THE TRUE REASON WHY GALAXIES WITH LESS DARK MATTER THAN EXPECTED EXIST!

Ooooh hello dear reader! A bunch of Chinese astronomers discovered (P) 19 dwarf galaxies that have way less dark matter than expected, and they don't know how this be possible, considering that in "the standard cosmological model, dark matter drives the structure formation of galaxies and constructs potential wells within which galaxies may form" (P).

This dumb blog, though, has a theory...

NOTE
Universe composition: 
- 5%, matter [you, Bernard* (the weird little guy depicted on top of the vending machine, with a "B" all over its/his/her... Well, the part between the head and the legs), vending machines, hippos, the annoying neighbor, the annoying neighbor's annoying pet(s), Monica Bellucci, the piece of lettuce stuck between your front teeth during your dream job interview/first date with your huge crush of ten years, Tom Selleck's mustache, all the things inside a woman purse, all the things disappeared inside a woman purse, broccoli, the stars, the stars which don't go to the talk shows 'cause they're too busy doing nuclear fusion, aaaand so on)
- 27% dark matter (who knows, I just draw my two cents 'bout it)
- 68% dark energy (see above)

* Ok, ok, technically Berny's not matter, is an idea (and not even a slightly brilliant one), but with billions of worlds out there, well, who knows...

THE TRUE REASON WHY THE UNIVERSE IS GETTING BIGGER WAY FASTER THAN PREDICTED

Sooo dear reader, scientists have found out that, at the moment, the universe is getting bigger and bigger waaay faster than predicted.

It may depend on some new kind of dark energy, or on some new unknown particle, ooor on some new physics in need to be discovered altogether.

Those are all good hypothesis, indeed.

But this dumb blog has a different one...

HAPPY B-DAY LEMAITRE!

Happy birthday to Georges Henri-Joseph-Edouard Lemaître (aka Abbé Lemaître, since, after serving, as a volunteer, in the belgian artillery during the 1st World War and gaining a Military Cross, the man enters the seminary and becomes a priest), dad of the Big-Bang Theory (the 1927 science stuff*, not the 2007-still-on-air tv-show stuff... C'mon dude!)

By the way, do you know that the term "Big-Bang" comes up as a mockery of Lemaitre's theory in a 1950 radio broadcast? Yup, English astronomy dude Sir. Fred Hoyle (who is all into the concept of a static homogeneous universe that never started and will never end) that year does a thing where he explains science to common people. The thing is a series of five lectures, by Hoyle himself, about stars and the universe. The lectures air on the Third Programme (the present Radio 3) of the English BBC network, aaaand during the last of these radio lessons, well, our guy Hoyle spits his "Big-Bang"ing disdain on his colleague's cosmological idea... Sic!
