“The most commonly quoted mass for the vacuum is 1094 grams per centimeter cubed (g/cm3) as calculated by John Wheeler who was quoted above.11 We will calculate later that the energy of the vacuum is 1095 g/cm3 by a slightly different method, so that value will be used from here on. As we will see, one order of magnitude difference is not that significant at this point in our discussions. Energy is related to mass by the well-known relation E=mc2. For comparison water has a mass density of 1 g/cm3 by definition. It is impossible for most normal people to grasp just how big a difference in energy there is between the zero-point field and water, so perhaps a simple illustrative example will help. Let’s start with the clichéd drop in a bucket. If the drop is one milliliter (1 ml) and the bucket 100 liters (72.5 gallons), then that gives us a factor of 105. If instead we consider a drop in all the Earth’s oceans, then we have a factor of 1024. That is a lot bigger than a bucket but nowhere close to how insignificant the mass of the drop of water is when compared to zero-point energy. To continue, what if the ocean was the size of the sun? That gives us a ratio on the order of 1041, which is still a long way off. If the ocean was the size of the solar system we get a ratio on the order of 1050. Now if we expand the ocean to the size of the galaxy we get ~1076 and we are still not anywhere close. What if the ocean is the size of the known visible universe? Assuming a radius of 7.4 x 1026 meters the mass ratio is 5 x 1095. There we go. So, the density of water compared to the energy of the vacuum is equivalent to five 1 ml drops of water in an ocean the size of the visible universe. Since we are mostly water and have a similar density to water, the vacuum fluctuations inside our body are like having all the mass-energy of an ocean of water the size of the universe inside each little part of us. Wow, we are pretty insignificant in the big scheme of things and so is any other body of solid matter or any amount of energy associated with it. This zero-point energy is all around us and all throughout us. We are lucky that zero-point energy is not detectable or anything we did would be undetectable noise to any sensor we could possibly make. Even worse, if we could absorb even a small fraction of that energy, we would be vaporized in an instant. Or, if all that energy participated in a gravitational force, the universe would be crushed to a speck.”
