Somewhat related, would seeing a superluminal ship help us figure out how to do it, too?

So this is something that's rumbled around in my head for a while and I'd like to see if I can get an answer here but I'm not sure I can word it correctly. Quick disclaimer, this is all 'as I understand it' not factual or even researched by any means so it may all just be a bunch of bullshit. Essentially the questionI have is this:

Time passes more slowly the closer you get to a black hole. If a civilization was at war with another civilization, wouldn't the civilization that could travel closest to a black hole always come out on top? The closer you get, the slower time passes so you could accomplish more in the same relative time. Is there something I'm missing? If we went to war with another civilization, rushing toward a black hole (not into it) would buy you tons of time to develop weapons/people/whatever and they would always come out on top.

Does my question make sense?

I've seen this question asked on Reddit multiple times, and the comments usually say that sunflower oil is not healthy because it contains high amounts of linoleic acid, HOWEVER, all of them were in the context of the high amounts of Omega-6 in the American diet which doesn't apply to me... so I would like some answers with less American diet bias.

With the hurricane approaching and now some projections show it passing over Vegas could the hurricane fill lake Mead? Is there enough rainfall in a hurricane to fill that large of a lake.

Light is made of photons, so how do mirrors put the photons on a route that follows the law of reflection?

I have read that since photons have no valid reference frame they don’t experience time. They move through space at c so no time value, in essence.

But space and time are the same in relativity and space obviously affects photons ie they experience eachother. Photons redshift over distance and time, as the most obvious example.

So how is it that a photon can’t “experience time” yet it experiences space? Why isn’t redshifting over X ly considered experiencing time already?

I’m just a layman so I’m having a hard time reconciling a photon not experiencing time due to not having a valid reference frame; but that just doesn’t affect its deal with space? It gets a valid reference frame in space then?

New research has found that a disease-causing fungus—collected from one of the most remote regions in the world—is resistant to a common antifungal medicine used to treat infections.

So I just saw the YouTube video someone posted that showed nuclear reactors starting up, and the first thing I noticed was that they all glowed a very bright, pretty blue. I'm probably an idiot, but I was honestly expecting green, because of many years of dramatized depictions in popular media.

These are probably dumb questions, but:

1. Why is it blue? As in, what's actually glowing in there, and why do we see it that way?

and

1. Why do all the movies and comic books and video games go with green instead? Where did that come from?
