🍃The curvature of space-time, caused by massive objects, explains Mercury's orbit deviation.
🌌The Big Bang is believed to have birthed all of space-time, including the past, present, and future.
What is space-time?
—Space-time is the four-dimensional fabric where space and time are intertwined, as described by Albert Einstein's theory of relativity.
How does the block universe theory explain time?
—The block universe theory suggests that all of space-time, including the past, present, and future, already exists, challenging the concept of presentism.
What is eternalism?
—Eternalism is the idea that all of time, past, present, and future, exists in its entirety rather than just the present, as proposed by presentism.
How does space-time curvature affect planetary orbits?
—The curvature of space-time, caused by massive objects like the sun, determines the path of planetary orbits. It explains phenomena like Mercury's orbit deviation.
What is the origin of space-time?
—The Big Bang is believed to have birthed all of space-time, including the past, present, and future.
