Improved Hubble data provide fresh evidence for new physics

Measurements made by the European Space Agency’s Planck satellite, which maps the cosmic microwave background, predicted that the Hubble constant value should now be 67 kilometers per second per megaparsec (3.3 million light-years), and could be no higher than 69 kilometers per second per megaparsec. This means that for every 3.3 million light-years farther away a galaxy is from us, it is moving 67 kilometers per second faster. But Riess’s team measured a value of 73 kilometers per second per megaparsec, indicating galaxies are moving at a faster rate than implied by observations of the early universe.

Trouble Detected in Infamous Dark Matter Signal

New results from a decades-old experiment were initially touted as further evidence for dark matter. But independent scientists have cast serious doubt on that claim, leaving most everyone puzzled.
