Two of the biggest mysteries in physics are: where is all the dark matter that scientists know is in the universe but can't see?—and are there extra
dimensions beyond the 3 we can see? A team of scientists now think these mysteries may be connected. "For the most part, these two questions have
been treated separately in the past, and for the first time we're making a direct link," says Konstantin Matchev. "We're suggesting that the dark
matter may be due to extra dimensions."
This could lead to the first concrete evidence of dark matter, which may make up 30% of the universe. Evidence of its existence comes from the
difference between the rate galaxies rotate and the number of stars within them. There aren't enough stars or planets to account for the speed,
meaning dark matter must also be present, but no one knows what it's made of or where it is.
