Does time have a beginning?

[James_S_Saint]

And? Are you denying that report provides supporting evidence for the theory that mass warps spacetime???

I should have said mass before, but i am tired.

I am denying that mass “warps” space. It does have effect on time because time, unlike space, is a rate of change and thus is relative to movement. Radiation slows in the presence of a mass field, but space does not change. Rather objects and movement (objects are made of movement) bend due to one part of their makeup slowing down more than another (the inner, closer to the source of the field, slows more).

As usual online, you presume that your naive perspective is all-encompassing and that you actually understood what was being told to you. Unlike you, my “opinions” are not mere hand-me-downs.

 

[James_S_Saint]

Ok let me put it to you this way, you are moving through space (the direction is irrelevant) and i pause time. Do you stop moving? Now i reverse time, what direction are you now moving?

Physical time has no reverse direction to it. You **CANNOT **stop it, and certainly cannot reverse it. Those are merely mental concepts.

 

[sidbrown]

I really don’t see what is so hard to grasp. Up, down, left and right are relative to the object.

Ok let me put it to you this way, you are moving through space (the direction is irrelevant) and i pause time. Do you stop moving? Now i reverse time, what direction are you now moving?

The point which you are missing is that you cannot reverse time.
I say that what you claim here is impossible:

Now i reverse time, …

No one has ever succeeded in reversing time, regardless of your claim that you have done it. Your claim here that you have reversed time is unfounded. If you can reverse time then you will be a very famous scientist and a rich man as well. For example, you have the knowledge today that horse A has won the race at the race track. You then reverse time, as you claim you have done, and go back and place a one million dollar bet on the race. You then win twenty million dollars and move forward in time as a wealthy man. It just cannot be done.
Your claim that you have reversed time is truly preposterous. It is the stuff of science fiction, not reality.
Time has one and only one direction and that is forward.

Oh catty catty ahaha .

Right so you deny general relativity. Fair enough, you will understand when i don’t as i am not a physicist and it seem to me that that relativity is widely accepted by my physicist counterparts. You may well have been more effective linking some peer reviewed papers for me to read that support your claim, instead of the school boy remarks.

Oh and “hand-me-downs” are the basis of knowledge. Tell me how much knowledge have you gained on your own, hmm let me guess… NONE?

What on earth are you talking about when have i ever said i can reverse time???

I said according to the theory of relativity space and time are in fact one, which we call spacetime.

Your mistake is that you think that you understood what it said.

General relativity never really said that space bends. That was just an attempt to explain the appearance of the effect. The theory never claimed that. The theory merely stated that all of your measurements will be related [because you measured everything relative to something else]. From that idea, a person can say, “well if I change the mass, then this space variable will change, therefore space changes”. When in fact, all it was saying is that your spatial measurements will be different - IF you take them from outside the system.

And your guess is very wrong. I am one of the genuine articles, not merely someone spouting what others before me have said.

Are you saying that in relitivity space and time are not unified as spacetime???

The truth is that general relativity and quantum field theory are not compatible and in fact the attempt to unify the two and form a coherent and consistent theory of quantum gravity has run into problems since general relativity models gravity as a curvature within spacetime, whereas quantum field theory depends on fields in the flat spacetime of special relattivity. Loop quantum gravity or spin foam theory will not work because they are not Lorentz invariant, and the main candidate right now is the string theory or M-thoery which is highly mathematical and not accepted by a few physicists today.

I fail to see how that is relevant.

In the theory, space and time are both considered as dimensions in a mathematical array. That conceptual array is called “the space-time array”. It has very little to do with actual physical existence. It is a mathematical model from which equations can be made and used.

They could have used radial spatial dimensions rather than Cartesian and every theory would look different. It is just a mental model. It is not reality itself.

 

[sidbrown]

You deny that you wrote post #40?
Who wrote it?

I really don’t see what is so hard to grasp. Up, down, left and right are relative to the object.

Ok let me put it to you this way, you are moving through space (the direction is irrelevant) and i pause time. Do you stop moving? Now i reverse time, what direction are you now moving?

I will point out the phrase right here:

Now i reverse time, what direction are you now moving?

The fact is that you cannot reverse time.
You are wrong, and your claim that you have reversed time is preposterous.

Please point me to Einstien’s research that supports the above, for i can’t find anything but that which links space and time into a single dimension… spacetime.

You have to be trolling? At least i hope you are. I was speaking, what we call… hypothetically.

 

[sidbrown]

You have to be trolling? At least i hope you are. I was speaking, what we call… hypothetically.

This cannot be a hypothesis which is supportable. If you are going to have an inertail frame of reference in which you move backwards in time, this would entail the movement of information faster than the speed of light, which is a violation of special relativity. If you aare going to assume traversable wormholes, even then you are not really moving backwards in time.
Your claim of reversing time is unsupportable, even as a hypothesis.And as well it presents serious philosophical problems.
Also, why don’t you just stick to the question at hand instead of engaging in personal attacks?

 

[sidbrown]

I fail to see how that is relevant.

It is relevant because it touches upone the question of whether or not general relativity is the last word, which is cannot be becasue there is a problem with the consistency with quantum field theory.

 

[AlbertBall]

And your guess is very wrong. I am one of the genuine articles, not merely someone spouting what others before me have said.

Oh i missed this wee piece of gold. Ok tell me one piece of knowledge you have gained by your own accord. Your arrogance amazes me.

Oh and like i said i am not a physicist, my inital degree is in maths and computing. I am currently carrying out research on the impact of 3D environments on students cognitive and learning styles, oh and guess what what ever knowledge i do personally produce will go on top of the MOUNTAIN of knowledge i have gained from others, and further more i could not hope to produce anything without the knowledge i have gained from OTHERS!

But not you eh, you didn’t go to school, you were self taught starting out with a twig and a rock??

I didn’t you claimed i said i could make time go backward. I never made such a claim, that is there for all to see.

Again i never said it is. I said space and time are linked. I have yet to be presented with anything that says otherwise.

 

[James_S_Saint]

Yours does me as well. You only know what others have told you (whom you decided to respect enough to listen) and you do not really understand what they said, yet you expect for me to impress you with a claim of something that you haven’t already heard from one of your masters? - No thanks. If you cannot use logic, which is all I ask of you, then I expect no agreement with anything except what you have been programmed to believe (even though what you heard wasn’t their intention).

I have yet to be presented with anything that says otherwise.

Impressing you isn’t our job. It is your job to listen and ask for clarification. And accept it when given. But it takes a little humble thinking to do that.

 

[sidbrown]

Again i never said it is. I said space and time are linked. I have yet to be presented with anything that says otherwise.

It is universally recognized that time has an arrow of direction. Proof of this is provided by the Second Law of Thermodynamics according to which entropy, or the measure of disorder, tends to increase as time increases.
Let me put it to you this way:
Time is asymmetrical, since as time increases, the amount of disorder in an isolated system incresase.
Space is symmetrical.
There is in addition a causal arrow of time, The causal event always occurs before the event it effects. For example, conception always comes before birth.
So time and space are different. One is asymmetrical, the other is not.
In post #40, you wrote something about reversing time. I submit my opinion to you that this is impossible, whether it be a claim or a hypothesis or whatever, and this is proven conclusivley by the second law of thermodynamics and by the principle of causality and as well by our psychological intuition that time flows in one direction only and cannot be reversed.
