Amateur Rocket Shows the Curvature of the Planet from 56 Miles Altitude

A team of amateur rocketeers show us what they did on their first test flight without any help from NASA. They built a two-stage amateur rocket which flew to 293,488 ft (55.6 mi/89.5 km). This rocket is called MESOS (short for mesosphere) because it is designed to fly there. The mesosphere is the third layer of Earth’s atmosphere situated between 31 and 53 miles (50-85 km) above the surface. The amazing part about this rocket is it reached this altitude on less than 41,000 N-s of total impulse (full O-class high power rocket motor)! Capable of carrying the equivalent of a 16 oz can of beer/energy drink as a payload, this rocket flew two GoPro Hero 9s cameras with modified rectilinear lenses. Both stages are recovered via parachutes and are reusable. This video covers the development and the launch of this record breaking rocket. I hope you enjoy it!

6-Day Creation of the Universe

6-daysThe big bang theory describes the origin of the Universe starting some 13.8 billion years ago with a ultra-hot plasma cooling to form hydrogen and helium gas in an expanding universe. From this, a billion years later, stars and then galaxies allegedly started to form. Some of the stars exploded building the heavier elements and dust and then about 5 billion years ago our sun allegedly condensed from a solar nebula of the gas and dust from recycled stars. Then about 4.6 billion years ago planet Earth and the rest of the planets in the solar system formed from the remnants of that cloud. Eventually the Earth cooled, oceans formed, life started by some unknown mechanism, crawled out of the ocean onto the land, and over the past 3.8 billion years life evolved from single-celled organisms to the complex life today. Man allegedly evolved from some ape-like ancestors over the past 2 million years. But what does the straight-forward account of the Creation in Genesis chapter 1 describe?
