Jim B is on track. Einstein got that all wrong thats why time travel has not been achieved. I don't think you can vary the imaginary. Its nothing to do with clocks.

I had asked people to define time

Time it seems is easier to measure than to define and comprehend.

I cant say that time doesnt exist or that it exits

Both would be equally true and untrue.

Time is natures way of making sure that all things dont happen at once.

Maybe Time is imaginary and we are just following conventions when we speak of time

Or maybe time does exist ;

However we need to use some quantity to chronologically mark events in this universe and so time was invented.

However , for a scientist time is very real , and time is just another dimension which is bounded and always flows forward.

I wouldn't say that time is exactly "imaginary," but it's definitely not a natural feature of the universe. Instead, time is a concept we humans use to separate events. Einstein understood this and showed that the human concept of time is relative. A kind of time travel is possible, but only when the passage of observed time (..like with clocks) is compared between two or more observers moving at different velocities. For instance, if you go zipping off into space at a speed close to light speed and I stay behind on Earth and could somehow watch a clock on your spaceship, your clock would appear to be running slower than mine. Here's the important point though--if you could somehow look back and watch my clock, it would seem to be running faster. So, who's clock is right? They both are because time is relative, meaning that there's no Cosmic Master Clock with which all clocks should be synchronized.

Incidentally, the biological aging of you zipping away from Earth or of me staying behind does NOT change. In your rocket ship you age at exactly the same rate as you would had you stayed on Earth. Same thing for me. The difference in aging ONLY appears to occur relative to each observer, you and me.

I would say that Einstein had it down pretty good. Einstein even found time travel. He understood you can go forward in time but not backwards. You can time travel forwards in time at varying speeds. The faster you move the slower time moves for you. So the faster you are moving the faster forward in time you are traveling.

As long as you do not move you are lagging in time while everyone else is moving forward in time. They will live 100 years in their life time and they would live 110 compared to your time.

Light from far out in space that we now see, happened a million years ago but it is moving so fast that it is still happening but being it is moving at the speed of light it has moved forward in time to our time.

Fun stuff to think about huh?

As far as an Imaginary it is not. But it can be changed just like the current of water or by putting a post in a stream. The water slows in front of the post but moves a little faster around and after the post and moves on with a time distortion. Meaning the water before the post stopped and the rest of the water passes on by and moved forward. Just like time for you would if you were to stop moving. Time would pass you by faster, but would be at the same pace for everyone else who would be alive way after you was dead and gone.

Time is not constant.

One minute for a drowning man is longer than an hour with your sweetheart in your arms.

A woman takes half an hour to get ready to go out. In that time a man can watch a 90 minute soccer game.

Einstein understood women though - give me 10 points and I'll explain.

Time and space are intrinsically connected. Einstein understood this probably more than anyone that had been on the Earth before him. He saw the relationships that existed between time and space, and revolutionized physics. Time is indeed real.

Time Is Money

Money Is Real

Therefore Time Is Real

(leave Einstein alone)


Elementary particles DO time travel on a daily basis in the particle accelerators around the world.

Cosmic particles too can time travel. Charged pions (a meson type particle carriers or strong interaction) that are born in the upper atmosphere and live about 10^(-8) sec could not have reached the earth surface(where its decay was detected) if it was not for TIME TRAVEL.

No time is not imaginery. Time is the only constant in the universe.

However time is is also nothing but what we want it to be. Seconds, minutes, hours, days, weeks etc.

If we wanted we could extend a second by triple, so you have 180second minutes, or make a week last 11days.

We have used the orbit of the earth to determine our measurement of time as it was/is the only ongoing constant reference we had.

Who said Einstein couldn't understand time? I doubt he could have theorized the things he did without a very thorough understanding of time.

Given that, the answer to your question is: No.

The sun effects the earth Thur the vacuum of space. The vacuum is nothing. Nothing changes. The rate nothing changes at is the measurement of time, the fact nothing changes is time.

Time is a human concept of a physical phenomenon. if it didnt exist then how would someone explain changes in time due to gravity and speed. For example if you have two watches with the same time and you put one in a plane for a long time, their times will not match up like they used to.
