Galileo Galilei changed the world today because he invented many space telescopes that still come in handy today, he also was the one of the only people that experimented his own theories. I LOVE RYAN ANDREW SWIFT
yes he was a composer but after his death he was no longer a composer
Galileo is an Italian astrominor from the rennaissance. He believed in the theory of heliocentricity.
Galileo used more advanced technology to find stronger observational evidence than Copernicus was ever able to provide.
Galileo was an Italian astronomer, physicist, and engineer. He made significant contributions to the fields of physics, astronomy, and the scientific method.
Galileo used his telescope to look into space where he noticed that Nicalous Copernicus was correct in saying that the Earth revolves around the sun. Which Galileo was arrested for believing.
They believed that the Earth was the centre of the universe even after Galileo presented his idea. It was later proven that the sun was the centre of the universe.
Galileo's quarrel with the church over the heliocentric theory opened a gap that left the religious authorities suspicious of scientists, do the detriment of both.
Both Carl Sagan and Galileo were influential scientists in their respective times. Galileo made significant contributions to the fields of astronomy and physics, while Carl Sagan was a prominent astrophysicist known for his work in popularizing science. It is difficult to compare their impact as their contributions were made in different contexts and time periods.
No, Galileo did not invent the pendulum. The pendulum was actually invented by Italian mathematician and scientist, Galileo's compatriot, named Domenico Mancini in 1582. Galileo did however conduct important experiments on the pendulum and made significant contributions to its understanding and application.
