The sun's heat is distributed throughout the world by?
The sun's heat is distributed throughout the world by a process called radiation. This involves the sun emitting energy in the form of electromagnetic waves, which travel through space and warm the Earth's atmosphere and surface when they are absorbed. Heat is then further distributed through processes like conduction, convection, and ocean currents.
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.
From the cosmic background radiation scientists can infer that just after the big bang the universe must have been?
hot and dense. The cosmic background radiation provides evidence that in the early universe, all matter and energy were packed closely together and the temperatures were extremely high. This radiation is a remnant from the early stages of the universe's expansion and gives insight into its origins.
The big bang produced an imprint of leftover heat called?
Ah, yes, the big bang left behind a beautiful imprint called the cosmic microwave background radiation. This gentle glow can be seen throughout the universe, like a soft whisper from the beginning of time. It reminds us of the vast and wondrous journey that brought us to this moment.
Why is the primordial background radiation visible in all directions?
The cosmic microwave background radiation is visible in all directions because it represents the thermal radiation left over from the Big Bang. As the universe expanded and cooled, this radiation became uniform in all directions, making it observable from any location in the universe.
Did the Hubble discovery come before cosmic background radiation?
Yes
Why was cosmic background radiation an important discovery?
It is important evidence of the Big Bang.
What does the uniformity of cosmic radiation imply about its source?
The uniformity of cosmic radiation suggests that it originates from sources that are distributed evenly throughout the universe. This could point to sources such as distant galaxies, black holes, or other cosmic phenomena that emit radiation in all directions with similar intensity.
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.
Why did the discovery of background radiation with a wavelength of 7.35 cm help to support the big bang theory of the universe?
I am not entirely sure about the wavelength; however, the features of the background radiation agree very closely to what would be expected from the Big Bang theory.
The discovery of cosmic microwave background radiation and primordial helium gas was scientific evidence supporting what theory?
The 'big bang' theory.
What are two pieces of evidence that support the Big Bang theory?
Hubble's discovery in the 1920s of a relationship between a galaxy's distance from Earth and its speed; and the discovery in the 1960s of cosmic microwave background radiation.
Why was the cosmic background radition an important discovery?
The cosmic background radiation was an important discovery because it provided strong evidence for the Big Bang theory of the origin of the universe. It is a remnant of the early stages of the universe, and studying it has helped scientists understand the composition and evolution of the cosmos.
What is background microwave?
microwave background radiation is a thermal radiation left from the early stage of universe when it was much small and much hotter and filled with uniformly distributed opaque fog of hydrogen plasma
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.
The sun's heat is distributed throughout the world by?
The sun's heat is distributed throughout the world by a process called radiation. This involves the sun emitting energy in the form of electromagnetic waves, which travel through space and warm the Earth's atmosphere and surface when they are absorbed. Heat is then further distributed through processes like conduction, convection, and ocean currents.
Is there a difference between background radiation and background count rate?
There is a subtle difference. Background count rate is the measure of how strong the background radiation is.
