A new study suggests that failing to detect dark matter signals in some galaxies may not contradict evidence seen in our own.
The new paper concludes that when space is treated as physically real rather than empty, the need for dark matter, dark ...

In the chaotic first moments after the Big Bang, ripples in spacetime may have done more than just echo through the ...
A tiny object half a universe away, a scar in a stream of stars circling the Milky Way, and an unusual star cluster in a ...
A growing mystery in astronomy is the presence of gargantuan black holes—some weighing as much as a billion suns—existing ...
New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could ...
