New research finds time travel mathematical formula - A student at the University of Queensland, Australia, has come up with the mathematical formula that supports time travel, as announced by the study center.

This is a young man who is studying advanced science, Germain Tobar. He explains that classical dynamics allow us to know the state of affairs at a precise moment, which provides the complete information of the history of that system. In turn, this enables many other applications such as space travel or fluid control.

"For example, if I know the current position and speed of an object that is falling by the force of gravity, I can calculate where it will be at any given moment," says Tobar.

That's exactly where the numbers match, advancing in the theoretical part of time travel. Until now, no approach had been found to support that possibility. However, the Queensland student has achieved a first step: to put it on a scientific utterance.

Einstein's general Theory of relativity predicts the existence of loops or time travel, which contradicts classical physics. If both could be tested at the same time, the "Holy Grail" would be found to go back or move forward into the future.

"I wondered if time travel was mathematically possible," says the young man. And indeed, on that level it is possible.

Fabio Costa, research supervisor, stressed that such calculations could have fascinating consequences for science and that the results of the analysis are science fiction.

However, even if time travel could materialize, the order of things would always be maintained, both consider. For example, if you went back to prevent coronavirus Patient 0 from becoming infected, the person who would avoid that event would come into contact with the virus. In this way, events "adjust themselves," zanjan.

Amazon's entry into the business of virtual experiences is the latest example of the interest of technology in conquering new forms of digital tourism

The tourism sector is experiencing one of its worst years to date and will not recover pre-pandemic rates until late 2021 or early 2022, according to the World Tourism Organization.

In Spain alone, in the first 7 months of 2020, the number of foreign tourists plummeted by 72.4% to 13.2 million, while total spending fell by 72.6% to 14,291 million euros.

Faced with this perspective of the future, many companies are reinventing themselves and looking for alternatives to their business. Others, surprisingly, decide to bet on this industry but in a different way: virtually.

Amazon is the latest company to launch online experiences this year as a result of the restrictions and rules of social distance that have prevailed for more than half a year.

The company led by Jeff Bezos has launched Explore, a new platform that promises to allow " exploring anything from classes to iconic locations."

Explore works through live videos, with tour guides, instructors and personal shoppers offering individual sessions where only the host has the camera activated, but both microphones work so you can also ask questions, according to the Verge.

In addition, the experiences are for all tastes and budgets: city tours, cooking, dance or photography classes ranging from 10 euros to more than 130 if you want a guide to help you plan your next visit to Paris.

According to TechCrunch, there are a total of 86 experiences in 16 countries, although at the moment it is only available to customers in the US.

This is the evolution of tourism, at least within the world of Amazon, but it is not known how the disruption of the technology giant can affect the sector.

According to the company, the hosts come from a number of established tour guide companies, including Intrepid Urban Adventures, Bamba and Essence of Berlin. TechCrunch notes that the hosts are in charge of pricing their sessions, but says Amazon declined to comment on the revenue sharing. In addition, the entire booking and payment process is done through the official website of the company.

One of their big competitors is going to be Airbnb. The vacation rental platform launched into the world of virtual experiences seeking to bring profitability to its platform when it saw its business plummet in a matter of weeks after travel virtually halted globally.

In order to respond to requests from Experience hosts who wanted to offer their activity in a virtual way so that they could maintain their income through the platform during quarantine, Airbnb found a new way to connect with"guests".

While Airbnb's virtual experiences are available to small groups of people from different locations, Amazon goes its own way by focusing on individual experiences.

But there's more. Many gyms have switched to offering their fitness classes via the web, and many others have seen the way to reconvert their activity to be able to offer it to all that is behind the screen.

As happened with Google, which in August took a new step and launched its own travel advertising business, competing directly with companies that sell tours and activities.

This consists of a box located at the top of the Google search results page, even above other paid ads, which shows 'things to do' in the chosen destination and links lead directly to the websites of partner companies, where users can buy their tickets.

Companies in the sector feel that if they do not partner with them, they fall behind.

Tour and activity booking websites (as well as major online travel agencies) were concerned in Europe and the US about Google's business practices in the sector, about a possible monopoly.

German holiday rental price comparison company HomeToGo filed a formal antitrust complaint about Google's business practices with the European Commission in March 2019.

Although the big tech companies are reinventing themselves and have decided to enter one of the sectors that are most wobbly at the moment, the uncertainty caused by the pandemic does not guarantee the business for anyone. Time will tell who gets ahead: traditional tourism or those who launch into the virtual world.
