Week 2 - Expert Lecture

Lisa Randal is a leading physicist that has been building a theory of multiple dimensions, this theory is postulated on the idea that gravity as a force that is very weak in comparison to the other three forces. This theory states that there are multiple "Branes" of energy that would help explain why gravity is so weak a force in comparison of the other forces, she thinks that there is a heavy gravity Brane where all the remaining energy from gravity is located.

I would agree with this theory as one of the fundamental ideas of physics is that energy can not be destroyed, but only relocated to another form. If you work out the equations for the energy of gravity you come up sort, like the energy is disappearing, this makes no sense in the current ideas of physics.
