Black holes do not exist

[Dennis Tate]

OK.
'Belief' holds no truck with science.
Things in nature don't have 'purpose' or 'function'.

You may well derive some comfort from your being on somewhat the same page as Mr. John Horgan when it comes to the type of theories that fascinate me.

"Now, Hawking is telling us that unconfirmable M-theory plus the anthropic tautology represents the end of that quest. If we believe him, the joke's on us." (John Horgan)

Exactly, time cannot be synchronized, it is a result of duration of physical change.

Note that metronomes have adjustable time rate slides which must match, else the metronome is unable to match the rate of duration of the other metronomes and acquire synchronicity.

p.s. river, how do you account for the synchronized flashes of the fireflies. Nothing physical between them, yet they flash in perfect synchrony .

Not time slides , how does time " slide " .

Metronomes get in synch through movements which passed to all others . Time had nothing to do with the synch .

OK, edited it to read "time rate". Move the weight up or down the slide to control the rate of time as set by the musician.

Metronome

A metronome, from ancient Greek μέτρον and νέμω, is a device that produces an audible click or other sound at a regular interval that can be set by the user, typically in beats per minute. Metronomes may include synchronized visual motion. Musicians use the device to practise playing to a regular pulse. Normal bpm: 35 to 250 BPM

Movement .

Movement creates duration (time).

And All these " time rates " are based on the Physical movements of the metronome

So what does that tell you?

What started the metronome moving ? The physical .

Right, Time is created (emerges) along with duration of movement.

By adjusting the metronome, the musician is setting the rate of time for his/her composition. Local time within Universal time.

Yes but not time . To observers there is time . To objects there is duration based on the environment and their properties .

What is duration recording?

Duration Recording is a means of collecting information on the length of a specific behavior by noting the time the behavior begins and ends.Oct 4, 2018

This form of data collection is effective when there is a clear beginning and end to the behavior, when the length of time the behavior occurs is a primary concern, and not behaviors that start and stop quickly or occur at a high frequency. Frequency counts (how often the behavior occurs) are used here.

Physicist Develops Software Solution to Measure Black Hole Stability

The existence of black holes was first predicted by Einstein’s general theory of relativity. These objects have so strong gravitational pull that nothing, not even light, can escape them. Dense and massive, black holes deform space-time (a physical construct with three spatial and one temporal dimension). Many mathematical models used to describe black holes include corrections to account for such space-time curvatures. The main condition of existence for every black hole model is its stability in cases of minor spatial or temporal changes. Mathematically unstable black holes make no physical sense, as the objects they describe cannot exist in reality. A physicist from RUDN University suggested a method to identify black hole instability parameters in 4D space-time.

“For a model to be considered feasible, a black hole described by it has to remain stable in case of minor space-time fluctuations. One of the most promising approaches to developing alternative gravity theories includes adding corrections to Einstein’s equation, including the fourth-order Gauss-Bonnet correction and the Lovelock correction that provides a higher level of generalization,” said Roman Konoplya, a researcher at the Educational and Research Institute of Gravitation and Cosmology, RUDN University.

The physicist studied stability in the Einstein-Gauss-Bonnet theory in which a black hole is described by Einstein’s equation with a fourth additional component. Previously, he had focused on a different mathematical description of a black hole, the so-called Lovelock theory, that describes a black hole as a sum of an infinite number of components. The instability region turned out to be closely associated with the values of the so-called coupling constants: numerical coefficients by which the corrections to Einstein’s equation are multiplied......more

Based on the physical . Duration is based on the physical movements of things . Do you think that the duration date matters to physical objects themselves ? Their movements . No . The beginning and end is dictated by the physical objects themselves . Dates are irrelevant .

Because they are coming to the conclusion that the mathematics doesn't match observation . Galactic Jets for example . Which eject from both poles . Not one pole as black-hole theory would suggest .

I agree. Date and Time only have meaning to humans.
All other organisms only experience duration, some of which maybe shortly remembered by living cells, some with long duration in brained animals, for purposes of migration, hibernation, mating, hunting , fruiting.

No black-holes , which are suppose to be at the center of all Galaxies .

How do you know that what you are observing is located at the center of a galaxy.
Remember, Galaxies are subject to dynamic distortion from a variety of external influences.
Remember also that the light from pulsars may have been emitted 10 billions of years ago and the pulsar has since collapsed into black hole. Not saying that's how it happens but given the age of human science, galaxies are much older objects than our solar system, so what we see is no longer there. [quote[Most galaxies are between 10 billion and 13.6 billion years old. Our universe is about 13.8 billion years old, so most galaxies formed when the universe was quite young![/quote]

Astronomers believe that our own Milky Way galaxy is approximately 13.6 billion years old. The newest galaxy we know of formed only about 500 million years ago.
