Seth " they have been right under my nose for 70 years" Shostak. What a pioneer.

[FryskFS]

Seth was an inspiring teacher at university Groningen and he is still an inspiring speaker. You should invite him for a 2022 Lecture!

[TheBOUNCERCHANNEL]

Seth always cracks me up, speaking about such an important topic while ripping on the audience and mankind lol.

[soubhikmukherjee]

Seth is really intelligent. I love him.

[_FyldeFlyer]

I love watching Seth's presentations but come on, thiswas 8 years old when you first posted it !

[zapfanzapfan]

Seth is hilarious, I've seen it before but worth seeing again :-)

His book is good too.

40:28 "Sagan figured there's a million broadcasting societies. If he's right, then by 2015 we might get one." - It is currently 2019. :(

[UtraVioletDreams]

All those little arguments/jokes. Fantastic, it really gets the point across.

[mrquiff]

If there are 2 trillion galaxies, and every galaxy has billions of stars we can’t be the only intelligent species .
There probably is intelligent, communicating species out there but too far away to know, how

[anddontcallmeshirley-]

He's a great speaker, very engaging.

[davedave]

How could they possibly keep it TONS OF PEOPLE HAVE COME FORWARD.

[gariusjarfar]

No one in science ( at the top ) makes a modest living.that's why we have Seth as the guru.

[minuterepeater]

Though I dont Always agree with him; his lectures are never boring.

[thatdutchguy]

He's the sales guy for SETI by now.

[capitalistrevolution]

From 2010! I wondered about the low number of planets found and none earth like.

[remekficko]

Perfect proportion of information and humour!

Wouldn't aliens communicate by quantum entangled systems that preclude finding a radio signal. If there is a reason in physics why this isn't likely please enlighten.

[mjmcrae]

Which would you be more likely to find in a solar system with two Earth like planets? Planetary commerce…or planetary war?

[geoffreywright]

The story of the early mistakes in the observation of Mars is very interesting.

Questions for SETI:

- What is the maximum distance of stars that SETI is currently probing?
- I've never heard Dr Seth Shostak talk about the fact that we are probing in the past for extra-terrestrial life. It would be nice to know what a prominent scientist like Dr Seth Shostak has to say about that.

As an example, if SETI detects a signal from a solar system that is 500 to 10, 000 LY away, that would mean that the level of technology of the civilization where the signal it is coming from is currently (advanced enough to send signal + 500 to 10, 000 years of additional evolution). If we add that technology tends to follow an exponential evolution, the implications for that civilization would be very scary for us. That civilization would necessarily be much more advanced than us. It would change humanity''s self-perception to something else forever!

In a sense, it's a blessing that such signal has NOT been found yet! Is humanity ready for this?
