How did scientists originally view the idea of an expanding universe?

History

Fiesta28 [93]3 years ago
5 0
By using and testing Einstein's theory of General Relativity, scientists have observed galaxies moving away from Earth. A few years after Albert Einstein had developed his famous (and by now very well tested!) theory of General Relativity (GR) in 1915 he applied it to the entire universe and found something remarkable. The theory predicts that the whole universe is either expanding or contracting. There really isn't any other alternative. To have the universe staying static is like a pencil balanced on its point... possible, but very, very unlikely and not liable to last for very long. Since the time of Hubble we have observed millions of galaxies with better equipment and verified his results. With the exception of a small handful of galaxies close to us, every galaxy is moving away from us. And in fact, the farther away a galaxy is the faster it is moving away from us. This fits in very well with Einstein's predictions. The galaxies seem to be receding from us because the entire universe is getting larger. The space in between the galaxies is stretching! And the farther away a galaxy is the more space there is to stretch so the faster the galaxy appears to move away from us.

4. Was the price offered for Alcatraz Island fair? Why or why not?
AURORKA [14]

The correct answer to this open question is the following.

Although there are no options attached or further context or references, we can comment on the following.

The price offered for Alcatraz Island ($9.40) was fair because it was practically the amount the government originally paid the Native Indians or 47 cents per acre.

After closing the prison in 1963, the government's idea was to sell it to private investors but that is when Native American Indian protests started. Native Indians argued the existence of a treaty that said that if the government abandoned federal land, it had to be returned to the Indians.

These Native American Indians influenced the United States government and raised the spirit of their community by occupying Alcatraz.

Which of the following statements best characterizes the House Un-American Activities Committee in the 1950s? The House Un-Ameri
aalyn [17]

The correct answer is: "The House Un-American Activities Committee wrongly accused many people."

The House Un-American Activities Committee (HUAC) was founded in 1938 as an investigative committee dependent on the House of Representatives. It intended to detect and combat subversive behaviours observed in private citizens or public employees, or possible relationships of US population with either Communism or Fascism. It was specially active during the Cold War era. It worked also to uncover foreign espionage, mainly from the URSS during the Cold War, but it cannot be said that it manage to end espionage activities. It was dismantled in 1975 and its functions are now in charge of the House Judiciary Committee.

The HUAC many times used its power to call citizens to testify before Congress, without a strong evidence backup, in a very intimidating atmosphere, giving rise to dramatic and questionable testimonies. It was an instrument which created fear, distrust and was used for political repression.
