Are there two different gravitational interactions? That two different-size graviton transports.

By following supermassive black holes researchers hope that they can see where gravitational waves forming. When two supermassive black holes impact each other. They form an extremely high-energy area between those black holes. There are standing waves between those black holes.

And sometimes, people think that gravitons and gravitational waves can also form between those kinds of black holes. The supermassive black holes that orbit each other also pump energy in the middle of that system. That energy reflects from deep inside the black hole. And that energy is the thing called gravitational waves.

"Following 15 years of observing pulsars, the NANOGrav collaboration has detected gravitational waves stronger than ever before, likely produced by supermassive black hole pairs. This groundbreaking discovery presents the first evidence for the gravitational wave background, which is surprisingly louder than anticipated, possibly pointing to an abundance of supermassive black holes or alternative gravitational wave sources."

Models show that strong gravitational waves impact the point between those black holes. Those impacting gravitational waves can form standing gravitational waves between black holes. And that thing could send reflection around the space.

"In this artist’s interpretation, a pair of supermassive black holes (top left) emits gravitational waves that ripple through the fabric of space-time. Those gravitational waves compress and stretch the paths of radio waves emitted by pulsars (white). By carefully measuring the radio waves, a team of scientists recently made the first detection of the universe’s gravitational wave background.

If some phenomenon has two wavelengths. That means those wavelengths must have different-size origins. In some theoretical models. The origin of high-amplitude gravitational waves origin is in the strings between quarks and gluons. That causes a question: are there two sizes of gravitons? Large gravitons transport gravitational waves with long wavelengths. And small gravitons transport the high frequency or short gravitational waves.

So are the hypothetical gravitons particles that are forming when strings between quarks and gluons oscillate. That forms a standing wave between quarks and gluons. Gluons are strong nuclear force transportation particles. So is a graviton particle that nobody has confirmed in the interaction between strings that are inside the atom's nucleus, between quarks and gluons.

There are two types of gravitational waves in space. The gravitational waves can have long and short wavelengths. That means that some people think that there are two different gravitational types. The gravitation travels in the form of long gravitational waves. And another wavelength type is short.

This means there is a possibility that the material could be at two points where gravitational waves can be left. Maybe extremely massive objects can send gravitational waves from their shell.

And the origin of short-wavelength gravitational waves may be in the atom's or subatomic particles or the connections between quarks and gluons. The gravitational waves with long wavelengths can be in the entire atoms. Or it's an oscillation that is leaving from proton's and neutron's shells.

Will humans survive the sun's red giant stage?

"As the Sun matures into a Red Giant, the oceans will boil and Earth will become uninhabitable." (The Conversation, The sun won’t die for 5 billion years, so why do humans have only 1 billion years left on Earth?) Sooner or later, all stars use their hydrogen. And then they turn into red giants. Sun is a yellow G spectral class star that turns into a white dwarf. But before that, the sun will turn larger. The sun turns red and that means. It starts to send more infrared radiation. This thing will turn Earth into a hellish temperature that vaporizes water from Earth. It's possible. That Earth will also vaporize with Venus and Mercury. Some scientists say that we have only 1 billion years to move farther in the solar system. The habitable zone will go to the distance of Jupiter and Saturn, and maybe humans find a safe place in those distant moons. It's possible that before Sun will grow too large humans make large groups of mirror satellites or large shields that sho...

Metamaterials can change their properties in an electric- or electro-optical field.

"Researchers have created a novel metamaterial that can dynamically tune its shape and properties in real-time, offering unprecedented adaptability for applications in robotics and smart materials. This development bridges the gap between current materials and the adaptability seen in nature, paving the way for the future of adaptive technologies. Credit: UNIST" (ScitechDaily, Metamaterial Magic: Scientists Develop New Material That Can Dynamically Tune Its Shape and Mechanical Properties in Real-Time) Metamaterials can change their properties in an electric- or electro-optical field. An electro-optical activator can also be an IR state, which means. The metamorphosis in the material can thermally activate. AI is the ultimate tool for metamaterial research. Metamaterials are nanotechnical- or quantum technical tools that can change their properties, like reflection or state from solid to liquid when the electric or optical effect hits that material. The metamaterial can cru...

The new observations and observation tools are revolutionizing nanotechnology and the way of thinking in physics.

ScitechDaily.com "A new study has overturned a fundamental principle of physics by demonstrating that similarly charged particles can attract each other in a solution, with the effect varying between positive and negative charges depending on the solvent. This discovery has significant implications for various scientific processes, including self-assembly and crystallization". (ScitechDaily, Opposites Attract, Likes Repel?
