Q5

Q5 asks whether our current understanding of the universe suggests that its total energy is zero—the idea that the positive energy from matter and radiation is exactly balanced by the negative energy of gravity. This concept helps explain how the universe could have begun from "nothing," as these opposing energies cancel out, allowing for a spontaneous origin without violating conservation laws. In essence, it proposes that the universe's total energy sums to zero, providing a plausible framework for its existence and large-scale structure.
