What Does Dark Matter Do

Once they get a good idea of what it actually is that is what particles it s made of they ll be able to. Although both dark matter and ordinary matter are matter they do not behave in the same way. As humans we can only do so much if ordinary matter is essentially oblivious to anything but dark matter s very existence.

Although dark matter makes up most of the matter of the universe it only makes up about a quarter of the universe s total composition.

What does dark matter do. We know that dark matter exists because of the effect it has on objects that we can observe directly. Dark matter is a theorized form of matter that exists in our universe. Dark matter does not bend light itself. In particular in the early universe ordinary matter was ionized and interacted strongly.

That includes its gravitational pull. Light follows the curvature of spacetime resulting in the lensing effect. It s known as dark matter which is itself a placeholder like the x or y used in algebra class for something unknown and heretofore unseen. One day it will enjoy a new name but today we re stuck with the temporary label and its connotations of shadowy uncertainty.

Mass in this case the mass of the dark matter bends spacetime. Dark matter is composed of particles that do not absorb reflect or emit light so they cannot be detected by observing electromagnetic radiation. Dark matter could be white dwarfs the remnants of cores of dead small to medium size stars. Dark matter is material that cannot be seen directly.

Scientists study dark matter by looking at the effects it has on visible objects. It doesn t interact with baryonic matter and it s completely invisible to light and other forms of electromagnetic radiation making dark matter impossible to detect with current instruments. It can however be detected by its influence on other material in the universe. But if dark matter has some more interesting properties researchers.

But there are other aspects of dark matter than researchers are still discovering and explaining. The term theorized means that no one has been able to see dark matter but we have been able to perceive the effects of dark. Or dark matter could be neutron stars or black. Dark matter possibly could be brown dwarfs failed stars that never ignited because they lacked the mass needed to start burning.

Dark matter versus dark energy. Dark matter can t be seen felt tasted smelled or imaged. In many ways scientists know more about what dark matter is not though they do have a few ideas about what it could be.
