Skip to comments.Dyson Spheres, The Ultimate Alien Megastructures, Are Missing From The Galaxy

Perhaps the greatest 'holy grail' in all of astronomy is the search for life, and particularly intelligent life, beyond Earth. Given that life arose so plentifully and easily here on our home planet, and that the ingredients for life are everywhere we look throughout the Universe, it seems like a foregone conclusion that we wouldn't be alone. The Milky Way, all on its own, has approximately 400 billion stars, each with its own unique history and chances for life to have arisen. Despite how technologically advanced humans have become, SETI searches have all come up empty, perhaps implying that technologically advanced civilizations aren't communicating in ways we would have thought. But an advanced-enough planet might have built a sphere around their Sun a Dyson sphere to harness 100% of its energy. Incredibly, we now have the technology to detect them. If, that is, they exist.

It's called "the Sock Theory".......Once it's found, a lot of questions will be answered.
Assuming you develop it, you have to ask, "with this much energy, material and technology available, why do I even need a star?"
No, they don't. Perhaps you meant to say they *can* exist?
If so, please refer to post #8
By jove, the emperors new clothes are stunning!
Indeed!! Almost up to the Obama Standards ...
It would take more material than the Solar System has.
What has interested me is that if you look at science fiction before the ‘60’s, they seem to overpredict the mechanical advances we would make, and underpredict advances in electronics and computers.
Thanks C19fan. Not sure we have means to detect one anyway, but I also don't believe for a second that anyone anywhere who had the technology and time involved would ever try to build one.

Well if we are at that point, I might have to get some really good tin foil on!
As an engineer, I struggle with how you harness gravity for power without consuming power. The Three Laws of Thermodynamics apply everywhere.
This story makes the Infinity Wars movie seem like a documentary. What nonsense.

The secret is in the sauce ...
One possibility would be building McNeil cylinders, gaining the living space of a Dyson sphere but with far more versatility.
The other is what we’re doing now, increasingly turning inward to fantasy worlds instead of expanding outward.
Good point. Maybe existed as a 'bridge' between technologies... but not an end product.
The Black Shield of the Schwarzschild radius?
Star Lifting as an alternative?
By chance alone it was impossible for life to have developed on Earth. There is no chance it could have happened anywhere else without a creator the odds are so against it that science had to create the concept of a Multiverse to explain how life could possibly exist on Earth. That’s why we don’t find no alien signals there’s nothing out there.
Also, some technologically-advanced civilizations have probably stolen and applied our stealth technology to their Dyson spheres...
A Dyson sphere would require the resources of several solar system at least, given the star to planet size ratio.
