Around five billion years ago, the universe’s expansion started to speed up. We don’t know what’s causing this accelerated expansion, but we named it dark energy. From what scientists can tell, visible matter makes up only 5% of the universe. Dark matter and dark energy are believed to make up the other 27% and 68%, respectively. What dark matter is, however, is much less clear. One theory is that it is a new kind of particle, a weakly interacting massive particle (or WIMP). If that theory is correct, said Fisher, dark matter is likely all around — but “here on Earth, it’s hard to find dark matter because there’s so much normal matter around.So what exactly is dark matter? How do we know it’s there? And how are scientists looking for it? Everything we see around us – from plants to planets, stones to stars, people to …

In astronomy, dark matter is a hypothetical form of matter that appears not to interact with light or the electromagnetic field. Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be seen.

What is Dark Matter? Our galaxy is known to be surrounded by a halo of dark matter whose composition remains a mystery.
