"This shocking result means that we now need to revisit the very foundations of everything we know about cosmology," said the reseachers.

After scientists discovered the CMB radiation in 1965, they meticulously mapped its tiny temperature variations, which displayed the exact state of the cosmos when it was a mere frothing plasma.

The CMB is radiation that fills the universe and is a leftover relic from the first few hundred thousand years of cosmic evolution after the Big Bang (for comparison, the universe is estimated to ...

However, rather than visible light, the black holes leave behind what is known as cosmic microwave background radiation, or (CMB). The idea here is that even when a universe ends and a new one ...

Using Cosmic Microwave Background (CMB) radiation instead of visible light allows scientists to determine the distribution of dark matter several billion years earlier than previously possible.

but its unique location makes it easier to discern light from cosmic microwave background radiation, also known as the CMB. About 380,000 years after the Big Bang, after the universe’s ...
