The time travel it is an idea that for centuries ignites our imagination, a pillar of science fiction that continues to inspire countless stories. But how realistic is this fascinating possibility? With the recent scientific findings, we could really see it become a reality in the next century?

Delve into the mystery surrounding this topic. We will explore the concept of the physics of time and, in particular, as the The theory of Relativity of Einstein it revolutionizes our understanding of time travel. We understand what it means time dilatation and how this influence the possibility of time travel into the future.

We will dive into the scientific discoveries current to analyze whether the engineer temporal paradoxeslike the famous paradox of the grandfather, they can be overcome, or whether there are mechanisms that make them impossible. Travel to the past or travel to the future really possible? Join us in this exploration of the frontiers of science to find out how close we are to unravel the secrets of time.

Travel into the Future – Summary

• Einstein's relativity: The video begins by explaining that, according to the theory of Einstein's general relativity, time is flexible and can be distorted by the gravity and velocity [ 00:29]. One example given is that astronauts on the International Space Station get older, slightly more slowly due to their high speed, even if this effect is minimal [ 00:38].
• Theoretical possibilities:
  • Black holes and wormholes: Some physicists theorize that the black holes or wormholes (tunnel space-time) might allow time travel [ 00:57]. However, the video stresses that we have not discovered wormhole and, even if we did, they would probably be unstable and would require an immense energy to keep them open [ 01:06].
  • Quantum mechanics: Other theories suggest that time travel might be possible through the laws of quantum mechanics, but these are highly speculative, and not to try [ 01:25].
• Main obstacles:
  • Technical barriers and energy: There are significant technical barriers and energy. For example, to travel back in time and may require “exotic matter”, that do not even know that it exists [ 01:48].
  • Ethical issues and the logic: If time travel were possible, it would raise many ethical questions, and logical, as the risk of altering the past and create paradoxes such as the “paradox of the grandfather” [ 02:07].
• Conclusion: Although time travel is a concept fascinating, with some support from theoretical, scientific understanding of the current and the immense challenges make it unlikely to become a reality in the next century, as is often depicted in popular culture [ 02:15, 02:34]. However, the video ends with a note of hope, recognizing that science is evolving, and what seems impossible today may be possible in the future [ 02:41].

In this video, we will explore the the future of technology and as the emerging technologies are shaping our world. Discover eight revolutionary discoveries they promise to bring a real technological revolution in the way in which we live and work.

Summary of the video: a Trip in the Future

• Wi-Fi: The video explains how the Wi-Fi, a technology that we often take for granted, has origins in the complex, with the Hollywood actress Hedy Lamarr as surprising a pioneer in its development during the second world war [ 00:59].
• Smartphone: The evolution of the smartphone is traced from the early prototypes of the IBM Simon [ 03:05] to the revolutionary iPhone [ 03:43], highlighting their connection to the virtual and augmented reality.
• Criptovalute: The video defines the criptovalute as Bitcoin, explaining their decentralized nature, based on the technology blockchain and their potential to revolutionize the financial world [ 05:31, 06:00].
• Drones: A time confined to military use, drones have become common, affecting photography, agriculture (precision agriculture), the delivery and operations of security/rescue [ 08:18, 09:41].
• 3D printing: Also known as additive manufacturing, 3D printing is changing the way we produce objects, allowing you to customize in fields such as medicine (dentures, potentially organs) and the construction industry, and by promoting local production and reducing waste [ 10:43, 12:14].
• Artificial intelligence (AI): The AI is no longer just a futuristic concept, but a tangible reality in virtual assistants, facial recognition, recommendation systems, autonomous vehicles, diagnostics, health, security, agriculture, and education, custom [ 13:56, 15:36].
• Electric vehicles (EV): The EV are presented as the future of transportation thanks to their zero emissions at the exhaust, increased efficiency, reduced dependence on oil, the progress of battery technology, lower maintenance costs and government incentives [ 16:51, 18:01].
• Wireless Charging: Based on the electromagnetic induction, wireless charging provides a convenient way to power devices without cables, with the standard “Qi”, which is the most common [ 19:47, 21:04].

The video concludes by pointing out that these innovations are just the beginning, urging viewers to remain informed and to be open to the infinite possibilities that technology offers as we move towards a future of ever more interconnected and advanced [ 22:27, 22:36].

This video tells the amazing story of Vesna Vulović, a flight attendant who in 1972 and is survived an explosion in the air and a drop from 10.160 feet tall [ 00:24]. The aircraft of JAT Yugoslav Airlines broke in flight because of a bomb in the luggage compartment [ 00:10].

Here is a summary of the events:

• The incident: The aircraft disintegrated at an altitude of 10.160 m and Vesna is precipitated along with the wreckage, was eventually found alive [ 00:24, 00:27].
• Rescue and recovery: A former German soldier has provided first aid to keep open the respiratory tract until the arrival of the rescuers [ 00:31]. Vesna has reported numerous fractures, including the legs and spine, and has remained in a coma for several days [ 00:39].
• Consequences: After an intense rehabilitation, it is able to walk again [ 00:43]. Vesna Vulović is the entry in the Guinness book of records for its survival [ 00:51]. Passed away in 2016 at the age of 66 years [ 00:54].

This video tells the story of Larry, a blade with the unusual dream to become an astronaut and explore space [ 00:00].

Here is a summary of the adventure of Larry:

• The construction of the Rocket: Inspired by the science-fiction film, Larry has decided to build a rocket using cans of soda, tape, and an old SATELLITE as an on-board computer [ 00:07]. With the help of his friend, the engineer Pedro, have completed the rocket, but they forgot to calculate how much it would be back on Earth. [ 00:15].
• Space travel and Fame ViralDespite the oversight, Larry is launched into space, where he waved and sent a video of himself [ 00:26]. These videos have become viral on YouTube, [ 00:31].
• The intervention of the NASA: The viral videos have attracted the attention of NASA, which has decided to send a rescue mission [ 00:33].
• New Friends: Larry landed on a planet and struck up a friendship with a group of blade space-aliens [ 00:37].
• Meeting with the Astronauts and Party: Astronauts have landed and have met Larry, who invited them to join him. [ 00:43]. The astronauts were at a party space with the blade aliens [ 00:47].
• The Decision to LarryAlthough astronauts have tried to convince Larry to return to Earth, he decided to stay with her new friends and Magma [ 00:51].

This video covers the concept of ideal weight for athletes, stressing that do not necessarily correspond to that of the common people [ 00:00]. The reason for this is that muscle weighs more than fat [ 00:07]. Therefore, an athlete can weigh more despite being in perfect physical shape [ 00:10]. The video should not focus solely on the number indicated by the scale [ 00:14].
