The Nature of Dark Energy

In this post, we look at the nature of dark energy. Is it fixed? Is it dynamical? Whatever it is, it is driving the accelerating expansion of our universe, and if we want to know its fate, we must come to know its nature.

Spin 1 Gauge Bosons.. How will we sleep?!

There are elementary particles that "carry" fundamental forces; they are the communicators of force. Gluons carry the nuclear strong force, photons carry the electromagnetic force, the W & Z bosons carry the weak force... awww. But what particle links our observable universe with the mysterious dark sector? Could a spin-1 gauge boson be the communicator for dark matter?
