SCIENCE FICTION TECHNOLOGY EXPLAINED | Universe documentary | Real SCI-FI fiction

One promising human technology currently being researched might explain such phenomenon. There is a technology on the horizon which might change things visually. And that is a kind of light-bending technology. As a class, they're called metamaterials. If you want to think about popular movies, think the invisibility cloak in the Harry Potter movies. Metamaterials use combinations of polymer substrates, gold, and copper to forcibly bend electromagnetic waves around an object. The light is guided around the object rather than being reflected or refracted. But advanced materials, stealth capability, and mind-bending maneuverability would all come to nothing if our visitors were unable to get to Earth in the first place. I'd say that the chances of another civilization making it here to visit us are pretty miniscule. But if they did make it, it would mean that they had solved a whole bunch of problems, including material-science problems that we don't have answers to. So they'd have technology far beyond ours, perhaps even beyond what we've dreamt of at this point. The highest energy source known in the universe and potentially the key to interstellar travel. The best way of making antimatter here on Earth is to employ probably the most famous equation that Einstein taught tells us that for a certain amount of matter, we can get energy. It's a great idea because it's incredibly efficient. You essentially take all of the mass in those particles and convert it into energy. But how can antimatter exist in the universe if it must be artificially manufactured?
