Time travel is possible according to physicists

"The time travel are possible, of course.But with a little nuance, we still do not have enough technology and, first of all, we must be clear that the trip can only be directed towards an address: the future ».

This is the summary of what several scientists give us about the always fascinating time travel.An exciting topic that leaves us always spectacular movies, unforgettable books and great unknowns like the ones we have raised in Science Daily Online, as is the case of "the Philadelphia experiment" or "the time traveler in the photograph of 1941.So today , we are going to put aside these famous enigmas to find answers in the physicists themselves.

Will only future trips be possible?

You may know the British professor and particle physicist Brian Cox. He is very popular in the English media, pr This is an interesting scientific outreach program and is currently part of the experiments at CERN (European Council for Nuclear Research) in Switzerland, from which we expect great results.these concepts of time travel and, as such, it is very common that their presence is almost constant in festivals and science meetings in which this idea is treated.So what is the opinion of this reputed physical particle?

Time travel is possible according to physicists

Professor Brian Cox

Time travel will be possible, it is not a far-fetched concept, but today we have no clear evidence that they have managed to occur.A few years ago Stephen Hawking himself also reached the same conclusion, after performing a simple and illustrative experiment.We must also remember the subli I felt the humor of the illustrious scientist.What was his test based on? Very simple: On June 28, 2008, I celebrated a party at his house near the University of Cambridge...and no one attended, despite having large tables full of canapes and champagne , nobody went to the appointment.And what was the reason? Hawking sent the invitations once finished, spreading the event even through social networks, with the idea of checking if a traveler travels in time to the event.But it did not happen.

What was the use of this to Stephen Hawking? Basically, to give an example that time travel to the past is impossible.Brian Cox also comes to the same conclusion, machines can be built in time but just to travel to the future, there where you will have total freedom of movement, but how is it possible? In his own words, we would have to rely on the well-known theory of relativity of Albert Einstein. Something would be achieved only if we were able to travel at an incredibly fast speed, close to the speed of light.If you travel fast enough, the clock will be delayed with respect to the people who are still in the current moment.The closer we get to the speed of light, we will be able to see how our watches are moving so slowly that we would be able to go beyond 10,000 years into the future.Incredible, right?

Time travel and wormholes

But what about wormholes? ? Couldn't they be a means of going back in time? They are huge and interesting dimensions similar to shortcuts through time and space, why not? An interesting idea that physicists, today, come with skepticism.In fact, Stephen Hawking himself continues to maintain the idea of the "conjecture of chronological protection", through which, travel in the past they would not be possible through wormholes.Now, other scientists like Eric W.Davis, of the International Institute for Advanced Studies EarthTech, tell us that they would be the best means to go back in our days, it would only take something almost extraordinary: «turn a wormhole into a time machine».

Time travel is possible according to physicists

And what about that interesting project carried out at CERN with the Large Hadron Collider ? Professor Brian Cox is part of it and tells us, simply, that this medium could allow us to find new dimensions.Something that would show us, for example, that we may be living in "a three-dimensional space." But we must wait to witness of such great discoveries.Meanwhile we remain with the incognito and with the dreams, with those dreams that bring us the DeLorean of Marty Mcfly or the fabulous Tardis of Doctor Who, able to travel in time and space.Knowing whether or not time travel has taken place today, is still material conspiracy theories, but even so it is worth addressing them, so soon we will bring you what has been done in the Montauk project, experiments supposedly carried out to continue what started in the Philadelphia experiment.

And now tell us do you really think that can we never travel to the past ? What would you prefer, traveling to the past or the future? As always, we await your comments.

The mystery of the giant Siberian crater

It was in July 2014.A helicopter flew over the western part of Siberia, specifically in an area of Yamal, when, suddenly, they distinguished something strange.Something had appeared out of nowhere and seemed to open its jaws from a quiet white stage.It was a crater, a gigantic abyss 60 meters in diameter and about 50 meters deep. What was its origin? What had caused such a hole in the middle of that cold and desolate area ? The news then began to spread through the media around the world, awakening all kinds of theories, from those based on a possible extraterrestrial origin, to those of those who thought, calmly and serenely, that it was best to descend inside the crater and initiate the relevant investigations.

The real reason why babies cry at night

All of us who have been parents know that the first months of the baby are usually the most intense and exhausting, among other things because the nights of continuous sleep are interrupted for a good time, at least until the baby gets used to sleeping run and in another room, as many pediatricians recommend.And also because you know that it is very stressful when babies cry at night. Here we talk about the reasons that usually explain this crying, along with a new and controversial hypothesis. The real reason why babies cry at night The traditional reasons used to explain why babies cry at night can be summed up in four causes: 1.Sleep dynamics In the first months, the baby goes from a two-phase sleep cycle (active sleep and quiet sleep), to the adult, five-phase ; this transition can generate alterations in the infant, and crying on waking. 2.Hambre Even feeding them well with breast or some replacement of breast milk, especially during the first months , it is likely ...
