What dark matter is not?

Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter.

What dark matter Cannot be?

Dark matter is material that cannot be seen directly. We know that dark matter exists because of the effect it has on objects that we can observe directly. Scientists study dark matter by looking at the effects it has on visible objects.

What does dark matter not give off?

Dark matter is called "dark" because it does not appear to interact with the electromagnetic field, which means it does not absorb, reflect, or emit electromagnetic radiation (like light) and is, therefore, difficult to detect.

Is dark matter Non matter?

Most scientists think that dark matter is composed of non-baryonic matter. The lead candidate, WIMPS (weakly interacting massive particles), are believed to have ten to a hundred times the mass of a proton, but their weak interactions with "normal" matter make them difficult to detect.

What could dark matter be?

It could be made of weakly interacting massive particles; hypothetical particles like axions; or even dark atoms that do not interact with ordinary matter or light.

This Will Change Physics! Dark Matter May Not Exist!

Is dark matter the 4th dimension?

Dark Matter is the matter that exists in the fourth spatial dimension as 4-D matter spewed there through the Black Hole singularities of our third dimension.

Are black holes dark matter?

Summary: Astrophysicists suggest that primordial black holes account for all dark matter in the universe.

Are neutrinos dark matter?

Neutrinos are one candidate for dark matter but only if they have a nonzero rest mass. Neutrinos interact only via the weak force and gravity which would explain we don't see dark matter can't be detected through interactions with light like baryonic (normal) matter.

What is an axion particle?

An axion (/ˈæksiɒn/) is a hypothetical elementary particle postulated by the Peccei–Quinn theory in 1977 to resolve the strong CP problem in quantum chromodynamics (QCD). If axions exist and have low mass within a specific range, they are of interest as a possible component of cold dark matter.

Is dark matter solid?

However, if instead the dark matter is a solid, with an elastic resistance to pure shear deformations, an equation of state with negative presure can avoid these short wavelength instabilities. Such a solid may arise as the result of different kinds of microphysics.

Does anti matter exist?

For the past 50 years and more, laboratories like CERN have routinely produced antiparticles, and in 1995 CERN became the first laboratory to create anti-atoms artificially. But no one has ever produced antimatter without obtaining the corresponding matter particles also.

Is electromagnetic radiation dark matter?

Dark matter does not reveal its presence by emitting any type of electromagnetic radiation. It emits no infrared radiation, nor does it give off radio waves, ultraviolet radiation, X-rays or gamma rays.

Can you touch dark matter?

When we look out into the universe, we don't know what we're looking at for the most part. In fact, we can't even see most of what we're looking at – that's because the majority of the universe is made up of mysterious, practically invisible dark matter.

Can a wormhole exist?

In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world.

Is dark matter just space dust?

So no, dark matter can't just be normal matter in some combination of forms that don't emit light; there really needs to be something else out there that isn't made of any of the particles in the Standard Model! Not only does dark matter exist, but it's an entirely new type of matter, something we have yet to discover.

How many antimatter do we have?

Humans have created only a tiny amount of antimatter.

All of the antiprotons created at Fermilab's Tevatron particle accelerator add up to only 15 nanograms. Those made at CERN amount to about 1 nanogram. At DESY in Germany, approximately 2 nanograms of positrons have been produced to date.

How fast is a tachyon?

Tachyons are one of the most interesting elements arising from Einstein's theory of special relativity. The 1905 theory is based on two postulates, nothing with mass moves faster than the speed of light (c), and physical laws remain the same in all non-inertial reference frames.

What is a pseudoscalar particle?

Pseudoscalar particles, i.e. particles with spin 0 and odd parity, that is, a particle with no intrinsic spin with wave function that changes sign under parity inversion. Examples are pseudoscalar mesons.

What is graviton particle?

graviton, postulated quantum that is thought to be the carrier of the gravitational field. It is analogous to the well-established photon of the electromagnetic field. Gravitons, like photons, would be massless, electrically uncharged particles traveling at the speed of light.

Is Higgs boson a neutrino?

We present a realization of the idea that the Higgs boson is mainly a bound state of neutrinos induced by strong four-fermion interactions.

Are neutrinos Tachyons?

Neutrinos. In 1985, Chodos proposed that neutrinos can have a tachyonic nature. The possibility of standard model particles moving at faster-than-light speeds can be modeled using Lorentz invariance violating terms, for example in the Standard-Model Extension.

Is dark matter made of quarks?

The particle is composed of six quarks -- the fundamental particles that usually combine in trios to make up protons and neutrons.

What is the opposite of a black hole?

White holes, which are theoretically the exact opposites of black holes, could constitute a major portion of the mysterious dark matter that's thought to make up most of the matter in the universe, a new study finds. And some of these bizarre white holes may even predate the Big Bang, the researchers said.

What are the 4 types of black holes?

There are four types of black holes: stellar, intermediate, supermassive, and miniature. The most commonly known way a black hole forms is by stellar death. As stars reach the ends of their lives, most will inflate, lose mass, and then cool to form white dwarfs.

What is a white black hole?

White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
