Answer 1

Edwin Hubble
1889 - 1953


Edwin Powell Hubble is renowned for determining that there are other galaxies in the Universe beyond the Milky Way, and for observing that the universe is expanding at a constant rate.

Hubble was a tall, elegant, athletic, man who at age 30 had an undergraduate degree in astronomy and mathematics, a legal degree as a Rhodes scholar, followed by a PhD in astronomy. He was an attorney in Kentucky (joined its bar in 1913), and had served in WWI, rising to the rank of major. He was bored with law and decided to go back to his studies in astronomy.

In 1919 he began to work at Mt. Wilson Observatory in California, where he would work for the rest of his life. He was researching nebulae, fuzzy patches of light in the sky. In 1924, he announced the discovery of a Cepheid, or variable star, in the Andromeda Nebulae. Since the work of Henrietta Leavitt had made it possible to calculate the distance to Cepheids, he calculated that this Cepheid was much further away than anyone had thought and that therefore the nebulae was not a gaseous cloud inside our galaxy, like so many nebulae, but in fact, a galaxy of stars just like the Milky Way. Only much further away. Until now, people believed that the only thing existing ouside the Milky Way were the Magellanic Clouds. The Universe was much bigger than had been previously presumed.

Hubble wanted to classify the galaxies according to their content, distance, shape, and brightness patterns, and in his observations he made another momentous discovery: By observing redshifts in the light wavelengths emitted by the galaxies, he saw that galaxies were moving away from each other at a rate constant to the distance between them (Hubble's Law). The further away they were, the faster they receded. This led to the calculation of the point where the expansion began, and confirmation of the big bang theory. Hubble calculated it to be about 2 billion years ago, but more recent estimates have revised that to 20 billion years ago.

An active anti-fascist, Hubble wanted to joined the armed forces again during World War II, but was convinced he could contribute more as a scientist on the homefront. When the 200-inch telescope was completed on Mt. Palomar, Hubble was given the honor of first use. He died in 1953.

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

Edwin Hubble's mom.

Answer 3

who're you plagiarizing right here? somebody is heavily misinformed and garbling the best judgment and info. "Such an theory had no severe constituency until Edwin Hubble chanced on the redshift of galaxy gentle in the Nineteen Twenties," Theories are proposed to describe observations. Such an theory had no severe constituency earlier Hubble because of the fact it did no longer exist earlier Hubble. Georges Le Maitre proposed it in 1927 as a fashion of explaining Hubble's records. "inspite of the popular attractiveness of the huge bang concept as a working type for examining new findings," The "popular attractiveness" is by means of its fulfillment in predicting different issues that could desire to be talked approximately. it is how theories get popular, by explaining observations. by making effective predictions. "no longer a single important prediction of the thought has yet been shown," Flat out falsehood. the main mandatory and primary such prediction became the existence of the cosmic microwave heritage. it is thru no skill the only important prediction which has been shown. "and significant info has accrued against it." i pass to invite for a cite on that, because of the fact the info i'm responsive to is... 0. Misunderstandings, illogic and outright lies. Why am I no longer stunned? Edit: "however the furthest ones are blue shifted". Cite? thoroughly fake. "this skill that the furthest galaxies could have the utmost degree of purple shift". They do. "(and unquestionably be purple, as unfavorable to blue)". fake impact. "purple shift" refers to a metamorphosis in the wavelength of specific spectral strains, no longer the colour of something. The strains in question could be in the radio frequencies and not seen gentle in any respect. "neither astronomers nor cosmologists incredibly be responsive to how previous the universe is" you're previous, it is likewise familiar of creationists. they desire to cherry %. previous papers that have because been shown fake, or only misunderstand statements as you're doing. the main modern-day and ultimate estimate of the age of the universe is now 13.seventy 3 +- 0.12 billion years. The uncertainty is right down to a million%, and there is not any controversy approximately that. i don't be responsive to if the numbers you're quoting are even from physicists, yet while they're, they could be quite previous.

Answer 4

Hi. Hubble's greatest discovery was that, almost without exception, galaxies move away from each other. This demonstrated the expansion of the universe.

Answer 5

Look him up on the internet. (You do know how to do that, don't you?). You also might try Wikipedia for a succinct answer.

Oops! Somebody already did!!
