2. What if gravity were like magnetism?

If an object with an electric charge moves in a magnetic field, it will experience acceleration at right angles to both its motion and the direction of the magnetic field. An electron moving through a magnetic field pointing up will turn left, for example, based on the right-hand rule (shut up!).

Granted, magnetic and electric fields are the relativistic versions of each other and gravity is just gravity. But what if gravity pushed things sideways? Then the most natural effect of gravity would be to go into orbit. Of course, centrifugal force would then cause those orbits to become progressively larger.

Still, an interesting idea.
