We are not alone?

[westwall]

The sad part is we will never be able to study any life "out there" in any kind of detail ... furthest man-made object out there is only 0.2% of one light-year ... or 1/2,000th of the way to the nearest star ... that took 50 years ... just a measly 100,000 more years to get to the Alpha Centuri system ... another 100,000 years to get back if and only if the inhabitants fill the tank up ...

Currently. FTL travel is theoretically possible.

Currently. FTL travel is theoretically possible.

And what theory would that be? ... more importantly, can it be demonstrated ... do you have an experiment in mind? ...

FTL travel is philosophically possible ... I agree ... but that doesn't make it true ... we will always be alone ...

Because life in the universe is extremely rare and limited. Which would be especially true for higher life forms. With that said, the universe is massive and it would be unlikely if we were the only beings that know and create. Why? Because the laws of nature are finely tuned for life to arise when the conditions for it exist and enough time has passed.

I was addressing AI ... Mars fulfills her criteria, does she not have an answer? ...

I agree with you ... and I personally blame our piss-poor technology ... no hover cars ... and no telescopes that can pull a spectrum off one of these exoplanets ...


... yet ...

General Relativity allows for wormholes that violate the Special Relativity prohibition.

Would you say the universe is mostly hospitable for life or mostly inhospitable for life?

None of us can answer that question right now. We don’t yet know rough for anyone to have a valid idea. Nonetheless, the key word in your post is “mostly”. It has been proven that “some” life exists in other places.

Sure you can. The answer is it's not. The vast majority of the universe is open space. Of the tiny miniscule sliver that's not open space only about 5% of that is visible matter like stars and other celestial bodies. The remaining 95% composed of unobservable dark matter (27%) and dark energy (68%).

So right off the bat we can know the universe is inhospitable for the vast majority of the universe. It's amazing how some people (not saying you) don't realize they have won the cosmic lottery. Hearing people cry about how bad their 1st world problems are makes me laugh.

The issue there is anchoring it ... it would be 200,000 years to get one end to Alpha Centuri ... and travel through a wormhole may well destroy any biology we're trying to examine ...

Do you have an experiment that demonstrates wormholes? ... and if I may paraphrase Fermi ... "Where are all the tourists?" ...

There's no chance of anyone or anything traveling through a worm hole or a black hole in one piece. Ain't happening. The issue is the curvature of space (i.e. gravity).

Of course there is no experiment, other than mathematical constructs. However, many items that we use on a daily basis at one time only existed in mathematical form.

I truly doubt that.

 

[San Souci]

There are billions if not trillions of galaxies in the known universe. Galaxy's, like the Milky Way. There is life out there. Even a small fraction means that there may be millions of planets inhabited by life in one form or another. But, we'll never know for sure.

Maybe BEES are a dominant race on some other planet

What kind of life do you mean?

Life as we know it? Or perhaps don’t know it?

Any.

A single cell organism. Anything that has cellular organization, metabolism, growth and development, response to stimuli, reproduction, homeostasis, and adaptation/evolution. These traits are used to distinguish living organisms from non-living things, though some exceptions and nuances exist.
