No, this is simply not true. The only thing regarding mass and energy carried in the photon is the photon’s own energy. This is independent of the mass of the piece of metal. The photon can have pretty much any energy; you don’t mention the source of the photon, i.e. whether it’s reflected, comes from a transition, or is from thermal emission. But none of those mechanisms is dependent on the mass of the chunk of metal. E=mc^2 would refer to the mass or energy of the metal. This is unrelated to the photons being emitted. I don’t see how the HUP comes into play here; a chunk of metal is a macroscopic object and the uncertainties in position or momentum are wuite small, as is Planck’s constant. Nonsense. You can’t have more mass than energy, since E=mc^2 tells you the minimum energy content you can have. For an object at rest, they are equal. If it has more energy than that, it’s translational kinetic energy, which is not thermal energy. A hot object has more energy than an otherwise identical cool object, but it has more mass, too. Do you have the evidence or test that I asked for?

To be the same in all inertial frames means it’s the same everywhere. Not really a mystery. Right. Nope. Nothing like that is required. And if you are asserting this, you must provide evidence or a way to test the idea. But we already know that inertial frames don’t require a brain, via countless experiments where there was no brain in the inertial frame. Lorenz theory? Do you mean Lorentz? I’m dubious that a photon contains information about mass and energy of anything except itself. Looking at a rock does not tell you its mass. (there’s a movie where Henry “Indiana” Jones Jr. depicts this rather well) Never? Surely photons can penetrate the skull. Ever seen an x-ray of a head? Aside from the incorrectness I’ve pointed out, composite bosons exist. There’s hydrogen in the brain. H-1 is a boson. Which is still pretty meaningless. This sounds like you are saying the brain causes fermions to have half-integral spin. Brains do not predate the existence of bosons and fermions.

If that’s your take, you misunderstand relativity. The first postulate of relativity is that the laws of physics are the same in all inertial frames, which is why you can’t tell if you are stationary or moving, and why there is no preferred frame if reference. A consequence of that, and the invariant speed of light, is that various quantities, like length and time, are relative rather than being absolute. And this has nothing to do with brains. Muon decay rates vary depending on whether they are moving or in the lab. They don’t have brains. What does this bolded part even mean?

Compensation from working for someone else isn’t the scenario under discussion. My grad school time was subsidized by some government grants, but those were via the school, and in any event that afforded me the opportunity to get a good job and I’ve more than repaid that subsidy with the taxes I’ve paid over the years. A lot of government support (welfare programs, for example) is like that, but the give-and-take isn’t even when you get to the stratosphere of wealth. Musk’s companies got $4.9 billion in government subsidy as of 2015, so the number is surely bigger now. And that’s corporate; it doesn’t count the personal tax breaks that only the wealthy can get, and the tax cuts they’ve gotten https://www.taxnotes.com/featured-analysis/many-loves-elon-musk-and-incentives-won-them/2023/03/16/7g77f# The notion that poor people as a group are lazy is one of those zombie tropes that keep getting repeated even though it’s untrue.

One of the basic tenets of physics is that it’s the same everywhere - it’s independent of anyone’s brain. Physics works where no brains exist, and where no observers exist. The value of and invariant nature of the speed of light is important in many processes and interactions that take place completely independent of brains.

It depends on the specifics. Exactly as they behave when relativity in incorporated in QM, which it has been. https://en.m.wikipedia.org/wiki/Relativistic_quantum_mechanics

You seem to be projecting your ideas onto others. The propositions about the brain are yours. I haven’t seen anyone else make these conjectures.

What does “extremely non-deterministic” mean? While outcomes in QM rely on probabilities, wave functions evolve deterministically, and there is still cause-and-effect. The things in relativity that are deterministic aren’t in conflict with the non-deterministic aspects of QM.

Evidence or a way to test the idea are required. The brain has no impact on the fact that neutrinos basically (i.e. to first order) don’t interact with matter. It’s not a matter of processing the data - there’s no data to process if there’s no interaction.

But the converse is not true. The photodetector is not a brain, and yet it's an observer. A brain is not required. Evidence? All you've done is make an assertion. The brain has nothing to do with why we can't perceive neutrinos Absolutely not. ChatGPT is not a science resource. It's souped up predictive text.

A photodetector lacks a brain but can be an observer. A brain can do calculations. The issue is whether it’s doing calculations in all of these circumstances where the claim is made. Iterative feedback works, too. And while you can model such things with math, it doesn’t mean you are doing calculations. You throw a rock and it falls short of the target. The next time you throw it harder, and so on, until you hit it. There’s no quantification going on, it’s just iteration.

But Earth’s Hedean era lasted ~500 million years, so if that’s similar for other planets you don’t have habitable planets for O and B type stars. Other habitability issues arise as well - for hotter stars, the “Goldilocks” zone is farther away, but the far planets in the solar system are gas giants, not rocky ones like the inner planets. If that’s true elsewhere, it makes A type stars an iffy proposition.

I think you’ll find a few threads on our site that discuss this very topic. One common response is that an observer need not be a conscious being. There’s no connection to the brain. I’m leery of claims like this - that the brain is doing calculations. I’ve never seen good evidence for it. The arguments either lack rigor or the definition of calculation is diluted past the point of being meaningless.

You can look at frequency or wavelength but they are not independent, so it doesn’t matter which one. In your estimation, how long does it take for heat to pass through glass?Is it appropriately measured in nanoseconds, milliseconds, seconds?

But organisms from panspermia would be adapted to their home world. And the lifetime of the star ignores formation time of any planets, which would likely have to cool before life could survive on them.

I don’t know of any macro scale tests; CP-violation experiments are exceedingly difficult, and AFAIK seen only at the atomic or particle scale.

No, that’s 2/3 x 10^8 m/s (2/3) c is 2 x 10^8 m/s, since c = 3 x 10^8 m/s c is a constant. Light that has the same frequency must have the same wavelength Take a heat transfer rate and multiply it by a time interval, and you get the heat transferred. If the rate depends on T^4, the energy transferred will, too. I have come to the conclusion that you don’t have the math skills to analyze any of this. All of your errors here involve simple algebra. If you can’t get this right, there’s no point to the discussion.

! Moderator Note As Moontanman said, this must take place in another thread. The current thread is about cosmology

.03/3 x 10^8 ≠ .03 x 10^-8 The frequencies are the same. The wavelength are the same. Yes. Do you understand this is what we have been telling you and you keep denying? The radiative heat transfer depends on T^4 Thermal radiation near 300K is centered at about 10 microns. The wavelengths are the same.

c is 3 x 10^8, so this would be 0.01 x 10^-8 sec So that’s how you’re saying fast heat is conducted through the material? In a tenth of a nanosecond? Through 2 cm of glass? q in Newton’s law is an energy transfer rate, per unit area. They describe the same thing From the link I provided earlier “q is the heat flux transferred out of the body (SI unit: watt/m2)” (watts being joules/sec) which is exactly what the units are in the S-B equation, which you posted

Well, then, you do the calculation. How long does it take for heat to propagate through a material? I’ve listed several that are transparent to IR near room temperature. Assume the index of refraction is 1.5 How long does it take light of the same wavelength to propagate through the same material? (I had picked 2 cm for the thickness to make the calculation easy) No, absolutely not. Your result is very different from mainstream physics. I messed it, then. How does the Stefan-Boltzmann law give you a linear relation with T?
