What are the uncertainties in its value?arrow_forwardDoes Hubble's Law work well for galaxies in the Local Group (such as Andromeda)? No, because dark energy is accelerating the universe's expansion over those distances. No, because we do not know the precise value of Ho. No, because Hubble did not know the Local Group existed when he discovered his law. Yes, it works well for all galaxies. No, because galaxies in the Local Group are bound gravitationally together.arrow_forward
- Does observed gravitational lensing correspond to a converging or diverging lens? Explain briefly.arrow_forwardFalling into Gargantua part I: Why does Gargantua appear the way it does? Because it has two accretion disks, a horizontal and a vertical one. The vertical halo is the light of the accretion disk on the far side lensed by the gravity of the black hole. Because that’s the way the art director wanted. Falling into Gargantua part II: What would Cooper’s view be of the rest of the universe as he falls across the event horizon of the black hole Gargantua? Nothing - he would no longer be able view the rest of the universe He would see the future history of the universe unfold as his field of view shrinks to a bright spot He would observe a time reversed history of the cosmos as his field of view shrinks to a bright spot.arrow_forwardExplain how and why Hubble’s observations showed that the universe is expanding?arrow_forward
