Dissecting a cathode ray tube television
Heck, yeah they do! Experienced repairmen usually won't even touch one until it's been sitting unplugged for a week or more. There can definitely be enough charge in TV capacitors to kill you.- ibcnunabit

Graduate Does a photon experience time or space?
I'm finding that two of my posts out of four on this topic are missing--why is that?- ibcnunabit

Graduate Does a photon experience time or space?
Oh, I think there's *something* special about light. lol Even if it's not relevant to the double slit experiment.- ibcnunabit

Graduate Gravitation: curved spacetime or a force?
Gravity is a phenomenon that we just don't fully understand yet. We are familiar with "what it does", the laws governing its consequences, but we don't understand exactly how. There are contradictions in the current state of the two theories, but many physicists (not necessarily a majority)...- ibcnunabit

Graduate Can spacetime exist without energy?
Even with virtual pariticles there would be no NET mass.- ibcnunabit

No, it would be red shifted because it lost energy in the interaction. Although I'm thinking (I may be wrong) that you probably wouldn't really call it red shift, because the original photon was absorbed, the interaction happened, and another (different) photon was emitted with the energy not...- ibcnunabit

Projectile Launched from Moon: Altitude for 3/4 Speed
More precisely, an unconfirmed source says 1.62631, but I haven't done the calculation or found corroboration--but it's close enough to the approximation I do know that I don't doubt it.- ibcnunabit

Graduate Does a photon experience time or space?
If you interpret the question as whether the change of position or time elapses from the photon's perspective, no, it doesn't. This has interesting consequences, and I believe is one of the prime reasons for many of the peculiarities of light as seen from our perspective in which distance and...- ibcnunabit

High School What are common signs of a faulty wheel hub bearing?
Momentum is best described as a mass's resistance to changes in velocity such as would result if a force were to act on it. It's a fundamental attribute of matter that you experience every time you're riding in a car and experience a hard, sharp turn. It's what makes your body want to keep...- ibcnunabit

Graduate Is Spacetime Truly Smooth or Discrete?
I don't think anyone really knows, at this point. It hasn't been proved either way, but we do know that if it's quantized it must be a pretty fine-grained quantization. Reiner Hedrich, for one, has written a number of papers on the idea of quantum spacetime. If quantum mechanics is...- ibcnunabit

Graduate What makes schrodinger cat quantum?
I agree that the oscillations ARE real, from our perspective. For the photon there is no time for an oscillation to occur. (Aha!) But we see what we see, and depend on it. The oscillation may be a product of a tiny spatial dimension or some or spatial or dimensional aspect of reality that we...- ibcnunabit

High School Is Time's Speed Just Wild Speculation?
I understand the sense of the question, but within a given frame of reference, the question is meaningless. If time "sped up" or "slowed down", it would do so for everything in that frame, and would be indetectible. Also, speed is a concept that's derived from time, so to try to build it into...- ibcnunabit
