Strongest sign of alien found: The search for life beyond earth

Posted by in category: alien life

The search for life beyond Earth is really just getting started, but science has an encouraging early answer: there are plenty of planets in the galaxy, many with similarities to our own. But what we don’t know fills volumes. Observations from the ground and from space have confirmed thousands of planets beyond our solar system.

Scientists Identify Seven Star Systems That May Be Hosting Alien Megastructures

Posted by in category: alien life

Astronomers have identified seven star systems in our galaxy that could potentially host a Dyson sphere — a hypothetical megastructure an alien civilization could build around a star or black hole to capture most of its power in the form of radiation.

The concept, first proposed by theoretical physicist Freeman Dyson in 1960, could take on a number of different shapes, from giant cage structures to ring shells to constellations of mirrors.

Of course, it’s an entirely theoretical idea. After all, we haven’t even discovered the existence of extraterrestrial life, let alone an intelligent alien civilization.

A Study Suggests We Found Potential Evidence of Dyson Spheres—and Alien Civilizations

Posted by in category: alien life

Although scanning this structure remotely could garner more technological advances I do think we need to consider safeguarding earth aswell.

Could unusual starlight patterns be the key to uncovering these mythical megastructures?

3 Body Problem: Is the Universe Really a ‘Dark Forest’ Full of Hostile Aliens in Hiding?

Posted by in categories: alien life, existential risks

This is an issue that the character Ye Wenjie wrestles with in the first episode of Netflix’s 3 Body Problem. Working at a radio observatory, she does finally receive a message from a member of an alien civilization—telling her they are a pacifist and urging her not to respond to the message or Earth will be attacked.

The series will ultimately offer a detailed, elegant solution to the Fermi Paradox, but we will have to wait until the second season.

Or you can read the second book in Cixin Liu’s series, The Dark Forest. Without spoilers, the explanation set out in the books runs as follows: “The universe is a dark forest. Every civilization is an armed hunter stalking through the trees like a ghost, gently pushing aside branches that block the path and trying to tread without sound.”

Where Is Everyone? 4 Possible Explanations for the Fermi Paradox

Posted by in categories: alien life, existential risks

As we go on with our everyday lives, it’s very easy to forget about the sheer size of the universe.

The Earth may seem like a mighty place, but it’s practically a grain within a grain of sand in a universe that is estimated to contain over 200 billion galaxies. That’s something to think about the next time you take life too seriously.

So when we gaze up into the starry night sky, we have every reason to be awestruck—and overwhelmed with curiosity. With the sheer size of the universe and the number of galaxies, stars, and planets in it, surely there are other sentient beings out there. But how come we haven’t heard from them?

The Transcension Hypothesis, John M. Smart, 2011

Posted by in categories: alien life, engineering

Keywords: With sufficiently advanced SETI, we might discover brief broadcasts or occasional episodes of minor galactic engineering occurring in small portions of a very few galaxies. But because of the acceleration of complexification and the vast distances between civilizations, it seems impossible that even an earliest-to-emerge civilization, however oligarchic, could prevent multi-local transcensions in any galaxy. In theory, one can imagine a contrarian civilization releasing interstellar probes, carefully designed not to increase their intelligence (and so, never be able to transcend) as they replicate. But what could such probes do besides extinguish primitive life? They certainly couldn’t prevent multilocal transcensions. There seems no game theoretic value to such a strategy, in a universe dominated by accelerating transcension. Finally, if constrained transcension is the overwhelming norm, we should have much greater success searching for the norm, not the rare exception. As Cirkovic (2008) and Shostak (2010) have recently argued, we need SETI strategies that focus on places where advanced postbiological civilizations are likely to live. In the transcension hypothesis, this injunction would include using optical SETI to discover the galactic transcension zone, and define its outward-growing edge. We should look for rapid and artificial processes of formation of planet-mass black holes, for leakage signals and early METI emanating from life-supporting planets, and for the regular cessation of these signals as or soon after these civilizations enter into their technological singularities.

Why The “Goldilocks” Zone of Habitable Planets is Outdated When Searching for Life

Posted by in category: alien life

Many more places with Life are likely to exist outside the so-called Habitable Zone (HZ) and they are getting more and more… New post on BigThink, direct link to it at.

“The universe is a hologram,” Stephen Hawking’s closest collaborator explains his final theory

Posted by in categories: alien life, holograms, quantum physics

Close friend and coworker Thomas Hertog explores the groundbreaking physicist’s theories regarding the Big Bang’s beginnings on this, the sixth anniversary of Stephen Hawking’s passing.

I was appointed as Stephen Hawking’s PhD student in 1998 “to work on a quantum theory of the Big Bang.” Over the course of about 20 years, what began as a doctoral project evolved into a close collaboration that came to an end only six years ago, on March 14, 2018, when he passed away.

The mystery that drove our investigation during this time was how the Big Bang could have produced conditions that were so ideal for life. How should we interpret this enigmatic display of intent?

Cosmism and the Future of Religion, with Giulio Prisco

Posted by in categories: alien life, futurism

Future science and technology will permit playing with the building blocks of space, time, matter, energy, and life, in ways that we could only call magic and supernatural today. Someday in the future, you and your loved ones will be resurrected by very advanced science and technology. Inconceivably advanced intelligences are out there among the stars. Even more God-like beings operate in the fabric of reality underneath spacetime, or beyond spacetime, and control the universe. Future science will allow us to find them, and become like them.

These claims are made on the opening page of the book \.

Mysterious Objects in Space Could Be Giant Dyson Spheres, Scientists Say

Posted by in category: alien life

Scientists have discovered mysterious objects in space that could potentially be giant Dyson Spheres, structures built by advanced civilizations to harness the energy of their stars. This discovery is both exciting and poetic, as it represents humanity’s ongoing search for other intelligent life in the vast expanse of the Milky Way. While the objects have not yet been confirmed as Dyson Spheres, the possibility alone is enough to spark curiosity and wonder about the potential for other civilizations in our universe.
