Do Aliens Exist?

The universe is huge. That means two things: 1. there is probably life elsewhere, 2. It is likely too far away to have reached us.

Space is big. You just won't believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space. ~Douglas Adams

Thanks to Dr. Simon O'Toole for talking exoplanets with me! We also discussed the Drake equation but there wasn't really room for it.

the question is, is there intelligent life on earth?

[ashiljohn]

Thank goodness they didn't say something like "A Light-year is when we get more Sunlight in a year than Sunset."

[DarkKnight-uzos]

"A light year is a thousand years"

[jakeweberzwier]

"How many galaxies are there?"
"Probably more then 10"
"Actually there's more then 100 billion"
"Ok"

[MegaSnake]

"A galaxy is a sun and a moon, right?"
Even if you're thinking of a solar system, that's still VERY wrong.


"A light year is a thousand years, isn't it?"
I... just... It's not even... Ugh

[pxdnninja]

I understand not everyone loves science and space as much as some of us, but it blows my mind to think that some people don't know what a galaxy is.

[jasonjones-up]

"How many have we discovered?"
"Me personally? Six"


Damn what a flex

[koshka]

How can you be an engineer and not know a Light-year is a unit of length?
That is astounding to me.

[FPTanky]

i like how proud the dude at 3:20 is about his 6 exo-planet discoveries :D because that actually is a thing to be proud of

[RajithaSeneviratne]

Judging by the answers of these people, it's no wonder aliens don't visit us.

[MichaelMiller-rgor]

How do people not know what a galaxy is? Or a light year?

I can at least forgive them for not knowing what an exo-planet is.

For to answer the title, I wanna quote a line from one of my favorite book: "The universe is a pretty big place. If it's just us, seems like an awful waste of space." (Carl Sagan, Contact)

Lucky to find such dense participants. "What's a galaxy?.... Emm a sun and a moon?"
Very special indeed.

[philippheller]

you just found the reason why Aliens wouldn't visit us

[AydenEmpire]

Did you purposely interview people that lack the ability to think

[RafidW]

"galaxy is a sun and a moon" well there goes my will of living...

[mytmouse]

Aliens exist. They watched this video and laughed at those answers he was getting.

[you_just]

"How big is a lightyear?"
"I'd say about a thousand human years, yeah?"

[Hasake]

I like how Derek is so nice and doesn't laugh or face palm when these guys give completely wrong answers.
I guess he just understands that mistakes must be made in order for science to continue

[keithluvvadog]

Love your channel- thank you. Got to say though that this video does not discuss the extremely improbable likelihood of life arising at all - pretty important omission!
