How fast is the universe expanding in mph?
Measurements made using the cosmic microwave background (CMB), a remnant from the Big Bang that provides a snapshot of the infant universe, suggest that the Hubble constant is 46,200 mph per million light-years (or, using cosmologists’ units, 67.4 kilometers/second per megaparsec).
Did the universe expand faster than light?
And it certainly did. That was during the epoch of inflation, during the first split-second of the Universe’s existence, when the expansion of the Universe occurred at a rate that was effectively far faster than the speed of light.
Is the universe expanding at an increasing or decreasing rate?
The number indicates that the universe is expanding at a 9% faster rate than the prediction of 67 kilometers (41.6 miles) per second per megaparsec, which comes from Planck’s observations of the early universe, coupled with our present understanding of the universe.
