>was less nice. Then again, it might have been the lack of rowboat size comparisons.

or the fact that chocolate is probably not as explosive as fireworks?

​

I think they probably have more "no smoking" signs at the fireworks depot.

what is the comparison you're trying to make?

Wasn't it called an astro-tracker? Locked on to several stars simultaneously (all stars are motionless relative to each other).

I had to use a Periscopic Sextant. Manually calculate the assumed position of a body Observe the true position and plot fix on chart.

I even wrote a small program to calculate positions of stars, sun, moon, and planets. It fit on my Radio Shack PS1 with 1.8k of memory. I was in High Cotton.

Wish I had a Astro-Tracker.

I have eaten them regularly when they were available just because could get them super cheap and I was sick of potatoes. I did not bother to peel them before cooking, they come out of the peel easily once boiled. I have never eaten the peel.

The bananas themselves once boiled and peeled have the texture and taste comparable to potatoes or another savoury root starch.

Its not something I'd pay top dollar for or seek out, but it was fine for adding some variety to my carbs and cheap so why not.

I mean time slows down near a black hole due to the extremely strong gravitational field of the black hole. Given the theory of general relativity this is due to the gravity curving literally everything around it in a way that affects our ability to measure time and space.

So I mean technically things exist for a longer period of time than we can truly process because either we accept that there's a distortion and our technology hasn't advanced enough or that time is inherently slower there and things entering a black hole entered it long before we even know it entered.

To answer the latter question (someone else may have already answered it) "As black holes gobble up the matter in their surroundings, they also spit out powerful jets of hot plasma containing electrons and positrons, the antimatter equivalent of electrons. Just before those lucky incoming particles reach the event horizon, or the point of no return, they begin to accelerate. Moving at close to the speed of light, these particles ricochet off the event horizon and get hurled outward along the black hole's axis of rotation."
