Is the worlds largest reflecting telescope one meter in diameter?
No, as of this time and to my best knowledge the largest single piece reflecting telescope is the Japanese reflector in Hawaii called the Subaru.
Newton did not originally invent the telescope. They were invented in the Netherlands in 1608 and improved on by Galileo in 1609. Those were what are known as "refracting" telescopes (a series of lenses that the observer looks through). But Newton did invent the reflecting telescope, which uses a parabolic mirror to gather light, rather than a lens. The worlds largest optical telescopes are all reflectors.
