How does dark matter affect us?

Answer 1

"Dark Matter" is currently only a mathematical concept, a "fudge factor" thrown into some calculations to make the numbers work out. We have no idea if "dark matter" really exists, how it would affect the universe, or how it might be detected or manipulated. It's all guesswork, and all the scientists have conflicting guesses.

For myself, I suspect that there are some fundamental things that our theories do not yet understand, and that in the future, we'll discover that "dark matter" will prove to be nothing at all.

Answer 2

The fate of the universe is dependent of the density of mass in it. If the mass is too small, then the universe will keep growing forever, becoming a cold and relatively empty place. If there is too much mass, the universe will collapse in on itself, bringing everything together in a white hot crunch. If there is just the right amount of mass, the universe will stop expanding, but neither will it contract. It will stay static. Determining how much dark matter there is would help determine which fate we are headed for. Research has found that the rate at which the universe is increasing is speeding up however, providing strong evidence that the universe will never stop expanding.

Answer 3

Dark matter makes galaxies and galaxy groups stay together.

It was once believed that the expansion of the Universe would slow down with time, due to the effect of gravity. Now it is known that in fact, the expansion of the Universe gets faster with time. This is attributed to a mysterious substance called "dark energy".

Answer 4

According to our computer simulations, galaxies appear to only have 20% of the mass needed to hold the number of stars in orbit that they hold. Therefore a hypothesis was created that there is a new and unknown type of matter within the galaxies to make up the difference. There could still turn out to be some other explanation.

Answer 5

Dark matter affects human only in a way if the force that is keeping galaxies in their place due to dark matter if it doesn't exist then all galaxies collide together and it will fall on earth they will destroy the existence of the humans on this earth.

Answer 6

Yes, dark matter can and does slow down the expansion of our universe. The presence of dark matter in the universe is a matter of great controversy but several theories of gravitation and formation of universe such as General Relativity predicts the existence of dark matter. This dark matter could not be observed directly but it's existence could be felt due to it's effects on the expanding universe. Dark matter possesses gravitational force as well as mass and exerts that force on bodies passing nearby. It has the capacity to slow down the expansion of universe but not that much that is completely halt it's expansion.

Answer 7

As its name suggests, dark matter is matter, and so would need to be included in a calculation for the density of matter in an area. Because we cannot see dark matter and know very little about it, however, it is difficult to accurately determine how much matter is in an area. Imagine you had a container partially filled with water, and you were asked to determine how much of the container had water in it. If you knew that some, but not all, of the water was invisible, it would be hard to answer this. Scientists need to find an accurate way of measuring dark matter before true measures of the density of matter can be carried out.

Answer 8

Dark matter is a favored explanation for anomalous behaviors seen in the rotation rate of galaxies, and other gravitational anomalies not otherwise explained through visible matter. Dark energy is an explanation for an observed acceleration rate in the expansion of the universe, which is anticipated to eventually dominate structures on cosmological scales. Both dark matter and dark energy are thought to contribute to the overall mass and eventual fate of the universe.

Answer 9

We can't say. "Dark energy" and "dark matter" are currently just mathematical abstractions; we don't know if they exist, or what properties they might have if they do. At this point, anything you read or see about dark matter and dark energy are guesses and wishful thinking.
