>If there really are so many other advanced civilizations out there, where are they?
You answered your own question: OUT THERE.
See, the universe is a HUGE fucking place. And of ALL the trillions of stars out there, we have only been able to transmit detectable signals to about half a dozen (ASSUMING target civilizations even have the technology to receive them, and are even listening). What are the odds that there is actually a civilization on one of those stars? Almost nonexistent. What are the odds that some other civilization out there that is trying to contact US is even close enough for us to hear? Almost nonexistent. That doesn't mean they aren't out there, SOMEWHERE. All it means is that we will probably not be able to know that they exist... well, not for a VERY long time, if ever.

Hello /sci/, I came here with a question.

Do any of you take adderall? For anxiety when having tests or anything important is coming up?

Thanks.

Pic unrelated. Or is it?
