Radioactive dating animation
Some of them have orbits that cross the orbits of the planets and moons.
When they get close enough to a planet or moon, they will be pulled in by the large body's gravity and strike the surface at a speed of at least the escape velocity of the planet or moon, i.e., faster than a bullet.
Yet few people know how radiometric dating works or bother to ask what assumptions drive the conclusions. This figure wasn’t established by radiometric dating of the earth itself. Radiohalos shouldn’t exist, according to conventional wisdom!
There are still small chunks of rock orbiting the Sun left over from the formation of the solar system.The craters on all of the moons except Io, Mercury, and most of the ones on Mars are from impacts.The kinetic energy of the impacting meteorite or asteroid is converted into heat, sound, and mechanical energy---the projectile explodes on impact.One out of every 10,000 Potassium atoms is radioactive Potassium-40 (K-40).These each have 19 protons and 21 neutrons in their nucleus.
