Nothing is unphased fluctuations. Here’s how we derive the rule: Later, we will consider that we can derive e = mc2     from  ke = 1/2mv2. so,  something happens that allows all of this stuff to happen. all of this stuff being the innumerable galaxies.  seen in every direction. ke = mgH when H = λ, amplitude = wavelength, and  hc/λ = mgH.  positive energy = negative energy so, the universe can be. so the universe is.
