...it brings me back to the Urantia Book, even though I no longer have a lot of faith in said book.
If it were a Dyson sphere, it would be a lot more massive than the current estimates, and it would also have to be a Dyson shell.

Hurray for technolgy!
They can find a planet, which casts no light of it's own, at a distance of 80 light years.
Yet, they have trouble finding a way to find and keep up with the many near-earth objects which could end life on our planet.
You would think someone would develope a simple means of keeping these things in check. It will only take one and ......

Hi again, wildespace. Would you (or anyone else here) be able to calculate the radius of a sphere that would radiate the equivalent energy of a G-type star of 1 sol mass at the frequency at which this object was detected?
I only ask because I'm sure you would do it a lot faster than I... and correctly to boot.
I also read about stars that don't have a galaxy. (anymore) In the same way that
a planet can be hurled out of a solar system, a star can be hurled out of a galaxy.
Scientists have actually found a planet that has no parent star, which they've named PSO J318.5-2.
....from what I read they detected it via its heat signature, which means the planet -has- heat. Don't planets NEED their parent stars FOR heat?
