Some of you fags are so narrow minded. So many people here are claiming, "Well we haven't been visited by them, and he haven't communicated with them, then where are they?" There are much larger implications and many ways to try and gauge why/where/when intelligent civilizations can/will form.

To do this, all we have to do is try to hypothesize what we would do as a species once we have reached a certain level of technological and scientific advancement. The Kardashev Scale is a good place to start. Consider the following:

>Type I: a civilization able to harness all of the power available on its planet. Earth specifically has an available power of 1.74×10^17 W (dominated by the incoming solar radiation).

>Type II: a civilization that is able to harness all of the power available from its home star. The Sun outputs approximately 3.86×10^26 W.

>Type III: a civilization that is able to harness all of the power available from a whole galaxy. The actual value of this figure is extremely variable, since galaxies vary widely in size. Power output from the Milky Way is estimated at approximately 4×10^37 W.

>Type IV: a civilization which controls the energy output of the visible universe; this is within a few orders of magnitude of 10^45 W. Such a civilization approaches or surpasses the limits of speculation based on current scientific understanding, and may not be possible.

Whirlpool Galaxy, one of the best views we have on another galaxy. The thing at the top is a smaller companion galaxy.

Is it possible that somewhere in the universe on a planet that inhabits intelligent life similar to ours that they could have a completely different number system that would still work perfectly?

Hey, /sci/

So recently I've been looking into going into University. Hopefully for physics because it's something I find really interesting. I'm just weary because my interests have changed a LOT in the past year (Doctor > Chef > Religious > Engineer > Video game programmer/3D modeler > Physics)
and I want to know what I'd be getting into.

Is there a lot of work? Well, specifically, really tough work? Because I like a challenge. I'm - I believe - pretty good at math, and I get science concepts really easy. I've learned about quarks, dark matter, antiparticles, etc. etc. and it all is something that I find very easy to visualize

I want to know what kind of careers there are if you graduate a physics program, and an overview of what your course was like, if possible.

The pizza we just ordered is here, so I shall return in a short while. Don't let me down, /sci/.
