Superfluid liquid helium defies gravity and penetrates glass at absolute zero

Absolute Zero - the ultimate extreme, a place so cold that we know it does not exist.

At this temperature fluids defy gravity and the speed of light can be decreased to 38 miles per hour !

Superfluid states of Helium-4 or Helium 3 exhibit many unusual properties such as zero viscocity.

The superfluid liquid helium appears to penetrate glass and defies gravity at absolute zero.

speed of light

if nobody has been able to reach a state of absolute zero, then speed of light at absolute zero cannot be determined. if people have come close finding absolute zero and have found that the speed of light changes with temperature and are doing math to determine the change in velocity of light and trying to determine what it would be at when at absolute zero, then they should not use mathematics to determine what it COULD be. for all we know, the speed of light could rapidly increase as we reach absolute zero, if there is even a such thing; and it could be unexplainable.

supefluids defying the laws of gravity

people say that superfluids (gasses such as helium) brought to nearly absolute zero can defy gravity. we have no evidence of there being a state of absolute zero so therefore nobody can say that anything can become something else such as a superfluid; at nearly absolute zero. when people say that superfluids defy gravity by "climbing" the side of a beaker or any object, they are incorrect. in order for any fluid; whether it be a "superfluid" or just a liquid in its state of fluid, this fluid is needed to be present for it to "climb". in the infamous video where the superfluid appears to either fall through the bottom of the glass beaker or "climb" the sides of the glass beaker, the fluid or superfluid in this case is needed to be present on the tops of the beaker. this is not the superfluid defying gravity, it is simply the fluid chaning from a gas to liquid state rapidly while still rising. if these people who suggest that the liquid is defying gravity and just simply climbing the walls of the beaker, then the superfluid would be able to just begin to rise in any situation not only in the beaker. please give me feedback on what you think. i am only 17 so i havent had as much time to do research on this as many people have, but i feel i am correct or atleast on the track of proving myself correct
