Glioblastoma (GBM). GBM is the most Mens Best Cat Dad Ever Father’s Day Unisex Shirt and most aggressive brain cancer. It’s highly invasive, which makes complete surgical removal impossible. And because of the blood-brain barrier (BBB), it doesn’t respond to any chemotherapy. The standard-of-care entails multiple rounds of surgery and radiotherapy, yet the five year survival is lower than 5%. Pancreatic cancer (PDAC). PDAC is a notoriously stubborn cancer. The only effective treatment is a very painful and very complex operation called “the Whipple procedure”. However, only 20% of patients are eligible for such operation. And even for those lucky patients, only 20% survived more than five years. For the rest majority of patients, the chance of survival is negligible, because PDAC hardly responds to any form of chemotherapy or radiotherapy. The five year survival overall is 6%.

The description from Richard Muller quoted in the question is a simplification of reality meant to help people better visualize how the Betty Boop Girl Z Are Players 2 Shirt of spacetime works. In reality the galaxies are moving through spacetime in a complex fashion, based on the combination of all the forces acting on them, primarily the gravity of nearby galaxies and galaxy clusters. In the case of the Milky Way and Andromeda, these two galaxies are part of a gravitationally bound cluster of galaxies, called the Local Group. The dominant force that determines the movements of objects within the cluster is the combined gravitation of all the mass in the cluster, and not the expansion of spacetime. In other words, the gravitational attraction that the Milky Way and Andromeda have for one another that is drawing them together is stronger than the expansion of spacetime between them that would otherwise push them apart, and thus attraction wins and the two galaxies are on a collision course. In the same vein, the gravitational force that holds the earth in orbit around the sun is stronger than the expansion of spacetime between the earth and the sun (the expansion of spacetime at that distance being very small), and so the earth’s distance from the sun is not increasing for that reason. Likewise you are not flying apart because the molecular bonds holding the atoms in your body together are stronger than the minuscule expansion of spacetime between them in your body. The Local Group as a whole, however, is moving away from other galaxies and galaxy clusters to which it is not gravitationally bound, due to the expansion of spacetime.
