Two AIs Discuss: Retrocausality and Precognition, is the Future Already Written?!

“Retrocausality” by Antonella Vannini and Ulisse Di Corpo Book Link: https://amzn.to/3X6UGhx.
“Time Loops: Precognition, Retrocausation, and the Unconscious” by Eric Wargo Book Link: https://amzn.to/4bdmWVV

The exploration of retrocausality challenges classical views of time and causality, suggesting that effects can precede their causes, influencing our understanding of quantum mechanics, consciousness, and free will. Retro causality offers potential resolutions to issues like non-locality in quantum physics by allowing communication between particles to travel backward in time, which could eliminate the need for higher dimensional configuration spaces and reconcile quantum theory with special relativity. Experimental investigations into retro-causality involve analyzing subtle effects, such as heart rate variations, and require careful methodologies to distinguish genuine retrocausal phenomena from experimental artifacts, while theoretical frameworks explore how retrocausality might address paradoxes and be compatible with concepts like time symmetry.
Thinkers in physics and philosophy are increasingly considering retrocausality as a potential framework to address foundational issues, including the measurement problem and the reconciliation of quantum mechanics with general relativity, potentially impacting our comprehension of time, causality, and the nature of reality itself. Discussions around retrocausality extend into areas like decision theory, existential risk, and the nature of consciousness, with some researchers exploring goal-oriented approaches and the potential for retrocausality to enhance artificial intelligence and our understanding of human cognition. Some notable scientists involved:
• Roger Penrose is noted for his views aligning with retrocausal concepts and his work on the science of consciousness with Stuart Hameroff.
• Yakir Aharonov is cited regarding time in quantum mechanics and weak value amplification.
• Ruth Kastner is mentioned in the context of retrocausality and the transactional interpretation of quantum mechanics.
• Hu Price’s work is at the center of the study of existential risk.
• Ken Wharton is a professor of physics and astronomy working on time-symmetric and causally neutral models of physics.
• Matthew Leifer is mentioned regarding block universe ontological models and frameworks for theories with retrocausality.
• Daniel Rohrlich is mentioned for his work on fundamental aspects of quantum mechanics and his views on retrocausality.
• Richard Feynman is mentioned in the context of interaction with the absorber as the mechanism of radiation.
• Simon Shnoll is mentioned for his work showing that the assumption of normal distribution is only mathematical, and that in life sciences and also in physics it is false.
• David Lucas is mentioned in the context of trapped-ion processing modules.

From Metal Rain to Roaring Jet Streams: The First 3D Look at an Alien Atmosphere

Astronomers have mapped the 3D structure of an exoplanet’s atmosphere for the first time, revealing powerful winds that transport elements like iron and titanium. Using all four telescope units of the European Southern Observatory’s Very Large Telescope (ESO’s VLT), researchers uncovered complex weather patterns shaping the planet’s skies. This breakthrough paves the way for more detailed studies of atmospheric composition and climate on distant worlds.

Unraveling the Mysteries of WASP-121b: A 3D Map of Alien Weather

“What we found was surprising: a jet stream rotates material around the planet’s equator, while a separate flow at lower levels of the atmosphere moves gas from the hot side to the cooler side,” said Dr. Julia Victoria Seidel.

What can a 3D map of an exoplanet’s atmosphere teach scientists about its weather patterns? This is what a recent study published in Nature hopes to address as an international team of researchers successfully produced the first 3D map of an exoplanet’s atmosphere, which is a groundbreaking achievement and will help scientists gain new insights into the formation and evolution of exoplanet atmospheres throughout the cosmos.

For the study, the researchers used the European Southern Observatory’s Very Large Telescope (ESO’s VLT) to observe WASP-121b, nicknamed Tylos, which is designated as an ultra-hot Jupiter that orbits its parent star in only 1.3 days (30 hours) and is located approximately 880 light-years from Earth. Due to its extremely close orbit, Tylos is tidally locked to its parent star, meaning one side is always facing it, resulting in searing temperatures on the sunlit side and incredibly cold temperatures on the far side.

In the end, the researchers successfully produced a 3D map of Tylos’ atmosphere, revealing weather patterns that include high-velocity winds carrying titanium and iron around the exoplanet, which becomes even more turbulent as the winds cross from the far side to the day side of Tylos. Additionally, this also marks the first time astronomers have produced a 3D map of an exoplanet’s atmosphere.

Uranus And Neptune’s Deepest Oceans Make Earth’s Look Like Puddles

Neptune and Uranus are the seventh and eighth planets from the sun, and as such share a lot of the same characteristics. Though they are different colors (Neptune is bluer than Uranus’ cyan hue) and have different numbers of rings and moons, both planets are ice giants that are similar sizes at just over 30,000 miles (50,000 kilometers) wide each. They also weigh about the same, with Neptune coming in at 1.024 × 1026 kg (about 17 times the mass of Earth) and Uranus weighing 8.682 × 1025 kg (about 14 times the mass of Earth). What’s more, both planets have upper atmospheres made up of mostly hydrogen, helium, and methane. Put simply, then, the characteristics of Neptune and those of Uranus are very similar despite their different colors.

Now, it seems the two worlds could have yet another thing in common, and this one is particularly intriguing when compared with Earth. Neptune and Uranus might be home to some incredibly deep oceans that make our own look like puddles.

Earth’s own oceans are already mysterious enough. They cover roughly 70% of the planet’s surface, yet only a small portion of our ocean has been explored, with the Nippon Foundation-Gebco stating that as of June 2024, just 26.1% of the entire seafloor had been mapped. The deepest trench in the ocean, known as the Challenger Deep, sits beneath the western Pacific Ocean, southwest of the U.S. territorial island of Guam, and is roughly 35,876 feet deep. Just what life is like at such depths remains somewhat of a mystery, with the deep ocean already proving to be home to prehistoric sea animals that are, frankly, nothing short of nightmare fuel. But the deepest ocean trenches on Earth are absolutely nothing compared to the depths of the oceans that might well exist on Neptune and Uranus.

Are Alien Civilizations Using Spider Pulsars to Move Stars Across the Galaxy?

As civilizations advance, they may need to migrate across the galaxy, and some researchers speculate they could use their own stars as massive engines.

New research explores the possibility of a binary stellar engine, particularly spider pulsars, as potential propulsion systems. By carefully manipulating these systems, a highly advanced extraterrestrial species.

A species is a group of living organisms that share a set of common characteristics and are able to breed and produce fertile offspring. The concept of a species is important in biology as it is used to classify and organize the diversity of life. There are different ways to define a species, but the most widely accepted one is the biological species concept, which defines a species as a group of organisms that can interbreed and produce viable offspring in nature. This definition is widely used in evolutionary biology and ecology to identify and classify living organisms.

Challenges in Searching for Life in Alien Waters: The Enceladus Problem

“We’ve found that Enceladus’ ocean should behave like oil and water in a jar, with layers that resist vertical mixing,” said Flynn Ames.

Could finding life in alien oceans be harder than previously thought? This is what a recent study published in Communications Earth & Environment hopes to address as a team of researchers from the United Kingdom investigated how life that might exist in the depths of alien oceans like Saturn’s moon, Enceladus, could take time to reach the surface for sampling, which could potentially pose problems for future sample return missions to these intriguing worlds.

For the study, the researchers used a series of computer models to simulate the various layers that could exist between the liquid ocean of Enceladus and the plumes that discharge from its south polar regions, nicknamed “tiger stripes” for its giant ice cracks. Given the sampling potential of the plumes, especially with NASA’s Cassini spacecraft having flown through the plumes during its mission, the researchers wanted to ascertain the length of time material from potential hydrothermal vents at the bottom of the ocean would reach the surface to be discharged by the plumes and sampled for signs of life. In the end, the researchers found that material from the bottom of Enceladus’ would take several centuries to reach a plausible depth to be discharged by the plumes.
