How does the expansion of the universe affect light? How does redshift prove the universe is expanding? According to the big bang theory, approximately when did the universe begin? What does the Big Bang nucleosynthesis explain? What is the relationship between the big bang theory and dark ener...
How does a redshift give evidence to the Big Bang Theory? How was CMB radiation first discovered? How does redshift prove the universe is expanding? What is cosmological redshift? How does redshift and blueshift support the big bang theory? How was dark energy discovered? How was the speed...
Today, the universe continues to expand, and astronomers have evidence to prove it. Up next, we're going to examine some of that evidence. Evidence for the Big Bang If the big bang theory is correct, then astronomers should be able to detect the expansion of the universe. ...
But before we get to that, let’s take a look at how “material” – physical matter – first came about. If we are aiming to explain the origins of stable matter made of atoms or molecules, there was certainly none of that around at theBig Bang– nor for hundreds of thousands of y...
This is why cosmologists speak of redshift as a function of distance in both space and time. The light from these distant objects has been traveling for so long that, when we finally see it, we are seeing the objects as they were billions of years ago. ...
But infrared observation is essential to understanding the universe. Dust and gas can block the visible light of stars in stellar nurseries, but infrared passes through. Moreover, as the universe expands and galaxies move apart, their light "stretches out" and becomes redshifted, sliding toward ...
the change in frequency of light or sound emitted by a moving object that in the astronomical world manifests as the so-calledredshift, the shift towards "redder", longer wavelengths in objects speeding away from us. In a leap of intuition, Rømer determined that light was taking measurable...
If light obeyed the normal addition of velocities, then the speed of the light beam that pitching great Walter Johnson saw should now be 1.8c as seen by someone watching from beside the train tracks (the c Walter saw, plus the 0.8c of the...
