I looked up the explosions on the surface of Jupiter at around 2:45 and then followed a YouTube chain for the better part of an hour. I eventually watched videos on black holes, the upper dimensions, hypercubes, those zen magnet things, and somehow wound up watching how it's made videos. Gotta love the internet
LOL. Since you brought up the Jupiter comet impact here is something to consider. The comet that impacted on Jupiter (Shoemaker Levy 9) was originally about 3 miles in diameter before it broke up into numerous pieces shortly before hitting Jupiter. It was literally torn apart by Jupiter's massive gravity. It broke up into something like 20 separate pieces and left a trail of impact scars on the Jovian "surface" (for lack of a better term). The largest of those impact scars was larger than the planet Earth. That was done by a comet that started out at about 3 miles across and broke into over 20 pieces before hitting the largest gas giant in the solar system.
Now consider scientists are saying the comet that may impact Mars is roughly about 31 miles in diameter (10 times bigger than Shoemaker Levy 9), and couple that with the fact this comet will more than likely hit Mars still more or less intact due to Mars rather weak gravity. Factor in that Mars is a rocky planet and is roughly only half the size of the earth. This impact will be like nothing we've ever seen. The entire surface of Mars will be totally transformed.
