QUERIES SOLVED:

1. IS SPEED AN ABSOLUTE OR RELATIVE QUANTITY?

2. HOW FAST ARE WE ACTUALLY MOVING RIGHT NOW?

3. HOW FAST IS THE UNIVERSE, GALAXIES, CLUSTERS ARE MOVING?

4. IS STATE OF MOTION OR REST ABSOLUTE OR RELATIVE?

5. WHY AND HOW SOME MOTION ARE RELATIVE WHILE OTHERS ARE ABSOLUTE?

Okay, if anyone asks you a question like: "How fast are you moving right now?" .Your first enticing answer might be, "I'm not moving forward." Upon further reflection, you find that perhaps the speed of the Earth matters. So, your other enticing answer might be, "19 miles / second around the Sun." But then you remember learning that the Sun revolves around the center of the Milky Way galaxy, and moves within the local cluster of Milky Way galaxies, and the local cluster moves within the Virgo cluster, and the Virgo cluster moves ... Now, you may realize that is not an easy question.

When mission control tells astronauts how fast they are going, there is always a valid standard of comfort. At the beginning of the journey, speed is given relative to the launchpad. But later, when the launchpad is a more dry location below the spinning surface of the Earth, the motion is given relative to the Earth's ideal, non-spinning pinpoint center. On their way to the moon, Apollo astronauts had a hard time answering the question, "How fast are you moving?" Speed ​​from Earth was one thing, and speed toward the Moon was quite another. This is because the Earth and the Moon move relative to each other. Is speed a relative quantity? Oh yes of course! Speed ​​is a relative quantity. When you say you are moving or you are resting, you must have taken a frame of reference for that. This is simply because: 

the motion or rest condition of an object is not absolute, but it is actually relative.

Galileo seems to have been the first to realize that there is no such thing as absolute motion. Speed ​​is relative. This means that motions have meaning only when they are referenced in the reference frame. Perhaps this reference frame remains. But then we have to ask again, "What relative to the rest?" Because the concept of comfort also has lost any sign of absolute meaning. Speed ​​is relative, and the rest is relative. The speed of the Earth is 19 miles / second from the Sun. The speed of the enterprise is tana 7 relative to the center of the Milky Way galaxy. Your speed is zero relative to your chair. But depending on where you sit, it is hundreds of miles / hour relative to the center of the Earth. When we pluck an eyebrow (a line deep into the skin here on a person's forehead) and ask, "But how fast is the earth moving?" We visualize the spacecraft Earth through the sea of ​​space as it orbits the Sun. But space is not an ocean. It has no substance as does water. Space is nothing. You can move between two points in space, say between Earth and Mars, but you cannot go into space. There is nothing to move from there. It is tried to say how much weight the hole carries. The weight of a hole is actually nothing because a hole is nothing. It is a void, and therefore space. Moving forward relative to anything is meaningless.

The concepts of motion and the rest have only relative meaning. They are absolutely meaningless. They only mean something with an arbitrarily chosen, artificial frame of reference. If, someday, you are stuck in your spacecraft, and you look from the side window, say, a space station that is moving at a constant speed, then there is no way to know which one you actually Heading in the direction. Neither are you really moving because there is no deeper reality about constant motion. Constant motion in a straight line has only relative meaning, a kind of relative reality. Does this mean that all speeds are relative? No! Some motions have only relative meaning, but some motions have absolute meaning, absolutely real. For example, the constant speed is relative, but the change in speed is absolute. To call something absolute in science means that arbitrary standards are not used in its measurement. It is clearly measurable. When your spaceship fires its engine, your change in speed is beyond doubt. You feel it in your stomach, and your ship's sensors can measure it. Outside your window, a passing space station may seem to change speed, but the creatures inside the station won't feel it. And no sensor can measure it. You're really changing the pace, and they really aren't. There is something absolutely real about the change in speed. The same goes for walking. If your spaceship is rotating, you can feel it, and your ship's sensors can measure it. The space station outside may seem to be moving around you, but it is you who feel uncomfortable, not the people at the space station. You're really spinning, and they really aren't. There is something real about rotation. So, some speeds are relative, and some are not. There is no deep reality about constant motion, but the change in speed is real deep, and so are rotations. We must be thoughtful in the analysis of our everyday experience in order to discover what is real in depth. Thanks for reading that's all for now.
