Whether the Universe will 'end' at all is not certain, but all evidence suggests it will continue being humanity's cosmic ...
A new study casts doubt on the universe’s accelerating expansion, suggesting dark energy might be weakening over time.
Scientists have captured the first-ever direct evidence for dark matter, the elusive substance that makes up more than a ...
Research published Tuesday by a Japanese astrophysicist says that gamma rays may have been generated by the collision of dark ...
Our Solar System orbits the galactic center at an estimated 792,000 kilometers per hour, taking 225 million Earth years to ...
A team of international physicists has delivered a striking challenge to one of the most provocative ideas in modern science: ...
What the researchers found, grimly, is that the universe has gotten gradually colder. Ten billion years ago, the average dust grain temperature in the sampled galaxies was warmer by about 10 degrees ...
Physicists explore whether the universe hides extra dimensions. These tiny, curled-up or warped dimensions could explain ...
In a cafe at CERN in 1992, three physicists realized they disagreed about how many constants are needed to describe all of nature. A recent paper suggests only one – time – is necessary.
The universe is looking younger every day, it seems. New calculations suggest the universe could be a couple billion years younger than scientists now estimate, and even younger than suggested by two ...
