I love working on GPUs. Whether it is Graphics or HPC.

comment Does the amount of gravitational potential energy in the universe increase as it expands?
Negative sign is always relative. Just like relative speed.

@roblev As the distance between masses increases, the potential energy between them decreases. E=Gmm/r

comment Are the field lines the same as the trajectories of a particle with initial velocity zero
Yup. I am sure that it is from that book. What explained is same as the path of unit positive charge in an electric field. Put q1=1 in the force equation (force between 2 charges). The electric field can be defined in alot of ways. As you have mentioned 'particle with initial velocity zero', i have taken charges to explain it. Else, to understand the fields, what you have told is true.

There are a lot of ways to define Electric Field. I explained it in the lamest way. I am sure i am right. You can refer to Feynman lecture on Physics part 2 for more info (about my answer).
