New Theories / Re: Gravitational Arm

However, once one spiral arm had been frozen by gravity force to the other galaxy

It isn't. Gravity isn't freezing anything in place here. It's like saying something in free fall is frozen in place. It's not. This tidal tail is a temporary structure.

New Theories / Re: Gravitational Arm
« on: 14/11/2022 05:36:03 »
I'm highly suspicious that this thread is going to be about material which you have had previous threads locked over. So let's get straight to the point: what is your "new theory" here? Keep in mind that if you start making the following arguments, this thread will be locked as well:

(1) That dark matter doesn't exist and that anomalous galactic rotation curves are caused by the gravity of regular matter alone.
(2) That gravity can be used to create unlimited energy.
(3) That it's the natural tendency for objects in orbit to move away from the body that they are orbiting without energy input.
(4) Any other physics-defying proposals you've made before.

So take caution in how you proceed. I will go back and look at your previous threads to check if I have to.

New Theories / Re: A Proposed Experimental Test of My Gravitational Time Dilation Equation
« on: 24/10/2022 22:10:03 »
Quote from: MikeFontenot on 22/10/2022 18:46:58
I have previously shown that the exponential version of the gravitational time dilation (GTD) equation (first given by Einstein in 1907) is incorrect, because it is inconsistent with the outcome of the twin paradox.
I think the rest of the scientific community would have noticed after a century if Einstein was wrong about something as simple as special relativity. The error in your demonstration was pointed out. You continue to assert this despite the errors being identified. This is a good deal of the reason why Kryptid moved this post to the lighter-side of the forum.

Pay attention to the peer review.

Quote
In Einstein’s 1907 paper, Einstein stated that the GTD equation is R(g) = exp(g L),
You forgot the τ in the equation, which is important. The equation (in natural units) is something like δ = τ•exp(g L) where δ is the remote duration change, the amount of age change of a hypothetical stationary twin, stationary relative to accelerating reference system ∑.
Einstein did not in any way suggest that equation was relevant to a gravity situation, so calling it a 'GTD' is just plain wrong. The equation is applicable to what is essentially a Rindler field (although in 1907, Rindler was still a long way off). What you call the 'GTD' is not applicable to the twins scenario (which for one thing doesn't involve gravity) because the Earth twin is not stationary in ∑, so the equation wouldn't even work in a situation where the turnaround acceleration rate is finite.

Quote
According to the Equivalence Principle, we can then also say that when there are no gravitational fields (i.e., in a Special Relativity scenario), two clocks which are initially unaccelerated, and which are separated by a constant distance “L”, and which are then simultaneously accelerated with an acceleration “A” (in the direction of their separation), then the rate ratio “R” is   R(A) = exp(A L).
You omit frame references here, making your statement misleading. Relative to inertial system S (Einstein's designation), two clocks which are separated by a constant distance L, and which are then simultaneously accelerated with a proper acceleration “A” (in the direction of their separation), then the rate ratio “R” relative to S is 1 since they have identical motion in S. Their separation in S remains L after any amount of time. This is effectively Bell's scenario with the string that breaks.
The same is true if both are accelerated at constant coordinate acceleration relative to S.  R remains 1 in S and the clocks remain synced in S. This fact is independent of the acceleration curve so long as the two curves are the same.

On the other hand, relative to the rear of an accelerating rigid object (designated ∑ by Einstein), the separation L in ∑ will remain constant, but the proper acceleration at the rear clock will be greater than at the lead clock. It is in this scenario that the R(A) = exp(A L), but the acceleration is not 'A' at the lead clock, so your specification of both of them accelerating at 'A' seems unclear at best. In ∑, both clocks are stationary so there's no coordinate acceleration at all. Their respective proper accelerations are there, but  they're not identical (*).

Quote
Note that for constant “A” and “L”, the rate ratio “R” DOES NOT VARY WITH TIME.
True only for constant proper acceleration. This isn't true for constant coordinate acceleration (relative to S say). You should be clear when screaming assertions like that.

Quote
I showed in [in another paper] that the above exponential equation is inconsistent with the outcome of the twin paradox.
Yes. I pointed out the error you made. You ignored that and continue to make this assertion.

Quote
Specifically, if the traveling twin (he) changes his velocity instantaneously at his turnaround, the exponential equation says that the home twin (she) will be INFINITELY old after his turnaround.
Again, it says no such thing. As you're written it (specifying R(g) as a rate ratio), it merely says that relative to the twin turning around with infinite acceleration, a distant twin (stationary relative to ∑) ages at an infinite rate, but for zero time. An infinite rate for zero time is undefined, not infinite. That says is that the equation cannot be meaningfully used for a finite impulse with zero duration, and not at all for the twin scenario where the Earth twin doesn't remain a constant distance from the travelling twin.

Quote
Section 3. A Proposed Experimental Test of My GTD Equation
...
That way, if the leading particle is ageing faster than the trailing particle, the leading particle will (on average) decay quicker than the trailing particle, which might be observable.
The relative decay rates would be a function of the frame in which that time is measured. Your 'test' description doesn't specify that frame, but in S (the frame of the accelerator), both samples will decay at the same rate regardless of the level of acceleration. If your theory predicts otherwise, you have a problem, but in the absence of a frame reference, your prediction is ambiguous. Either way, relativity predicts what will be measured.

New Theories / Re: Can black hole be electrically charged?
« on: 28/05/2022 07:03:24 »
Quote from: hamdani yusuf on 28/05/2022 06:08:22
If electrons are continuously shot into a black hole (from beta radiation or electron gun), will it be electrically charged?

Yep. That's conservation of electric charge. There is an upper limit of the amount of charge that a black hole can carry (for a given mass, that is), though. For reasons that I do not understand, adding electric charge to a black hole causes the formation of an inner horizon in addition to the outer event horizon. As more charge is added, those two horizons get closer together in size. If the charge was sufficiently large, the horizons would merge (canceling each other out) and you'd end up with a naked singularity. Creating a naked singularity is currently thought to be impossible by general scientific consensus.

Quote from: hamdani yusuf on 28/05/2022 06:08:22
Can the charge be sensed from outside, i.e. the Coulomb force?

Yes. That's actually the mechanism that prevents a black hole from becoming "over-charged" and creating a naked singularity. As the black hole becomes more charged, the repulsive force makes it more and more difficult to add extra charge to the hole. In order to overcome that repulsion, the charged particles must be injected with increasingly high energy. Since that energy is the same as mass to a black hole, the black hole's mass also increases along with its charge.

Quote from: hamdani yusuf on 28/05/2022 06:08:22
How does the black hole mass affect the strength of Coulomb force, by modifying the distance from an outside object?

I have to admit, I don't know the answer to that one.

New Theories / Re: Is the Sun alive? Does It have consciousness?
« on: 02/12/2021 18:39:35 »
Quote from: puppypower on 02/12/2021 15:50:07
If you look at the various definitions of life, such as;

 Life is the condition that distinguishes animals and plants from inorganic matter, including the capacity for growth, reproduction, functional activity, and continual change preceding death., the phenomena called fire checks all the boxes. Fire can metabolize, grow and even reproduce via sparks and radiational heating. It is connected to continual change from its birth to its death; forest fire. It is lowering free energy and increasing entropy just like life. Life is type of dynamics more than it is a type of thing.

Fire is not the conventional way we look at life, since we think in terms of protein, DNA and  water, but since fire does check all the boxes for most definitions of the state called life, then one may ask can fire, such as the nuclear fire of a star, evolve its unique state of life, to states that we might called fire's version of consciousness? It will not look like we expect it to look; ego centric, but it would be able to adapt and even resolve issues as it metabolizes and changes with time. it may be more instinctive looking; animal impulse, than willful and choice based; uses the laws or instincts of physics.

With organic life, the state called life; checks all the boxes, does not appear without water. Dehydrated cells are not alive even with all the organics in place. Water is what makes life possible. If we add the water back to dehydrated cells everything works and al things now coordinates for the state called life. No other solvent can replace water; it checks all the boxes.  Does water have a type of consciousness since it was key to the "natural selection process" at the nanoscale, that led to the organic chemical states associated with life.

Life would not appear if water was not mediating; natural selection at the nanoscale, and integrating everything within the cell. If we add it all up, it appears that fire and water are both alive, but since they cancel each other, they define two divergent directions for life. Water by canceling fire helps make the life of fire more manageable; metabolism

The military make very good rail guns.
(so do some amateurs).

They design them using the known laws of electromagnetism.
And, since they work, those laws must be correct.

So anything you are saying must either agree with those laws- in which case it is redundant, or it disagrees with them, in which case it is wrong.

So, which is it?
Was your post pointless or wrong?

Physics, Astronomy & Cosmology / Re: Are photons relative?
« on: 23/03/2021 01:07:28 »
Quote from: jeffreyH on 22/03/2021 22:39:04
What you are missing is the location of the photon at any given instant is not relative to anything else. All other particles are relative to the photon. That is why the speed of light is used in relativistic gamma. This is the absolute maximum speed limit. As an absolute it can't be reached by massive particles. Since everything else's velocity is measured in relation to this absolute then the photon must map to an absolute frame.
Photons do not define a frame of reference. The laws of physics are the same in any inertial frame of reference, but not in a photon frame since photons always move at c relative to any frame.  They cannot be at rest.
Photons do not define any particular 'frame' since while they may all have the same speed, they have very different velocities.

You seem to have stopped asking questions.
If you are asserting these things, then this topic belongs in new theories. If you're not asserting them, then read the replies and don't suggest that things are being missed.

« on: 19/04/2020 23:31:42 »
Quote from: OP
First digit for each instance
It seems that your calculations are using Base-10 numbers.

That makes it rather anthropocentric (octopi would use Base-8, and starfish would use Base-5 numbers;computers count on their fists).

If you have discovered some fundamental mathematical theorem or some fundamental property of the universe, then it will work in any number base.

The universe is not anthropocentric (but humans are).

Quote from: OP
Pi x Pi 350 times
To represent Pi in a computer, you need a computer with an infinite number of bits. These don't come cheap.

If you are only interested in the first Base-10 digit of Pi, you can get away with double precision floating point

To multiply Pi x Pi 350 times, you are effectively calculating something like π350, which is a around 10174.
- according to my calculator, π350 is 10174.00245..., which almost looks like a round number in Base-10 (but it isn't)
- according to my calculator, π351 is about π x 10174, which almost looks like π in Base-10 (but it isn't)

If you want to take this further, you will run into the limits of double-precision floating point, which is about 10308
- And very small errors in the least significant bits grow to become quite significant
See: https://en.wikipedia.org/wiki/Double-precision_floating-point_format#Double-precision_examples

For this type of numerology game, you need to use multiple-precision arithmetic, which can give you millions of digits (leave it running overnight on your home computer).
- You can get these maths packages from a number of vendors (I think Wolfram Mathematica is one; gnu have a free one for programmers).

New Theories / Re: Has a logical presumption misdirected science down a cul-de-sac?
« on: 19/02/2020 23:51:50 »
I want to point out that I detected a mistake in the calculations I did in reply #130. I ended up with 4.92117 x 10-11 (slug•ft2/s2•A2)/m, but I should have replaced the meters with feet. When I make this correction, the answer ends up being 1.499973 x 10-11 (slug•ft2/s2•A[/sup]2)/ft. This new number is still different from the imperial gravitational constant (3.4397 x 10-8 ft3•slug-1•s-2).

Likewise, the vacuum permeability of 9.2685 x 10-7 (slug•ft2/s2•A2)/m would be more properly stated as  2.8250387 x 10-7 (slug•ft2/s2•A2)/ft

New Theories / Re: What is the relationahip between mass and charge?
« on: 16/02/2020 22:53:09 »
Quote from: puppypower on 16/02/2020 21:13:04
One relationship between charge and mass, based on the preponderance of natural data, is positive charge appears to prefer to merge with the heavy mass; proton. The negative charge prefers to merge with the lessor mass; electron.  There is more of these two change-mass configurations in the universe, than the alternative, where charge-mass is reversed.

Since when did charge merge with anything? Protons and electrons automatically come with their charge. Also, the W bosons are both much more massive than either the proton or the neutron, but they come in either positively or negatively-charged forms.

Quote from: jerrygg38 on 16/02/2020 13:18:45
Equation one for the MKS system is not valid for any other system unless we change the constants.

Which means the equation is wrong. You don't have to change the constants to get the right answer between measurement systems in truly accurate equations such as the kinetic energy equation. It is 0.5mv2. This works for any measurement system without having to change the constants. Here is an example:

For metric:

Ek = (0.5) x (1 kilogram) x (100 meters per second)2
Ek = 0.5 x 1 x 10,000
Ek = 0.5 x 10,000
Ek = 5,000 joules

For imperial:

Ek = (0.5) x (0.0685218 slugs) x (328.084 feet per second)2
Ek = 0.5 x 0.0685218 x 107,639.111
Ek = 0.0342609 x 107,639.111
Ek = 3687.81 foot-pounds

Since 1 joules equals 0.737562 foot-pounds, multiplying 5,000 joules by 0.737562 should give the same result as calculated in the Imperial equation. And, indeed, 5,000 x 0.737562 = 3,687.81 foot-pounds. So the equation gives the same result without having to change either of the constants (the 0.5 and the exponent of 2).
