Time Travel Is Possible 0 (0)

Since relativity is our most profound theory of time, we would like to argue that time travel is forbidden by relativity. Einstein had thought that his description of space-time would forbid time travel. But this is simply wrong. Not only is time travel not ruled out but we can actually design time machines.

Why Do We Keep Looking For Dark Matter? 0 (0)

About 20% of the matter in galaxies is visible. The other 80%, referred to as “dark matter”, remains mysterious and unseen. In fact, it may not exist at all. “Dark matter” is just a hypothesis. But watch the video to learn why we still keep looking for it.
