Not exactly. First, a GPU can't run a pixel shader against EVERY pixel simultaneously. A typical screen might have about two million pixels, while GPUs max out at a few thousand concurrent 'threads of execution' i.e. it effec

Yes, the color of every pixel is ultimately determined by a shader program, but as you might expect it's more complicated then that. There is what is referred to as a graphics pipeline consisting of a mix of fixed-function hardware sta

You're right that there could be multiple things which separately explain the things that dark matter explains (not just the two you listed, but the others as well: gravitational lensing, galaxy cluster motion, etc). But the strength o

You're right. The Big Bang theory really only concerns itself with what happens starting at around 10^−43 seconds after the presumed singularity that started the universe. That presumed singularity is just a consequence of running Gene

No, the Rayleigh Criterion is still correct, you just have to consider the "aperture size" to be the size of the combined multi-telescope device (which would be the size of the Earth if the telescopes are on the opposite sides of

I totally agree that lockdowns are super expensive, and should only be used as a last resort, but I think you're missing the purpose of lockdowns. The purpose is not to save the lives of <however many people are dying right now>.

If you include the ejected mass, then momentum is conserved in that system. The ejected mass goes one way, the rocket goes the other. The momentum of the rocket is equal and opposite to the momentum of the ejected fuel. Not true for the EmD

The force cannot possibly depend on the drive's kinetic energy, because the kinetic energy is based on the velocity, which is relative to the frame of reference you use to measure it. If your frame of reference is the drive itself, the

When you do the math, in order to extract infinite free energy as per OP's argument, you have to get the drive up to a certain speed (think of a y=x line intersecting with a y=x^2 parabolic curve). The required speed depends on the per

It's pretty simple. You can use the known laws of gravitation and the visible distribution of matter in a galaxy to predict how fast stars at the edge of the galaxy should move. But when we do this we find that the stars are moving muc

Not really floating, since that implies a certain freedom of movement that atoms in a solid don't have. But otherwise you are correct, since each electron is a tiny magnet (protons and neutrons are also magnets but their magnetic field

Free protons (protons outside of an atom) have never been observed to decay. Protons inside a nucleus can of course decay, see: https://en.wikipedia.org/wiki/Positron_emission

Outside of Earth orbit, space objects become incredibly rare, and outside the solar system they are rarer still. There are much bigger problems to worry about, believe me. By the way, dark matter is likely passing through your body right n

That's a good point, but the fact that all Turing machines are equivalent (and the fact that the equivalence is purely mathematical, and does not rely on any laws physics) implies that computers in ANY universe would be similar to ours

You're assuming that movement properties are special, and that non-movement properties don't affect the environment until they are collapsed. This is not the case -- quantum mechanics treats all quantum properties in the same way

>Things in superpositions only becoming "set" after observation... that is just lazy evaluation. It's fun to think about. Lazy evaluation is generally used to defer some expensive computation until later. In this case, th

I'm not an astronomer, so don't take this as gospel, but I believe that large undiscovered planets are expected to be rare. Mainly because they would have had to form in the inner solar system (where all the matter was) and then

Yes, there is. Firmware updates must be digitally signed using Apple's private key. That means no one except Apple can edit out the device check, or indeed modify the firmware in any way.

Umm, you can have many macs with only a single GPU configuration - if they are all identical models. Similarly, you can have one copy of Lion and install it on multiple machines (AFAIK). There is nothing in their statement that proves tha

This is from October 2009 (yes, more than a year ago), when Mozilla blocked two .NET-related plugins because of a security flaw (with Microsoft's blessing, no less). As far as I know, both plugins were both unblocked within a week or so.

If you want to really understand the language, do what I did, and write a compiler ( http://jurassic.codeplex.com/ ). You'll learn about fun oddities, like why the lexical scope introduced by the catch block is different from any other typ
