Edwin Hubble & Albert Einstein

Edwin Powell Hubble (November 20, 1889 – September 28, 1953) was an American astronomer who played a crucial role in establishing the field of extragalactic astronomy and is generally regarded as one of the most important observational cosmologists of the 20th century. Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of General Relativity, effecting a revolution in physics. 5.0/5

Hedgehog or Fox? Scientists come in two varieties, hedgehogs and foxes... foxes know many tricks, hedgehogs only one. Foxes are broad, hedgehogs are deep. Foxes are interested in everything and move easily from one problem to another. Hedgehogs are only interested in a few problems that they consider fundamental, and stick with the same problems for years or decades. Most of the great discoveries are made by hedgehogs, most of the little discoveries by foxes. Science needs both hedgehogs and foxes for its healthy growth, hedgehogs to dig deep into the nature of things, foxes to explore the complicated details of our marvelous universe. Albert Einstein and Edwin Hubble were hedgehogs. Charley Townes, who invented the laser, and Enrico Fermi, who built the first nuclear reactor in Chicago, were foxes. — Freeman Dyson In 'The Future of Biotechnology', A Many-Colored Glass: Reflections on the Place of Life in the Universe
Found: A Corner of the Cosmos -nice article on the Yerkes Observatory, the largest refracting 40in telescope For the entirety of human history, we have been fascinated by the stars and planets that dot the sky. It’s only recently that we have been able to get close to space and begin to understand its amazing properties. When I first saw this 1919 picture of nebulae in the Pleiades, I was surprised to see such an old photograph of distant stars. To think that an image like this was published just a year shy of the end of the first World War and over 40 years before the first man stepped foot in outer space seems almost beyond comprehension. The image was taken at the Yerkes Observatory in Williams Bay, Wisconsin. Yerkes has the largest refracting telescope—all glass lenses, no mirrors—in the world. It also has been the home for numerous astronomical discoveries and a place of research for famous individuals such as Edwin Hubble, Carl Sagan and Albert Einstein (pictured below). Yerkes was founded in ...
WASHINGTON: Scientists have found out why physicist Albert Einstein, who for long believed that the universe was static, changed his mind and accepted the modern cosmological view that the cosmos is expanding. Until 1931, the 20th century genius, Einstein believed that the universe was static rather than expanding. An urban legend attributes this change of perspective to when American astronomer Edwin Hubble showed Einstein his observations of red shift in the light emitted by far-away nebulae - today known as galaxies. But the reality is more complex, researchers said. The change in Einstein's viewpoint, in fact, resulted from a tortuous thought process, said researchers in an article published in the European Physical Journal H. Harry Nussbaumer from the Institute of Astronomy at ETH Zurich, Switzerland, explained how Einstein changed his mind following many encounters with some of the most influential astrophysicists of his generation. In 1917 Einstein applied his theory of General Relativity to the un ...
Astronomy Ireland New Year Lecture 'Einstein and the Expanding Universe' Tonight at 8pm in Trinity college Dublin Where did it all come from? Why are there stars, planets, and galaxies? What was the Big Bang? How will the Universe eventually end? Almost 14 billion years ago the entire Universe was extremely small and hot, and it began to rapidly expand. This event is known as the Big Bang. As the Universe grew, it gradually cooled down enough to allow energy turn into matter and light as we know it now, which in turn formed the first stars and galaxies. We know this happened because we can see the Universe still expanding: our telescopes can spot distant galaxies rushing away at great speeds. The discovery by Edwin Hubble in 1929 of a linear relation between the redshift of the spiral nebulae and their distance marked one of the great advances of 20th century astronomy. A number of theoreticians interpreted the discovery as evidence for a universe of expanding radius, including Albert Einstein. In this ta ...
Top 10 Scientific Laws and Theories that you Should Really Know.. 10.Big Bang Theory If you're going to know one scientific theory, make it the one that explains how the universe arrived at its present state. Based on research performed by Edwin Hubble, Georges Lemaitre and Albert Einstein, among others, the Big Bang Theory postulates that the universe began almost 14 billion years ago with a massive expansion event. At the time, the universe was confined to a single point, encompassing all of the universe's matter. That original movement continues today, as the universe keeps expanding outward. The theory of the Big Bang gained widespread support in the scientific community after Arno Penzias and Robert Wilson discovered cosmic microwave background radiation in 1965. Using radio telescopes, the two astronomers detected cosmic noise, or static, that didn't dissipate over time. Collaborating with Princeton researcher Robert Dicke, the pair confirmed Dicke's hypothesis that the original Big Bang left behind ...
Q:- Who gave the first evidence of the Big-Bang theory?. (A) Edwin Hubble. (B) Albert Einstein. (C) S. Chandrasekhar. (D) Stephen Hawking
I know some of you would not be interested in what I have to say, but i'd like to take a moment to show appreciation to all leading men of science to whom we owe a great thanks. They helped shaped the world as we know it by sacrificing their time, families and lives for the purpose of evolution and progress. Among these distinguished men are Isaac Newton, Albert Einstein, Neils Bohr, Charles Darwin, Sigmund Freud, Galileo Galilei, Antoine Laurent Lavoisier, Johannes Kepler, Nicolaus Copernicus, Michael Faraday, James Clerk Maxwell, Claude Bernard, Pierre Simon de Laplace, Edwin Hubble , Joseph J. Thomson, Leonard Euler, Erwin Schrodinger, Richard Feynman, Carl Sagan, Stephen Hawking and many more. Don't take anything for granted. End the violence and wars. These are people you should consider as leaders. They lead you to the future, war criminals lead you to the past...
California is about to pass a law banning smoking in your own home. Here's a short list of people who won't be welcome in California; Albert Einstein, Paul Mccartney, Winston Churchill, George Orwell, Thomas Edison, Franklin D. Roosevelt, Robert Oppenheimer, Edwin Hubble, Oscar Wilde, Sartre, Tolkien, J.K. Rowling, Mark Twain, Albert Camus, Bertolt Brecht, Kurt Vonnegut, stop me when you think I've made my point here, Johnny Cash, Vincent van Gogh, Alfred Hitchcock, Maurice Ravel, Renoir, Picasso, Igor Fyodorovich Stravinsky. If you're too thick to get what I'm trying to say it's that a lot of very creative people smoke. A lot. You want to forgo any accomplishments they make because you don't like it? Really? Stop making smokers pariahs or we'll start taxing you by the pound. Btw? I don't smoke.
Hubble’s Law For thousands of years, astronomers wrestled with basic questions concerning the universe. Until the early 1920’s, it was believed that the universe had always been in existence; also, that the size of the universe was fixed and not changing. However, in 1912, the American astronomer, Vesto Slipher, made a discovery that would soon change astronomers’ beliefs about the universe. Slipher, noticed that the galaxies were moving away from earth at huge velocities. These observations provided the first evidence supporting the expanding-universe theory.[1] Before the invention of the telescope in 1608, man could do little more than wonder about the origin of the universe. (Courtesy: NASA) In 1916, Albert Einstein formulated his General Theory of Relativity that indicated that the universe must be either expanding or contracting. Confirmation of the expanding-universe theory finally came in 1929 in the hands of the well known American astronomer Edwin Hubble. By observing redshifts[2] in ...
