"A cosmological horizon is a maximum distance from which one could possibly retrieve information," Jake Helton, a University of Arizona astronomer who is also part of the JWST Advanced Deep ...

Our current cosmological event horizon is about 16 billion light-years away. As long as this acceleration continues, any light emitted today that is beyond that distance will never reach us.

The universe has a cosmological horizon, a limit beyond which we cannot see that is set by its finite age, light’s finite speed and cosmic expansion. But unfortunately, that’s where the ...

Cosmological holography has not yet been made mathematically precise, partly because the cosmological horizon has a finite area and grows with time. It has been claimed, ...

By measuring the angular size of this horizon on the sky, we can find the true physical distance corresponding to the galaxies on these BAO rings. With one more ingredient, that translates to an ...

According to Helton, the cosmological horizon, or the "Photon Horizon," is a sphere with a boundary around 46.1 billion light years away, a figure dictated by the universe's expansion.
