Question: Is there such thing as a wormhole???

Yes, however, before going there, let’s briefly discuss black holes.

A black hole is believed to be the end result of a suitably massive star, but nobody has observed a black hole directly. If we find a light-emitting star orbiting a point in space, chances are it is a black hole. This is the PHYSICAL interpretation. From a MATHEMATICAL point of view, black holes also exist as solutions to Einsteins equations of General Relativity.

Now, Rosen-Einstein bridges are also solutions to Einsteins equations and are typically called wormholes. They may allow one to travel from point in the Universe to another much faster than the speed of light, since they constitute shortcuts.

So, are they real or not? Are they PHYSICAL or purely MATHEMATICAL? This is the real beauty of mathematics; mathematical physicists can often make predictions about Nature long before any observation.

Charles Darwin on the sixth sense of mathematics:
“…… I attempted mathematics, and even went during summer of 1828 with a private tutor……but I got on very slowly. The work was repugnant to me, chiefly from my not being able to see any meaning in early steps in algebra. This impatience was very foolish, and in after years I have deeply regretted that I did not proceed far enough at least to understand something of great leading principles of mathematics, for men thus endowed seem to have an extra sense……….”
