no i mean like if i throw a ball behind a fence and then i can't see it anymore what happens to it???
Simple, it stays wherever it loses all of its kinetic energy and then sits put or gets moved around by people picking it up
well yeah but if i can't see it it must be not there anymore right??? why does it just disappear liek that
Welcome to philosophical mind ****s 101. Today we will be covering existence. Your ability to think allows you verify that you exist in some form, everything else must be observed through senses. But when something is not being observed we have no proof that it continues to exist. Sure we "know" where that book we put down is, but perhaps it's existence is reestablished once you are in a position to re-observe it. Furthermore our senses can be fooled such as with hallucinations. If something is proven to sometimes give bad data there is a risk that any data you get from it could be bad. The same applies to our senses; you cannot be 100% sure that even these words you are reading now exist anywhere outside your own head.
This ^ And Blind people still know of the ball's existence without seeing it >:3 We have no proof of what happens to it so this is where we humans use our imagination to find an answer. However, since we cannot prove this answer we are stuck asking the question. But the real question is, does it matter? If it's existence was compromised when we were in contact with it then that would create a real problem but since it will always be there when we are, why do we need to question what it does when we are not around?
Nothing ever stops moving. Take a step back from your viewpoint Right now you are on a planet with a circumference of 40,075 kilometers (at its widest) that completes one rotation every 23 hours, 56 minutes, and ~4 seconds. If you are standing on the equator, this means that you are constantly traveling at a rate of 460 meters per second (1,000 miles per hour) relative to some imaginary point at the center of the earth. Take a step further back. The circumference of Earth's orbit is ~584,336,233.5677 miles. The time is takes to complete that is ~365 days. That means that you are constantly traveling at a rate of 67,108 miles per hour (30 kilometers per second) relative to the sun. Take another, even bigger step back. The Milky Way is a spiral galaxy that rotates such that each arm moves around the center like a disc. Our solar system resides on one of those arms which travels at a rate of 515,000 miles per hour (828,000 kilometers per hour). Unrelated Fun Fact: The oldest known star in the Milky Way is no less than 13.6 billion years old, making it almost as old as the universe.
