In reference to Dark Matter?

Question

This experiment they are doing off the coast of hawaii is an attempt to identify dark matter? If I am understanding this correctly if I am not just disreguard. If you can give me a quick run down on that I would appreciate it. I am just trying to understand this more, if they do identify dark matter how does this effect Neuton and Einsteins theories?

Answer 1

The fate of the Universe is basically a battle fought between the inward pull of gravity and the outward push of expansion. So astronomers are trying to calculate the strength of these forces. The amount of gravity the Universe has to wield against this expansive onslaught depends on how much stuff there is out there in space. Anything with a mass has its own gravity. Even you yourself have a gravitational force that attracts everything else around you, including other people. The bigger you are, the stronger this force is, and so, the Earth, being the most massive thing around, completely overwhelms the tiny forces that we personally possess. So to calculate the fate of the Universe, we must weigh it to find its density.

Answer 2

I saw a brief news article quite recently, where scientists claim that the existence of dark matter has been confirmed by observational, not experimental, evidence.

Somewhere they found two galaxies that are in the process of colliding. Analyzing velocities -- whether angular or rectilinear, I don't recall -- they confirm the existence of dark matter.

Some reputable scientists not involved in the project say that these results constitute convincing proof.

Newton's and Einstein's theories are unaffected. The problem had been that if matter is confined to matter, the amount of mass contained in galaxies is insufficient to prevent the galaxies from flying apart. So they hypothesized that dark matter subject to gravitational attraction must exist.

This latest seems to confirm that hypothesis.

But that doesn't end the story. Although I've forgotten the details, they say visible matter may only comprise a small percentage (maybe 5%) of everything in the universe; dark matter, maybe another 25%; and something else (energy??) the remaining 70%.

Further complicating things is the possibility that there may be "antimatter" that accelerates expansion via "antigravity". So ...

Answer 3

Do you know the name of this experiment? I haven't heard about it so I can't tell you anything about it, and since I don't know what it's called I can't even google it.

Answer 4

Evil energy.

sorry i don't know
