π In the movie Interstellar, time shifts differently in space, resulting in a significant time difference for the protagonist when he returns to Earth.
βοΈ The Twin paradox, a thought experiment by physicists, involves one twin traveling at near-light speed, causing time to slow down relative to the other twin on Earth.
β° Time dilation occurs not only due to speed, but also due to gravity. Large mass objects can cause time to slow down around them.
π Newton's famous story of the falling apple led to his formulation of gravity.
βοΈ Newton's theory of gravity states that the force of attraction between objects depends on their mass and distance.
π In a vacuum, all objects fall with the same acceleration, regardless of their weight.
π The phenomenon of objects falling at the same rate is not fully explained by Newton's theory of gravity.
π An alternative explanation proposes that objects do not actually fall, but rather the Earth moves upwards.
π Gravity is not a force but the result of the curvature of spacetime.
π°οΈ In a zero-gravity environment, objects experience weightlessness.
β¬οΈ Acceleration can create the same sensation as gravity.
π We actually live in a 4-dimensional spacetime with time as the fourth dimension.
β³ All events in spacetime are interconnected and should be viewed as a continuum, similar to frames in a film.
βοΈ The presence of mass or energy causes spacetime to curve, influencing the motion of objects.
π Einstein's prediction of the bending of starlight during a solar eclipse was proven true in 1919.
β±οΈ Einstein's theory of general relativity is more complex than just gravity and encompasses the entire universe in the context of spacetime.
π³οΈ Black holes, initially a mathematical hypothesis, are now believed to exist in the universe due to the curvature of spacetime caused by their immense mass.
π The visual representation of a black hole in the movie 'Interstellar' is based on Einstein's gravitational equations.
π‘ In 2019, scientists were able to capture the first image of a black hole by combining telescopes worldwide.
β±οΈ The curvature of spacetime caused by gravitational effects leads to time dilation, with clocks closer to a black hole running slower than those further away.
β° The theory of general relativity explains the concept of time dilation.
π³οΈ Black holes have a massive gravitational pull that causes significant time distortion.
π Interstellar travel and its depiction of time compression is a fictional concept.
