The Heisenberg Effect – A Real Time Travel Story” is a video by अंतरिक्ष TV about time travel using a hypothetical device called a time machine. The video is available on Facebook and YouTube

According to the BBC, traveling into the future is possible, but traveling into the past is either impossible or extremely difficult. The Heisenberg uncertainty principle states that you can’t know both momentum or position at the same time, or even after the fact. For example, making a strong measurement changes the particle’s waveform, and going back in time to make a complimentary measurement would invalidate the earlier measurement. 

According to physicist Stephen Hawking, the best evidence that time travel is not possible is that we haven’t been invaded by tourists from the future. However, science does support some amount of time-bending

Do Time travel really happen

According to Space.com, no one has ever demonstrated the kind of time travel seen in science fiction

However, according to Scientific American, the laws of physics say that time travel is possible. Some researchers have created models of time travel that involve wormholes, which are tunnels in spacetime that connect one point in the cosmos to another. 

According to Wikipedia, forward time travel is a well-understood phenomenon, but it’s not feasible to make one body advance or delay more than a few milliseconds compared to another body with current technology. 

According to ScienceBorealis.ca, traveling to the future is possible, but traveling to the past could destroy the future. 

According to Quora, time travel makes things appear from nothing, or disappear into nothing, and that is not possible in our universe. 

According to Carleton.ca, researchers are investigating a more fundamental theory, where time and space “emerge” from something else. This is referred to as quantum gravity, but unfortunately it does not exist yet

Answering this question requires understanding how time actually works – something physicists are far from certain about. So far, what we can say with confidence is that travelling into the future is achievable, but travelling into the past is either wildly difficult or absolutely impossible

Who has ever time travelled

Some people claim to have traveled through time, including:

• John Titor In the early 2000s, Titor claimed to be a US soldier from 2036 in a parallel timeline, sharing photos of his time machine and cryptic warnings about the future. An investigation later concluded that Titor was likely entertainment lawyer Larry Haber. 
• Sergei Krikalev A Russian cosmonaut who has spent 803 days in orbit around the Earth, which means he’s 0.02 seconds younger than others born at the same time. 
• Scott Kelly An astronaut who has spent 520 days in orbit, while his twin brother Mark has spent 54 days. The difference in how fast they experience time has widened the age gap between the two men

Other people who have claimed to have traveled through time include:

• Charlotte Anne Moberly 
• Eleanor Jourdain 
• “Chaplin’s Time Traveller” 
• Present-day hipster at 1941 bridge opening 
• Mobile device in 1943 
• Rudolph Fentz 
• Bob White/Tim Jones 
• Andrew Carlssin 
• Håkan Nordkvist

Russian cosmonaut Sergei Krikalevholds the record for time spent in orbit around the Earth: 803 days. It is calculated that the time dilation caused by his orbital motion means that Krikalev is 0.02 seconds younger than other people born at the same time as him on Earth

How to time travel to the past

According to mainstream science, time travel to the past is impossible. However, some say that time travel is theoretically possible, but travelers wouldn’t be able to change the past in a measurable way. 

Here are some other ways to travel back in time:

• Wormholes A wormhole is a hypothetical passage in space-time that connects two separate points. General relativity predicts that traversable wormholes could exist. 
• Black holes A black hole is a place with extremely strong gravity, so strong that light can’t escape it. The closer you get to a black hole, the more slowly time moves. However, traveling through a black hole is dangerous and one-way. 
• Einstein-Rosen bridges An Einstein-Rosen bridge is not stable enough to travel back in time. Even if it were stable, it would require other physics, which we don’t have. 

Here are some other ways to relive the past:

• Listen to old songs 
• Visit your hometown 
• Read old journals 
• Smell 
• Visit or call your family 
• Reflect and give thanks 

Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives

The Heisenberg effect

The Heisenberg effect is the observation that the act of participating in something changes the game itself. For example, interviewees may give answers they think the interviewer wants to hear

The Heisenberg effect is named after German physicist Werner Karl Heisenberg (1901-76). Heisenberg’s Uncertainty Principle is a physical law that states that it’s impossible to simultaneously know the exact position and exact momentum of a particle. The principle is based on the wave-particle duality of matter. 

The principle states that the more precisely the position of a particle is known, the more uncertain the momentum is and vice versa. This principle is a fundamental reality of quantum mechanics, the study of matter at very small scales

Expressed in the most general terms, the Heisenberg effect refers to those research occasions in which the very act of measurement or observation directly alters the phenomenon under investigation.

What is Heisenberg quantum theory

Heisenberg’s quantum theory, also known as Heisenberg’s uncertainty principle, is a fundamental concept in quantum mechanics that explains why it’s impossible to simultaneously measure more than one quantum variable. For example, it’s impossible to calculate the position and momentum of a small moving object like an electron simultaneously and accurately

The principle only applies to microscopic particles and not to macroscopic particles. For example, the more we nail down the particle’s position, the less we know about its speed. The accuracy of a measurement of the position of an electron is limited by the wavelength of the light illuminating the electron. At the instant of time when the position is determined, the electron undergoes a discontinuous change in momentum. This change is the greater the smaller the wavelength of the light employed. 

The principle is mathematically manifested as non-commuting operators

Introduction. Heisenberg’s Uncertainty Principle states that there is inherent uncertainty in the act of measuring a variable of a particle. Commonly applied to the position and momentum of a particle, the principle states that the more precisely the position is known the more uncertain the momentum is and vice versa

Werner Heisenberg and Erwin Schrödinger are both known for their contributions to the development of atomic theory. Heisenberg developed the first version of quantum mechanics, which describes nature on a microscopic scale, and won the Nobel Prize in 1932 for his work. Schrödinger’s model of the atom laid the foundation for the development of quantum theory, and is known for explaining the energy levels of electrons in an atom

Heisenberg and Schrödinger are also known for discovering the probabilistic nature of the electron and applying it to the model of the atom. Their model represents the atom as a nucleus with protons and neutrons, surrounded by a cloud of electrons. 

Heisenberg formulated quantum mechanics in terms of matrices, and discovered the uncertainty principle, which states that a particle’s position and momentum cannot both be known exactly. The combined uncertainty in both measurements must be equal to or greater than h/(4π), where h is Planck’s constant. 

Schrödinger is also known for the Schrödinger equation, which describes the evolution of the wave function, a quantity that describes the wave properties of a particle. His model assumes that the electron is a wave and tries to describe the regions in space, or orbitals, where electrons are most likely to be found.

Schrodinger and Heisenberg’s work lead to the modern atomic theory, which shows us that regions exist within an atom where electrons are likely to exist. These electron-containing regions that exist around the nucleus are referred to as electron clouds or orbitals

If a particle were to travel back in time, then time moved forward, the particle would no longer be the same because of the uncertainty principle. Time travel into the past also would not guarantee the the particle would end up in it’s original position. This same phenomena would also hold try for larger objects

quantum theory related to time travel?

Some interpretations of quantum mechanics suggest that fundamental physical processes are reversible at the quantum level. While this doesn’t directly lead to time travel, it hints at the possibility of manipulating quantum states to reverse certain events, raising intriguing questions about the nature of time

Nova time travel

Nova is a free digital platform that examines the feasibility of time travel. The program includes an episode called “Time Travel” that discusses whether time travel is possible and the mechanisms that may allow it or prevent it. Nova also has other episodes about time travel, including one featuring an interview with Carl Sagan about the topic

According to NASA, time travel is possible, but not in the way you might expect. Albert Einstein’s theory of relativity says time and motion are relative to each other, and nothing can go faster than the speed of light, which is 186,000 miles per second. Time travel happens through what’s called “time dilation

Who first thought of time travel

The concept of time travel has been around for thousands of years, with some arguing that Oedipus Rex by Sophocles over 2,500 years ago is the first time travel story. The first original Russian science fiction novel, Predki Kalimerosa: Aleksandr Filippovich Makedonskii (The Forebears of Kalimeros: Alexander, son of Philip of Macedon), published in 1836, is also considered the first novel to use time travel

H.G. Wells’ The Time Machine in 1895 popularized the concept of time travel by mechanical means. Spanish writer Enrique Gaspar’s El Anacronópete in 1887 is also considered the first literary inventor of the time machine. 

Many other scientists have been researching time travel and theorizing possibilities, including:

• Frank J. Tipler: Created the theoretical Tipler Cylinder in 1974 
• Ronald Mallett: Has been attempting to synthetically create a black hole to enable time travel since 2015

Time travel makes regular appearances in popular culture, with innumerable time travel storylines in movies, television and literature. But it is a surprisingly old idea: one can argue that the Greek tragedy Oedipus Rex, written by Sophoclesover 2,500 years ago, is the first time travel story

Why is time travel so popular

Time travel is popular because it can provide insight into our lives, and can help us escape difficult situations. Time travel stories can show us what life might have been like if we had taken a different path, or help us deal with big decisions. They can also help us undo mistakes, or explore the possibilities of wish fulfillment

Time travel stories can also be a way to experience different eras and cultures. For example, you might want to travel back in time to Ancient Egypt or the Renaissance to better understand how people lived in the past. 

Time travel has also inspired scientists and researchers to study the possibilities of time travel, and has become a common subject of conversation in scientific and popular culture. For example, Google’s Time Travel Research has the potential to allow scientists and researchers to witness the signing of the Declaration of Independence, the fall of the Berlin Wall, or the formation of the universe itself

Time creates possibilities for us and also terminates possibilities for us. Time is a harsh mistress. We struggle with it every day of our lives and more and more now than ever in the past. So it’s natural for us to turn to these stories to look for some insight or just to get some relief from a difficult reality
