Top best answers to the question «Is lightspeed travel possible»

Light can travel at about 300,000 kilometers in one second… Physicist Albert Einstein's famous theory of relativity suggests that it is not possible to travel faster than light.


Those who are looking for an answer to the question «Is lightspeed travel possible?» often ask the following questions:

❔ Why would lightspeed travel?

  • The idea of travelling at the speed of light is an attractive one for sci-fi writers. The speed of light is an incredible 299,792,458 meters per second. At that speed, you could circle Earth more than seven times in one second, and humans would finally be able to explore outside our solar system.

❔ Which electroweak particles travel at lightspeed?

Strictly speaking, only particles without restmass (with rest mass = 0) can travel at the speed of light. If the total particle energy is large compared to the rest energy, the speed of the particle can be rather close to

❔ How long does it take to travel in lightspeed in star wars?

Using traditional rocket fuel, it would take about 50,000 to 70,000 years to reach Proxima Centauri, and nuclear propulsion with proposed technology would get there in about 100 years, Lentz said. A light speed trip would take four years and three months.

Is fast space travel possible?

New research suggests that it might be possible to build warp drives and beat the galactic speed limit. Faster than light travel is the only way humans could ever get to other stars in a reasonable amount of time… The fastest ever spacecraft, the now- in-space Parker Solar Probe will reach a top speed of 450,000 mph.

Is interstellar space travel possible?

As far as we currently know, no it is not. But there are theoretical possibilities that might become reality over the next few centuries. No, it will not be reality by the time you finish school.

Is interstellar time travel possible?

Many scientists suspect that time travel to the past is not possible because of these paradoxes. But if Novikov self-consistency principle stands true, time travel to the past might be possible. It...

Is interstellar travel theoretically possible?

Because of the vastness of those distances, practical interstellar travel based on known physics would need to occur at a high percentage of the speed of light; even so, travel times would be long, at least decades and perhaps millennia or longer.

Is slipstream space travel possible?

Due to the complex nature of slipstream probability and difficulty in mapping slipstream, only biological entities are capable of successfully navigating it. Exiting slipstream near the edge of a galaxy or in certain regions of space could be dangerous because it is difficult to find a slippoint in these areas.

Is time travel actually possible?

Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.

Is time travel even possible?
  • Time travel is possible. Today, we know that time travel need not be confined to myths, science fiction, Hollywood movies, or even speculation by theoretical physicists. Time travel is possible. For example, an object traveling at high speeds ages more slowly than a stationary object.
Is time travel logically possible?
  • Time travel is viewed as "a discrepancy between time and time," where one can move forward or backward in the time continuum without the time traveler's body experiencing the same duration. Even though time travel has not been proven successful in modern day, it is logically and physically possible.
Is time travel metaphysically possible?

Is time travel metaphysically possible? The answer to that question would greatly depend on how one defines the nature of time. If one accepts the traditional view of time—the presentist theory—then time travel would be metaphysically impossible.

Is time travel paradox possible?
  • Time travel with free will is logically possible in our Universe without any paradox, according to new research from the University of Queensland. Physicists seek to understand the underlying laws of the Universe.
Is time travel physically possible?

Wormholes are a plausible way to time travel ,but nobody has found out how to make one. But I ,a 13 year old boy, on the other have created an experiment that can make a wormhole that we can use to time travel. If you want to read the experiment plan follow this link...

Is time travel possible 2020?

Time Travel Theoretically Possible Without Leading To Paradoxes, Researchers Say In a peer-reviewed journal article, University of Queensland physicists say time is essentially self-healing. Changes in the past wouldn't necessarily cause a universe-ending paradox.

Is time travel possible metaphysics?

possible. If time travel is logically impossible then it will also be physically impossible, and in this sense metaphysics can answer questions that physics may not be in a position to address… However, if you are a time traveller, your journey will be measured in terms of personal time and external time.

Is time travel possible now?
  • While time travel does not appear possible — at least, possible in the sense that the humans would survive it — with the physics that we use today, the field is constantly changing. Advances in quantum theories could perhaps provide some understanding of how to overcome time travel paradoxes.
Is wormhole travel theoretically possible?

Wormholes connect two points in spacetime, which means that they would in principle allow travel in time, as well as in space… However, according to general relativity, it would not be possible to use a wormhole to travel back to a time earlier than when the wormhole was first converted into a time "machine".

Why time travel isnt possible?

He argues, too, that going back in time is equally improbable, since to reverse time you would have to decrease, at least locally, the amount of space in the universe.

Will light travel be possible?

Within conventional physics, in accordance with Albert Einstein's theories of relativity, there's no real way to reach or exceed the speed of light, which is something we'd need for any journey measured in light-years. That hasn't stopped physicists from trying to break this universal speed limit, though.

Would time travel be possible?
  • Time travel is theoretically possible, scientists have said. There is no mathematical reason why a time travel machine could not be able to disrupt the spacetime continuum enough to go backwards in time, they suggested.
Is it possible for time travel to be theoretically possible?
  • Physicists have considered time travel to be theoretically possible since Einstein came up with his theory of relativity.
Could time travel ever be possible?

Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.

How could time travel be possible?

Is Time Travel Possible? The Short Answer: Although humans can't hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth.

How interstellar travel will be possible?

To make interstellar spaceflight more reasonable, a probe has to go really fast. On the order of at least one-tenth the speed of light. At that speed, spacecraft could reach Proxima Centauri in a handful of decades, and send back pictures a few years later, well within a human lifetime.

How is time travel theoretically possible?
  • 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, transversable wormholes, and Alcubierre drive .
How possible is a time travel?

Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.

How time travel is theoreticlaly possible?

How Time Travel may be Theoretically Possible. Time travel is nothing special. You’re time traveling right now into the future. Relativity theory shows higher gravity and higher speed can slow time down enough to allow you to potentially travel far into the future.
