Will time travel be possible in the future, like in 2060?
There are edge cases in theoretical physics where an elementary particle could conceivably travel backwards in time, but only under certain very extreme conditions of energy and gravity. Time travel, in form of dilation, is definitely possible. However, traveling back to a certain point is improbable.
Yes, time travel is possible in some ways, but it’s not likely to be the same as what’s depicted in movies:
- Traveling into the futureAccording to Einstein’s theory of relativity, it’s possible to travel into the future by traveling at speeds close to the speed of light or spending time in a strong gravitational field. This is because time passes more slowly for those traveling at high speeds or experiencing strong gravity.
- Traveling into the pastWhile it’s theoretically possible to travel back in time in some scenarios, it’s considered very difficult or impossible. Some theories suggest that wormholes, cosmic strings, and Alcubierre drives could allow for time travel to the past. However, wormholes are theoretical and scientists haven’t found any yet.
- Real-world time travelTime dilation is a real-world example of time travel that occurs when time passes at a different rate for different people. For example, astronaut Scott Kelly aged more slowly than his twin brother Mark because he spent 520 days at the International Space Station traveling faster than Mark.
Is time travel possible?
We all travel in time. During the last year, I’ve moved forward one year and so have you. Another way to say that is that we travel in time at the rate of 1 hour per hour.
But the question is, can we travel in time faster or slower than “1 hour per hour”? Or can we actually travel backward in time, going back, say 2 hours per hour, or 10 or 100 years per hour?
It is mind-boggling to think about time travel. What if you went back in time and prevented your father and mother from meeting? You would prevent yourself from ever having been born! But then if you hadn’t been born, you could not have gone back in time to prevent them from meeting.
The great 20th century scientist Albert Einstein developed a theory called Special Relativity. The ideas of Special Relativity are very hard to imagine because they aren’t about what we experience in everyday life, but scientists have confirmed them. This theory says that space and time are really aspects of the same thing—space-time. There’s a speed limit of 300,000 kilometers per second (or 186,000 miles per second) for anything that travels through space-time, and light always travels the speed limit through empty space.
Special Relativity also says that a surprising thing happens when you move through space-time, especially when your speed relative to other objects is close to the speed of light. Time goes slower for you than for the people you left behind. You won’t notice this effect until you return to those stationary people.
Say you were 15 years old when you left Earth in a spacecraft traveling at about 99.5% of the speed of light (which is much faster than we can achieve now), and celebrated only five birthdays during your space voyage. When you get home at the age of 20, you would find that all your classmates were 65 years old, retired, and enjoying their grandchildren! Because time passed more slowly for you, you will have experienced only five years of life, while your classmates will have experienced a full 50 years.
So, if your journey began in 2003, it would have taken you only 5 years to travel to the year 2053, whereas it would have taken all of your friends 50 years. In a sense, this means you have been time traveling. This is a way of going to the future at a rate faster than 1 hour per hour.
Time travel of a sort also occurs for objects in gravitational fields. Einstein had another remarkable theory called General Relativity, which predicts that time passes more slowly for objects in gravitational fields (like here on Earth) than for objects far from such fields. So there are all kinds of space and time distortions near black holes, where the gravity can be very intense.
In the past few years, some scientists have used those distortions in space-time to think of possible ways time machines could work. Some like the idea of “worm holes,” which may be shortcuts through space-time. This and other ideas are wonderfully interesting, but we don’t know at this point whether they are possible for real objects. Still the ideas are based on good, solid science. In all time travel theories allowed by real science, there is no way a traveler can go back in time to before the time machine was built.
I am confident time travel into the future is possible, but we would need to develop some very advanced technology to do it. We could travel 10,000 years into the future and age only 1 year during that journey. However, such a trip would consume an extraordinary amount of energy. Time travel to the past is more difficult. We do not understand the science as well.
Actually, scientists and engineers who plan and operate some space missions must account for the time distortions that occur because of both General and Special Relativity. These effects are far too small to matter in most human terms or even over a human lifetime. However, very tiny fractions of a second do matter for the precise work necessary to fly spacecraft throughout the solar system.

Will time travel be possible in the future, like in 2060?
If time travel were possible we would have heard of it a long time ago. People would have been traveling to various points in the past for millenia and more.
There have been 1 or 2 instances of suspected time travel. But nothing was ever proven.
Now, if we could only see projections and not participate, that would be different! So, for instance, maybe time travel just means that I can watch what’s happening at [for example] my address in my bedroom, 40 years ago. I’ve only been here 10 years. Or maybe I could step into Hitler’s office or Einstein’s lab or Cleopatra’s ship or whatever AS AN OBSERVER [like watching a movie, but for real].
IF that were the case [and I am NOT saying that it is] that would still be incredibly useful! I’ve never seen 3 of my grandparents. I would love to see them, hear them,etc. as they went about their daily lives. I wouldn’t be able to change anything. But just seeing them as real, living persons, not just old black & white photos, would change MY life for the better.
I bet that someone’s already figured out that type of time travel. But, if it were me, I’d not tell anyone about it, ever!
I don’t think that anyone will figure out how to travel through time, by 2050.
Einstein’s theory is that spacetime is a single & singular fabric. So, for instance, any & every point in space exists SIMULTANEOUSLY & ETERNALLY in every moment in time. Moreover, according to Al, time exists ONLY in space. No space, no time.
Therefore, it may be possible to travel through space to get to a specific point in time, without ever leaving a specific point in space. Think of it as drilling through space to get to a point in time.
This, I think, will eventually happen. But it will not happen in or before 2050.
What would be really interesting to me would be to see if we can travel through time to different points in space! Can we be in 2 places at the same time? Al felt that it was possible. The theory is that you don’t need machines [cars, trains, airplanes, spaceships, etc.] to travel through space.
All you need to do is to create a time-slide such that you can slide through time to your destination. How do you create a time-slide? I wouldn’t be here if I could answer that! The theory is that it’s not only possible but it MUST be possible to create such a slide. Most likely, such slides exist already and we just have never figured out where they are or how to use them!
But we will

Is time travel possible?
It is unlikely that time travel will be possible in the future, even in 2060.
There are a number of reasons why time travel is thought to be impossible. One reason is that it would violate the laws of causality. For example, if you could travel back in time and kill your grandfather before he met your grandmother, then you would never have been born. This is a logical contradiction.
Another reason why time travel is thought to be impossible is that it would require faster-than-light travel. This is also thought to be impossible, because it would violate the laws of physics.
Some physicists believe that it may be possible to travel to the future, but not to the past. This is because the laws of physics do not explicitly forbid travel to the future. However, even travel to the future is thought to be very difficult.
Overall, it is very unlikely that time travel will be possible in the future, even in 2050. There are a number of fundamental problems with time travel that make it seem impossible.
Some physicists believe that it may be possible to travel to the past or the future if we can create wormholes. Wormholes are hypothetical tunnels through spacetime that could connect two different points in space or time. However, wormholes are also thought to be very unstable and difficult to create.
Another possibility is that we may be able to travel to the future by traveling very close to the speed of light. This is because time dilation occurs when an object travels close to the speed of light. This means that time passes more slowly for the object than it does for objects that are stationary. However, even if we could travel very close to the speed of light, it would still take a very long time to travel to another star system.
Overall, it is very unlikely that time travel will be possible in the future, even in 2050. There are a number of fundamental problems with time travel that make it seem impossible. However, some physicists continue to work on theories that may one day make time travel possible.
Time travel is a fascinating concept, but it is very unlikely that it will be possible in the future, even in 2050. There are a number of fundamental problems with time travel that make it seem impossible. However, some physicists continue to work on theories that may one day make time travel possible. Time travel is a fascinating concept that has been explored in science fiction and theoretical physics.
Here’s a brief overview of the current understanding:
- Relativity and Time Dilation: According to Einstein’s theory of relativity, time can be affected by speed and gravity. For example, as an object approaches the speed of light, time for that object slows down relative to a stationary observer. This has been experimentally confirmed with atomic clocks.
- Wormholes: Some theoretical models suggest the existence of wormholes, which could potentially connect different points in time and space. However, this remains purely speculative and has not been demonstrated.
- Grandfather Paradox: Time travel raises philosophical and logical issues, such as the grandfather paradox, where a time traveler could potentially prevent their own existence.
- Current Science: As of now, there is no experimental evidence that practical time travel is possible. It remains a topic of theoretical exploration rather than a feasible reality.
While the idea of time travel captivates the imagination, it currently resides more in the realm of theory and fiction than practical science.

Russian Cosmonaut already lives in FUTURE – proving time travel IS possible
One way to achieve time travel into the future would be travelling at the speed of light in space, as first theorised by Albert Einstein.
Indeed Cosmonaut Sergei Krikalev technically lives in the future due to his extended period on the International Space Station.
After spending almost 804 days in space arrived back in Earth 0.02 seconds in the future thanks to a process known as time dilation.
Under accepted theories of time travel engineers would have to build a space ship which could travel at the speed of light (186,000 miles-per-SECOND), and head out into space.
Theoretical physicist and string theorist Brian Greene, of Columbia University, said: “You can build a spaceship, go out into space [and travel] near the speed of light, turn around and come back.
Time travel, as depicted in science fiction, faces major scientific challenges. According to our current understanding of physics, time travel to the past or future remains speculative.
1. **General Relativity**: Albert Einstein’s theory of general relativity allows for the possibility of time distortions, such as time dilation (where time moves differently depending on speed and gravity). However, it doesn’t easily support traveling back in time or creating “closed time-like curves” (essentially loops in time). Wormholes, theoretical tunnels through spacetime, have been proposed as a possible mechanism for time travel, but they’re still entirely hypothetical and require exotic matter that hasn’t been discovered.
2. **Quantum Mechanics**: Some interpretations of quantum mechanics suggest possibilities like “many worlds” or parallel universes, where time travel might affect different timelines, but these ideas are far from being practically realizable.
3. **Causality and Paradoxes**: The concept of time travel raises major paradoxes, such as the famous grandfather paradox (where you might prevent your own existence by changing the past). These unresolved paradoxes pose serious logical issues for practical time travel.
By 2050, breakthroughs in physics might deepen our understanding of time and spacetime, but as of now, time travel remains an area of theoretical exploration rather than imminent reality. Most scientists remain skeptical about practical time travel happening any time soon, if ever.
Will time travel be possible in the future, like in 2060?
