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 it travel at twice the speed of light?
“As far as we know, It is not possible for a human to travel 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,” says Baron.
“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 can send those particles back in time.
As Baroni 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 can move at the speed of light. To accelerate an object with mass, we need to add energy“The faster we want the object to go, 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 sources of energy that we know are finite: are somewhat limitedThe author says.
“In fact, it is plausible that the universe contains only a finite amount of energy. This means that There is not enough energy in the universe to accelerate to the speed of light with mass,” says Baron.
tachyon
“This universal speed limit applies to anything we can call ‘ordinary measure.’ 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 excluded”, say the authors.
“If they exist, tachyons must always be moving faster than the speed of light. Just as nothing of normal mass can move at the speed of light, tachyons they cannot be less than the speed of lightBaron continues in his article.
Baroni recalls that “some physicists believe that if Tachyons existed, they would constantly travel back in time. That is why Tachyon Many science fiction books and movies are related to time travel.,
an imaginary time machine
“There are ideas that one day we could use tachyons to build a time machineBut for now it’s still a distant dream, as we don’t have the ability to detect potential encounters.”
“It’s disappointing that we can’t travel faster than the speed of light. The nearest star to us besides 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 most distant star we have found 28 billion light years away. So we can skip the map of the entire universe. That said, relativity allows for a ‘wormhole’ to exist, the author said.
worms
“A wormhole is a shortcut between two points in space. While a star can Just 4.5 light years away, It could be just hours away from a wormhole,” Baron continues.
“If there are true worms, they allow us to travel great distances in a very short 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 cannot actually travel faster than light, we can try to imagine what it would be like to do so. By thinking this way, we engage in a ‘counterfactual thinking’. We are looking at how things would have been or could have happened if the reality was 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. Should we start time travel, as some Tachyons scientists believe?
