Is there life on other planets? What say you?
Lot's of guesses and discussion about this from many experts.
On the one hand we have the overwhelming statistical data saying yes.
200 billion to 2 trillion galaxies.
200 Billion Trillion stars
2 trillion planets on observable space.
Stats say there must be more life and more than likely intelligent life.
However it takes a long time to develop life to our point and the universe is supposedly not old enough for widespread life.
Also time also suggest that some parts of life may have come and gone already.
What say you all? Life elsewhere? Intelligent life?
Now if our rules of physics are correct and hold up and there is no fast than light travel and no way to harness theoretical things like worm holes, there could be intelligent life elsewhere but simply too far away.
Opinions? Theories?

I'm very convinced about much the same things you're saying.
Of course there is both life and intelligent life in other places of the Universe.
However, I do not for a second believe that Earth has ever been visited by intelligent aliens, not now and not in ancient times.
I do think we should be careful though, and NOT send any strong radio signal messages directed at close stars. It might be better to be quiet.

I do think we should be careful though, and NOT send any strong radio signal messages directed at close stars. It might be better to be quiet. I don't think it matters. Too late to consider hiding. We've been saying we're habitable for billions of years now, and we ourselves have already sent signals that we can't take back. That cat's out of the bag. *** Is there life on other planets? What say you? I think the vastness of the universe statistically means life exists elsewhere. Whether it's hit any sort of sapience yet who knows. The universe is young, very young if you think of it in "child rearing" years. 13.8b ain't that much when compared to the Degenerate Era. All depends on that entirely random chance of molecules aligning into something that'll work as life in a suitable medium. That takes time, we can look at our planet and guesstimate given how fast we progressed, but that's a narrow view to gauge everything. However, there are just so damned many opportunities out there that if it can, numerically it must.
I don't believe Earth is a magical haven of life and our entire universe exists as a barren wasteland. I also don't think we've been visited by ancient aliens, and if any new ones were to take a look it wouldn't be to the tune of UFO-mania, crop circles, and anal probes.

We've been saying we're habitable for billions of years now, and we ourselves have already sent signals that we can't take back. That cat's out of the bag. Well, there should be a signal/noise problem, as long as we don't direct a radio emission straight at someone. The latter is what I wanted to warn against. I haven't done the math, but the limiting problem for both military radar and infrared scanners is that the energy quanta gets so spread out with distance that it cannot be distinguished from natural noise. I would assume the same applies to radio waves in space? Since there is a 'target' though, there is the possibility of building very large directional listening antennas, and aim them at our sun. That doesn't solve the problem, but moves the feasibility s couple of magnitudes.

So cool, just saw a short tv news story about them making mini satellites made out of wood. All the components are stored inside no antenna or anything on the outside becasue signals can go through wood.
Also burns up properly on re-entry. Just cool, lo tech over high tech,

I think this video visualises gravity and space-time surprisingly well.
What if we could see Spacetime? An immersive experience

Now if our rules of physics are correct and hold up and there is no fast than light travel and no way to harness theoretical things like worm holes, there could be intelligent life elsewhere but simply too far away. Opinions? Theories? As you say, the numbers pretty much guarantee it. No matter how unlikely or rare life is, it has hundreds of billions of possible planets over almost 14 billion years to arise. It could be that life is pretty common, but intelligent life or technological civilizations are really rare. Or maybe technological civilizations all eventually self-destruct due to e.g. nuclear armageddon, catastrophic climate change, etc. There are lots of possibilities, but I'm still strongly on the alien train: its not a question of if we will discover life on another planet, but a matter of when. We've been extremely limited in our ability to look for life on other planets- for a long time the only exoplanets we could see were gas giants like Jupiter, smaller terrestrial planets orbiting in the "habitable zone" of its star were just too small and dim compared to the star and the larger planets- and are only recently having the technology to actually look for the types of planets that are the most likely candidates to harbor life. So cross your fingers, it could literally happen any day now (or not for a long time, we'll have to wait and see).
