http://www.independent.co.uk/news/w...structures-orbiting-a-star-near-a6693886.html So who believes in life outside our world?
I just read this before you posted http://www.theatlantic.com/notes/2015/10/maybe-its-a-dyson-sphere/410974/ While there is no proof and I'm sure red will be along to point that out it is impossible to believe that out of the trillions of galaxies each containing trillions of stars that we are the only sentient life forms in the universe.
Life outside our world must certainly exist, but failing clear radio signals, it will be impossible to ever know. But this is not evidence of it. It is raw speculation that any civilization could build space structures this immense to cause blockage of light from a sun. It is almost certainly a fragmented planet from a comet collision, a cluster of asteroids or some other natural phenomenon. And while life may exist elsewhere, it is entirely possible that only we have advanced far enough to become sentient.
That would only be remotely possible if God created the Earth and life and nowhere else among the quintillions of planets that surely exist. And sentient life forms could be so vastly different from us that we wouldn't even recognize it. And surely we are not the most advanced life forms in the universe. There are galaxies far older than ours
Of course. But we can forget about ever contacting other galaxies. Still in all the universe, there is a civilization that is the most advanced. It could be us. Certainly nobody in our corner of the galaxy is emitting radio waves like us. We will remain the most advanced civilization in the known universe until we discover a more advanced one.
Microbiological life is a possibility. That's about it. In any star system there can be only a planet or two with the right density atmosphere, enough water, and the right distance from the sun to sustain life.
How do you know they even use radio? A different form of life could have developed a totally different form of communication and method of disseminating information.
Does Europa have a heated core? If so there is a good chance there is liquid water and hydrothermal activity, which could produce life.
