Has anyone seen dark matter?

Despite recent advances in astrophysics and astronomy, scientists still don't understand exactly how galaxies can exist. The most common explanation for this observational conundrum is a so-far undiscovered form of matter: dark matter. Still, dark matter has yet to be directly observed by scientists.

Has dark matter ever been seen?

Because no one has directly observed dark matter yet – assuming it exists – it must barely interact with ordinary baryonic matter and radiation except through gravity. Dark matter is thought to be non-baryonic; it may be composed of some as-yet-undiscovered subatomic particles.

Has anyone ever touched dark matter?

No. Generally, the phrase “touch” implies some surface contact between your skin and a substance. This contact fundamentally relies on electromagnetic interactions in the atoms and molecules in your skin. Since dark matter does not interact electromagnetically, you cannot touch it in the conventional sense.

Can dark matter give you superpowers?

Dark matter is the collective term given to subatomic particles which are capable of altering a human's biological structure to turn them into meta-humans and allow them to develop superpowers.

Can dark matter hurt us?

In fact, the dark matter impact would generate so much heat that it would tunnel through body tissue as a flesh-melting plasma plume, the study authors reported. Most physicists hunting for dark matter are searching for particles smaller than atoms.

The Absurd Search For Dark Matter

Has dark matter been photographed?

Using a technique known as weak gravitational lensing, the researchers combined images taken over the course of years to show the presence of dark matter. The composite was created using images from more than 23,000 galaxy pairs situated 4.5 billion light-years away.

What would dark matter do to a human?

The nuclear forces that hold your nuclei and protons together would vanish; the electromagnetic forces that caused atoms and molecules to stay together (and light to interact with you) would disappear; your cells and organs and entire body would cease to hold together.

Is space infinite?

We could think of the universe as a sphere expanding indefinitely and infinitely. Or it might curve and bend in ways that could make it a closed system (like a donut), where if you were to travel in a straight line for long enough, eventually you'd end up back where you started: space would be finite.

How many years will space end?

22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5.

Is there an unobservable universe?

It will reveal slightly more than twice the volume of the Universe we can observe today. The unobservable Universe, on the other hand, must be at least 23 trillion light years in diameter, and contain a volume of space that's over 15 million times as large as the volume we can observe.

What is beyond the end of space?

The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.

Can dark matter be weaponized?

Weaponized dark matter was dark matter that had been made into a weapon by converting it into a small sphere that could rip molecules at a subatomic level, thus killing an individual.

Can you physically touch dark matter?

In fact, recent estimates put dark matter as five times more common than regular matter in our universe. But because dark matter does not interact electromagnetically, we can't touch it, see it, or manipulate it using conventional means.

How hot is dark matter?

According to their calculations, dark matter is “tepid” – about 10,000°C. By comparison, the surface of the Sun is about 6000°C, while its core is about 15.5 million °C. “This temperature tells us something very fundamental about the properties of dark matter,” says Gilmore.

Is dark matter just black holes?

Also popular is a theory that dark matter is made of lighter but equally hypothetical particles called axions. But over the past half-decade or so, some researchers have become more open to an older idea: Dark matter consists of primordial black holes (PBHs) that emerged from the Big Bang.

What does dark matter look like in real life?

Dark matter is completely invisible. It emits no light or energy and thus cannot be detected by conventional sensors and detectors. The key to its elusive nature must lie in its composition, scientists think.

Who created dark matter?

The term dark matter was coined in 1933 by Fritz Zwicky of the California Institute of Technology to describe the unseen matter that must dominate one feature of the universe—the Coma Galaxy Cluster.

What happens if you collide dark matter?

Dark matter particles can penetrate all other forms of matter, which means that they may even be able to traverse right through our planet without losing any energy whatsoever. On the other hand, their impact with ordinary matter that Earth is comprised of may hamper them slightly, resulting in a loss of energy.

What happens if strange matter touches you?

As physicist Edward Farhi described it, “A lump of strange matter has an insatiable appetite for neutrons and grows fat by eating them.” Anything coming into contact with the border of strange matter would be consumed by it, altered at a subatomic level until the normal matter itself became strange.

Has anyone isolated dark matter?

So far, not a single experiment has yielded a definitive trace of dark matter. But these experiments haven't failed – in fact, many have been quite successful.

What is more powerful than dark matter?

Dark energy is the far more dominant force of the two, accounting for roughly 68 percent of the universe's total mass and energy. Dark matter makes up 27 percent. And the rest — a measly 5 percent — is all the regular matter we see and interact with every day.

Is dark matter the god particle?

The Higgs boson is the God particle. It is an elementary particle in the Higgs field. It is found in the Higgs field. Dark matter is not the same as the Higgs boson.

Is dark matter just antimatter?

Third, dark matter is not antimatter, because we do not see the unique gamma rays that are produced when antimatter annihilates with matter. Finally, we can rule out large galaxy-sized black holes on the basis of how many gravitational lenses we see.

How many dimensions exist?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there's the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.

Is time Finite or infinite?

According to the conventional historical explanation, time is a neutral and infinite medium. The foundational challenge claims that time is finite: not only in the sense that we all die, but also in the more technical sense in which physicists treat time as a dimension of events, not an envelope for them.
