Re-budgeting


No, not dollars.  Energy.  And I’m not talking about oil futures.

Astronomers now estimate that out of the total mass-energy  in the universe, 74% to 76% is dark energy, 20% to 22% is dark matter and 4% is ‘normal’ (baryonic) matter/energy (remember, ‘normal’ matter and ‘normal’ energy are related by the famous equation E=Mc^2).  It’s the last bit that makes stars, planets and everything we see.

So, 94% to 98% of the universe we simply can’t see.

  1. So we are made of matter that makes up 94% to 98% of the universe. Doesn’t that make dark matter “normal” matter and baryonic matter (and us cause its what we are made of) the “abnormal” matter?
    I guess that makes us freaks.

  2. Duality of light. Intensity of the electromagnetic. Component can be considered mass
    conversion E=mc^2 and where E=hf can it be said that
    hf=mc^2 thus hf/c^2=m?

  3. So we are made of matter that makes up 94% to 98% of the universe.

    How do I miss that crap?
    Correction: “So we are made of matter that makes up 2% to 6% of the universe”
    I is dumb.
