Neil deGrasse Tyson: Are We Alone in The Universe?

Neil deGrasse Tyson explains the possibility of life existing elsewhere in the Universe. He explains where the elements that make up life on Earth come from. And how that has profound implications about the prevalence of life in the Universe. Certainly the question "Are we alone in the Universe" has got to be among the oldest, most fascinating and awe inspiring questions in science that remains unanswered. But Neil deGrasse Tyson paints a very interesting cosmic picture about life itself and why most astrophysicists indeed accept the probability of the existence of extraterrestrial life is high. At the very end he also has what he calls a disturbing and thought provoking question for the viewers.

So far, the only life we know of is right here on our planet Earth. Yet, there are compelling arguments to suggest we are not alone.
There are thousands of exoplanets that have been confirmed to exist in our galaxy and the likely number could be in the trillions.

Given how long life has had to evolve on Earth, it is possible that there are beings on other worlds that are even more advanced than we are. That would certainly have implications for our understanding of the origins of life.

A new study however, suggests that alien civilizations destroy themselves through progress, meaning our galaxy could be full of dead alien civilizations.

With a limited understanding of how life originated on Earth, and with so little understanding of what kind of life there is elsewhere in the universe, it is not too surprising we don’t know what we are going to find out there. But it seems very likely that other life will have developed in different ways to that which evolved on Earth.

So, are we alone in the universe? As Arthur C. Clarke has pointed out “Two possibilities exist: either we are alone in the universe or we are not. Both are equally terrifying.

We always assume that life on other planet are also sentient with advance technological advancement. They can be in a medieval era or even microbial.

And some of us still debating the shape of the earth...

Humans in future will laugh at us that we even questioned if there is life in the universe.

Aliens: oh look, they have telescopes

Growing up I sometimes ask myself the same question but Life is always a mystery.

Anything with Neil is awesome! He makes it fun to learn on how things work in the world and universe.

[Cosmoknowledge]

We are the universe being aware of itself.

I once said this in Chemistry even the professor brought this discussion to a conference at our college about organic life.

The correct title of this video should have been: "random guy speaking most of the time, featuring Neil degrasse Tyson"

You can be sure, that if we are not alone, all the kids in the galaxy are avoiding us because we are too dumb to play with.

[TheRealGzig]

If we aren’t alone in the universe, it wouldn’t be all that terrifying. Logically it follows that there would be life somewhere. Humans can learn much, especially if they meet our own intelligence or exceed it

Aliens: Aww, they're using electromagnetism to communicate...

[billyjohn]

Just remember life has started here on Earth (the most conducive place we know of for starting life) exactly one time in 3 1/2 billion years. That tells me that just because the conditions are right doesn't make it a certainty that life will spring up. Abiogenesis is something even the best scientists can't explain not to mention the huge jump from single cell organisms to multicellular. So although I do believe that there is most probably more life out there it is probably so far away that we might as well be alone.

[ufosrus]

Of course not! How could we be alone with trillions and trillions of stars?

[SamuelBuckleyScience]

But what if alien life is completely different than us? Like the argument brought up by Melody Sheep. Carbon is the reason why we are multicellular beings but what if life was based on silicon instead of carbon what would that be like exactly? I would love to see a video on that!

[reggienovenario]

What makes Neil so great is that he can break down what he's trying to explain on a level anyone can understand. Hes an astro physics translator. 😃

[jamolamo]

They are preparing us for full disclosure and I love it

Watching this types of videos made me spiritual ❤️🌍🧘‍♂️☮️👁
