a mysterious repulsive force that appears to be
causing the expansion of the universe to accelerate
Type Ia supernovae as standard candles; Hbl law
dark energy + evidence
says they should be moving faster there; inverse
square law for light dictates that dimmer = farther;
calculated dstncs to things are even farther than
their redshift predicts; they are being pushed away
matter (gravity, attractive force) that does not give
off electromagnetic radiation but is quite abundant
in the universe
dark matter + evidence
rotation curves, ultra-faint galaxies, gravitational
lensing, Coma Cluster + Zwicky, Bullet Cluster
high density + high heat needed
proton-proton chain P + P -> H2 + e⁻ + neutrino
H2 + P -> He3 + gamma ray
He3 + He3 -> He4 + 2P

the process by which radioactive isotope breaks
down into a stable isotope of same/another
radioactive decay
element; each half-life leaves half of existing
population of radioactive isotope
gravitationally bound stars formed from the same
gas cloud; all about same dstnc from Earth, all
star cluster + special
about same age; open clusters have countable
properties
stars, globular clusters have too many to count
(stable for like, ever with that much gravity)
measuring the distance to a star cluster by
comparing the apparent brightness of the cluster's
main sequence fitting
main sequence with that of the standard main
sequence
inert core of dead red giant; stable size due to
white dwarfs + special degeneracy pressr, DENSE (Earth size, Sun mass),
properties can't generate new energy, cool off, gradually grow
fainter
plots logarithmic relatnshp btwn cepheids' varblty
period-luminosity pd length and abs L; given abs L + apparent L, we
diagram can estimt dstnc to cepheid + of obj in which it
resides
variable star w/ irregular varblty trend, rapidly
brightening, fading progressively slower till 3/4
cepheid variable stars down, then rapidly finishing/repeating; variatn
related to intrinsic luminosity, i.e. their size/temp
changing
why we consider universe cosmological principle; stuff would be moving away
expanding rather than from the center, and stuff is moving away from us,
things just moving which would make us the center, which we know we
through it aren't
