What kind of cluster is the bullet cluster?
The massive galaxy cluster, 1E 0657-56, discovered by Tucker et al. (1998) consists of two colliding galaxy clusters at z = 0.296. In this distinct merging system, a sub-cluster, the “bullet” has collided with the main cluster, approximately in the plane of the sky (Barrena et al. 2002).
How do we think the hot gas came to be in a different place from the galaxies and most of the matter?
How do we think the hot gas came to be in a different place from the galaxies and most of the matter? The Bullet cluster is actually two separate galaxy clusters that have collided, stripping out hot gas in the process.
What is the temperature of the gas between galaxies in a galaxy cluster?
ten million kelvin
How do we know that galaxy clusters contain a lot of mass in the form of hot gas that fills spaces between individual galaxies?
How do we know that galaxy clusters contain a lot of mass in the form of hot gas that fills spaces between individual galaxies? We detect this gas with X-ray telescopes. We have detected gravitational lensing of distant objects that appears to be caused by compact but unseen objects in the halo of our galaxy.
What is the evidence of dark matter?
Primary evidence for dark matter comes from calculations showing that many galaxies would fly apart, or that they would not have formed or would not move as they do, if they did not contain a large amount of unseen matter.
Is dark matter a WIMPs?
For decades, physicists have hypothesized that weakly interacting massive particles (WIMPs) are the strongest candidate for dark matter — the mysterious substance that makes up 85% of the Universe’s mass. WIMPs became a favourite candidate for the dark matter in the 1980s.
Why is dark matter so expensive?
Due to its explosive nature (it annihilates when in contact with normal matter) and energy-intensive production, the cost of making antimatter is astronomical. CERN produces about 1×10^15 antiprotons every year, but that only amounts to 1.67 nanograms.
What is the purpose of dark matter?
Scientists believe that dark matter may account for the unexplained motions of stars within galaxies. Computers play an important role in the search for dark matter data. They allow scientists to create models which predict galaxy behavior. Satellites are also being used to gather dark matter data.
What would happen if we didn’t have dark matter?
If all the dark matter disappeared, gravity would cease to exist. Although something with a crust might come apart if enough heat is left, all objects in the plasma state definitely would be destroyed. This is because dark matter is “pressurized” in space.
Can dark matter be manipulated?
It is common throughout the universe and helps shape galaxies. 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.
Are there super humans?
The term superhuman refers to humans or human-like lifeforms with enhanced qualities and abilities that exceed those naturally found in humans. These qualities may be acquired through natural ability, self-actualization or technological aids.
Can radiation give you superpowers?
To acquire superpowers, you would need a place steeped in high-energy radiation. A radioactive particle is an unstable atom that spews energy in an attempt to restore balance. If the energy level is strong enough, then it can pass through solid barriers, like our skin, and cause changes in our DNA.
Is Mutant really exist?
“Mutants are actually extremely common,” says OMRF scientist Dr. Chris Sansam. “Someone without any mutations would be the real anomaly.” Mutations are changes to a person’s genetic code, and they can come about from exposure to an external environmental factor, such as cigarette smoke or radiation.
Can humans be mutated?
Scientists believe that every time the human genome duplicates itself there are around 100 new mutations. They’re pretty common, and usually negligible. However, it would stand to reason that within the pantheon of human mutations, some would express themselves in the form of extraordinary superhuman abilities.
Who has super power?

What are mutant people?
In American comic books published by Marvel Comics, a mutant is a human being that possesses a genetic trait called the X-gene. It causes the mutant to develop superhuman powers that manifest at puberty. Human mutants are sometimes referred to as a human subspecies Homo sapiens superior, or simply Homo superior.
