How was dark matter created?

Scientists believe that dark matter in the cluster accounts for the unexplained mass. Other scientists believe that dark matter may be composed of strange particles which were created in the very early universe. Such particles may include axions, weakly interacting massive particles (called WIMPs), or neutrinos.

What evidence is there for 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.

Can dark matter be created?

Several scientific groups, including one at CERN’s Large Hadron Collider, are currently working to generate dark matter particles for study in the lab. Other scientists think the effects of dark matter could be explained by fundamentally modifying our theories of gravity.

When was dark matter created?

Although the first evidence for dark matter was discovered in the 1930s, it was in the early 1980s that astronomers became convinced that most of the mass holding galaxies and clusters of galaxies together is invisible.

Is it possible dark matter doesn’t exist?

Cosmologists, physicists, and astronomers theorized that dark matter could explain the strange gravitational behavior of galaxy clusters for decades. But new research suggests that it might not exist. Dark matter has never been seen or observed.

What caused the early Sun to form?

The spin caused the cloud to flatten into a disk like a pancake. In the center, the material clumped together to form a protostar that would eventually become the sun. “There is a rotationally supported disk around this protostar,” astronomer John Tobin told Space.com about a similar early sun, adding it’s a “key element” in building planets.

How was the Solar System formed?

Credit: Space.com. In a wide expanse of space, gravity drew dust and gas together to create the young solar system. The sun formed first from the vast material, with the planets close behind.

Can scientists solve the enigmas of neutrinos from the Sun?

Now a giant scientific experiment housed deep beneath mountains in Italy is analyzing neutrinos from the sun with unprecedented detail, which might one day help solve the enigmas neutrinos pose, as well as shed light on the inner workings of stars. Neutrinos are generated by nuclear reactions and certain types of radioactive decay.

What happened to the nebula that formed the Sun?

As the nebula collapsed because of its overwhelming gravity, it spun faster and flattened into a disk. Most of the material was pulled toward the center to form our Sun, which accounts for 99.8\% of the mass of the entire solar system. Like all stars, the Sun will someday run out of energy.
