Mr Skeptic

I think its accurate to say the center of the Big Bang is 15 billion years ago.

Basically, blood is passed through a "sieve" to keep in the proteins, then of what goes through the "good stuff" is reabsorbed, and the rest discarded. This mechanism means that the kidneys can discard just about any chemical, even those you've never been exposed to before.

Then it follows that the Apostle Paul couldn't have been a true Christian. As you say, to be a true Christian he would have had to have studied all the religions of the world and also the atheistic scientific explanation, before he could be a true Christian. By your standard no one can truely believe in any religion. Or does that standard only apply to atheists? Well all of them must be liars, with the possible exception of one of them. Oh, and you forgot to include Dawkins in your list. One of the religions has to be right because you're sure one of them must be right? (And you don't know which one!?!) If I'm sure their all wrong does that make them all wrong, or does it only work that way for things you are sure of? Sure there has, some of the gods do have testable predictions. But tell me, how many gods do you believe in? Do you believe in invisible pink unicorns? Do you hold a double standard, where someone must disprove your god before you can not believe in it but someone must prove the existence of any god you don't believe in already before you will believe in it? Pardon me, but I prefer to base my beliefs on things that have been proven accurate, not things that have no evidence for nor against them. For people who have no purpose in life, choosing a purpose in life provides one. Sure you can choose a religion when you choose your purpose in life, but the purpose in life given by the various religions seems empty and undesirable to me. I think anyone who believes in a religion cannot reach spiritual fulfillment and become truly humble. But tell me, why is it you think that people need to believe in a religion to reach spiritual fulfillment and become truly humble? Or is that yet another thing you believe because you have not seen any evidence against it?

Well first you should look up the word "paradox".

Well one of the major components of your weight is water. You can lose a lot of weight by getting dehydrated, and gain it back by drinking water rather than calories.

Well I doubt astrologers would go for switching your sign by half a year if you were born in the southern hemisphere. On the other hand, most of the world's landmass is in the northern hemisphere, so on average it should still have some effect.

As usual, your idea has some awesome but impossible parts, and some crappy parts which may or may not be possible. In short, your idea is impossible, and if it were possible then a better device could be made by disregarding some of the extra restrictions. You can copy/paste this to the various other suggestions you've made to date. For this one in particular: Impossible: Complete combustion of molecules. Material completely transparent to EM radiation, eco-friendly or not (if only due to impurities, and yes same goes for only a certain band of EM). Non-explosive explosive ignition as described. Impractical: The radiation being from the flame itself rather than a proper blackbody emitter. Limiting the oxygen to only what is stoichiometrically necessary for combustion, since that would result in additional unburnt fuel and some unreacted oxygen, rather than slightly more unreacted oxygen and a more complete combustion. Use of dirty gas, rather than having it cleaned and the non-fuel components removed for a cleaner and more efficient flame. Wasting helium as described. Practical: Using radiant heat transfer.

Well I know that with training some paralytics can move a wheelchair just by thinking about it instead of using their hands. http://www.gizmag.com/toyota-wheelchair-powered-brain-waves/12121/ Does that count?

There's no paradox, the robot will do as it was programmed to do. Since a programmer dumb enough to write such a program with the intention of the robot reaching the wall probably won't worry about the capacity of its numbers, it is likely that due to either measurement error or rounding error the robot will reach the wall eventually.

I can move objects like my arm with just a thought! Does that count?

And this, I think, is what explains why your machine will not work if the fluid is directly touching, since then the flow would be several drips per second, it could run a whole day's worth of dripping in about a minute.

The tilted axes affect what parts of the world get how much sunlight. The key here is that the axis always points in the same direction as the earth goes around the sun. It's easiest to see if you imagine the tilt being 90 degrees, so that the northern and southern hemispheres would be entirely in the light all day long during their respective summers and entirely dark all their winter. In fact, that is what it is like at the poles even for our small tilt. But for most of us our tilt just means longer days during the summer and shorter during the winter, but we have a day/night cycle every day.

I gave you another explanation as well. Feel free to read it before dismissing it. It cannot be but that the explanation of why it won't work is because it violates the laws of physics, in your case both the laws of thermodynamics and electromagnetism. See, this is what I mean about you not understanding how capillaries work. Capillaries can only pull when empty. Anything pulling the fluid out of and more into the capillaries is the same thing, the functioning is the same as with a tube -- suction is stronger than capillary action. It can only be the magnet pulling the fluid into the capillary (indirectly via suction from pulling some fluid out), and the capillary cannot contribute to this since it is already full. Anyhow, you can't go back to the original state while extracting energy. If it is not some reservoir draining, something might be happening to your fluid. Incidentally, how many drips per minute is your device?

Because I prefer dealing with small, pointlike particles than with vector fields of infinite extent.

Try looking in a thesaurus: http://thesaurus.com/browse/stealthy

Gravity, or any force in general, can convert stored potential energy to kinetic energy, or can do the opposite, depending on whether you're moving along or against the force. So you can store energy in a spring by pushing or pulling it, and release the energy again by releasing the spring. Any time you release potential energy you cannot move the system back to the original state without putting in at least as much energy again. Also, any time the net force acting on an object is in the direction the object is moving, the kinetic energy of the object will increase, and anytime the net force acting on an object is opposite the direction of motion, the kinetic energy will decrease. For example, if you throw an object upwards against gravity, its kinetic energy will be decreased by the effects of gravity.

Ozone protection is not necessary for life, just a few feet or water would work as well. Also ozone and even the oxygen necessary to have the ozone layer are very nasty for living things, and yes that goes even for the ones that need oxygen to live. Yes, and again water helps even more with this, both as a greenhouse gas and due to its high specific heat, and I'm sure that evaporating, condensing, freezing, etc also help transferring heat. Another cool thing about water is that it is less dense frozen than liquid, unlike almost anything else, so that it provides and insulating layer on top rather than freezing all the way to the bottom.

I've heard of this sort of thing, but I doubt their $30 a barrel. Of course if it is true I'd gladly watch them make a fortune undercutting the oil companies. (but maybe they mean to compare with the price of a barrels of crude needed to make only that one component). Not until we get electric airliners...

Sometimes it is convenient to do that, and people do this with all sorts of things. It's called "anthropomorphizing". However in the rules of physics there is not much room for optional behavior: In quantum mechanics, Gell-Mann's Totalitarian Principle states: "Everything not forbidden is compulsory." (the corollary is "Everything that is not compulsory is forbidden.")

Some people think that the universe is not logical. If you and the universe disagree, I think I know which one is right! However as D H said, non-determinism and true randomness could fairly be considered not to be logical.

Well if that is so then that would be a violation of the laws of physics. Well, both answers are that it violates the laws of physics. But generally I go with the explanation that doesn't involve the first/second law of thermodynamics, I consider those redundant. Yours would violate the first law. The first law is essentially the same as saying that all fundamental forces are conservative forces, so that if you move an object in a loop there is no gain nor loss in energy. Magnetism and capillary action are both conservative forces, so your machine can't work. Friction is not a conservative force (an object loses energy when moved in a loop), but the lost energy goes to heat and no energy is lost, since friction is built from conservative forces. I will suggest an improvement to your machine. Instead of capillary action and dripping, you should make a closed tube, with magnets on either end and filled with your ferrofluid. This eliminates the energy loss from dripping and the associated turbulence, so that instead you'd have low friction laminar flow, and also increases the throughput of fluid to be moved. This also as a bonus eliminates the problem of your not being able to understand how capillary action works. Can you tell why my improvement to your machine won't work? It's the same part that won't work with your machine: you don't move from the strongest part of one magnet to the weakest part of the other, not for both magnets.

"You don't have a Soul. You are a Soul. You have a body." -- C.S. Lewis If you switch brains from one body to another, you'll become the person whose brain you have, which is yours. You'll have to relearn all the "muscle memories", some information is stored in other parts of the nervous system than your brain, and in any case the details of your body are different so you'll have to relearn it all, even how to walk. Some of your personality might change, much like your personality might change when you get a certain job or a million dollars or any other possession, except that with a new body you would have different hormone balance.

That's rather impressive, if you mean it going in a circle rather than dripping from some reservoir. Dripping is not very good for conserving energy/low friction. Well that's missing the part where it drips back to the first magnet.

As another example of conflict between morals in various religions, Islam forbids alcohol and some sects of Christianity require actual wine for communion, not to mention worshipers of Dionysus. Satanists have yet other morals based on their religion, if you think the other example was just about details. In the Bible god was always complaining about the Jews turning to the other gods and doing evil deeds, like sacrificing children to Moloch. Pick any two religions, and they will have different morals anywhere from the level of details to core principles.
