The Singularity

    Most scientists agree that black holes have a singularity, a point where gravity (or the space-time curvature) reaches infinity (actually, it only has very strong gravity. Click the infinity link if you want to know how). But, the problem is that they also agree that the laws of physics break down at the singularity. To avoid this situation, scientists have created varying solutions to this, from portals to other universes, to black holes actually hosting universes. I, personally, have my own theory*. That the singularity doesn't even exist.

    "How is that possible?", you might be asking. Well, in my 'Is Infinity Possible?' post (if you read it), says that infinity in a black hole isn't possible, only extremely strong gravity. Then this theory would work with the other one because both have the common ground of black holes don't have singularities. But there is a problem. If black holes don't have singularities, and lets assume it isn't a portal to another universe, or actually is hosting a universe, then in a (spinning) black hole, wouldn't all the matter just fly out? This may seem like a dilemma for any theories saying black holes don't have singularities, either black holes have a singularity or they don't exist, but this can be solved easily with my theory. And now the suspense is over. Here it is.

Levitation: How It Works

     Levitation is the stuff of science fiction. And scientists have been studying how to do it for a long time.  And I think that I found a way to turn levitation: science fiction, to levitation: science fact. If you want to know how levitation works, and know about a machine that can theoretically levitate, read this article about levitation.

    So what is levitation anyways? Well, anyone who watched a sci-fi movie knows that it is lifting an object without letting you, or a machine touch it, or putting engines of any form that propels the object into the air (in sci-fi movies, the levitating object usually has an aurora of light around it). So now we know what levitating is now. But how in the world can we achieve levitation?

    Levitation with magnets can possibly levitate if we first, put a north and north magnets, one above the other. But the problem is if the magnets are the same size. As most people know, when you try to put a circular magnet one above the other in the same fashion I have mentioned, they will fly off in different directions (usually the one in the middle of the air). This is because the upper magnet, in a certain degree, has to tilt. Then, there is more pushing force on one side, and the magnet tilts in the opposite direction, and gravity and the opposite magnet will free it of the opposite magnet’s grasp, then it will fall on the surface you used for your experiment. And even if the upper magnet didn’t tilt, it will still fall to the floor or table or chair, etc. That’s because the lower magnet has a degree of error, therefore, producing more push in one place than another, and you know what happens. It falls. But what happens if the upper magnet was smaller than the lower magnet?
