as advanced life, …
Are there civilizations somewhere else in the Universe? Somewhere else in the Milky Way? That’s one of our overarching questions, and an answer in the affirmative would be profound. Humanity’s pursued the Search for Extraterrestrial Intelligence (SETI) in one form or another since shortly after the advent of radio waves in the early 20th century. …
A new online tool created by a team of physicists allows users to calculate how many alien civilization could be out there for themselves!
In the ongoing search for intelligent life, a new study recommends that we look for signs of an advanced civilization harnessing the power of neutrinos to create a beacon.
In a recently published paper, Dr. Duncan Forgan proposed that alien civilizations could create a “galactic internet” by using artificial transits to communicate.
A new paper by two Harvard professors explores the idea of using supernova as a means of high-speed interstellar travel – something advanced alien species could be doing right now!
A new study recommends looking for Dyson Spheres that are smaller, orbit closer to their suns, and might still be under construction.
The first early humans to use fire had no inkling of what it would lead to. Fire was one of our first technologies, and humans have been making changes to their environments since the advent of controlled fire hundreds of thousands of years ago. Fast forward to current times, and our modern technological and global …
