So if I run my four miles with a watch on my wrist and left behind a watch sitting in a chair outside for example,.then when I return from my run then the watch in the chair would have beat the time on my wrist?

@@carlogambino8109 absolutely correct. Only the difference would be so small you wouldn’t be able to see it on your watch. But use an atom-clock and in stead of running 4 mikes take a plane-flight for a couple of hours and you’ll see the difference.

Yes, but the difference is so small and both watches so inaccurate, that you wouldn't be able to tell. If, however, you can run at very close to the speed of light, the difference will be much more noticeable.

A moving clock shows that time slows down. So if that clock was moving fast enough then time would possibly or eventually stop. In that place of no time, we would have the realm, or dimension of infinity, no beginning and no end. Thats a bit of a mind blowing thought. No time means no beginning and no end. ummm interesting :)

There are only two ways to stop time. Through speed or through gravity. That's called time diltaion. But that doesn't mean that time stops for everyone and everything. That means tine only stops for u, because you are traveling at light speed or because you are inside a blackhole. But time still passes away for everybody else. That's why time is relative. So there would be a beginnig and an end, but not for you.

The argument of the ping pong ball bouncing on the table in a moving train doesn’t seem to me to demolish the concept of absolute space. This is because it’s merely a demonstration of how things are perceived differently by observers in different positions, simply as a function of their different perspectives. Their different viewpoints in no way invalidate the physical reality that the larger perspective trumps the smaller and the smaller perspective only works within the context of the larger. To suggest that the phenomenon that is merely a function of the limited perspective of observers in different viewpoints somehow changes the physical nature of space is a confusion of categories. One is about perception, while the other is about the actual shape of the physical universe regardless of how it’s observed.

Hmm The question I have is if particles in a 3 dimensional plane can affect particles nearby on a 2 dimensional plane, then can't particles in a 4th dimensional space affect the particles in our 3 dimensional space? Could the measurment of dark matter actually be the measurment of how the 4th dimension is affecting our own?

My first question, whenever I see that model of the universe and they tell us how much time elapsed when the universe first started expanding, is “Since time is relative to the observer, how can you give such time values (especially when they talk in very small fractions of a second.”). Where is the clock located when you say how long the dark ages lasted, for instance? Especially when it is espoused that time slows down drastically when entering a black hole.

@knowledgerules2813 2 ай бұрын

Don’t tell me you believe the dark ages are moving relative to us here and now. Think again about perspective and relativity.

@skeller61 2 ай бұрын

@@knowledgerules2813 I simply asked the question, since science lecturers frequently state what happened in the first fractions of a second after the Big Bang. What reference are they using for those time references, since we learned from Einstein that space and time are relative. I don’t believe the question has anything to do with the dark ages. I’m just wondering the observer’s position that would yield these extremely short time periods of such rapid expansion.

@@stonecoldfloors8200 I understand the concept of time being relative to the observer, my question is, when scientists give presentations, they often talk about what happened in the first tiny fraction of a second after the “big bang”, , from what perspective are you witnessing that these events took place in this (extremely short) amount of time? We cannot be talking about “earth time”, since we can’t observe that time (at least now).

Thank you. Question: Why is the universe shown always as unidirectional after the " Big Bang", instead as omni directional?

@gerhardusvanderpoll 7 ай бұрын

Well to make it look omnidirectional you will have to be placed at the centre of the model which shows you a panoramic omnidirectional perspective.....but everybody else will not be at your vantage point to see the omnidirectionality which presents itself relative to your position...therefore,for the presenter to give/present everybody watching the presentation an omnidirectional view,he would have to provide each viewer with his own unique omnidirectional view relative to each one's relative perspective and position...which is impossible for him to do,due to the very nature of the concept and meaning of relativity......

Maybe its just that the obvious is only obvious from how we see the universe. From your linear Space/Time experience, the perspective, that you have created with the experience of linear Space/Time you can create the idea that something comes before, then next, then after. This is an illusion. Your higher, open mind, experiences all your moments, all your lives at once. This means you can connect with other lives and other experiences because they all exist NOW. Only in NOW can you understand how life works. Einstein's theory of Space/Time, his mathematics is fantastic, GPS and everything else is based on it. But it has it limits and it all collapses at 10 to the minus of 33cm and 10 to the minus 43 seconds. Reality is way more complex and way more exciting than present scientists understand.

It is NOT curvature of space. It’s also NOT curvature of “space and time”. The curvature is in SPACETIME. You just quoted Minkowski, how that’s the only thing now, so don’t get it wrong. It’s your metric, your coordinate system, that’s curved. Not space. Also, spacetime does not stretch, shrink and change. It’s static. It is what it always is around a certain mass or mass distribution. It follows the inverse square law and never ever deviates. Space changes. Time changes. Spacetime does not.

Here's the quote from Brief History of Time that you should focus on, it is on page one '...Time, whatever that is...' Hawkin admits to not knowing what Time actually is. How do you build hypothesis on such dodgy foundations? The word Time and the word Space are both homonyms i.e. they both have more than one core meaning. If you can't /don't describe the different meanings, you literally don't know what you are talking about. Space references spatial position (hence xyz-axis), Time references change (and change is reference frame e.g. quantum specific). Hence Spacetime references changing spatial position aka (relative) motion. You think Time and Space are fundamental. They are not. Spatial position refers existence, mass, and change refers energy differential. Energy differential is fundamentally what 'is' everything. You're welcome.

Many phisicists do not consider time as a dimension or physical quantity like x,y,z space dimensions. It is an invention so they can solve the equations. So time does not exist. Even in linear algebra there is no time.

@danielpaulson8838 5 ай бұрын

Time is required for the movement through space. The universe is expanding which means it is always moving as are we. As that happens, time emerges as a by-product. We cannot travel through space without time emerging to do it. Time and space are certainly fundamental and we experience them both through simple observation.
