Some scientists believe a black hole is a wormhole to alternate universes. This could be true, since black holes suck in and white holes pull things out of it so there is a likewise chance they are connected- but how would we know? Black holes, once you get close enough, due to their immense gravity, will stretch you to your death which is a process called spaghettification. But I may have found a way to figure if this theory is true once and for all. Maybe there is a material or metal that can obscure this process. There's a small probability it could actually work, but there is still a small slither of chance. With the right engineering and combinations, of course. Some metals that could be used are gold, silver, copper, aluminum, iron, nickel, and titanium. Some materials that could be used are cloth, linen, and wool. But there is still the issue of the warping from the inside of the black hole and the force of the push from the white hole.
