Earth seems finely tuned so we can exist. It’s the perfect distance from the sun for mild temperatures and liquid water‚ it has a protective giant‚ Jupiter‚ nearby to keep rogue asteroids from hitting us - all key requirements for intelligent life to evolve. But the Earth is not fine-tuned. The galaxy is teeming with at least 100 billion planets. By chance alone‚ there will be at least one fit for intelligent life.

Presumably 4.6 billion years ago‚ the Earth formed under extreme heat and pressure making the atmosphere extremely hot. During this time‚ known as the Hadean period‚ our young planet was being constantly bombarded by asteroids‚ comets‚ and meteors‚ which contributed to the immense heat in the atmosphere. Millions of years later‚ the planet was pulled into the orbit of the Sun due to its gravitational pull and started to cool down. As the Earth cooled down‚ its atmosphere

extinction of certain animal species and plants that is facing the Earth today has been compared to‚ although some scientists suspect worse than‚ the extinction of the dinosaurs. The annihilation of the dinosaurs was caused by the collision of a large asteroid with the Earth. This current mass extinction‚ however‚ is different than any of the five mass extinctions that have been seen by the earth because this extinction is manmade‚ not natural.

Impact craters are geologic structures formed when a large meteorite‚ asteroid or comet smashes in to a planet or a satellite. Meteorites are small rocks in space that hit the earth’s atmosphere at a high velocity. Throughout their history they have heavily bombarded all the inner bodies in our solar system. In this experiment we will use marbles as our meteorites‚ these will be free falling objects that will be used to copy an asteroid impact.
