Are you Really that Dumb…..What the FK…. DO you think Q meant by How Far is the Closet Star….You FKwits. with the Lil Green Men Bullshit …IDIOTS….Think… its across the street…..That's NOT how it Works…What the FK is Wrong with you People …..Read a .Book…..kekekek

How Far is the Closest Star?

The simple answer is that the Sun is the closest star to Earth, about 93 million miles away, but that might not answer your question. Outside of our Sun, our system's nearest neighbor is Alpha Centauri. This isn't a single star, it's actually a triple-star system — three stars bound together by gravity. Alpha Centauri A and B are two bright, closely orbiting stars with a distant, dim companion named Proxima Centauri. The inner binary appears to the unaided eye as a single star, the third brightest in the night sky, but it lies 4.37 light years from the Sun. Faint Proxima Centauri is the one that claims the honor of being our true nearest stellar neighbor at only 4.24 light years away.

It’s difficult to conceptualize such vast distances, but a popular analogy sets the Sun at the size of a grapefruit. If you wanted to get from your grapefruit-sized Sun to a grapefruit-sized Alpha Centauri system, you would have to travel about 2,500 miles, which is about the distance from coast to coast on the continental United States. And that’s just to the Sun’s closest neighbor!

Does that means it's too far for our Earthly reach? Maybe not. There's a plan in the works, funded by Breakthrough Starshot, to send tiny smartphone-size probes to the Alpha Centauri system. It would be a one-way trip that would take these lightsail-powered spacecraft 20 years. Why go such a long way? Well, for one, astronomers have found a planet orbiting Proxima Centauri. While it's unlikely it would be habitable, boy would that be a fun and informative planet to visit. (Not that it would be an easy trip.)

Gravity: We might have been getting it wrong this whole time

Symmetry has been one of the guiding principles in physicists' search for fundamental laws of nature. What does it mean that laws of nature have symmetry? It means that laws look the same before and after an operation, similar to a mirror reflection, the same but right is now left in the reflection.

Physicists have been looking for laws that explain both the microscopic world of elementary particles and the macroscopic world of the universe and the Big Bang at its beginning, expecting that such fundamental laws should have symmetry in all circumstances. However, last year, two physicists found a theoretical proof that, at the most fundamental level, nature does not respect symmetry.

How did they do it? Gravity and hologram

There are four fundamental forces in the physical world: electromagnetism, strong force, weak force, and gravity. Gravity is the only force still unexplainable at the quantum level. Its effects on big objects, such as planets or stars, are relatively easy to see, but things get complicated when one tries to understand gravity in the small world of elementary particles.

What the FK ..You people are supposed to be Researches…..STOP…Being so Gullible…PLEASE..Read A History Book..Oooooppppps sorry kekek

How the ancient Greeks proved Earth was round over 2,000 years ago

An Ancient Greek mathematician calculated the Earth's circumference without ever leaving home

In the mid-20th century, we began launching satellites into space that would help us determine the exact circumference of the Earth: 40,030 km. But over 2000 years earlier, a man in Ancient Greece came up with nearly the exact same figure using just a stick and his brain. Following is a transcript of the video.

But over 2,000 years earlier in ancient Greece, a man arrived at nearly that exact same figure by putting a stick in the ground. That man was Eratosthenes. A Greek mathematician and the head of the library at Alexandria.
