Black holes don't emit light from inside the event horizon. Ouside, space is incredibly warped due to the high gravity. So much so that light can actually orbit a black hole which is why it's depicted with the glowing accretion disc - you're seeing light caught by the gravity, bent, and then thrown off because the orbit isn't stable. This leads to odd effects such as extreme gravitational lensing where objects behind the black hole sometimes appear as distorted images around its edges.

Interestingly, space and the light near it is so distorted near them that if you were to, from your initial perspective throw a ball straight at what you perceived to be the center of a black hole, you'd probably miss it entirely.

Anyway, to answer the question, it's possible for the black hole to theoretically illuminate Miller's Planet because of how light is bent around it. Some of that light will get thrown towards the black hole facing side.

My problem isn't with the time dilation, it's with the fact that the planet(oid?)'s gravity was only 1.3x that of Earth yet time was dilated to the point that 1 hour was 7 years. The math just doesn't line up.

Big disclaimer: I'm not a physicist. Those who know better should feel free to correct inaccuracies.

The difference is the reference frame. On the planet you feel the planet's gravity, you don't feel the black hole's gravity because you're in orbit around it, even though you're definitely influenced by it. The time dilation is caused by the black hole's massive gravity distorting spacetime in its surrounding area relative to other things, so the planet's gravity really has nothing to do with it.

Think of it this way - if I'm in a car moving at 100kph in the direction the earth is spinning. Technically from the perspective of someone standing still relative to the earth I'm actually moving at the speed of earth's rotation + 100kph. That's a little under mach 2, but to the person in the car it doesn't feel that way because these forces are constant. You are technically in a consistent freefall. along with the earth.

Yes, but the issue here is why would the time dil;ation on the surface be so vastly different to the orbiting spacecraft? They are both within the almost the same gravitation as related to the blackhole.

Are you saying that the surface experience of blackholeG+1.3G gives you this much time dilation compared to the orbiting spacecraft's blackholeG?
