Scientists know the universe is expanding because of the A. blue shift of distant galaxies. Ask your question. We need you to answer this question! This is usually interpreted as a result of the Doppler effect - i.e., the galaxies are moving away from us. Although the universe is expanding all around us, the expansion happens over such a large scale that it's very hard to notice it from Earth. 1.

The galaxies are moving away from each other, and the temperatures are increasing. The expansion of the universe was discovered in 1929 by American astronomer Edwin Hubble. But over the last 13.8 billion years, the Universe has been continually expanding – and at first it did so very rapidly.

Spell. Now, a team of scientists led by Professor Subir Sarkar of Oxford University's Department of Physics has cast doubt on this standard cosmological concept. The branch of science that deals with the Universe and the various objects, like stars, planets, and galaxies, that we find within it. Scientists believe that the universe is expanding at an ever increasing rate. 1) The universe is expanding and celestial objects are moving away from each other at an increasing rate. 14. Effect shows stars with red shifted light D the Doppler effect shows stars with green light It was during the 1920's that Edwin Hubble provided the first evidence that we live in an expanding Universe. Photo taken by the Hubble Space Telescope External. How do we know the universe is expanding? Learn. We still don't know why or how the universe is accelerating, but the leading theory is that there's some kind of energy—scientists call it 'dark energy'—pushing everything apart. The galaxies outside of our own are moving away from us, and the ones that are farthest away are moving the fastest.
