Yes. Cosmic background microwave radiation was the "smoking gun" for the idea of the Big Bang. Let's look. Jump with me.
As telescopes became more advanced and observers were more able to "see" the universe, it became apparent that things were moving "away" from earth and its environs. And the farther we looked and were able to see objects, the faster those objects were moving away from us. Simple. Now rewind the film. Things are getting closer and the universe is getting "smaller" as we roll back the clock. If we roll it back far enough, there was a time when everything was "smooshed together" before it went out and "apart" like it's doing. It must have "blown up" to get everything to end up going away from everything else, which it is. Big Bang theory. We good? Let's jump again.
There was a "big bang" and space-time was created and all this stuff began scattering like so much shrapnel from a bomb. The universe was "really small" compared what it is today, and all that matter and energy were crammed in there. It was hot beyond belief. The energy dispersed and matter began to form from the energy. Everything was still beyond the temperature in stars. But it was cooling. As the matter continued to form, the universe cooled more. Stuff spread out more and the universe got cooler and the cycle continued. Really high energy gave way to lower and lower energy, and eventually to the point where only an "afterglow" remained - microwave cosmic background radiation.
Big Bang was proposed way back in the 1920's. And the thinking was, "Gosh, if there was a big bang, what is left from the bang?" It wasn't until 1965 that a couple of guys from Bell Labs who were doing microwave experiments found this radiation. Point a microwave antenna in just about any direction and it's there, a little whisper or echo of the "blast" that was Big Bang.
Because of the big bang our universe was created.
What else can I help you with?
The discovery of cosmic microwave background radiation and primordial helium gas was scientific evidence supporting what theory?
The 'big bang' theory.
This theory lost its appeal when astronomers discovered quasars and cosmic background radiation?
In Cosmic Physics for $1000, Alex, "What is the Steady State Universe?"
Which statements are true regarding the scientific evidence supporting the big bang theory?
Researchers found the "cosmic microwave background radiation", which is a heat imprint left over from the big bang. The redshift of light emitted by most galaxies indicates the universe is expanding.
What are two pieces of evidence of the big bang and that the universe is expanding?
1) Red shift seen in all distant galaxies, whose size is propotional to the galaxy's distance from us. 2) Existence, isotropy, and spectrum of the cosmic microwave background radiation.
What theory explains that universe began in a violent explosion?
The big bang theory does not actually begin with a "violent explosion." Instead, there was neither medium, light, nor sound in the initial moments. Instead, there was just a rapidly expanding ripple of rapidly cooling energy contained within a bubble of space-time. Eventually matter synthesized from this energy, crystallizing into hydrogen gas through which electromagnetic radiation could permeate. This radiation has been detected as the cosmic microwave background, or CMB. About that time the universe would have rung like a bell as sound energy would have propagated through it. We have detected sound waves bleeding energy off stars within sufficiently dense nebular, so we know this phenomenon is real, and interesting.
Which theory is supported by the evidence of cosmic microwave backround radiation?
The evidence of cosmic microwave background radiation supports the Big Bang theory.
Which of these is evidence that supports the big bang theory?
cosmic microwave background radiation
The discovery of cosmic microwave background radiation and primordial helium gas was scientific evidence supporting what theory?
The 'big bang' theory.
Which theory of the universe did the 1964 discovery of cosmic microwave background radiation support?
The 1964 discovery of cosmic microwave background radiation supported the Big Bang theory of the universe. This radiation is considered a remnant of the early stages of the universe when it was hot and dense, aligning with the predictions of the Big Bang model.
What discovery destroyed the steady state theory?
The discovery of the cosmic microwave background radiation in 1965 by Penzias and Wilson provided strong evidence in support of the Big Bang theory, contradicting the predictions of the steady state theory. The steady state theory proposed a continuous creation of matter to maintain a constant density of the universe, but the presence of the cosmic microwave background radiation was better explained by the rapid expansion and cooling of the universe after the Big Bang.
What evidence was used to develop the big bang theory?
The red shift and the cosmic microwave background radiation was the evidence used to develop the big bang theory.
Why was the COBE important to the big bang theory?
NASA's COBE (Cosmic Bakground Explorer) satellite was developed to measure the cosmic microwave background radiation from the early Universe to the limits set by our astrophysical environment. The cosmic microwave background radiation is a remnant of the Big Bang. Study of minute temperature variations are linked to slight density variations in the early universe. These variations are believed to have given rise to the structures that populate the universe today: clusters of galaxies, as well as vast, empty regions.
What are the 2 terms to support the big bang theory?
1) Cosmic Microwave Background Radiation 2) The universe is very quickly expanding
What is spectral distribution of cosmic microwave background radiation?
The spectral distribution of cosmic microwave background radiation follows a blackbody spectrum with a temperature of approximately 2.7 Kelvin. It peaks in the microwave region of the electromagnetic spectrum, with a characteristic wavelength of around 1 mm. This radiation is considered a key piece of evidence supporting the Big Bang theory.
What did Penzias and Wilson discover?
Penzias and Wilson discovered the cosmic microwave background radiation in 1965, providing strong evidence for the Big Bang theory of the origin of the universe. This discovery earned them the Nobel Prize in Physics in 1978.
What is the significance of the temperature 2.7 Kelvin in the study of cosmic microwave background radiation?
The temperature of 2.7 Kelvin is significant in the study of cosmic microwave background radiation because it represents the remnant heat from the Big Bang, providing crucial evidence for the Big Bang theory and helping scientists understand the early universe's evolution.
What is cmb?
CMB stands for Cosmic Microwave Background, which refers to the faint radiation left over from the Big Bang. It is the oldest light in the universe and provides important clues about the universe's origin and evolution. Scientists study the CMB to learn more about the composition, age, and structure of the universe.
