More perplexing than that are black holes for sure, especially now that they found out recently the supper massive black holes, the ones up to 100 Mil mass of our sun, are actully growning at about a 10 perent faster rate than the galaxy! Also, the concept that when an opjecdt is so big and and has such mass it can literally no only warp space, but can slow time. It is just mind boggling. Last thing before I bore you, haha, are pulsars. A star that has collapsed to about a 7km diameter ball that is so dense 1tsp ways around 2-300 tons. Depending on the sequence in which the star burns through all its fuel like from like hydrogen to nickel, depends on whether is collapse into the ignigma that is a black hole, or compresses its self into a pulsar. Which can spin at about 30K rev a sec or some nonsense like that. Shooting gamma rays out like a light house upwards of 65 light years! I promise, Ill stop now, nerd switch off.
