How Did Hans Lippershey Use The Telescope

In the past decades, scientist always wonders what is beyond earth, or as what they call it, the universe. As a result, had impacted parts of earth that’s been burned down by meteors. Hundreds innocents life were dead because of it. Therefore, in 1608, as the glassmaking and lens grinding skills was improved, Hans Lippershey tried to accuse on a device using three-times magnification. He uses a concave eyepiece coordinate with a convex objective lens. Lots of stories say that he got the idea from another eyeglass maker, Zacharias Jensen. They both lived near by and both worked on making optical instrument. However Lippershey are known as the creator of the telescope, therefore Jensen are know within inventing a compound microscope.
Couple weeks later, Jacob Metius, a Dutchman, practiced for a patent for a telescope. Yet the government of Netherlands rejected
Galileo Galilei discovers that Jupiter had its own rings, and sun had sunspots, using the telescope.

As a result, many countries at that time didn’t have a telescope due to the economical issue. Thus, most countries wouldn’t be aware of a meteor coming, and didn’t have the time to evaluate the certain area that’s going to be hit. To that end, how did the countries survived and became a world with much improved technologies to help determine meteors coming in cities?
Therefore, how did the society survived and became a world, with modern technologies to help determine diseases in humans?
Scientist needed leading imaging technologies that permits scientist to view a much more clearer image yet still profitable for most countries. Therefore, only optics and lights that could give a high quality image since light is the fastest source. When light is being reflected using mirrors, it would travel faster through the universe. Isaac Newton reasoned that I would be better to make telescope out of mirrors rather than
