The dark matter hypothesis is not perfect, but the alternatives are worse

You may not be a fan of dark matter, the hypothetical particle that makes up the bulk of the mass in the universe. And it’s true that the dark matter hypothesis has its flaws – and of course we haven’t found any dark matter particles yet. But the truth is that the alternatives are much worse.

The universe is full of unexplained mysteries (which is what keeps astronomers and astrophysicists so happy to work), and many of these mysteries surround gravity. As we observe stars orbiting the centers of their galaxies, we find that they are moving too fast for the amount of visible matter that can hold them in these orbits by their gravity.
