Sometimes in our mind, some amazing idea come and go but it is not possible to Practically do them, reason can be anything related to our time, money or resources. Similarly in science, there are many ideas but for now, they are impossible to invent.
The fact that they are logically feasible doesn’t mean they can be built in reality, so what theoretical devices are the most impossible to invent?
Although there are many inventions that people thought impossible to invent but some mastermind invented them!!!
It is a form of a vehicle or of a portal connecting distant points in time. Time travel is a recognized concept in fiction or sci-fi based movies or tv series, but in reality, traveling to an unreasonable point in time has a very confined support. One-way time travel into the future via time dilation is a well-understood phenomenon but traveling a large amount of time is not fit with current technology.
The concept was popularized by H. G. Wells’ 1895 novel The Time Machine, which moved the concept of time travel into the public imagination, and it remains a popular subject in science fiction from now on.
The laws of physics declare that it is theoretically possible to travel back and forth through the fabric of space-time. In order for something or someone to travel through time, he, she, or it would have to travel at a speed equal to the speed of light and unfortunately, no form of matter can ever achieve it till now. So the dreams of using a time machine would have to remain as it is… a dream.
2. X-Ray Glasses(that can only see through clothes)
X–Ray Specs are an American novelty item, Using these glasses people are allowed to see through or into solid objects. In reality, the glasses merely create an optical confusion; no X–rays are involved. Viewing things within the range of X-Ray beams highly require great amounts of energy and not to mention an assemblage of bulky equipment. Currently, it is not possible to construct such a small component so it would fit into the small frame of standard spectacles. Even if we can miniaturize them, It is not scientifically possible to clear and direct visualize through or project of any shielded object.
Teleportation has been a total theoretical concept but it’s very interesting for at least the people who want to travel places fast without any limit like me!!
Teleportation is the theoretical transfer of matter or energy from one point to another without crossing the physical space between them. It is a common subject in science fiction literature, film, video games, and television. Some scientists believe it is not possible to teleport macroscopic objects such as human beings, but scientist may achieve teleportation in the microscopic world.
Google X has also denied taking this project.
4. Perpetual Motion Machine
Perpetual motion is the motion of bodies that continues indefinitely. A perpetual motion machine- this can be a hypothetical machine that can do work continually without an energy source.
This kind of machine is impossible, as it would violate the first or second law of thermodynamics. Thus, machines that extract energy from finite sources will not operate indefinitely, because they are driven by the energy stored in the source, which will eventually be drained. A common example is devices powered by ocean currents, whose energy is ultimately derived from the Sun, which itself will eventually burn out.
