Within which time frame from the initial Big Bang is it felt that the present laws of physics completely fail us, because time and space as we know them did not exist? A)t = 0 to 1 s, during which time photons interchanged freely with electron-positron pairs B)t = 0 to 10^-35 s, after which the strong nuclear force "froze out" of the universe C)t = 0 to 10^-43 s, the Planck time, after which gravity "froze out" of the universe D)t = 0 to 10⁶ years, over which radiation dominated the universe

At the Planck time (t = 10^-43 s), the universe was in a state of extreme temperature, density, and energy, and our current understanding of the laws of physics breaks down. Gravity, one of the fundamental forces, is believed to have been unified with the other forces during this time, and our current theories cannot fully describe this process. Therefore, it is felt that the present laws of physics completely fail us during this time frame.
