What Is At The Center of The Universe?

You are.

This profound thought occurred to me as I went to bed the other day falling into this weird mixture of reality and dream, with nonsensical endings progressively taking over the sensible thoughts with the rational brain slowly but surely sidelined on the autobahn into the dreamworld. This funny experience picked up after Corona and I am not entirely sure its a good thing. But it generates interesting ideas.

The logic though, is sound and simple. The concept of universe, after all, is, and will ever be, connected to the concept of “observable” universe, since what cannot be “observed” in that astronomical sense is indistinguishable from non-existing. For all intents and purposes, what is outside of observability zone does not exist for us. At same time, we have no indication that outside of that zone there is indeed nothing; it is possible that the universe continues endlessly. A hypothetical humanoid colony 10 billion light years from ours will be at the center of their own “observable” universe, and it will be different from ours. Both are thus at the center of their own respective universes. In that sense, we are special – and we are not, at the same time 🙂

The NASA/ESA Hubble Space Telescope has captured this vivid image of spiral galaxy Messier 77 — a galaxy in the constellation of Cetus, some 45 million light-years away from us. The streaks of red and blue in the image highlight pockets of star formation along the pinwheeling arms, with dark dust lanes stretching across the galaxy’s starry centre. The galaxy belongs to a class of galaxies known as Seyfert galaxies, which have highly ionised gas surrounding an intensely active centre.
