A short history of Dark Energy

clipped from christophergovanstreet.blogspot.com Edwin Hubble discovered in 1929 that the universe seems to be expanding The tool the team would be using was a specific type of exploding star, or supernova, that reaches a roughly uniform brightness and so can serve as what astronomers call a standard candle The rate of the expansion of the universe was not slowing down. Instead, it seemed to be speeding up. Michael Turner called this antigravitational force "dark energy." Dark energy does it change over time and space? quintessence Does it not change? In that case, they'll call it the cosmological constant, a version of the mathematical fudge factor that Einstein originally inserted into the equations for relativity universe that is 22 percent dark matter, 74 percent dark energy and 4 percent the stuff of us Take the observations of supernovae, apply the other cornerstone of 20th-century physics, quantum theory, and you get gibberish — you get an answer 120 orders of magnitude larger than .74 many universes? 10 raised to the power of 500
