Our ideas about the universe are based on a century-old simplification known as the cosmological principle. It suggests that when averaged on large scales, the Cosmos is homogeneous and matter is distributed evenly throughout.

This allows a mathematical description of space-time that simplifies the application of Einstein’s general theory of relativity to the universe as a whole.

Our cosmological models are based on this assumption. But as new telescopes, both on Earth and in space, deliver ever more precise images, and astronomers discover massive objects such as the giant arc of quasars, this foundation is increasingly challenged.

SpaceX has announced a plan to give T-Mobile customers direct access to the Starlink satellite constellation, ensuring they’ll have mobile coverage nearly everywhere in the US.

“I think this is really a massive game changer,” said SpaceX CEO Elon Musk during a live event at SpaceX’s Starbase facility in Texas. “In a nutshell, it’s no more dead zones.”

The challenge: Cell coverage is widespread in the US, but there are still more than half a million square miles — nearly twice the size of Texas — where you won’t find a signal from any carrier.

CAPE CANAVERAL, Fla. — A European space telescope blasted off Saturday on a quest to explore the mysterious and invisible realm known as the dark universe.

SpaceX launched the European Space Agency’s Euclid observatory toward its ultimate destination 1 million miles (1.5 million kilometers) away, the Webb Space Telescope’s neighborhood. It will take a month to get there and another two months before it starts its ambitious six-year survey this fall.

Flight controllers in Germany declared success nearly an hour into the flight, applauding and shouting “Yes!” as the telescope phoned home after a smooth liftoff.
