The Cosmic Microwave Background (CMB) radiation, a remnant of the Big Bang, provides a snapshot of the universe at approximately 380,000 years old, when it became transparent to light. Three ...
The cosmic microwave background (CMB) is the radiation allowed to freely propagate after the universe cooled enough for electrons to combine with atomic nuclei to form neutral atoms some 300,000 ...
The cosmic microwave background (CMB) is primeval radiation emitted shortly after the Big Bang. Regarded as an 'echo' of the Big Bang, CMB fills the universe.
The CMB as we detect it today has been stretched to its current microwave wavelength due to the universe’s expansion, and cooled to a temperature of just 2.7 K. Hot and cold At first glance, the CMB ...
We analyze the CMB temperature anisotropies generated by a single-mode adiabatic superhorizon perturbation. We show that an adiabatic superhorizon perturbation in a LCDM universe does not generate a ...
What Planck saw: does the cosmic microwave background harbour evidence for loop quantum cosmology? (Courtesy: ESA and the Planck Collaboration) A theory of quantum gravity that describes the universe ...
