Edwin Hubble Quotes

Equipped with his five senses, man explores the universe around him and calls the adventure Science.

In this way, Edwin Hubble worked out the distances to nine different galaxies. We now know that our galaxy is only one of some hundred thousand million that can be seen using modern telescopes, each galaxy itself containing some hundred thousand million stars.

You mean to tell me you're mourning the loss of someone who never existed?

Edwin Hubble, who continues to give me great faith in humanity, because he started out as a lawyer and then became an astronomer.

The history of astronomy is a history of receding horizons.

Science is the one human activity that is truly progressive. The body of positive knowledge is transmitted from generation to generation.

But in 1929, Edwin Hubble made the landmark observation that wherever you look, distant galaxies are moving rapidly away from us. In other words, the universe is expanding.

Equipped with his five senses, man explores the universe around him and calls the adventure science. —EDWIN P. HUBBLE (1889–1953), The Nature of Science

Observations always involve theory.

With increasing distance, our knowledge fades, and fades rapidly. Eventually, we reach the dim boundary—the utmost limits of our telescopes. There, we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial. The search will continue. Not until the empirical resources are exhausted, need we pass on to the dreamy realms of speculation.

For two billion years, the world knew peace. Only with the invention of gender—specifically males, those tail-fanners, horn-lockers, chest-pounders—did Earth begin its slide toward self-extinction. Perhaps this explains Edwin Hubble’s discovery that all known galaxies are moving away from Earth, as if we are a whole planet of arsenic. Hoffstetler comforts himself that, on this morning, all such self-contempt is worth it. Until Mihalkov can authorize the extraction, Occam’s dogs need bones on which to chew.

Our modern picture of the universe dates back to only 1924, when the American astronomer Edwin Hubble demonstrated that ours was not the only galaxy. There were in fact many others, with vast tracts of empty space between them.

God knows we all have to at least try to justify our behavior so we don't feel too guilty about it later.

Yolo.

Our modern picture of the universe dates back to only 1924, when the American astronomer Edwin Hubble demonstrated that ours was not the only galaxy.

We all know so goddamn well what's best for other people that it seems unnecessary we get to know them before imposing our will on them.

The sphere to end all spheres—the largest and most perfect of them all—is the entire observable universe. In every direction we look, galaxies recede from us at speeds proportional to their distance. As we saw in the first few chapters, this is the famous signature of an expanding universe, discovered by Edwin Hubble in 1929. When you combine Einstein’s relativity and the velocity of light and the expanding universe and the spatial dilution of mass and energy as a consequence of that expansion, there is a distance in every direction from us where the recession velocity for a galaxy equals the speed of light. At this distance and beyond, light from all luminous objects loses all its energy before reaching us. The universe beyond this spherical “edge” is thus rendered invisible and, as far as we know, unknowable. There’s a variation of the ever-popular multiverse idea in which the multiple universes that comprise it are not separate universes entirely, but isolated, non-interacting pockets of space within one continuous fabric of space-time—like multiple ships at sea, far enough away from one another so that their circular horizons do not intersect. As far as any one ship is concerned (without further data), it’s the only ship on the ocean, yet they all share the same body of water.

PREFACE Cosmology is the study of the universe as a whole, including its birth and perhaps its ultimate fate. Not surprisingly, it has undergone many transformations in its slow, painful evolution, an evolution often overshadowed by religious dogma and superstition. The first revolution in cosmology was ushered in by the introduction of the telescope in the 1600s. With the aid of the telescope, Galileo Galilei, building on the work of the great astronomers Nicolaus Copernicus and Johannes Kepler, was able to open up the splendor of the heavens for the first time to serious scientific investigation. The advancement of this first stage of cosmology culminated in the work of Isaac Newton, who finally laid down the fundamental laws governing the motion of the celestial bodies. Instead of magic and mysticism, the laws of heavenly bodies were now seen to be subject to forces that were computable and reproducible. A second revolution in cosmology was initiated by the introduction of the great telescopes of the twentieth century, such as the one at Mount Wilson with its huge 100-inch reflecting mirror. In the 1920s, astronomer Edwin Hubble used this giant telescope to overturn centuries of dogma, which stated that the universe was static and eternal, by demonstrating that the galaxies in the heavens are moving away

That's why I try to keep KF hidden from my parents. My family is really paranoid about internet strangers. You know the type; every person on the internet is a pedophile and wants to meet up with you and molest you and dismember you slowly in their basement.

Then came a series of wondrous discoveries, beginning in 1924, by Edwin Hubble, a colorful and engaging astronomer working with the 100-inch reflector telescope at the Mount Wilson Observatory in the mountains above Pasadena, California. The first was that the blur known as the Andromeda nebula was actually another galaxy, about the size of our own, close to a million light years away (we now know it’s more than twice that far). Soon he was able to find at least two dozen even more distant galaxies (we now believe that there are more than 100 billion of them). Hubble then made an even more amazing discovery. By measuring the red shift of the stars’ spectra (which is the light wave counterpart to the Doppler effect for sound waves), he realized that the galaxies were moving away from us. There were at least two possible explanations for the fact that distant stars in all directions seemed to be flying away from us: (1) because we are the center of the universe, something that since the time of Copernicus only our teenage children believe; (2) because the entire metric of the universe was expanding, which meant that everything was stretching out in all directions so that all galaxies were getting farther away from one another. It became clear that the second explanation was the case when Hubble confirmed that, in general, the galaxies were moving away from us at a speed that was proportional to their distance from us. Those twice as far moved away twice as fast, and those three times as far moved away three times as fast.

In the mid-twentieth century, the subfield of cosmology—not to be confused with cosmetology—didn’t have much data. And where data are sparse, competing ideas abound that are clever and wishful. The existence of the CMB was predicted by the Russian-born American physicist George Gamow and colleagues during the 1940s. The foundation of these ideas came from the 1927 work of the Belgian physicist and priest Georges Lemaître, who is generally recognized as the “father” of big bang cosmology. But it was American physicists Ralph Alpher and Robert Herman who, in 1948, first estimated what the temperature of the cosmic background ought to be. They based their calculations on three pillars: 1) Einstein’s 1916 general theory of relativity; 2) Edwin Hubble’s 1929 discovery that the universe is expanding; and 3) atomic physics developed in laboratories before and during the Manhattan Project that built the atomic bombs of World War II. Herman and Alpher calculated and proposed a temperature of 5 degrees Kelvin for the universe. Well, that’s just plain wrong. The precisely measured temperature of these microwaves is 2.725 degrees, sometimes written as simply 2.7 degrees, and if you’re numerically lazy, nobody will fault you for rounding the temperature of the universe to 3 degrees. Let’s pause for a moment. Herman and Alpher used atomic physics freshly gleaned in a lab, and applied it to hypothesized conditions in the early universe. From this, they extrapolated billions of years forward, calculating what temperature the universe should be today. That their prediction even remotely approximated the right answer is a stunning triumph of human insight.

It had been a quiet few days for Hungry Paul since his Yahtzee conversation with Leonard, quiet days not being uncommon in his schedule. This had given him the opportunity to ponder the expansion and contraction of the universe as observed in localised form in the life of his best friend. Edwin Hubble, had he looked inside Leonard with his telescope, would have recorded that everything was just as the universe would ordain it. The thing is, for Hungry Paul the world was a complicated place, with people themselves being both the primary cause and chief victims of its complexity. He saw society as a sort of chemistry set, full of potentially explosive ingredients which, if handled correctly could be fascinating and educational, but which was otherwise best kept out of reach of those who did not know what they were doing. Though his life had been largely quiet and uneventful, his choices had turned out to be wise ones: he had already lived longer than Alexander the Great, and had fewer enemies, too. But he had now become awakened by the thought that, no matter how insignificant he was when compared to the night sky, he remained subject to the same elemental forces of expansion. The universe, it seemed, would eventually come knocking. And so it was that over a mid-morning scone he read a short article in the local freesheet with a sense of cosmic destiny.

Semayı biz kendi elimizle kurduk ve sürekli genişletmekteyiz." (Zâriyât sûresi, 51/47) Bu genişleme ister Einstein'ın anladığı mânâda, ister Edwin Hubble'in Güneş Sisteminin dahil olduğu galaksiden, nebülözlerin uzaklaşması şeklinde olsun fark etmez. Önemli olan Kur'ân'ın, ana temaya parmak basıp, tecrübî ilimlerin çok önünde zirveleri tutup onlara ışık neşretmesidir.

In several spiral nebulae, including the one called Andromeda, Edwin Hubble had identified a type of star, called Cepheid variables. His observations in 1922 and 1923 proved these star spirals were much too distant to be part of our Milky Way. They had to be entire galaxies outside our own. Many in the astronomy establishment—most notably Harlow Shapley—had opposed this idea. Hubble’s discovery was announced on New Year’s Day 1925. Eventually it changed the prevailing view of the universe. Hubble’s calculations put the distance of Andromeda at about 1 million light-years, several times the distance Shapley estimated for the outer limits of the Milky Way. Back at Harvard, Shapley read Hubble’s letter and remarked to a colleague, Here is the letter that has destroyed my universe.

Edwin Hubble looked through his telescope more than a decade later that scientists finally confirmed that the universe is expanding and that it’s expanding from a single point.

as Edwin Hubble taught us, is a hostile place.

Equipado com seus cinco sentidos, o homem explora o universo ao seu redor e dá à aventura o nome de ciência.

Edwin Hubble escaped the glare of ‘Orange county’ by retreating to a mountaintop observatory north of Pasadena, where he recorded the motions of the galaxies that led to his discovery of the expanding universe. But it wasn’t sodium that caused him difficulties. Potassium burns with a mauve flame which can sometimes be seen in a gunpowder explosion or when lighting a match. One night Hubble was excited to detect a potassium spectrum while he examined the galaxies through the world’s most powerful telescope. But it soon became apparent that the reading must be false. Eventually Hubble realized that the equipment had picked up the light from the potassium in the match that he had used to light his pipe.

Take solace in that, regardless of the fact that the love you had in your mind was lost, it was fairer than any, and you can take that with you forever.

We can create the world where we are with the ones we want to love so easily.

Edwin Hubble proved that the universe was expanding in 1929, confirming

Using the Mount Wilson Observatory, Harlow Shapley redefined our relationship to the cosmos, showing that the sun was not at the center of the Milky Way. Using it, Edwin Hubble created the whole field of cosmology, redefining again our place in the universe, our understanding of its vastness, and our ideas about its creation. Those discoveries did not bear any direct financial returns. They did not add to the national defense. But they did something far more important: they changed our lives and the way we think about ourselves. They are among the most profound discoveries of science, and they had no financial justification whatsoever. They were seeking truth and beauty amid chemistry and light.
