From the page: Explanation: Put a satellite in a circular orbit about 42,000 kilometers from the center of the Earth (36,000 kilometers or so above the surface) and it will orbit once in 24 hours. Because that matches Earth’s rotation period, it is known as a geosynchronous orbit. If that orbit is also in the plane of the equator, the satellite will hang in the sky over a fixed location in a geostationary orbit. As predicted in the 1940s by futurist Arthur C. Clark, geostationary orbits are in common use for communication and weather satellites, a scenario now well-known to astroimagers. Deep images of the night sky made with telescopes that follow the stars can also pick up geostationary satellites glinting in sunlight still shining far above the Earth’s surface. Because they all move with the Earth’s rotation against the background of stars, the satellites leave trails that seem to follow a highway across the celestial landscape. For example, in this wide view of the nearly…
Unkept and ratty imo
i love his smile no matter how chipped his tooth is lml
I love your videos ! Please continue to post them !
Thanks so much for your comment!! that was really nice!!! if you ever need anything please dont hesitate to ask ok??
well it could have been the pilot because i don't know much about flying but i do know you need someone from the FAA to inspect the aircraft to legally fly it, so either it was the pilot or they were flying illegally because they didn't have anybody from the FAA to look at it first
watched this at school
One of the theories on the state of the universe encorporates five dimensions. The universe as we know it floats in this fifth dimension in a structure called a bane. The universe though is not alone there are other universes also in the fifth dimension, and it is the reaction of two universes meeting and interacting that scientists believe caused the big bang (ie they compress each other into a tiny space before moving away again and the two grow rapidly).
Because the universe is believed to exist in this fifth dimension there is no finite edge just an emptiness that is the fifth dimension containing other universes.

the whole beat and tune of this song is pretty upbeat compared to what its really about and the lyrics LOL
OMG so your not like in one of those buildings where your neighbors have telescopes
