Why doesn’t gravity eventually lead to a universal “Big Crunch” event? According to the laws of gravity, the more matter there is in the universe, the more it should attract, eventually leading to a collapse. However, this is different from what we observe in the universe. Instead, the expansion accelerates, indicating something else must be at play.
Pluto’s fascinating history began with its discovery by American astronomer Clyde Tombaugh in 1930. Tombaugh was conducting research at the Lowell Observatory in Arizona when he identified a small object beyond the orbit of Neptune that seemed to be moving against the background of stars. Through further observations, he determined that this object was a previously undiscovered planet, which he called Pluto, like the Roman god of the underworld.
Entanglement is a phenomenon of quantum mechanics that has fascinated scientists since its discovery. When two particles are entangled, they become linked so that their properties are correlated, regardless of the distance between them. In other words, if we measure a property of one of the entangled particles, we can predict the measurement of the other particle with absolute certainty.
Most people have heard the expression, “this is not rocket science.” The phrase’s origin dates back to the mid-20th century when the United States was experiencing a surge in rocketry research and development, particularly as part of its space program. It is often used to convey that a task or concept is not difficult to comprehend, and it has become a common phrase in everyday language.
The question at hand pertains to whether or not their intelligent life exists beyond the confines of our Earth. The scientific community has grappled with this enigma for centuries, attempting to ascertain whether we are alone in the universe or whether other intelligent beings exist. Historically, this question has been approached in various ways, ranging from the simple analysis of observations to more elaborate theoretical conjectures.
