Technology has grown exponentially over the past few centuries, making things possible that were once absolutely considered completely impossible. A well known misquote said that everything that can be invented has been invented. That was uttered more than a hundred years ago, and if it had been true, we wouldn’t be reading this article sitting hundreds or thousands of miles apart in front of a lit up glass screen. Science redefined the term impossible; while the laws of physics themselves considered incomplete, now impossibilism has become unscientific and here we anticipate for these achievements that would revolutionize everything!
A whole-body transplant or brain transplant is a hypothetical operation that would move the brain of one being into the body of another. It is a procedure distinct from head transplant, which involves transferring the entire head to a new body, as opposed to the brain only. Theoretically, a person with advanced organ failure could be given a new and functional body while keeping their own personality and memories. Although many scientists have challenged the feasibility of this process, few would say that it was not possible given current research into organ transplant and human cloning. Some bioethicists argue that there are difficult moral problems involved in either harvesting a brain-dead body, especially one deliberately created using human cloning, or otherwise acquiring a body (say, of a criminal due to be executed for a crime, or an individual who is not dead but is soon to die of a brain-based illness). Though not feasible at current levels of technology and scientific understanding, this and similar concepts have been explored in various forms of fiction. One of the most significant barriers to the procedure is the inability of nerve tissue to heal properly; scarred nerve tissue does not transmit signals well (this is why a spinal cord injury is so devastating). However, recent research at the Wistar Institute of the University of Pennsylvania involving tissue-regenerating mice (known as MRL mice) may provide pointers for further research as to how to regenerate nerves without scarring. An arguably more reasonable scenario is a partial brain transplant involving only enough tissue to provide key memories and a sense of continuity of identity. A fairly large but indeterminate amount of the brain is devoted to processing and controlling sensory, motor, and autonomic functions such as vision, olfaction, movement, appetite, etc.; transplanting these portions is likely to be difficult and, if the goal is to transfer memories and/or identity, unnecessary.
9. Travel to the Earth’;s Center
Travel to the Earth’;s center, though not considered possible with today’;s technology, is a popular theme of science fiction. Some subterranean fiction involves travel to the Earth’;s center, either finding a Hollow Earth or the Earth’;s molten core. Though no scientists have seriously proposed travel to the Earth’;s center, planetary scientist David J. Stevenson suggested sending a probe to the core as a thought experiment. So far, the deepest humans have drilled is just over 12 kilometers (7.66 miles). In the 19th century, it was generally thought that man would reach the center of the Earth long before he reached the Moon. This shows just how unpredictable technology can be. A journey to the center of the Earth is actually much more difficult than it sounds. The pressure at the center of the Earth is enormous because, quite literally, the entire weight of the world is on top of you. A “;Hollow Earth”; belief posits that the planet Earth has a hollow interior and probably a habitable inner surface. At one time, adventure literature made this idea popular. The scientific community dismisses it as pseudoscience – but it remains a popular feature of many fantasy and science fiction stories, and is an explanation used for conspiracy theories. Thus we have yet to see what lies beneath us and we so want to see.
8. DNA Computing
DNA computing is a form of computing which uses DNA, biochemistry and molecular biology, instead of the traditional silicon-based computer technologies. DNA computing, or, more generally, biomolecular computing, is a fast developing interdisciplinary area. Research and development in this area concerns theory, experiments and applications of DNA computing. DNA computing is fundamentally similar to parallel computing in that it takes advantage of the many different molecules of DNA to try many different possibilities at once. DNA computing also offers much lower power consumption than traditional silicon computers. DNA uses adenosine triphosphate (ATP) as fuel to allow ligation or as a means to heat the strand to cause disassociation. Both strand hybridization and the hydrolysis of the DNA backbone can occur spontaneously, powered by the potential energy stored in DNA. For certain specialized problems, DNA computers are faster and smaller than any other computer built so far. Furthermore, particular mathematical computations have been demonstrated to work on a DNA computer. What makes DNA special is that it is extremely efficient when it comes to storing information in a limited space. Just one milligram of DNA is capable of holding all the printed material in the world. DNA computing is just in its initial stages now with prototypes such as MAYA-II only capable of showing the concept.
7. Teleportation & Wormholes
Teleportation is a term that covers a number or theories and notions concerning the transfer of matter, energy or information between two places without it having to traverse the distance between the two conventionally. A wormhole (stargate) is a hypothetical shortcut through space and time, which is proposed to allow transit that is not locally faster than light (thereby saving conformity with accepted science) but which nonetheless allows near-instant transport between points potentially many light-years apart. This kind of topological shortcut would eliminate objections to teleportation on religious or philosophical grounds, as they preserve the original subject intact and do not raise the problem of duplication. However, a type, Quantum teleportation, or entanglement-assisted teleportation, is a process by which a qubit (the basic unit of quantum information) can be transmitted exactly (in principle) from one location to another, without the qubit being transmitted through the intervening space. The device thus creates a replica of an original thing at a new position and the original thing ceased to exist once the replicas were created. Quantum teleportation is still in its infancy which has been successful on small objects.
Ever since the days of Hippocrates people have been searching for a cure –; a universal remedy, a cure-all. The word ‘;panacea’; comes from the name of Panaceia, the daughter of Asklepios, the Greek god of medicine (whose staff with entwined snake is the symbol of medicine). Panacea is supposed to be a remedy that would cure all diseases and prolong life indefinitely. It was sought by the alchemists as a connection to the elixir of life and the philosopher’;s stone, a mythical substance which would enable the transmutation of common metals into gold. Scientists till now look for panacea in herbs and in nanomedicine. The applications of nanotechnology in medicine are literally endless. Whatever the method they use, imagine a single dose of panacea can cure everything from common cold to cancer to AIDs. This is what all we want.
5. Time Travel
Time travel is the concept of moving between different points in time in a manner analogous to moving between different points in space, either sending objects (or in some cases just information) backwards in time to some moment before the present, or sending objects forward from the present to the future without the need to experience the intervening period (at least not at the normal rate). Although time travel has been a common plot device in fiction since the 19th century, and one-way travel into the future is POSSIBLE given the phenomenon of time dilation based on velocity in the theory of special relativity (exemplified by the twin paradox), as well as gravitational time dilation in the theory of general relativity, it is currently unknown whether the laws of physics would allow backwards time travel.
4. Final Theory
A theory of everything (TOE) is a putative theory of theoretical physics that fully explains and links together all known physical phenomena, and predicts the outcome of any experiment that could be carried out in principle. The theory of everything is better called as the final theory. Many candidate theories of everything have been proposed by theoretical physicists during the twentieth century, but none have been confirmed experimentally. For centuries, physicists have sought to unify the known forces. Currently there are four fundamental forces: electromagnetic, weak nuclear, strong nuclear, and gravity. While the Electroweak Theory by a Pakistani physicist and Nobel laureate Abdus Salam has unified weak nuclear and electromagnetic, the Theory of Everything would require that all four be unified. The primary problem in producing a TOE is that general relativity and quantum mechanics are hard to unify. This is one of the unsolved problems in physics.
3. Simulated Reality
Simulated reality is the proposition that reality could be simulated—perhaps by computer simulation—to a degree indistinguishable from “true” reality. It could contain conscious minds which may or may not be fully aware that they are living inside a simulation. In its strongest form, the “simulation hypothesis” claims it is entirely possible and even probable that we are living in a simulated reality. This is quite different from the current, technologically achievable concept of virtual reality. Virtual reality is easily distinguished from the experience of “true” reality; participants are never in doubt about the nature of what they experience. Simulated reality, by contrast, would be hard or impossible to separate from “true” reality. In brain-computer interface simulations, each participant enters from outside, directly connecting their brain to the simulation computer. The computer transmits sensory data to the participant, reads and responds to their desires and actions in return; in this manner they interact with the simulated world and receive feedback from it. The participant may be induced by any number of possible means to forget, temporarily or otherwise, that they are inside a virtual realm (e.g. “passing through the veil”). While inside the simulation, the participant’s consciousness is represented by an avatar, which can look very different from the participant’s actual appearance. A dream could be considered a type of simulation capable of fooling someone who is asleep. There has been no more influential thought experiment than the so-called “brain in a vat” hypothesis, which has permeated everything from cognitive science and philosophy to popular culture. The experiment asks you to imagine a mad scientist has taken your brain from your body and placed it in a vat of some kind of life sustaining fluid. Electrodes have been connected to your brain, and these are connected to a computer that generates images and sensations. Since all your information about the world is filtered through the brain, this computer would have the ability to simulate your everyday experience. If this were indeed possible, how could you ever truly prove that the world around you was real, and not just a simulation generated by a computer? If you’re thinking this all sounds a bit like The Matrix, you’re right. That film, along with several other sci-fi stories and movies, was heavily influenced by the brain in a vat thought experiment. At its heart, the exercise asks you to question the nature of experience, and to consider what it really means to be human.
2. Space Colonization
Space colonization is the concept of permanent human habitation outside of Earth. Although hypothetical at the present time, there are many proposals and speculations about the first space colony. It is seen as a long-term goal of some national space programs. The first space colony may be on the Moon, or on Mars, or in a space habitat or elsewhere. Ample quantities of all the necessary materials, such as solar energy and water, are available from or on the Moon, Mars, near Earth asteroids or other planetary body. Building colonies in space would require access to water, food, space, people, construction materials, energy, transportation, communications, life support, simulated gravity, and radiation protection. It is likely the colonies would be located by proximity to such resources. The practice of space architecture seeks to transform spaceflight from a heroic test of human endurance to a normality within the bounds of comfortable experience.
1. Perpetual Motion (Infinite Energy)
Perpetual motion –; the solution to all problems, describes hypothetical machines that operate or produce useful work indefinitely and, more generally, hypothetical machines that produce more work or energy than they consume, whether they might operate indefinitely or not. There is undisputed scientific consensus that perpetual motion would violate either the first law of thermodynamics, the second law of thermodynamics, or both. Machines which comply with both laws of thermodynamics but access energy from obscure sources are sometimes referred to as perpetual motion machines, although they do not meet the standard criteria for the name. Despite the fact that successful perpetual motion devices are physically impossible in terms of our current understanding of the laws of physics, the pursuit of perpetual motion remains popular. While the laws of physics are incomplete and stating that physical things are absolutely impossible is un-scientific. The conservation laws are particularly robust from a mathematical perspective. This was proved mathematically by Noether’;s theorem. This means that if the laws of physics (not simply the current understanding of them, but the actual laws, which may still be undiscovered) and the various physical constants remain invariant over time — if the laws of the universe are fixed — then the conservation laws must hold.
