Quote from: Thebox on 24/01/2016 15:41:21,'' things are different now from what they were''what they were is a memory of now of what they were. You'll have to forgive me Mr. Box, something tells me we're not speaking the same language because that last sentence makes absolutely no sense to me. Nevertheless, I do have a couple things to say about time that you may find interesting. Let's preform a thought experiment................An astronaut is on a space craft traveling at c, I realize that's impossible but please just bare with me. He starts his trip just after the big bang and travels along with the expanding universe to some point in the far future where some theories suggests that a heat death has just finished it's epoch end. For the traveler in the ship, he realizes no passage of time, one moment the big bang has taken place and the next, everything has come to a very cold end. For him, there has been no passage of time. His past, present, and future are all rolled up into a very brief instant. This is a result of his velocity and the time dilation that's involved with that frame of reference. Within this same universe, we provide a fictional character that was born at the moment the big bang commenced and has lived until that same hypothetical heat death also occurs. We now arrange to have both men meet and ask them to tell us of their experiences. The astronaut will exclaim; "I just got here, I have no story to tell." On the other hand, our very long lived fictional man will exclaim; "Boy!! you sure have missed at lot of things."Time dilation is a fact my friend, if you continue to seek to eliminate it from your scientific model, you're going to experience a great deal of grief when discussing this phenomenon with other members of this forum. Take my advice and consider that when everyone else understands things a little different than you do, it is very likely that you may be in error.Whether you're in error or not, it has become very clear to me that no one here has yet been able to understand precisely what you're trying to explain and that includes myself as well.I gave it a try Mr. Box but I think we're spinning our wheels here. Sorry,... but I'm ready to move on. Please don't take offense my friend, let's just agree to disagree...........................

Like minds attract. Nothing strange about that.

Was that a lame attempt at insult or a failed effort to impress us?Well I certainly wasn't trying to impress anybody.What I was saying is that TheBox seems to enjoy spewing ridiculous sentences with garbled terminology that 'sounds good' in order to come across to the layman as an expert in the field. He is not a genius or an expert. If what he says was logical and made sense, I would not have a problem with him. However, he spams these Cambridge-based forums like nobody's business and always has an opinion no matter how incorrect or self-serving towards his own ideas. I remember a while ago he said he was going to make his last post, but here he is so clearly that was just a bid for attention/validation.No matter how many times we tell him he is barking up the wrong tree with something he insists that he is right and everybody else is wrong. It's clearly some kind of superiority/ inability to to adapt to new ideas. Everything that a scientist should not be.
Google: Is the speed of light in a vacuum invariant? You will see several choices but the top choice 'Is The Speed of Light Everywhere the Same? - Ucr' is interesting. Now .. enter Does a photon have mass? Choose 'What is the mass of a photon? - Ucr'Iff a photon has mass, which it is said to have, it will be affected by gravity, however slightly .. so it's speed will vary in a vacuum.

Choose 'What is the mass of a photon? - Ucr'Iff a photon has mass, which it is said to have, it will be affected by gravity, however slightly .. so it's speed will vary in a vacuum.As I understand it a photon is considered to have 0 rest mass. However, it does have momentum (p=mv) and anything with momentum will be affected by gravity. The complication is that no matter what gravity field you are in you will measure the speed of light to be the same, but someone else in a different gravity field will measure the speed of light at your location to be different. One way of looking at this is that gravity distorts spacetime and so the coordinates you are using for measurement are not the same as those used by the other person.
I would like to apologize for my previous comments. They were mean and unnecessary.
gravity distorts spacetime or space-time distorts gravity?

I was trying to simplify everything to basics but as soon as I pressed post I realised what I had said gave the wrong impression, but had to log off to go to a meeting.No, spacetime doesn't distort gravity either. Either mass, or something connected to mass, causes spacetime to change in the vicinity of the mass. We experience that change as gravity and it affects the way we measure time in the gravity field.Well spotted.

I have posted these posts separate to keep them separate.Imagine two batteries in the same inertial reference frame, however these batteries are special batteries and can absorb photons to self charge, however the batteries also emit a positive charge at an equal rate to absorbing. these batteries are held firmly together by their negativeness super -super glue which is also between them and the ground. now the only way these batteries can break the super-super glue is if they emitted more positive than the grounds positive pushing them apart, however the ground also steals the positive from the batteries making this near impossible. so anyway if we was to stretch to the super-super glue, there is less positive output from the batteries being pulled into the ground, so the output has less force being applied on it slowing the output suction down. in simple terms motion makes less suction, the more you move away the less output of suction. added- a bit like trying to suck the ocean up through a short straw , the straw has no effect on the ocean floor, you will not suck up sand.
