Is it okay to attend lectures if you are not a student? I'm really interested in physics but can't afford going to a university. I'm considering going to some lectures in my spare time. Would the professors notice/mind me being in their lectures? Have you ever done it?

It will be like pic related.

>Just curious, does #2 and #3 not address this. Can you remove the fungacides or will I need to find wild morning glory

which will cause nausea
but that's a side effect you may have to weigh the risk of being effected by for the trip

So light from the red part of the spectrum is less energetic than from the blue part, right?
Light as it travels large distances through the cosmos is redshifted due to cosmic acceleration, right?
So light loses energy travelling, but where is that energy going?!
