Most is electromagnetic, but some wireless technology uses sound waves.

How is it that you are claiming that “the LHC consumed lots of money” and you apparently don’t know how much was spent?
-
Is it? Show your work. It doesn’t, because photons are massless. They do have energy, though. Conservation of energy trivially tells you this. Again, show your work.

What is gamma factor of object, which is falling into black hole?

What’s ambiguous about “30% of the speed of light”? -
Yep. Misplaced the reaction under discussion..

A neutron decaying into a proton does not produce a photon; you get the neutron, proton, positron electron and neutrino antineutrino. Fusion reactions, though, can involve excited nuclei and nuclear de-excitations can produce photons. Also particle-antiparticle annihilations, as well as acceleration of charged particles, in addition to the electron (atomic) transition.

koti has been banned since his return only showed that his desire was to post in bad faith and stir the pot.

! Moderator Note Your previous discussion on causality was shut down for lack of evidence. All you've done here is re-state the hypothesis. Under the guise of discussing the aether.

Was efficiency the goal? Availability was probably the goal. But since efficiency affects profit, I'm sure some effort was made on nuclear plant efficiency. Solar cells are much more efficient than the ones we had in the past. Wind turbine systems are probably more efficient as well. Some research projects are small, others are big. It depends on the research. I've been on papers with 30 names on the paper, and others with 4 or 5. LHC and other accelerator collaborations are large out of necessity, since there are a lot of "moving parts" to those efforts.

Relativity of Time does not Make Sense.

Relativity of Time does not Make Sense.

This isn’t what relativity says. If this alien is 100 LY away, they see Bob as he was 100 years ago, because it takes 100 years for the light to get to the alien. Relative motion will mean they will disagree on how much time has elapsed, but under no circumstances does relativity say that the past can be changed. -
That’s all? The sun emits almost 400 yottawatts (which comes after zetta, which comes after exa, which comes after peta) And the sun is very close, since the emitted power per unit area drops off with the square of the distance. If you posted it here, we could read more about it.

If there was anything classified, there’s a good chance it would be declassified in 2027. 50 years is a common horizon for that. If it dud not, it must have bypassed that parabolic reflector, meaning it must have had an even larger amplitude.

It’s far-fetched in that there is no scientific basis provided for it. Since there is no physical basis for the portal, I don’t see how you can say it’s safer. You are proposing a comparison to fictitious systems. Do you understand that this is not science? -
Because you asked “Are you saying they are fixed from start to finish?” Now you admit to knowing that I was not. One wonders why you asked the question. No. You can’t tell what the property was before, since you can’t tell identical particles apart, and/or there was no known “before” property. In parametric down-conversion, for example, the photons are created as entangled. There is no “before” state. You’ve not shown an example of a system that has a “before” state that could be identified.
-
Of course they do. It’s because they receive signals from different directions. The issue is that they could not tell which horn got the signal, and which was the background. http://www.bigear.org/Gray-Ellingsen.pdf “Ohio State recorded the difference in intensity between the two beams, but not the sign, so there was an ambiguity in which beam the emission was detected.”
-
On what basis do you claim this? Surely the scientists know where the reflector was pointed, and thus the possible direction of the source.
-
Are you incapable of determining whether or not I said that? Or that I’ve repeatedly confirmed that the states are undetermined? I guess reading comprehension is one of the issues here.
-
Not sure how that changes things. Newtonian gravity doesn’t have a mechanism. GR has warped spacetime. Quantum gravity would have an exchange of virtual gravitons. How do you test which one is the “true” form? How do we know it’s not invisible pink fairies?
-
Models describe behavior, and can only be tested by comparing with observed behavior.

The drawing isn’t the shortcoming here. You haven’t presented anything that meets the level of rigor we need.
