These questions used to be just the subjects of philosophy or metaphysics. Now that we can try with scientific methods, we hope to continue the tradition.

One idea that I toyed around with is that dark energy is a complicated network of rubber sheets. If you stretch them, you have to provide force and because of it, the sheet gains energy. The universe expansion is much like stretching this network of sheets, which increases energy.

We hope that one of these new particles that may get created will be this dark energy particle.
