Cosmic microwave background is a sea of radiation that provides us with evidence for the big bang. When around 1916 Einstein first used general relativity to build a cosmic model, he followed the ...

A paper published in 2024 theorizes that time may have existed before the Big Bang, but we're still not entirely sure.

One of the best ways to observe this era is with low-frequency radio telescopes, which can observe the “spin-flip” radiation from the hydrogen that pervades the Universe during the Cosmic Dawn.

This Cosmic Microwave Background Radiation (CMBR) is the conclusive evidence for the Big Bang theory. The 'temperature' of deep space has been measured as around 3K, not absolute zero, due to the ...

Further evidence for the Big Bang comes from the discovery of cosmic microwave background radiation (CMBR). Astronomers discovered cosmic microwave background radiation in the 1960s. The ...

We still don't fully understand what triggers lightning. A new study suggests that showers of cosmic rays may be the missing link. Cosmic rays may offer an out-of-this-world answer to a long ...

The difficulty with this, they explain, is that while lightning radio frequency signals can be mapped using ground sensors from any direction, the cosmic rays cannot. Instead, they could come from ...

Cosmic rays may play a role in triggering lightning on Earth, a new study suggests. | Credit: Jan Drahokoupil / 500px / Getty Images Cosmic rays may offer an out-of-this-world answer to a long ...

This idea of cosmic rays initiating lightning isn't new. It began in the early 1990s when it was first proposed by Russian physicist Alex Gurevich, who called it "relativistic runaway electron ...
