Our understanding of the universe has changed a lot over time!
Ptolemy
He improved on Aristotle's theory which was that the earth was the center of the universe also known as geocentric.
Nicolaus Copernicus
Copernicus had a theory that the sun was the center of our solar system. This is also known as heliocentric.
Tycho Brahe

Brahe hired Kepler, another astronomer to work with him.
How has our understanding of the universe changed over time?
Aristotle
Johannes Kepler
Galileo
Isaac Newton
Edmund Halley
Edwin Hubble
By Isamilla & Nelleke
The Hubble space telescope was named after Edwin Hubble.
He had three laws of motion.
He hypothosized that the nebulae were their own galaxies.
<span>He imagined the earth at the </span>
center of the universe with the sun, the moon, the stars and the planets orbiting it in perfect circles.
Newton put Kepler and Galileo's ideas together and discovered that the reason that things fall on the ground is the same reason that planets orbit around the sun.
He made a telescope that could magnify
up to 30 times.
<span>He discovered that Copernicus' theory </span>
was true. "We're not the center of the universe."
He found out that the planets orbit the
sun in ellipses (oval shapes).
He explained how the tides were made by the moon.
He figured out that the speed of the planets depend on the sun.
Halley discovered a comet. It was discovered in 1705. It will come around again in 2061
The comet Halley comes every 75 - 76 years

Conta is a greek word and i need to know what it means it english. someone tell me what it means in english, you very much
Answer:
Option A, GV law
Explanation: The laws of gravity (actually called "Newton's Law of Universal Gravitation") are laws in the field of classical mechanics that tell us the behavior of gravity.
now the simplifications are:
a) GV Law
This is fine because with this method you will always remember that these are laws.
b) L of G
This could mean different things, it is not advisable to use this type of abbreviations, since you can read it and not remember what L or G means.
c) VGlity
I really don't understand what this means, this is not a good option.
d) Newt gravity.
This option is also good because you can remember Newton's name, but it is a bit longer than the first option.
So, the option that has more information and is also shorter is the first option of the GV law, so that would be the correct option
