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

History

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.

Que diferencias hay entre las corrientes que explican el origen de la humanidad creacionistas y cientificas?
Gnesinka [82]

La respuesta correcta para esta pregunta abierta es la siguiente.

A pesar de que no se anexan opciones o incisos para responder a la pregunta, podemos comentar lo siguiente.

¿Qué diferencias hay entre las corrientes que explican el origen de la humanidad Creacionista y Científicas?

Cuando hablamos de la perspectiva Creacionista, estamos hablando de un postulado religioso que indica que la creación del hombre proviene de la voluntad de Dios. Se basa en los textos de las llamadas sagradas escrituras o Biblia Cristiana. Esta óptica de la creación del hombre se plasma en el primer libro del Antiguo Testamento, llamado El Génesis.

La perspectiva Científica indica que el hombre es producto de una evolución natural de las especies. Una delas teorías científicas más reconocidas en este sentido es la Teoría de la Evolución de las Especies, del científico Charles Darwin.

Para la ciencia, el hombre es el producto de la evolución de miles y miles de años, hasta llegar a ser una creatura H*mo Erectus para finalmente convertirse en un H*mo Sapiens.

schepotkina [342]

Answer:

c.the period of time known as the Middle Ages.

Explanation:

The crusades were a series of military campaigns promoted by the Pope and carried out by a large part of Christian Latin Europe, mainly by the France of the Capetians and the Holy Roman Empire. The Crusades, with the initial specific objective of restoring Roman apostolic control over the Holy Land, were fought over a period of almost two hundred years, between 1096 and 1291. Later, other campaigns in Spain and Eastern Europe, some of which they did not see its end until the fifteenth century, received the same rating. The crusades were held mainly against the Muslims, but also against the pagan Slavs, Jews, Greek and Russian Orthodox Christians, Mongols, Cathars, Hussites, Waldenses, Prussians (or Prussians), Lithuanians (in general against the Baltic peoples) and against enemies. politicians of the popes. The Crusaders took vows and were granted indulgence for the sins of the past.

What is increased to increase revenue that people generally don't like
julia-pushkina [17]

Answer: Prices

Explanation:

There are several ways to raise revenue from sales and one of them is to increase prices. With a higher price, more money will be paid per goods and if the cost is still the same, the increase in price becomes extra profit.

Increased prices however reduce the amount of money that consumers have after purchases so they do not like it when prices are increased. It reduces the amount of goods they can buy especially if their wages do not go up as well because they will have to spend more per good.
