We're Probably Not Alone 😳 w/ Neil deGrasse Tyson

[frogman-]

I love listening to Dr Neil Degrassi, he’s so intelligent & makes things easy to understand

[ShawnGlenn.]

It’s just simply impossible only one tiny planet such as ours is the only planet that has intelligent life out of literally billions to trillions of galaxies.

[pablojimenez]

Bro. This is guy is brilliant. He's right in so many ways. And the crazy thing is that the Universe is still expanding til this day 😳

[Nerry-G]

It takes a very intelligent man to make a very complex thing look so simple by conveying a mental pictoral understanding that an average person can connect to.

He's a genius!

Einstein had great knowledge...but wasn't able to communicate his knowledge in simple terms for everyday people, except his scientific community around him.

Give this man his flowers!
Anyone disliking him for doing what he does should take mind-soul check in the mirror... there's something wrong!

[DaveCase-jk]

We're made of common stuff but we're still precious

[illnigma]

Ok if we aren't alone can you even imagine what the others would look like? They could literally be 47ft tall, 86 heads, 467 eyeballs. I guarantee, whatever is out there, does not look like us by a long

[talos]

That's the one thing I wish would happen before I die. The discovery of life on another planet.

[SWExplore]

We are definitely not alone. Of that I am 100% certain.

[hagailema]

He is absolutely right, universe is mind blowing deep.... and we've explored less than 0.0005%

[coolcat]

I love your videos. Keep up the good work

Professor Brian Cox summed it up for me when he held a handful of sand in his hand and said that if he let go of the grains of sand that there is no reason why those grains of sand couldn’t fall and form a perfect small Sand Castle. However the chances of each grain of sand falling in its perfect place to form this Sand Castle are immeasurably small. Each grain would have to fall in exactly the right place, the chances of that happening are trillions and trillions to 1 but it’s not impossible.

What gets me tho about the possibility of life elsewhere in the universe is that we think it must be on a planet in the ‘Goldie Locks’ zone and that the planet MUST contain water amongst other things. ALL life on Earth past and present needs water, carbon, oxygen etc. Life has evolved on Earth and has evolved with the chemical make up of Earth. Couldn’t life have formed on a very different planet with very different and deadly conditions to those here on Earth, after all some life on Earth is animal life, breathes oxygen and expels carbon dioxide in very different environments.

What does life on this planet look like?

ET maybe closer than we think, we just assume that all the building blocks for life on Earth are the same building blocks for ET to exist. Has science thought that maybe that isn’t necessarily the case?

Does life even need a planet with a surface, why can’t there be life on that gas planet that doesn’t need a solid surface, does it need an atmosphere? Maybe or maybe not.

I feel like this guy is my friend! ❤ Neil 🍺

[Nyx]

Why doesn’t this channel have 8b subscribers?

[elementkingaming]

In every galaxy theres at the very least 4 type 1 civilizations. The question is. Are they all alive at the same time??

[lesliebrown]

All day I could listen to him. So smart so interesting.

[eckobrown]

It’s sucks in a way to be born today knowing what we are going to miss out on in the future

[dexhazedmv]

Never a word about Always what and not how. Always what and not how

[TheBluBalls]

Aliens ignore us like we ignore a crackhead shitting outside a Starbucks 😂

[SchwabGames]

Earth is the only place right now we know to have life 100%. We shouldn't take it for granted, no matter if we're alone or not.

[lewisjbh]

what's funny as a young scientist he argued like many against thid idea.... nice to see logic coming back
