Some thoughts on mass

F = (Gm₁m₂)/r², is the force of attraction between two bodies with masses m₁ and m₂ and r being the distance between them.

1. So when two bodies are brought sufficiently close together (such that r becomes very small), the force of attraction will be very large. This force will pull them closer. So masses does have a tendency to combine.
2. Two masses always attract each other. The universe is full of masses, but ever expanding why??

nature of time

It is said that Einstein once thought...

What if time were circular?

The beginning would have followed the end...:)
