Time Does Not Exist - a thought experiment

How do we know that time exists?

We use instruments like pendulums, gears, or changes of planets or atomic rays to measure it.

Can time be perceived or measured if nothing is changing?

Imagine you are floating in outer space. You don't need air or food or water or anything like that, you are just floating. You are not a body anymore, just pure perception.

All the lights you see are very far away and don't seem to move.

Does time exist? . . . . Or is it just irrelevant?

How can you tell?

How can you measure it?

How many minutes or days or years or centuries have you been floating in space?

We are told that time can only move forward. But what would time moving backwards look like? Would people walk backwards? Would clock hands move counterclockwise? Would the sun set in the east? Would we grow young again? Or could time start running backwards and we wouldn't even know it because nothing is different?

What is "time" like inside a nebula or the sun? Is it the same as on earth or outer space?

It's absurd to think of time running backwards, but just as absurd to think of it moving forwards, or standing still. Humans have assigned a causal role to time that it does not have. Time is only the measuring stick of change. It can only measure.

How absurd would it be to say that a yardstick could cause or change/influence distance? Or a scale could cause or influence gravity. Can time running backwards make you walk backwards or grow younger? Of course not, so how could it make you walk forwards or grow older? It can't. It can only measure the rates of those things.

Time is merely a human construct that measures rates of changes of things relative to one another.

There is only "now." Time does not exist.

What would happen if physics would remove time from math equations? Or redefine it to it's proper role as only a measurement of change rather than treating it as a real entity?

On Time Travel

I'll quote Tom Van Flandern and William Lyne on the impossibility of time travel:
"... time travel must also involve travel through space. For example, the Earth is continuously traveling through space in its orbit around the Sun, in the Sun's orbit around the Galaxy ... If one could suddenly pop into the universe at a past time, how could one expect to find the Earth in space at that time? Time travel is therefore disallowed by the principles of physics."--Tom Van Flandern, Physics has its principles.

"Our earth moves around the sun, while our solar system moves around our galaxy, which in turn moves around the edge of the Milky Way, which in turn moves around the outer reaches of the Magellanic Clouds. Our earth and everything on it, and everything else in the universe, can never be in the exact same place ever again. Any rational person should be able to see why "time travel" is a physical and metaphysical impossibility."
--William Lyne, Pentagon Aliens, 3rd ed., 1999, p. 274.


We were taught in grade school that the earth and planets revolve around the sun in flat, mostly circular orbits. But that is a great oversimplification. In reality, our solar system also rotates with the Milky Way Galaxy, so the real situation is a spiral type movement.

And of course the Milky Way Galaxy is not only rotating, but also moving through the universe.

Imagine all these galaxies rotating and moving through space ...

Everything in the universe is constantly moving.

What would happen if you could stop ... say an atom or electron from moving?????
