I was thinking about dark energy and whether current understanding puts its distribution as being everywhere in the Universe and evenly so? Like the CMB but homogenous and non fluctuating? I understand that 'dark matter' clumps around certain areas of our own Milky Way so it is quite unlike dark energy. If dark energy is the accelerating force of the Universe to which we owe our current accelerated rate of expansion and its distribution is homogenous and everywhere, can one imagine it exists in your room right now and in your very body, slowly accelerating you outwards, as it were? Far fetched, maybe. I am simply trying to grasp what it means on a personal level as opposed to the more common uses in Cosmology. Is everything simply expanding a tiny bit? You in your chair, your speakers on your desktop, your oaken table and that ruler on your notebook. And if your rule is expanding too, how can one use it to measure the expansion of your speakers? If anyone knows how dark energy was derived, that would be great too. My guess is it was a necessary number coming out from observation of distant galaxies accelerating outwards faster than predicted given hubble's constant? Thanks.
