Cats are cute and cuddly. They purr a lot. They bury their own poop, which is very considerate. They shouldn't be put in a box to die at the whim of some radioactive particle.
I think from now on we should all refer to it as Shroedinger's Rat. Or maybe Shroedinger's Banana Slug.
You have understood nothing. The phenomenon is real and one of the strangest and most spooky things in physics. It shows that it it possible to get a particle (in this case a photon) to interfere with itself.
No; YOU don't seem to understand the difference between an observation and an interpretation. It doesn't "show that it is possible to get a particle to interfere with itself." All it shows is that a beam of single frequency light passing through two holes and shining on another surface will produce a banded pattern on that surface. Photons "interfering with themselves" (whatever that means) is just one possible interpretation of the observation.
The physics community hasnt even explained Gravity fully and they are worried about another universe.
Correction: the physics community hasn't satisfactorily explained gravity AT ALL. Warped space-time does not explain why a shotput feels heavy in our hand. In the October 2003 issue of Discover, Michael Martin Nieto, a theoretical physicist at Los Alamos National Laboratory in New Mexico, was quoted as saying, "We don't know anything. Everything about gravity is mysterious."
OK; here's a force that supposedly emanates from all matter, yet has no identifiable power source, does not decay or diminish over time, and uses no fuel. Whatever happened to Conservation of Energy? The orbit of our planet around our sun is as close to a perpetual motion machine as we have ever seen.
And don't try to snow me with that old Work Function dodge. Physicists would have us believe that gravity never does any work. That it requires no work to keep our planet from zooming off in a straight line into space. That a boulder being forcibly held down on Earth's surface requires no energy. They say that, since w=fd (work = force x distance), no movement means zero distance and therefore no work, therefore no energy required. They modify the work function equation (which was never intended to be a "work detector") to explain that Earth being held in its orbit around the sun requires no energy since the earth is moving perpendicular to the constraining source. The modified Work Equation gives a zero result; therefore no energy is required.
What a load of crap! Go outside whatever building you are in right now and try as hard as you can to push it to the east for 10 minutes. Guess what? According to this logic, you have expended no energy! Oh, never mind that spaghetti feeling in your arms and legs. You've expended no energy because the building never moved.
Please. These guys don't understand/can't explain the most ubiquitous, fundamental force in the entire universe, and use flawed logic to "explain" it, yet expect us to fall at their feet when they come up with these inane theories. It's easy to find a theory that explains only some of the observations.

I've known a lot of people who liked math and science, but were utterly useless as thinkers.
Conversely, I've known a lot of mediocre thinkers who could have benefitted from the logic training that advanced math provides.
"Why do I have to learn this stuff? It's so hard, and I'll never use it in the real world." The blame for the second part of the complaint lies with math teachers. They cater well to the gifted among us, but do nothing to entice the rest of humanity into something that ought to be as joyous to learn as music.
As far as the first complaint, that math is hard, I can't help that. It is hard. So is music.
Calculus in particular and math in general should not be a grind. You cannot do well at it as long as you regard it as a dreaded battleground that you must cross in order to get your card punched. Instead, think of it as a hike over a mountain pass. Yes, it's hard work to trudge up those slopes. And yes, you long to rest in the valley that lies on the other side. But the view from up there is breathtaking.
And that's what calculus and higher math do for you; gives you a vantage point on the world that you cannot have any other way. It teaches you the language you must know to understand how the wind blows, how the waters flow, how the sun shines, how music reaches your ear, how the planets cycle through the heavens, and much more. Even the ebb and flow of such human activities as population dynamics and economics are better viewed from calculus' highlands. If you don't care about any of that stuff and prefer to remain in self-imposed ignorance, staring at your CRT day after day as you enter in column after column of meaningless data that no one is ever going to look at, looking forward only to the weekend so you can go kill some more of your rapidly dwindling supply of brain cells, thus temporarily forgetting your colorless, meaningless pathetic life, then so be it. Go with God.
One of my many hobbies is stained glass. Recently I made an icosohedron storage box using stained glass construction. I wanted a depth to the glass so each triangle is compsed of two layers; one of clear glass for the outside of the box and one of textured glass for the inside. In effect, I actually built two boxes. The triangular pieces that comprised the inside had to be slightly smaller that the outside pieces so it would fit together correctly, and tightly. I could not have built it if I did not know trigonometry. It is sitting on my shelf because I couldn't bear to part with it; a testament to the joy of higher math.
Pick up a book, my friend. Math and a strong vocabulary are the crucial building blocks of all other education. To focus solely on language skills and ignore math is to hough yourself.
