Neutron stars take center stage again as scientists are probing their mysteries when they saw Einstein's predicted warping of spacetime around three neutron stars. Because of this discovery, scientists are now on a search to find exotic atomic particles that they can't create in a lab but could study by observing these warping effects.

Now before you think that this is a quest to build a phone booth that can travel in time to meet a way cooler version of Keanu Reeves as Ted (let me get to the point before I digress), we're not talking spacetime in terms of past and future. We're talking spacetime in terms of gravitational effects.

Basically, objects inhabit a place in spacetime that forms a kind of warping. The warping is like a bowl, and any object placed near the tip of the bowl automatically drops to the bottom center. Gravity is the same thing: objects attract each other because of the "bowls" they create in space time. The larger and denser the object, the larger the warped bowl effect, the greater the gravitational force.

Brief science lesson over. The spacetime warp effects were seen when scientists observed a disc of hot gas around the neutron stars. Neutron stars are very dense: a few cupfuls would be heavier than Mount Everest. Because of this, gravitational forces of the star pulled on the light from the disc and turned it red. This is called gravitational redshift, the effect stated by Einstein's theory of relativity.

Because of this discovery scientists have been able to develop a new technique of studying the neutron stars, allowing for a more accurate way of observing the effects of exotic particles.
