The grandfather paradox is a theoretical, logical puzzle regarding time travel, not a physically observed, real-world event. It posits that if you travel back in time and kill your grandfather before your parent is born, you would never exist to travel back, creating a contradiction. While often used to argue that time travel to the past is impossible, it is also a popular sci-fi concept.
CTCs suggest that if spacetime is warped in specific ways—such as near a rotating black hole—time travel to the past could be possible. If an object could follow a CTC, it might experience time in a closed loop, enabling it to influence past events and potentially creating paradoxes like the Grandfather Paradox.
Physicist claims to have solved the infamous 'grandfather paradox,' making time travel (theoretically) possible. The grandfather paradox is just one of the thorny logical problems that arise with the concept of time travel. But one physicist says he has resolved them.
Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.
In logic, many paradoxes exist that are invalid arguments, yet are nevertheless valuable in promoting critical thinking, while other paradoxes have revealed errors in definitions that were assumed to be rigorous, and have caused axioms of mathematics and logic to be re-examined.
Jesus, as the icon of Christ consciousness (1 Corinthians 2:16), is the very template of total paradox: human yet divine, heavenly yet earthly, physical yet spiritual, a male body yet a female soul, killed yet alive, powerless yet powerful, victim yet victor, failure yet redeemer, marginalized yet central, singular yet ...

There are many questions about traveling to the past that do not yet have solid answers in science. However, in all time travel theories that seem to be allowed by real science, there is no way a traveler can go back in time to before the time machine was built.
Quantum physics does not “prove” the Christian faith, but it does challenge the materialist assumptions that have long dominated scientific and philosophical discourse. It invites us to see the world not as a machine but as a creation: mysterious, beautiful, and reflecting the presence and love of God.
Albert Einstein's theory of time travel is built around each of his theories of relativity. It is that an object moving at the speed of light will be able to travel into the future. This theory implies that only time travel into the future is possible.
On our current understanding of the Universe, we could potentially travel into the future, but travelling into the past may well be a total no-no. The only remaining loophole is that the theories this is based on are incomplete.
While we can see the way Andromeda looked 2 million years “ago” its current state is simply a prediction of what we will see 2 million years from now. It has no real meaning. To drive this point home, consider that there are galaxies in the universe right now that are moving away from us faster than the speed of light.
In Interstellar, Miller's planet orbits close to the black hole Gargantua, where gravity is so strong that time runs much slower. This is gravitational time dilation, a prediction of Einstein's relativity. On the planet, one hour equals about seven years outside.
Time travel to the future is possible, but time travel to the past is impossible. All laws of physics in the Universe prevent us from time traveling to the past.
NASA's "Hand of God" refers to a pulsar wind nebula (MSH 15-52) that looks like a giant hand reaching out, formed by the remains of a massive star's supernova explosion, specifically centered around the neutron star pulsar PSR B1509-58, which emits energetic particles that glow in X-rays, creating the hand-like structure. The name comes from its resemblance to Michelangelo's depiction of God's hand, with detailed images captured by telescopes like Chandra and NuSTAR revealing intricate details like fingers and a wrist.
Sergei Krikalev, a Soviet cosmonaut, was stranded in space for 311 days (nearly a year) after the Soviet Union collapsed in 1991, leaving him without a country to fund his return and forcing him to stay on the Mir space station until the new Russian government could arrange his rescue, famously earning him the nickname "the last Soviet citizen".
Reportedly equipped with an IQ of 145, Grissom was nevertheless, he later admitted, not much of a "whiz" in school. "I guess it was a case of drifting and not knowing what I wanted to make of myself," he said.
Neil Armstrong was the first person to walk on the Moon, stepping onto the lunar surface on July 20, 1969, during the Apollo 11 mission, followed shortly by Buzz Aldrin, who became the second person to walk on the Moon. Armstrong's famous words upon stepping out were, "That's one small step for man, one giant leap for mankind".
The 30% rule in AI is a guideline suggesting that AI should handle roughly 70% of repetitive tasks, while humans focus on the remaining 30% requiring judgment, creativity, and ethics, or conversely, that AI's contribution to creative work should be limited to about 30% to maintain human oversight. It promotes AI as a supportive tool, not a replacement, ensuring humans remain in control and develop critical skills, especially in education and professional settings, by balancing automation with human insight.
Daisy is, of course, not a real grandmother but an AI bot created by computer scientists to combat fraud. Her task is simply to waste the time of the people who are trying to scam her.
