Question
(a) Use the Heisenberg uncertainty principle to calculate the uncertainty in energy for a corresponding time interval of $10^{-43}\textrm{ s}$ . (b) Compare this energy with the $10^{19}\textrm{ GeV}$ unification-of-forces energy and discuss why they are similar.
1. $3\times 10^{18} \textrm{GeV}$
2. $0.3$
