Stephen Hawking made terrifying predictions of the future. Based on science, the late British physicists predicted several things that could happen on Earth, from the rise of powerful Artificial intelligence to fearful robots poised to destroy humankind. Hawking also spoke about how it was dangerous to search for aliens and how global warming could destroy Earth as we know it.
However, Stephen Hawking also spoke about how abrupt advances in genetic science could lead to creating a future generation of superhumans that could eventually destroy humanity as we know it.
In recently published papers, Prof. Hawking predicted that an elite class of physically altered, intellectually powerful humans could come into existence from rich people choosing to edit their existing DNA and manipulate future generations’ genetic markup.

One structure on the dwarf planet Ceres made big news but there is a hitch. It seems that the square-shaped form inside a larger triangle, located in a crater. Everyone else saw it, but the use of artificial intelligence might be a square peg not fitting a round hole. This remark by a Spanish neuropsychologist is questioning the veracity of depending on AI, which might be unsound by SETI.
Ceres is located in the main asteroid belt, a dwarf planet, and the biggest object too. One of its craters, Occator had bright lights which lead to several ideas of what it was. NASA sent the Dawn probe to go close enough to capture visual evidence of what these lights were and solve the mystery. These lights were from volcanic ice and salt eruptions, nothing more.
It gets more interesting as researchers based in the University of Cadiz (Spain) have examined images of these spots. Areas like them are called Vinalia Faculae, in an area where geometric contours are very evident for observers. It now serves as a template to compare how machines and humans perceive images on planetary surfaces in general. Tests like these will show artificial intelligence can see technosignatures of other lifeforms besides human-civilization.
There are so many places and things to explore in the universe! From distant.
exoplanets to faraway galaxies that might host intelligent life, to massive black holes, to.
bright stars. However, there is a problem with space exploration; distance! Everywhere.
you want to go in deep space is far! For example, Elon Musk wants to put humans on.
Mars permanently while NASA wants to send astronauts there. However, any traveler.
going to Mars has to endure a grueling trip through harsh space that lasts not less than.
five months, even with the most powerful rocket in history! If only we could find a faster.
way to travel through space! Also, the next star to us is about 4.5 light-years away.
making it impossible to visit with the current space technologies! However, an.
accidental discovery promises to fix that problem by enabling faster than the speed of.
light travel! What is the discovery, how does it affect space travel, and how does it affect.
you personally? Join us as we explore how NASA scientists accidentally discover the.
world’s first Warp Bubble!
Warp travel is not strange to fans of the Star Trek franchise. The warp drive is a.
charming futuristic technology from Star Trek Universe, which since its first episode in.
1966, includes ten television series and thirteen feature films. In these series and.
movies, characters explore the universe using powerful and fast spaceships, traveling.
from planet to planet and communicating with a crew of aliens. The torsion engine is the.
center of attraction because, without it, the story would be implausible. The universe is.
strange, unimaginable, and insanely large, and even if you want to visit the next star.
the immense cosmic distances create an almost impossible barrier!
Let’s take a look at the next star, Proxima Centauri, 4.5 light-years away. This distance.
means it takes 4.5 years to reach the star if you could manage to attain the speed of.
light! Light flies at full cosmic speed and acts as a sort of universal speed cap, so any.
other method takes longer! In fact, if you decide to use the fastest space probe ever.
built, the long journey through the interstellar void would take nearly eight thousand.
years! So, it makes sense to stay put to Earth and its immediate environment!
Of course, the Star Trek crew didn’t stay close to the Earth because they found a.
solution! This solution makes long-distance travel possible by shortening the distance!
The torsion engine, using warp drive tech, achieves this by juggling space and time.
making for great entertainment! Warp drive was destined to remain imaginary until a.
scientist suddenly realized that such an engine was really possible at the end of the last.
century!
The physicist was Miguel Alcubierre, and he came up with a theory that rocked the.
scientific community globally. In 1994, Alcubierre watched an episode of Next.
Generation while doing his Ph.D. research on Einstein’s general theory of relativity.
where heavy masses can curve space and time. And so Alcubierre picked up a scrap of.
paper, did the calculations, and laid the foundation for an article that appeared in the.
science magazine later that year!
In his paper, Alcubierre describes how you can compress space and time in front of a.
spacecraft and stretch it back behind the ship so that you have to travel a much smaller.
distance to the desired destination safely trapped in what he calls a torsion bubble! In.
visualization, the concept was compared to a surfer riding a wave and a metaphor often.
used to describe how a ship could travel the stars. There is, however, a problem with.
Alcubierre’s warp bubble! You see, the warp engine is tough to build in reality! You can’t.
just curve space forcefully with normal mass! To do so, you need exotic matter, which.
has negative gravity!
Dozens of Warp Engine publications would follow in the following decades. But they.
also remained theoretical exercises and thought experiments that manipulated the.
formulations of the theory of relativity in search of new insights. The need for the foreign.
matter remained!
That was until Eric Lentz, a physicist at the Pacific Northwest National Laboratory in the.
US, stepped in. He watched Star Trek as a kid. However, he has not been able to forget.
How do you power a super advanced alien civilization? Soak up a star.
We harness the power of the sun using solar panels. What if you were to scale this idea to astronomical proportions? Surround an entire star with solar-collecting structures or satellites to power your sprawling alien galactic empire. Such massive structures are known as megastructures—in this case a “Dyson sphere.” We are already trying to detect possible megastructures in space using the dimming of a star and the glow of megastructure components in infrared light. But recent research provides a new detection method—a Dyson sphere may cause its host star to swell and cool.
New findings from the Curiosity Rover’s samples have given scientists another look at distinct carbon signatures found on Mars.
NASA’s Curiosity Rover continues to send back new information about the Red Planet on a frequent basis. The latest discovery brings news of an interesting carbon signature that we didn’t expect to see on Mars. Following analyzations of rock samples returned by the rover, NASA announced that several of the samples are rich in a carbon type that we see on Earth, too. The signature, NASA claims, is most often associated with biological processes, which could give more credence to the possibility of life on Mars.

Of course, like many previous samples recovered from the Red Planet, these new ones continue to raise new questions. It’s worth noting that the existence of the carbon type on Mars isn’t necessarily proof of ancient life. A new study says that the signature could be proof of ancient life. However, it could also just be the result of an interaction between carbon dioxide and ultraviolet light. Additionally, it could be the remnants of carbon left behind after a major cosmic event that happened millions of years ago.
Learnings For Regenerative Morphogenesis, Astro-Biology And The Evolution Of Minds — Dr. Michael Levin, Tufts University, and Dr. Josh Bongard, University of Vermont.
Xenobots are living micro-robots, built from cells, designed and programmed by a computer (an evolutionary algorithm) and have been demonstrated to date in the laboratory to move towards a target, pick up a payload, heal themselves after being cut, and reproduce via a process called kinematic self-replication.
In addition to all of their future potential that has been mentioned in the press, including Xenobot applications for cleaning up radioactive wastes, collecting micro-plastics in the oceans, and even helping terraform planets, Xenobot research offers a completely new tool kit to help increase our understanding of how complex tissues/organs/body segments are cooperatively formed during the process of morphogenesis, how minds develop, and even offers glimpses of possibilities of what novel life forms we may encounter one day in the cosmos.
This cutting edge Xenobot research has been conducted by an interdisciplinary team composed of scientists from University of Vermont, Tufts University, and Harvard, and our show is honored to be joined by two members of this team today.
Dr. Josh Bongard, Ph.D. (https://www.uvm.edu/cems/cs/profiles/josh_bongard), is Professor, Morphology, Evolution & Cognition Laboratory, Department of Computer Science, College of Engineering and Mathematical Sciences, University of Vermont.

In the search for extraterrestrial intelligence (SETI), we’ve often looked for signs of intelligence, technology and communication that are similar to our own. But as astronomer and SETI trailblazer Jill Tarter points out, that approach means searching for detectable techno signatures, like radio transmissions, not searching for intelligence itself. At the moment scientists are considering whether artificial intelligence (AI) could help us search for alien intelligence in ways we haven’t even thought of yet.
As we think about extraterrestrial intelligence it’s helpful to remember humans are not the only intelligent life on Earth. For all we know, chimpanzees have culture and use tools, spiders process information with webs, cetaceans have dialects, crows understand analogies and beavers are great engineers. Non-human intelligence, language, culture and technology surround us to no end. Alien intelligence could look like an octopus, an ant, a dolphin or a machine or, on the other hand, be radically different from anything on Earth.
