What does the cosmic microwave background tell us? An image of the cosmic microwave background radiation, taken by the European Space Agency (ESA)'s Planck satellite in 2013, shows the small variations across the sky.(Image credit: ESA and the Planck Collaboration) The CMB is useful to scie...
However,MONDand similar theories struggle to explain all of the evidence, especially the detailed patterns in the cosmic microwave background and gravitational lensing. That's why most scientists still think dark matter is a real substance — one we just haven’t been able to detect directly yet...
What is the coldest place in the universe? The coldest place in the universe is the Boomerang Nebula (1 degree K). It is the only object scientists have discovered with colder temperatures than the Cosmic Microwave background — the background radiation or background grow left by the ...
We give a brief review of the physics of acoustic oscillations in Cosmic Microwave Background (CMB) anisotropies. As an example of the impact of their detection in cosmology, we show how the present data on CMB angular power spectrum on sub-degree scales can be used to constrain dark energy...
Astronomers have detected low-level radiation scattered throughout the universe, called the cosmic microwave background radiation. When was it believed to be formed, and what does it tell us about the universe? If there is no dark matter, in order to explain our observations, our concepts of ...
The Webb has peered back about as far as is possible and found something that…..shouldn’t exist. According to existing cosmological theories, the universe is about ??13.787 billion years old. This is determined by the cosmic microwave background radiation and the universe’s expansion rate, ...

But the compelling evidence didn't come until the advent of techniques like weak gravitational lensing and the ability to read the cosmic microwave background (CMB) radiation. In effect, gravitational lensing produces an extremely large-scale version of watching light bend around our invisible black...
The universe has been expanding and evolving since its origin, approximately 13.8 billion years ago, according to current scientific understanding. The cosmic microwave background radiation provides evidence of the universe's rapid expansion from a hot, dense state. 8 Space The study of space has ...
