How long has the universe existed going by the Steady State Theory?
The steady-state theory is obsolete - it is now known that the Universe does change over time (the Steady-State Theory states that it doesn't). According to the Steady-State Theory, the Universe has no beginning and no end.
What three incorrect idea held back the development of modern astronomy from the time of modern astronomy from the time of Aristotle until 16th century?
Scientific theories are based on observations and deductions, and the Ptolemaic theory of the solar system fitted the observations of the planets' positions quite well, so it was not wrong, it was OK until better measurement methods showed that it needed improving. The Ptolemaic model of a planet's orbit, also used by Copernicus, had the planet moving round a small circle called an epicycle once, while the centre of the epicycle moved round a circular path, also once, in the opposite direction. This is not a bad model for an elliptical orbit with low eccentricity, which looks like a circle with an offset centre, which is what the Ptolemaic model describes. But Kepler had Tycho's recent observations when he discovered the new laws of planetary motion in which the planets move in ellipses. Tycho's measurements were just accurate enough to allow Kepler to discover the difference. So the old ideas had to wait until the science of measurements were good enough to point the way to elliptical orbits, and that took a long time.
What theory best explains the moons origin?
Giant Impact Theory which tells that a very big asteroid named 'theia' hit earth in a long time ago resulting a large debris ring which later formed moon....
According to the Big Bang Theory how have the density and temperature of the universe changed over time?
The "big bang" theory is still relatively new. British astronomer Sir Fred Hoyle came up with the term "big bang" as a derogatory term in the 1950's, because Hoyle was a life-long believer in the "steady state" theory of the universe.
How long is a day in the Milky Way galexey?
A "day" is basically the time Earth rotates around its axis. Sometimes people talk about a "day" on other planets, which can be anywhere between a few hours and several months. There is no commonly accepted equivalent for the Milky Way.
Why WAS THE PTOLEMAIC THEORY ACCEPTED FOR LONG TIME?
Because the theory had predicted the motions of the planets better than any known method at that time.
How did galileos findings with the telescope disprove the Ptolemaic theory?
A model is never technically disproven or proven. The ptolemaic model is no longer accepted because it does not adequately explain observations. The heliocentric model was accepted gradually because it was a better explanation for observed phenomena. However, people continued to believe the ptolemaic model long after it was irrational to do so.
Was Copernicus theory widely accepted?
The heliocentric theory became widely accepted when it was found that the Sun is by a long way the most massive object in the solar system. That happened in the 18th century.
Was Copernicus's theory widely accepted?

What theory of albert Einstein was not acceepted for a long time?
brownian motion was accepted early on, but his special and general theories of relativity, and his theory regarding quanta took longer to be accepted by all.
What old belief about the universe did the new discoveries destroy?
they went against the long accepted geocentric theory.
Whose theory of the universe was held as law for a thousand years even though it was wrong?
The Ptolemaic theory of the planets lasted 1400 years, and it lasted so long because it was not very wrong. But when Galileo discovered all the phases of Venus, the theory's days were numbered. This did not happen until Galileo came along with his telescope to study the night sky.

Why was Copernicus' work controversial?
Because people liked to believe that the Earth was at the centre of the universe and the Ptolemaic model of the universe had been seen as accurate for so long that any other idea was disapproved. It's like Darwin's theory of evolution, at the time nobody liked to believe it, it was only years later that we realised it was an extremely likely theory.
How did Copernicus change peoples' view of the solar system?
Copernicus published a new theory of the planets in 1543 which had the Sun at the centre. Other than that the theory was similar to the old Ptolemaic theory in that it used circles and epicycles to model the paths taken by the planets.66 years later, Kepler's theory was published. It had the Sun at the center, like the Copernican theory, but in all other respects it was novel because it used the new idea of elliptical orbits for the planets. Eventually Kepler's model became generally accepted and the older models were discarded.But Copernicus was the first to publish a serious alternative theory to the one by Ptolemy from 1400 years earlier. In that sense he initiated the Renaissance as far as the study of Astronomy was concerned.Copernicus was the first astronomer to reconsider the theory that explains how the planets move among the fixed stars. The Ptolemaic theory with the Earth at the centre had been around long enough (1400 years) for it to be incorporated in the scriptures and therefore difficult to change.Copernicus's alternative model published in 1543 had the Sun at the centre and all the planets including the Earth travelling round in orbits that were made up from circles.Copernicus's model has the planets, particularly Venus and Mars, moving in paths that are geometrically simpler. Other than that, there was no way of knowing which model was a better representation of reality.Galielo took up Copernicus's model and promoted it aggressively to the extent of starting a major dispute with the Catholic authorities.However both theories were eventually discarded in favour of Johannes Kepler's theory of 1609 when later discoveries in gravity and dynamics showed that the planets follow Kepler's three laws of planetary motion under the force of the Sun's gravity.The idea of having the Sun in the center is now generally accepted as right, and Copernicus gets the credit for starting the train of thought that arrived at the correct solution even though the details of his theory were not accepted.
Why was Ptolemy's idea of the universe accepted so well by the church?
It was ptolemy that gave the assumption on the use of devices in the system of the universe
Use the word theory in a sentence?
Keep in mind that the word "theory" has a different meaning to scientists from how most people use it in casual conversation. In science, a theory is a hypothesis or group of hypotheses that have been supported with repeated testing. A theory is valid as long as there is no evidence to dispute it. Therefore, theories can be disproven. Basically, if evidence accumulates to support a hypothesis, then the hypothesis can become accepted as a good explanation of a phenomenon. One definition of a theory is to say it's an accepted hypothesis. hi look i just wanna say that we need a sentence not a definition oh yeah and i rly didnt understand that thing you wrote no offense
