Solution

The correct option is D Edwin Hubble
Edwin Hubble discovered that the galaxies are drifting away from one another and that the distance between them and the speed of their separation are in direct proportion. He played a crucial role in establishing the fields of astronomy and observational cosmology and is regarded as one of the most important astronomers of all time.

I am sorry to ask my question out of syllabus. My question is:

We know that the universe is expanding rapidly. Every star and planet is going away from one another faster than the speed of light! Then why it is said that our Galaxy (Milky way Galaxy) is coming nearer to our neighbour galaxy (Andromeda Galaxy) and after many years, these galaxies will collide with each other?

Q. Hubble’s law can be stated in vector form. Outside the local group of galaxies, all objects are moving away from us with velocities proportional to their positions relative to us. In this form, it sounds as if our location in the Universe is specially privileged. Prove that Hubble’s law is equally true for an observer
elsewhere in the Universe. Proceed as follows. Assume we are at the origin of coordinates, one galaxy cluster is at location and has velocity relative to us, and another galaxy cluster has position vector and velocity Suppose the speeds are nonrelativistic. Consider the frame of reference of an
observer in the first of these galaxy clusters.
