Scientists' evidence for an expanding universe is called a because the light waves emitted by stars and galaxies are shifting toward the end of the visible color spectrum.?

Many objects observed in the universe show a red shift. It is believed that this red shift is caused by a Doppler effect - that is, that the objects are moving away from us at a significant fraction of the speed of light. If this is true, then it is evidence for an expanding universe.

Do scientists believe that continental drift is real?
Yes. They believe that the shifting of the tectonic plates under the earth caused it.
What did Hubble use to attempt to prove his theory?
he discovered that there were millions of other galaxies... making the universe unimaginably larger than previously thought. And he discovered that the light from distant galaxies is Red-shifted, and that the further the galaxy is, the more red-shifted its light. This not only demonstrated that the universe was expanding... It ultimately led to the formation of Big Bang theory by working out this expansion in reverse.
How many times has continental drift occurred?
The continents are constantly shifting. There was never a time or location that it has happened more or less. Scientists estimate that they drift 2 cm (0.8 inch) per year on average.
Shifting cultivation is mostly found in which climate region?
Shifting cultivation is done in the Tropical Rainforests
How did Edwin hubble's discovory happen?
Both.Generally most galaxies are moving apart, but some galaxies are moving towards each other. For example the Andromeda Galaxy is moving towards our galaxy, the Milky Way. The two should merge in about 2.5 billion years.
What did Edwin Powell discover?
The most important thing that Hubble discovered was that our universe is expanding. He could see this because he noticed that galaxies were moving apart (which he figured out by their red shifting). In fact, the expansion of our universe is speeding up and galaxies are moving apart faster and faster.
What did hubble conclude when he noted that light emitted from stars is shifting toward the red end of that electromagnetic spectrum?
(A) The universe is expanding.
What did Hubble conclude when he noted that light emitted from stars is shifting toward the red end of the electromagnetic spectrum?
He concluded that the universe is expanding.
How do scientists use computers to measure distance from stars?
From what I remember in two geology classes, scientists measure the distance between a star and Earth by comparing "red shift," a shifting of certain bands of light toward the "red" end of the spectrum. The further the shifting, the greater the distance.
What does earth's shifting have to do with climate change?
Absolutely nothing. Climate change is a big scam put on by dumb scientists.
Do scientists believe that continental drift is real?
Yes. They believe that the shifting of the tectonic plates under the earth caused it.
Is the shifting of orientation of a Foucault pendulum an evidence that the earth is rotating?
Yes, perhaps one of the simplest and best evidences.
What did hubble conclude when he noted that light emitted from stars is shifting towards the red end of the electromagnetic spectrum?
Whatdid hubble conclude when he noted that light emitted from stars is shifting towards the red end of the electromagnetic spectrumA. The universe is expanding
What did hubble conclude when he noted that light emitted from star is shifting toward the red end of the electromagnetic spectrum?
The obvious conclusion is that the Universe is expanding - the redshift is interpreted as a Doppler shift, therefore it seems that distant galaxies are moving away from us. This interpretation is widely accepted nowadays; there aren't any other explanations that are generally consistent with observations. I am not sure whether Mr. Hubble concluded that, but I think he did.
Why do scientists think that quakes are happening in or near Wash DC?
the plates are shifting and areas that never expierenced the in the past may become more frequent
What did Hubble conclude when he noted that light emitted from stars is shifting toward the red of the electromagnetic spectrum?
He noted that light emitted from stars is shifted further toward the red of the electromagnetic spectrum . From this he concluded that the universe was expanding.
Can astronomers infer approximately how long the universe has been expanding?
Astronomers can determine the expansion of the universe by observing the cosmic background radiation, and the red- or blue-shifting of distant objects.
