hi
my favourite chapter in a brief history of time is The unification of physicis. in which Stephen hawking has described how gravity can not be unified with all other force and what is the importance of the theory of everything. he has also said that before the end of this century we will have unified field theory.
but I don't think so
it is difficult for me to imagine that a handful of residents of a small planet circling an insignificant star of a small galaxy have as their aim of a complete understanding of the entire universe. they do not know how big is the universe. they are truly believing of comprehending the whole. which is impossible.
hope it will clear u

Hello friend!
Here's ur answer!
I liked ch-3 : expanding of universe.
In this chapter, Stephen Hawking talks about the expanding universe. The universe is getting bigger over time. One of the things he uses to explain his idea is the Doppler shift. The Doppler shift happens when something moves toward or away from another object. There are two types of things that happen in Doppler shift - red shifting and blue shifting. Red shifting happens when something is moving away from us. This is caused by the wavelength of the visible light reaching us increasing, and the frequency decreasing, which shifts the visible light towards the red/infra-red end of the electromagnetic spectrum. Red-shift is linked to the belief that the universe is expanding as the wavelength of the light is increasing, almost as if stretched as planets and galaxies move away from us, which shares similarities to that of the doppler effect, involving sound waves.
Hope it helps!! ☺
