Perhaps Dark Energy and Exotic Dark Matter are new terms for your personal science knowledge inventory.
If so, and you want an update, use the DOOR.
From Hugh Ross’s Why the Universe Is the Way It Is (Baker, 2008, p. 37) is Table 2.1, “Inventory of All the Stuff That Makes Up the Universe.”¹ A glance at “Planets,” the last item may raise your eyebrows.
_____Cosmic component Percentage of total cosmic density
Dark energy (self-stretching property of cosmic
space surface) 72.1
Exotic dark matter (particles that weakly interact with
ordinary matter particles and light) 23.3
Ordinary dark matter (particles that strongly interact
with light) 4.35
Ordinary bright matter (stars and star remnants) 0.27
Planets (a subset of ordinary dark matter) 0.0001
¹ The stuff you and I are most familiar with I’ve put in green. Our knowledge of matter and energy has “recently” been taken to a new level. And dark energy? Think of stretching an elastic band. Dark energy may be thought of (not as anti-gravity as often mentioned but as) an “elastic force” that pulls outward away from the “center” where everything began. This, by the way, suggests an eventual ending of everything as everything gets to far away from everything else. Astrophysicist Ross cites Princeton cosmologists Masataka Fukugita and James Peebles collected prior to 2005, with the addition of updates made possible in 2006 and 2008 by the 2nd and 3rd releases of the Wilkinson Microwave Anisotropy Probe’s (WMAP) results.
