      Roughy 25% of our universe is made of dark matter and quite a sizable chunk of the rest is energy.

      Around 70% of the universe is made of Dark energy (not dark magic)… Dark energy is a supposed form of energy that acts in opposition to gravity and therefore.

      How strange is it that universe is composed of a theoretical energy? So much as to be discovered. Are you interested in space and astronomy?

      Woah – this is way outside my knowledge-base! But I can Google, and it’s interesting – thanks for the question! Apparently the universe is made of:
      1) matter (30%)
      2) energy (70%)
      and most of the matter is “dark matter”, so:
      1a) matter (non-dark): 5%
      1b) dark matter: 25%
      2) energy (70%)
      We can’t see dark matter (only its effects), and apparently we don’t know what it is either!
