What if someone could travel at twice the speed of light?

Sam Baron is an associate professor at the Australian Catholic University. This expert has published an article Conversation Where a question is asked: what if a Can travel at twice the speed of light?

“As far as we know, It is not possible for a person to walk twice the speed of light., In fact, for any object with mass it is not possible that you or I would have to move faster than the speed of light,” Baron says.

“However, for some strange particles, it may be possible to travel at twice the speed of light, and can send those particles back in time“, experts say.

For some strange particles, it may be possible to travel at twice the speed of light, and this could send those particles back in time.

As Baron explains, “One of the best physical theories we have at the moment is the theory of relativity, developed by Albert Einstein. According to this theory, the speed of light serves as a universal speed limit For anything with flour.”

“Specifically, relativity tells us that nothing with mass cannot move at the speed of light. To accelerate an object with mass, we have to add energy, We want the object to go faster, the more energy we need,” Baron continues.

“The equations of relativity tell us that anything with mass, no matter how massive, would require an infinite amount of energy to accelerate it to the speed of light. But all energy sources that we know of are finite: are somehow limitedThe author says.

“In fact, it is plausible that the universe contains only a finite amount of energy. This would mean that There is not enough energy in the universe to accelerate to the speed of light with mass,” Baron says.


“This universal speed limit applies to anything we might call ‘ordinary mass.’ However, there are hypothetical particles called tachyon With a special type of flour called ‘imaginary flour’. There is no evidence that tachyons exist. But according to relativity, their possible existence cannot be ruled out,” the authors say.

“If they exist, tachyons must always be moving faster than the speed of light. Just like nothing with normal mass can move at the speed of light, tachyons they can’t be less than the speed of lightBaron continues in his article.

Baron recalls that “some physicists believe that if Tachyons existed, they would be constantly traveling backwards in time. This is why Tachyon Many science fiction books and movies are associated with time travel.,

an imaginary time machine

“There are ideas that one day we might use tachyon to build a time machine, But for now it’s still a distant dream, as we don’t have the ability to detect potential tachyons.”

“It’s disappointing that we can’t travel faster than the speed of light. The closest star to us other than the Sun isIt is 4.35 light years away. Therefore, traveling at the speed of light, it would take more than four years to get there,” the authors say.

“The Farthest Star We’ve Found 28 billion light years away. So we can skip mapping the whole universe. That said, relativity allows the existence of a ‘wormhole’, the author said.


“The wormhole is a shortcut between two points in space. While a star may Simply 4.5 light years away, It may be only a few hours away through a wormhole,” Baron continues.

“If there are real wormholes, they allow us to travel great distances in a very short amount of time, allowing us to reach the farthest reaches of the universe in a single lifetime. Unfortunately, Tachyon, like wormholes be completely fictional”The author adds.

“Although we can’t actually travel faster than light, we can try to imagine what it would be like to do so. Thinking this way, we engage in a ‘counterfactual thinking’. We are looking at how things would have been or could have happened had the reality been any different.”

“There are so many different possibilities that we can consider, each with a different set of physical principles. So we can’t say for sure what will happen.” If only we could travel faster than light. At best, we can guess what might happen. Shall we begin time travel, as some scientists believe the Tachyons can?”
