WebOur galaxy, the Milky Way, is typical: it has hundreds of billions of stars, enough gas and dust to make billions more stars, and about six times as much dark matter as all the stars and gas put together. And it’s all held together by gravity. Like more than two-thirds of the known galaxies, the Milky Way has a spiral shape. At the center of the spiral, a lot of … WebAbell 1689 is one of the biggest and most massive galaxy clusters known and acts as a gravitational lens, distorting the images of galaxies that lie behind it.

WebSep 3, 2024 · Because these gravitons leave the galaxy at a rate lower than they would in the absence of self-interactions, the gravitational pull between galaxies is weaker than it would be in the absence of gravitational self-interaction. Thus, dark energy is due to a weaker pull between galaxies than in the Newtonian or cosmological constant free …
