http://www.telegraph.co.uk/science/science-news/8857154/Worlds-most-powerful-laser-to-tear-apart-the-vacuum-of-space.htmlUnder the theory that even a vacuum is populated with "ghost particles" that hop trans-dimensionally, scientists want to make a laser that is more powerful at its focal point than the core of the Sun. And they want to smite these particles and cause them to disassociate into smaller particles in the hopes that they can then detect them.
Newton's Laws concern me in regards to this.
-For every action, there is an equal and opposing reaction.
If these particles "hop" transdimensionally, then there is already an energy source fascilitating this transdimensional hop. And that energy source is depleted and extinguished when the particle enters our dimension and then immediately leaves.
Destroying the particle before it leaves... robs the reaction of the sum of energy and mass that result in a 0 energy/mass final result in our Universe. And leaves a door open... somewhere.
Makes me think of uncontrolled/spontaneously opened interdimensional portals. And head crabs.
More mundanely, I wonder with my non-physics-trained noggin, if this transdimensional vacuum particle portal they seek isn't really the equivalent of a black hole's digestive tract, and the little particles are kind of like gas. Halting the reaction that is supposedly happening might overpressurize a black hole somewhere and cause it to go nova.
