Conformal cyclic cosmology (CCC) is a cosmological model in the framework of general relativity and proposed by theoretical physicist Roger Penrose. [1] [2] [3] In CCC, the universe iterates through infinite cycles, with the future timelike infinity (i.e. the latest end of any possible timescale evaluated for any point in space) of each previous iteration being identified with the Big Bang ...
ACT made high-sensitivity, arcminute resolution, microwave-wavelength surveys of the sky in order to study the cosmic microwave background radiation (CMB), the relic radiation left by the Big Bang process. Located 40 km from San Pedro de Atacama, at an altitude of 5,190 metres (17,030 ft), it was one of the highest ground-based telescopes in ...
Katherine J. Mack (born 1 May 1981) [3] is a theoretical cosmologist who holds the Hawking Chair in Cosmology and Science Communication at the Perimeter Institute.Her academic research investigates dark matter, vacuum decay, and the Epoch of Reionization.
The discovery of cosmic microwave background radiation constitutes a major development in modern physical cosmology.In 1964, US physicist Arno Allan Penzias and radio-astronomer Robert Woodrow Wilson discovered the cosmic microwave background (CMB), estimating its temperature as 3.5 K, as they experimented with the Holmdel Horn Antenna.
PREMIERE Sky will premiere its upcoming Sky Original documentary “Hawking: Can You Hear Me?”, described as the human story behind one of the 20th century’s best known scientific minds ...
If the universe started with even slightly different temperatures in different places, the CMB should not be isotropic unless there is a mechanism that evens out the temperature by the time of decoupling. In reality, the CMB has the same temperature in the entire sky, 2.726 ± 0.001 K. [3]
Hawking spoke with WIRED on a wide range of topics in a new interview, directly addressing Trump's stance on climate change -- arguably unsurprising given his well known concerns over our planets ...
The Cosmic Background Explorer (COBE / ˈ k oʊ b i / KOH-bee), also referred to as Explorer 66, was a NASA satellite dedicated to cosmology, which operated from 1989 to 1993.Its goals were to investigate the cosmic microwave background radiation (CMB or CMBR) of the universe and provide measurements that would help shape the understanding of the cosmos.
