>The galaxy should be full of alien radio signals...

Why?

The thing NOBODY ever talks about, is the strength of the signal necessary to be received lightyears away.

Sure, our TV broadcasts from 1950 are 70 lightyears away now. But are they strong enough to be received by anybody? Apply the same reasoning to any other civilisation. People always kinda assume that radio signals are binary. Either there is one or there isn't.

I have a question for all of you who think interstellar travel is

Do you think we reached the end of physics?
As in: Do we know everything there is to know about the laws of the physical universe?
Do you think there is nothing at all we might have missed, missunderstood or simply not encountered yet?

And if you do, what makes you think that?

okay

So, basically anything mainstream science says is right?

I have a question though. We all know looking back at history, that many scientific results (and thus theories and assumptions) have been proven wrong by later data. Which domains of science would you consider susceptible to such revisions in the future? Do you see anything in the current understanding of the universe that could literally be turned upside down by later discoveries?

Surely you don't think we reached the end of scientific discovery.

Okay, let's pretend building this shit was even possible?

what about this?

Yeah, let's trap all of this crap in a giant ball and see what happens.

Are we still trying to live inside the sphere?

>Is he the smartest man alive?

What exactly does all the shit you listed do? Are there practical applications of what he has done?

If not he might as well have gotten all the achievements in World of Warcraft.

Is there a way to determine logically and/or scientifically what you should do with your life?

What you should spend time on?
