DownloadAstronomers are on a scavenger hunt that started almost 100 years ago,
searching for something right in front of their eyes.
They know something’s out there,
holding galaxies together and sculpting the
observable universe into this awesome shape.
And they’ve given it a name: dark matter.
The only problem is…no one has any idea what dark matter is.
It barely interacts with anything except through gravity.
It’s invisible, and all attempts to detect it directly have failed.
But maybe… just maybe, a giant moon orbiting Jupiter
has been collecting evidence of dark matter all along.
[♪ INTRO]
The problem with looking for dark matter is that
we don’t even really know what we’re looking for.
It’s like trying to go on an Easter egg hunt if you’ve never seen an egg before.
Also, the eggs are invisible.
