What else can I help you with?
The belief of early astronomers that the Earth was the center of the universe is called the?
geocentric theory
What did the early astronomers think the difference between the solar system and the universe?
They thought it was a explosion in the universe so they sent astronauts into space.
What did people of early civilations believe was the center of the universe?
i do believe its FAMILY
What did most ealy astronomers think made up the universe?
Early astronomers believed that the universe was made up of the Earth at the center, surrounded by concentric spheres holding the Moon, Sun, planets, and stars. This model of the universe, known as the geocentric model, was proposed by Ptolemy in the 2nd century.
How do astronomers find out about changes in galaxies over time?
Astronomers can watch galaxies that are far away. Since the light takes billions of years to reach us from the farthest known galaxies, they would be watching galaxies in the early Universe. It turns out, from such observations, that the Universe is changing.
Why did early astronomers believe the geocentric model was true?
Early astronomers believed in the geocentric model because it appeared to explain the motion of celestial bodies in the sky. The model was supported by the apparent daily motion of the sun and stars around the Earth. Additionally, there was a philosophical and religious belief at the time that Earth was the center of the universe.
How did humans discover the big bang?
The Big Bang theory was derived from observations made by astronomers in the early 20th century. By observing the redshift of distant galaxies, the cosmic microwave background radiation, and the abundance of light elements in the universe, scientists were able to piece together the idea of an expanding universe that originated from a hot, dense state known as the Big Bang.
Where did the cosmic microwave background (CMB) come from and what does it reveal about the early universe?
The cosmic microwave background (CMB) originated from the hot, dense state of the early universe about 13.8 billion years ago. It is the afterglow of the Big Bang and provides crucial information about the early universe, such as its temperature, composition, and density fluctuations. This radiation helps scientists understand the evolution and structure of the universe.
What fundamental forces pulled together hot dense areas of matter in the early Universe to begin the process of star formation?
gravity
Why do astronomers believe that globular clusters are made of old stars?
Astronomers believe the globular clusters are made of old stars because of the lack of heavy elements. The heavy element is very abundant in stars like our sun, so the theory is the globular cluster must be older and formed in a more primitive universe.
What is cosmic soup?
The term cosmic soup arises in cosmology to describe a period of time very shortly after the Big Bang, when the universe is thought to have consisted of a dense mixture of subatomic particles.
