The development of jetpacks appears to be impossible until we discover a new, super-powerful, and most importantly, affordable source of energy. Possibly, it would be possible to try – and sometimes reduce – nuclear reactors? However, few people would dare to carry a miniature nuclear power station on their backs.
Another factor that calls the development of jetpacks into question is safety. For example, if your car breaks down unexpectedly, you are not in imminent danger. If you use a jetpack, you will die from falling from a great height.
Take a look at the numbers to see why scientists are still unable to teleport people. Quantum teleportation transports information from one location to another. The human body is composed of 50 trillion units (cells), each of which is far more complex than a single photon. Disassembling a person into parts and then reassembling it in another location with absolute precision, without missing a single molecule – this is now beyond even theoretical comprehension.
3. Mind reading
The most that so-called “mind reading machines” can do is recognize images and emotions. Modern technologies are still a long way from being able to recognize specific thoughts.
Consider that the human brain contains over 80 billion neurons that are linked by 40,000 connections. It is extremely difficult to simulate such a scene, and our thoughts are not yet static. They are found all over the brain. It would take a large number of experimental subjects and countless hours to create such a device.
4. Invisibility cloak
We were all fans of the Harry Potter series. Remember how, in the Philosopher’s Stone, he wrapped himself in the invisibility cloak? Recent research has revealed that there is a fundamental limit to how well cloaking devices can work without violating physical laws. There are no materials in nature that can reflect waves of varying lengths as well as light and radio waves. Even the best invisibility cloaks, in theory, will only be able to make objects partially invisible.
5. Pills instead of food
The average person requires about 2,000 calories per day. If that many calories are ever concentrated in a pill, humans will have to take them in batches. To be more specific, 250 grams of tablets per day. on the list of favorites, A meal like this will never be as appealing as a flavored slice of pizza.
