[Star wars] I get two lightsabers and press one against the other. I press down with an INCREDIBLE amount of force. Will this cause the blades to go through each other?

There isn't a whole lot that the galaxy at large knows about lightsabers.  The secrets of their construction were closely-guarded secrets by the Jedi, and trying to find any information on their forging from other, darker sources is even more futile.  Are they simply glorified blaster bolts frozen in place?  Are they arcs of white-hot plasma contained in a magnetic field so tightly that it's a single blade for all intents and purposes?  None, save those that use them, know for sure.

In the first scenario (frozen blaster shots), it's unlikely.  Regardless of their makeup or construction, these are still beams of pure energy.  They'll lock, they'll repel one another, and will likely cut through your hilt before they do each other.  And on the other hand (arcs of plasma in a mag-field), pressing down with an INCREDIBLE amount of force will cause at least one magnetic field to rupture, causing white-hot energy to erupt all over your face.

Good luck.
