This could proceed ad infinitum without a hint of progress.
I've measured voltages higher than the national standard, whilst working at a national standards lab!The trick is to make a device that is modular and inherently linear and extendable, then calibrate the modules and add them together. It is left as an exercise to the reader to work out how to do this with temperature. Hint: Johnson noise is good to the boiling point of carbon, and a buddy of mine uses spectroscopy to measure the temperature of plasmas with a diffraction grating traceable to common mechanical standards.
Something mysterious is going on at the Sun. In defiance of all logic, its atmosphere gets much, much hotter the farther it stretches from the Sun’s blazing surface.Temperatures in the corona — the tenuous, outermost layer of the solar atmosphere — spike upwards of 2 million degrees Fahrenheit, while just 1,000 miles below, the underlying surface simmers at a balmy 10,000 F. How the Sun manages this feat remains one of the greatest unanswered questions in astrophysics; scientists call it the coronal heating problem. A new, landmark mission, NASA’s Parker Solar Probe — scheduled to launch no earlier than Aug. 11, 2018 — will fly through the corona itself, seeking clues to its behavior and offering the chance for scientists to solve this mystery.
Not until 70 years later did a Swedish physicist discover the element responsible for the emission is iron, superheated to the point that it’s ionized 13 times, leaving it with just half the electrons of a normal atom of iron. And therein lies the problem: Scientists calculated that such high levels of ionization would require coronal temperatures around 2 million degrees Fahrenheit — nearly 200 times hotter than the surface.

If Earth was at one end of a yard-stick and the Sun on the other, Parker Solar Probe will make it to within four inches of the solar surface.Inside that part of the solar atmosphere, a region known as the corona, Parker Solar Probe will provide unprecedented observations of what drives the wide range of particles, energy and heat that course through the region — flinging particles outward into the solar system and far past Neptune.Inside the corona, it’s also, of course, unimaginably hot. The spacecraft will travel through material with temperatures greater than a million degrees Fahrenheit while being bombarded with intense sun light.So, why won’t it melt?Parker Solar Probe has been designed to withstand the extreme conditions and temperature fluctuations for the mission. The key lies in its custom heat shield and an autonomous system that helps protect the mission from the Sun’s intense light emission, but does allow the coronal material to “touch” the spacecraft.NASA's Parker Solar Probe is heading to the Sun. Why won't the spacecraft melt? Thermal Protection System Engineer Betsy Congdon (Johns Hopkins APL) outlines why Parker can take the heat.Credits: NASA's Goddard Space Flight CenterDownload this video in HD formats from NASA Goddard's Scientific Visualization StudioThe Science Behind Why It Won’t MeltOne key to understanding what keeps the spacecraft and its instruments safe, is understanding the concept of heat versus temperature. Counterintuitively, high temperatures do not always translate to actually heating another object.In space, the temperature can be thousands of degrees without providing significant heat to a given object or feeling hot. Why? Temperature measures how fast particles are moving, whereas heat measures the total amount of energy that they transfer. Particles may be moving fast (high temperature), but if there are very few of them, they won’t transfer much energy (low heat). Since space is mostly empty, there are very few particles that can transfer energy to the spacecraft.

Quote from: Deecart on 18/09/2022 19:13:19Now, yes the heat is also a mechanical energy, but he say it himself... it is a statistical mechanical energy.What's the difference between statistical mechanical energy and non-statistical mechanical energy?How would it compare to temperature? Is there a statistical mechanical energy which is not kinetic? What would it be called?

Entropy is a fundamental concept in Data Science because it shows up all over the place - from Decision Trees, to similarity metrics, to state of the art dimension reduction algorithms. It's also surprisingly simple, but often poorly explained. Traditionally the equation is presented with the expectation that you memorize it without thoroughly understanding what it means and where it came from. This video takes a very different approach by showing you, step-by-step, where this simple equation comes from, making it easy to remember (and derive), understand and explain to your friends at parties.

There's a point where you have to let the experts be experts.This is true even (some might say "especially") when you don't understand the question.

hamdani, gravity is the opposite of entropy. While stars grow to great size, they will not increase in mass. Yet one day the universe will be 1 star that will collapse into itself causing another big bang. The big bang theory says the universe will become 1 small piece of matter that is extremely dense. Maybe you could consider an event horizon? Matter is created while some matter is absorbed. And that increases what created the event horizon. That has nothing to do with heat. Heat is nothing more than conserved electromagnetic radiation being released as e = hv. And it's collisions between molecules that release heat/electromagnetic radiation.
so it will surely
I don't think that your prediction above is in the mainstream view of astrophysics community.
