Today I was having a walk while smoking a joint when the idea occured to me: Dark matter is light. As simply as that. Radiated by the galaxy, its contribution to bend the gravitational field is huge because of the immense volume. I was happy to realise this, and I wondered if someone had thought it first. Making a google search I found:

Some dude had the idea first 7 years ago, and he was mocked. But I know he's right!

There is this crazy physicist, Miles Mathis, who said the same in 2019, nobody took him seriously just because of his funny prose

The academia first started to study this less than a year ago.

I just can't help smiling thinking of all the media telling soon: Guess what? Dark matter is light! Amazing!

That's it, folks, thanks for reading. Have a nice day
