The temperature fluctuations in the CMB provide clues about the density and composition of the early universe, which in turn helps estimate its age. It’s like looking at an old photograph and ...

ACT's new measurements have also refined estimates for the age of the universe and how fast it is growing today. The infall of matter in the early universe sent out sound waves through space ...

Hubble's images have helped to pin down the age of the universe, which the expansion rate of pulsating stars suggests is some 13 billion to 14 billion years. Hubble has also captured images of ...

This is the diameter of the sphere of the “observable universe” that we find ourselves at the center of. Our ability to look out and measure the stars is limited by the age of the universe and ...

That’s 10 million times longer than the present-day age of the universe. All this means is that dark matter—whatever it is—may have arrived on the cosmic scene before the universe as we know ...

These charged primordial black holes would then have considerably extended lifetimes, many multiples of the current age of the universe. This means that those black holes could still inhabit the ...

For context, the light from the most remote galaxies recorded in the DESI catalogue was emitted 11 billion years ago, when the universe was about a fifth of its current age. DESI researchers ...
