Web24 okt. 2016 · The find was backed up by data collected separately on things like clustering galaxies and the cosmic microwave background - the faint afterglow of the Big Bang . And earlier this year, NASA and ESA scientists found that the Universe could be expanding around 8 percent faster than originally thought. WebSo each electron gains kinetic energy equal to the amount of energy transferred electrically. The electron starts from rest (near enough) so the kinetic energy gained is given by ½ mv 2 where m is its mass and v is its speed. So we can say that: ½ mv 2 = eV. The mass of the electron is m = 9 × 10-31 kg. The electronic charge is e = 1.6 × 10 ...
Thus an accelerating universe took a longer time to expand from 2/3 to 1 times its present size, compared to a non-accelerating universe with constant ˙ and the same present-day value of the Hubble constant.
