★ Humanity's longest-standing companion, the "Moon," is actually leaving us
The Moon moves away from the Earth at a rate of four centimeters per year. When the Moon first formed 4.6 billion years ago, the distance between the Moon and the Earth was 22,530 kilometers, but now the average distance between them is 384,400 kilometers. One day in the future, the concept of a month will change: it will no longer be 30 or 31 days, but 47 days.
★ Can "Wormholes" allow instantaneous teleportation?
If you've seen the movie "Interstellar," you must be impressed by the scene where the protagonists pass through a wormhole to reach other planets outside the solar system. According to theory, this method of instantaneous matter transfer is indeed feasible, but so far, no such "bridge" has been discovered...
★ Are you wishing on a shooting star or space junk?
Wake up! The "object" you are wishing on is just dust or fragments, or even space junk! When these substances are attracted by Earth's gravity and fall into the atmosphere, they burn due to intense friction, forming the beautiful meteors seen by humans.
★ Is the universe infinite?
Many people believe the universe has no boundaries, but Olbers' Paradox refutes this view: if you stand in an infinite forest, no matter which direction you look, you can only see tree trunks and no gaps.
By the same token, if the universe were infinite, then light from all stars would reach Earth and merge into one sheet. Since there are actually dark gaps between stars, it means the universe is finite. Through these gaps, what humans see is a dark wall surrounding the universe...
★ Earthlings once sent a record to aliens!
Is there other life in the universe? To greet unknown other beings living in the universe, humans actually launched a gold-plated copper record that can be preserved for a billion years into outer space. The record contains ninety minutes of the "Sounds of Earth," which is our greeting gift to aliens...
