Who discovered dark matter?

Answer 1

Dark matter wasn't "discovered" by any one person or group. In fact it is still hypothetical and there is no solid proof for its existence. Various astronomers inferred the existence of dark matter from what they observed about galaxies and galaxy clusters. It is still very much a mystery and the subject of some serious research.

Answer 2

You will find it interesting that in fact dark matter has not yet been discovered. We are trying hard to observe evidence of dark matter, but it is not revealing itself at this time. It is theorized to be there, based on what we know about how the galaxies are moving and how they are interacting with one another. Dark matter is a theory waiting for verification.

Answer 3

Caltech astrophysicist Fritz Zwicky (Swiss) first offered the idea of something that later evolved into dark matter back in 1933. The puzzle hung around for a long time with no action. Then in 1975, Vera Rubin and her fellow staffer Kent Ward stunned the astronomical world. The two were at the Carnegie Institution of Washington's Department of Terrestrial Magnetism. They made the announcement that most stars in a spiral galaxy orbited the galactic center at about the same speed. What's up with that? Let's look. Consider that Mercury orbits the sun in about 88 days. It's close, and it's gotta move fast. Earth makes a trip around the sun in 365 days (plus or minus) 'cause it's farther away. Imagine all planets orbiting the sun at the same speed. Crazy! How is this possible? There'd have to be some kind of "distributed mass - and a lot of it! - to make things "flow" at pretty much the same velocity like they do in a spiral galaxy (or any galaxy). What could this stuff be? Dark matter. And something like three quarters of the universe is composed of it. Amazing! Totally! [The truth is, we don't know what's up with dark matter. We're almost clueless. But the fact is that most of the stars do orbit a spiral galaxy at about the same speed. That is a bulletproof bite of data. No gettin' around it. As gravity is the force responsible for what we see (coupled with the inertia of the stars) what's going on? We're stumped. Want a Nobel Prize? Solve this one. You'll be a lead pipe cinch for one.] A link is provided to our friends at Wikipedia.

Answer 4

We do not actually know that dark matter exists and have no idea what it is if it does exist.

What we see that leads us to think that there is something that we call dark matter is that there is not enough visible matter in galaxies and galactic clusters to account for their observed gravitational coherence. We must therefore postualte that either our understanding of the laws of gravity are deficient or that 75% of the matter in the universe is undetectable/unobservable to us. We call this unobservable matter "dark matter".

If it exists it will occur round galaxies and in the intergalactic web structure.

Answer 5

Upon observing the rotational velocities of galaxies within a cluster, Fritz Zwicky, in 1933, stated that there was a "missing mass" or "dark matter" problem. For some reason, astronomers simply ignored his work for over four decades.

Answer 6

We do not know what dark matter is or even if it actually exists, ITs presence is inferred from the fact that galaxies rotate so fast that they would fly apart if there was not more mass present in them than we can see (hence dark matter). It is thought that if it exists, dark matter will surround galaxies as a sort of halo.

Answer 7

Dark matter makes up a majority of the mass in the universe and can be found orbiting stars, on the edges of galaxies, or traveling freely through space.

Answer 8

it takes up 2 24 hrs i honestly think but if it did then we wouldn't be here

Answer 9

No one invented dark energy. It is a possible property of the universe like gravity. The first person to conceive of an idea somewhat like the current idea of dark energy was Alan Guth.
