Why Earth doesn’t simply crashes into the Sun [video]

Because we live in a 3D world. And because the astrophysics is so amazing. Because the gravitational pull of the Sun doesn’t mereley pull Earth nearer to Sun’s surface it also accelerates our planet on the trajectory.

This way you will always have a slightly different path that our planet uses to orbit the Sun. And this is why solar systems can exists. Gravitation and acceleration make a good couple. Eventually Earth will crash on Suns surface is the end of the Universe doesn’t shows up in more than 5-10 billion years form now. But that’s another history. By then the Reapers would have come ang go countless times.
