Cosmic microwave background radiation

of our universe. 2 In short, the Big Bang theory explains how a primordial fireball expanded and cooled, and in the first few minutes synthesized helium and other light elements became transparent after 400 000 years releasing the cosmic microwave background radiation, and slowly got clumpier due to gravitational clustering, producing galaxies, stars, and planets.2 However, there is a lot of things that the Big Bang theory does not explain. For instance, why is the universe isotropic? Why is space-time

“Scientists discovered that there are microwaves coming from every direction in space. Big Bang Theory says this is energy created at the beginning of the universe, just after the Big Bang, and that has been travelling through space ever since” (BBC Stars and the origins of the Universe). This quote states that there are microwaves going in every direction in space, and that the microwaves are tied to one of the Big Bangs sayings. One of the sayings was that energy

The second evidence of the Big Bang is the Cosmic Microwave Background (CMB), which is the electromagnetic radiation left over from the time of recombination in Big Bang cosmology. It represents the first light that travelled in the universe, at the time when the first atoms were formed and the universe was transparent. The scientists Alpher and Hermann deduced that before the recombination epoch, everything was plasma and the light rays would be continually scattered by the particles they encountered

summarize the birth through mathematical theory and models of how the Big bang theory came about. Although Astronomers weren’t able to see how the universe came about, they are able to see an expansion through a phenomenon known as the cosmic microwave background which is

eventually the stars and galaxies we see today.” (Cain, 2013) The Big Bang Theory is possibly right because of the evidence/research backed up by it such as exploration done by Edwin Hubble, data found by both Arno Penzias and Robert Wilson, and background radiation that had been found that is believed to be created by the Big Bang. In the first place, Edwin Hubble was an astronomer who found important information of the BBT. His findings originated the Big Bang Theory in the first place. (“The Big Bang

The Big Bang Theory Why is the Universe expanding? What is Cosmic Background Radiation (CMB)? There are many questions asked about our Universe, which we know so little about. Scientists, in their attempt to answer these and other questions in terms of the beginning of the universe, have found one idea that seems to describe much of what we don't understand: The Big Bang Theory. Although the Big Bang Theory seems to be the best presented theory to describe the beginning of the universe, our understanding

The Discovery and Observation of the Cosmic Microwave Background: Implications for Cosmology On a spring day in late May in 1964, the future of our understanding of the universe was greatly influenced, arguable on accident. Two radio astronomers discovered something unusual, not with their eyes, but with their ears.  Arno Penzias and Robert Wilson essentially heard the buzz that the universe was echoing into their headphones, but they could not wrap their head around what it was. The two scientists

first ionized: the cosmic microwave background radiation. Since the cosmic microwave background photons were emitted roughly 380,000 years after the Big Bang, much earlier than the photons from quasars, their properties tell us about the subsequent evolutionary history of the universe. Microwave photons move freely through neutral gas, but they scatter off of ionized gas. This scattering reduces the amplitude of fluctuations in the temperature of the cosmic microwave background and produces new "polarized"

Primordial gravitational waves (GWs) are a theoretical stochastic background of gravitational radiation from the early universe which may be detected from their polarising effect on the cosmic microwave background (CMB) or by future generations of interferometers such as eLISA [1]. Able to propagate through the opaque primordial universe, they could allow us to determine the initial state of the universe as well as gaining a valuable insight into physical processes that occurred at this time. There

radio antenna to search for microwaves emitted by the Milky Way. To their surprise, they discovered a faint signal that continued to show up in their readings, no matter which direction they pointed the radio telescope. Once they considered all of the possible interferences, including cleaning pigeon feces on the equipment, Wilson and Penzias concluded that the signal in question must be real. Arno and Wilson had accidently discovered the Cosmic Microwave Background, an accident that won them the
