WebWe calculate the running of the scalar index in the ekpyrotic and matter bounce cosmological scenarios, and find that it is typically negative for ekpyrotic models, while it is typically positive for realizations of the matter bounce where multiple fields are present. This can be compared to inflation, where the observationally preferred models typically predict … WebThe CMB is the most perfect blackbody known. It has a temperature of about 3 degrees above absolute zero, which corresponds to a peak wavelength of about a millimeter. …
WebFor the first 380,000 years or so after the Big Bang, the entire universe was a hot soup of particles and photons, too dense for light to travel very far. However, as the cosmos … WebThe Big Bang radiation that we observe today is now in the microwave range. The total energy that was emitted from the point-like Big Bang has not changed, it has just been spread over an incredibly large sphere such that the energy per square meter is much, much less now than billions of years ago.
