Unresolved mistery: What is the speed of Gravity?

Photons do have momentum. It can be demonstrated with a radiometer. Yes, radiation will cause an acceleration, but radiation falls off as one over the distance squared. So as you get farther from the Sun, the intensity of the radiation falls. So there is a limit to the acceleration that can be achieved.

The solar wind is not radiation. It is particles, protons and electrons. When the particles reach the Earth they interact with the Earth's magnetosphere and caused the aurora.

No. That is not what it means. E=mc^2 is the rest energy of a mass. Rest means not moving.

The energy of a photon is E=hf where h is Planck's constant and f is the frequency of the photon.

For objects that are not photons, the energy is E=(1/2)mv^2 where v is the velocity of motion.

The temperature of a particle is E=(1/2)mv^2 where v is the rms speed of a gas. The temperature is also E=(3/2)kT where k is Boltzmann's constant.
Temperature is a measure of the kinetic energy of a particle.

Heat is a change in thermal energy. Changes in thermal energy occur by collisions which can increase of decrease the rms speed and hence the temperature.

Heat transfer occurs by conduction, convection, or radiation.

What is interesting, and hypocritical, about your statement is the use of the words "plasma mass". Gravity is an effect that depends on the mass of the objects. Plasma temperature does not depend on mass. So if light bending depends on mass you are describing the classical definition of gravity.

You are talking about refraction. The atmosphere beyond the surface of the Sun is too rarefied to cause that much refraction.

Energy is conserved, always. Matter is not.

Your beliefs are totally irrelevant. And you clearly have no clue about the experiments I referenced.

Pseudoscientific beliefs in "negative planes" won't save you.

Throwing out terms like Software Defined Radios is meaningless to a discussion about gravity. SDR uses FFT, mixers, and filter to demodulate a signal.

if photon has momentum, why laser beam cannot move a flame? if photon has momentum, why is light mill not spinning/moving in hard vacuum?

what is photon? where it came from? how it carries momentum?

before the solar wind reaches earth, why protons and electrons do not form into hydrogen atoms?

what is energy? what is rest energy?

what is photon? what frequency of photon? is photon vibrating? can you prove it?

Gravity holds trillions of tons of water upside level on our "ball" - while a minuscule gnat flies above the same water...

Wake up.

Gravity holds trillions of tons of water upside down- level on our "ball" - while a minuscule gnat flies above the same water...

Wake up.

matter transforming into matters, what else?

if you think matter can transfer into energy, by nuclear reaction, that is a mistake.

if you think energy can transfer into matter, by science story, that is a mistake.

nuclear energy is the same as chemical energy, both are stored within charged particles within atoms.

chemical energy is from releasing the bonding force between electrons and proton/enertron ball, nuclear energy is from releasing the bonding force between proton and enertrons.

this is too deep for you, before you understood the true structure of atoms.

if you can prove matter and energy is interchangeable, please share it.

welcome home, flat-earther!

threesome?

OK boy/girl. Now you are being a little bit gross over here.
I don't call names to anyone here, never.

"irrelevant", "pseudoscientific" and "meaningless" are an attack to someone who is just writing his thoughts. And an attack on thoughts by playing them down is one of the lowest and cheapest ways to make a point in an exchange of ideas.

FIRST: I started this thread 2 weeks ago looking for a subject that could be controversial. It went well, even when several times, postings were way off topic.

SECOND: You are not following the path of tought in the post that snapped you! I'm bringing the subject of SDR and DFFT here to PROOF that the ANALOG WORLD of the mathematics is flawed because it needs negative axis to WORK! If you don't get it, then go back to reading books and rethink things.

Without negative planes, integro-differential calculus doesn't work, OK? Specially with domain-transform tools. If you make the inverse transform of a Fourier function in the frequency domain, you obtain a function that covers from NEGATIVE infinite to POSITIVE infinite.

This is a SIMPLIFICATION in order to obtain CAUSAL functions. (i.e.: the response function of an impulse going throug a filter is CAUSAL, because the output has a DELAY regarding the input. If you use ONLY the POSITIVE side of the transform (impossible to do with analog math) then the output happens BEFORE the input, OK?

I cite SDR and DSP as a proof that engineers don't care about this flaw. They only uses the POSITIVE plane in the DFFT world, so theoretically output precedes the input signal. They don't care and the devices works anyway.

THIRD: Before saying that something I write is irrelevant, go and read about how to be a didactical person and not a hard core nerd who blasts others quoting "heavy stuff" gibbery without flexibility.

Did you teach to a class a technical stuff in your life? If you did or if you do, you have to have SEVERAL WAYS to explain the same thing, USIN ANALOGIES, ok? Several ways!

The ability to explain the same thing in several different ways, using analogies, is not for any random teacher. It takes flexibility and a good base of knowledgement.

FOURTH: If you know something about DSP and electronics, open a thread about it. I'll met you there to discuss the subject with knowledge, and without offending the other with mean words.

I called you no names. I was discussing your arguments.



Your statement was “I believe NOTHING WILL WORK!”. Use of the term “believe” in that context in science is irrelevant. Science is evidence based.

And if a statement is pseudoscientific and meaningless, it is not an ad hominem attack. If you do not understand that something is pseudoscientific then I suggest you actually take a course in science and not rely on YouTube videos.



In science, the topic is not controversial

[link to www.newscientist.com (secure)]



I am attempting to correct incorrect knowledge about the scientific process. Science is important to me and I think it should be properly represented when people, who are without any scientific background, are discussing it.

You have not proven that mathematics is flawed. You have proven your understanding of mathematics is flawed.

What you are really trying to say is not “negative plane”, but imaginary axis. In creating solutions to simple quadratic equations such as x^2 + 5 = 0 it is necessary to introduce the imaginary number, square root of minus 1. It is a standard, and well tested process in mathematics. The history of complex numbers goes back to the 16th century. Complex numbers work quite well in solving numerous problems. It is clear you have not taken a course in complex numbers. They have a simple geometric interpretation.



Integro-differential calculus does not use negative energy planes. Integro-differential calculus is just the use of an integral and derivative in the same equation. It is used in control system all the time. Your car computer system uses integro-differential calculus. You get integrals and derivatives in the same equation if you have a capacitor and an inductor in the same circuit. It is how resonances are created.



You are confusing the time domain and the frequency domain. The results of an FFT puts the solution into the frequency domain and there is no violation of causality.



Discussing SDR and DSP is a red hearing introduced to create a straw man argument. And yes, the devices work because of the understanding of mathematics, not in spite of it.



Already said this. Using “belief” in an evidence based system is irrelevant.



So making things up and not understanding when you are being corrected is not inflexible? Got it.

And we see who is using ad hominems now.



Yes. Daily.



But the analogies have to make sense. I do not just make stuff up because I do not know better. My analogies are well thought out and I explain any shortcoming in the analogy.



It takes knowledge, not knowledgement.

I often have to restate things using different words because learning styles for students are different. So what is your point again?



You started talking about DSP. Not me. And you discussed the topic incorrectly.

I do not think they understood some thing this simple.

OK. I've got a clear picture about who you are now.
You are a person that can't stop from being agressive in your arguments and you have to resort to the downplaying thing every time when you snap over something that you don't like.

I knew a few persons like you, in person. They respect me and don't dare to question what I say before they really think if there is a chance that I might be right. In real life, it works as a charm, and I never had a problem with those who think they OWN the knowledgement.

I also can tell that there isn't a single bit of humour and wit, as you can't tell the difference between a joke and a real statement. For instance, you don't get sarcasm and you are unable to tell if someone is trolling you, like I do over here at will (it takes intelligence and a good sense of humour).

One more thing: I'm almost 63 years old. I started University when I was 15, got an Engineering Degree by 21 and two Masters in Telecommunications and Information Theory by my 23 birthday.

I can walk back and forth on every body of knowledgement regarding mathematics, statistics, clasic physics, quantum physics, technical software and almost EVERYTHING on telecommunications. I wrote more than 20 thousand pages on technical stuff for my students. My last handbook on telecommunications has about 980 pages (three years ago). I've wrote more than 250 thousands line of code (technical) and constructed with my own hands several instruments, a computer clone, a rack with general purpose DSP subsystems to work on sound, speech and front end transceivers. There are so many more other things I did in the last 45 years that I don't recall now.

When a keyboard knowledge warrior like you start chatting with other "virtual person", I sugest that you spare a bit of doubt about WHO REALLY IS ON THE OTHER SIDE. Maybe, and I don't want to hurt your feelings, there is someone smarter than you (sorry) that plays you at will as I do.

Do you like fishing? Do you know what a bait is? Do you smile? Do you take yourself seriously? Stop this now. It doesn't worth the effort. You can't beat me, as I'm a master on games like theses.

I will not reply you paragraph by paragraph. It's not worthy. Now, STOP. Go back in this thread and READ what you wrote and what other people wrote and, PLEASE, wonder if your behavior really is the right one for an intelligent person (and you are one).

Goodbye. No hard feelings. I'm past them.

The real unresolved mystery is, why doesn't OP know how to spell 'mystery' correctly?

Gnat and gravity should shake something up, so anything that has little weight as still flies, does not lose direction or balance.

gravity is a function of mass/density and velocity, hence with no mass (post explosion) no gravity effects

I don't know, because I can't hear myself as I am TYPING IT!!

So, a typo? Maybe. A misspell, no way. Google "mystery" to find out who is right.

English is my second language and I don't master it, neither I show off that I do.

You, as an english speaking person, should wonder WHY, after 14 pages NO ONE NOTICED THE ERROR ON THE SUBJECT!

It should say UNSOLVED, not UNRESOLVED!!

Unlike you, I have not resorted to ad hominem attacks.

And no, I do not believe you. I do not believe you are an expert in DSP. I do not believe you have multiple degrees.

And, despite your fake broken English, I recognize you for who you really are. The poster formally known as Anonymous Astrophysicist and half a dozen other names. You keep getting banned and reinvent yourself with a new persona.

And now you will say the same tired thing about not knowing who AA is.

Now, this is interesting! Faraday, Gauss, Maxwell, Edison, Tesla and so many others in a single video:

Gravity does not exist.

OK, buddy. PEACE!!!




I formally invite to you, if you ever come to Argentina, to an ASADO with EMPANADAS appetizers and good argentinian wine.

A good food with friendly talk is the best thing in the world to settle differences.

wiseguys make typos

just in case

no google? no wiki?

This is weird! I search for "gravity proof" on YT and I found this vid. There are many others.

Watch the water flowing uphill!
