Who can look out into space and not ask the age-old question: Are we alone in the universe? Astronomers have already identified dozens of planets beyond the edges of our solar system which could be like our own Earth.
Join astrophysicist Lisa Kaltenegger, who is the director of the Carl Sagan Institute at Cornell University, as she explains the different methods astronomers use to detect exoplanets orbiting distant stars, what these planets would need to support life, and how Earth and its range of species might serve as a Rosetta Stone-a key to detecting the existence of extraterrestrial life.
This SciCafe program took place at the Museum on November 1, 2017.

Yes! There's other life out there but we're not on the,same level. They're either more advanced or way behind. In space what kills us kills them. Great distances in space is your friend or enemy depending on your intentions.

You need modern technology to tell you we aren't alone?! If the universe is infinite its silly to think we are the only ones here. We havent found life? Can you reach into the infinite universe and check? No? Stop treating our galaxy like its special and rare

@raidermaxx2324 6 жыл бұрын

White Out they are treating our galaxy like any scientist who implies critical thinking, would.. because if our scientists just started making wild claims, like “there is life in the oceans of Europa! I know it for sure! It has to be” and there was no evidence to back this up, not only would that scientist lose whatever job he/she was currently holding, but they would be nothing better than trump or one of his surrogates, spouting fake news, and lies.. there is a reason why, people have to be skeptical, and it’s based on the scientific method, invented during the Renaissance era, which has worked for us so far. There will come a time, I’m sure, that people will be able to claim that life on our planet is but a drop in the bucket, in the cosmological zoo that is our universe, but until we find another planet besides our own, with a second genesis, and not life brought on by panspermia, but real, alien DNA, we have to continue on the course, whether it upsets you or not.

of course we are not alone ... you would have to be self centered to think otherwise. Life is probably not anything like earth though... so what we are looking for is probably wrong. Further, an advanced civilization would be smart to use neutrinos to communicate since they can go through all types of matter unimpeded. So, we should look for neutrino signals not em signals. em signals are too noisy with many sources.

What makes me confused is Why we always want to colonise mars? Why always mars of every planet? It seems like the conditions of this planet is mot particular suit for us? All the documentaries and Hollywood movies always focusing on mars? There is even a program in NASA to make it to mars and colonise?

Sir, you have been deceived. Do not believe the propaganda from your government and agencies like NASA. Mars has a blue sky for a reason. It was colonised by people from Earth many thousands of years ago. Their descendants are still there. Yes! yours is not the first technological civilization to have evolved on Earth, it is in fact the last! But times have changed and it is time for the truth to come out.

Yet another one that poses the question relative to the “universe” instead of the “galaxy.” Believe whatever you like about the universe, which is truly vast, but we will never detect signs of intelligent life in galaxies other than our own.

We don't even know if there is other life in our solar system. We are still trying to detect the bio-signatures of the atmosphere of Venus, our sister planet just a few million miles away. We are still uncertain of its atmosphere and whether trace gasses are bio signatures or not. We have landed probes on Venus and we have detail imagines and yet we still don't know about Venus. Yet we are going to make huge assumptions from the spectral analysis of few rays of light from a planets atmosphere light years away?

Fermi-paradox solution? Evolution of intelligence may depend on small social groups, as we observe in human evolution, and in Earth's most intelligent birds, wolves, dolphins and apes. Groups of a dozen to a couple of hundred individuals, seem to be a prerequisite for developing any kind of higher intelligence. If that is a general principle, then no Kardashev 2 or 3 civilization can ever exist. In fact, large coherent civilizations may only be a short-lived artefact, of an intelligent species lack of technology to roam free. And as soon as such technology is realized, civilization will disintegrate naturally. I mean, if you owned a UFO, that provide everything you need for free, and lets you travel anywhere in the universe ... Would you stay in your apartment? ... Would you keep your job? ... Probably not. Rather than living and corporating with strangers, in a competitive and stressful environment, most people would prefer to travel with friends and family. 'Tuning out' is a strong inclination, due to our evolutionary roots. An inclination currently only suppressed by our need for goods and convenience. If indeed intelligence only evolves via small social groups, then such inclination must be true for any aliens as well. And, the Fermi-paradox actually suggest that this *is* a universal principle, just by demonstrating a lack of large detectable civilizations in our universe. Technologically mature civilizations may simply disintegrate, and small groups of individuals spread so thinly across the universe, that detection becomes impossible. This could be our faith as well.

I'm pretty sure we are not asking the right question, whenever we ask whether there is life on other planets, let alone so-called intelligent living things (it may be a good question, although not an original one, I think it merely reflects our lack of knowledge and narrow-mindedness, and the fact that we are unable to imagine other highly complex entities outside the realm of living organisms (that includes all human-made things, too, of course) with which we are more or less familiar with). Sure, it is highly likely that there are similar life forms on other planets that are similar to Earth, but there may be some other extraterrestrial things on other planets which we wouldn't even call LIFE because these things would be very alien to us and radically different from everything else that we currently know about - strange manifestations of matter that we can't even imagine yet with our present knowledge and understanding of matter and the universe. Just think about it, simply put, living organisms on this planet are really just highly complex manifestations of matter. Who knows what else there is outside this Earth...?

Yes we are alone. If 1 out of every 5 stars had an earth like planet and if 1 in a million of those had intelligent life, then there would be technologically advance species everywhere we look. We would have found them by now and they would have found us by now.

Life form elsewhere. Compare why nature has left this thing uninteresting and meaningless? All over the universe, the distance, access or other barriers and incapabilities of life form prove, the nature has left this thing meaningless for life, just like, think how uninteresting and meaningless is the life form even here in your neighbourhood, cities, countries, except for overpopulation, redundancy, crises, diseases, envy, etc etc. Even if we got a hint of life form elsewhere, it would be biological only and no different, which is right here on your own planet abundant. ☺☺☺ Just an opinion. No offence. (Press Alt+1 to smile ☺)

Adam didn't become a living soul until God breathed life into Him. And if God withdrew His Spirit man would wither and die. The Lord, who stretches out the heavens, who lays the foundation of the earth, and who forms the human spirit within a person... I have not met anyone who hasn't heard of Gods message of salvation given through Jesus. As in these last days God has spoken to us by His Son. Gods salvation is forever - the present creation along with our bodies has been subjected to decay by the creator Lift up your eyes to the heavens, and look at the earth beneath; for the heavens vanish like smoke, the earth will wear out like a garment, and they who dwell in it will die in like manner; but my salvation will be forever, and my righteousness will never be dismayed. For those who believe in the Son and go to Him for life they will be raised with new bodies not of the dust of the earth. And God will provide "See, I will create new heavens and a new earth. The former things will not be remembered, nor will they come to mind.

Are WE alone in the universe? A universe that encompasses so many things beyond our knowledge we can't count them all. There are black holes, countless stars and planets. Would this universe really therefore have Donald Trump be the most powerful man in it? Doubtful.
