Repulsive Gravity as an Alternative to Dark Energy (Part 1)

The Local Sheet, which includes the Local Galactic Group and other nearby galaxies, has a peculiar velocity that can theoretically be explained by the repulsive gravity of antimatter in a large void, among other components. Image credit: Wikimedia Commons (CC BY-SA 3.0)

(PhysOrg.com) — When scientists discovered in 1998 that the Universe is expanding at an accelerating rate, the possibility that dark energy could explain the observation was intriguing. But because there has been little progress in figuring out exactly what dark energy is, the idea has since become more of a problem than a solution for some scientists. One physicist, Massimo Villata of the National Institute for Astrophysics (INAF) in Pino Torinese, Italy, describes dark energy as “embarrassing,” saying that the concept is an ad hoc element to standard cosmology and is devoid of any physical meaning. Villata is one of many scientists who are looking for new explanations of the Universe’s accelerating expansion that involve some form of repulsive gravity. In this case, the repulsive gravity could stem from antimatter hiding in voids.

1998 Leonid Fireball

This is how you ruin one.

So I understand that branding is the name of the game. I get it. Hey, in some ways, I’m a part of the “problem”. My problem isn’t the logo madness all over the bike… it’s the LV logos on the seat. I’m gonna go here, though it’s an unpopular opinion. The LV logo pattern is tired. Why we insist on draping it on everything is beyond me. Unless you have a big old trunk that’s been in your family for years, it’s time to let this thing go.
