    It's just a personal belief but I don't think that time travel is possible.

    I surely hope so. Imagine children of the future having to learn 25 alternative histories that all happened.

    I don't know where this time travel tangent arose but, while it makes for some very interesting stories, isn't really possible in my eyes.

    It comes from multiple places, including the idea that time-space warps around a black hole. Hollywood has a need for time-travel to be possible.

    In the theory, everything that has energy has mass and I tend to think of C as a universal drag coefficient. By lowering the amount of drag, particles would, in theory, lose mass and could travel faster. Even light would travel faster.

    ..which might be also a better explanation than the hyperexpansion of the early universe. If the velocity (or drag, depending on your viewpoint) can vary, then there is no longer a need for a rapid expansion.

    Yeah, same sentence quoted twice, but just wondering; how much "particles" are there in a human that has no mass?

    Yes, but I haven't come up with anything better yet :rolleyes:

    I have this written down at home but I do not have the academic credentials to get anybody in the field of physics to listen. I just tell it to people who might be interested to hear. With so little in the way of resources, I wouldn't be able to prove a word of it in a lab. It doesn't help that I'm not really very good at any mathematics above college algebra which is why I stay clear of graphics programming and security algorithm design. Sorry if some of this is academic speech as I don't know of any other way to describe it.

    Are you familiar with open source? If you can describe your ideas and distribute it (in whatever form), it will be built upon by others. You can fill up any current gaps using "fairy dust", as lots of theories are incomplete. My math-skills are at the level when I left school; junior second

    Yea, you have to be jovial while exploring lines of thought that run counter to established beliefs. If you want proof that time travel is impossible, thank history. Do you think for a second that if time travel were possible somebody would have already traveled back in time and assassinated Hitler in the trenches of France during WWI? We're human and I am certain some American would have done it just to prove that it could be done. :laugh: I also don't think that black holes exist or at least not in the way that we currently think that they do. The point is that we use math to describe the universe but it doesn't work in reverse. While Hawking is a brilliant mathematician, just because you can prove something exists on paper does not mean that it exists in reality. I find it far more probable that the phenomenon that we think are black holes are really just the dead cores of the very first stars. Since black holes where accepted in mainstream physics, some people have gone to great lengths to try and prove it and thereby preventing other avenues of thought. I see them as very large bodies of normal matter with large proportions of radioactive material. The radioactivity will keep them very hot for a long time, continuously spewing radiation into space but other then that they behave like any other celestial object. Until we get close enough to one to take real-time measurements, it is still an educated guess either way.

      I'm not sure what you mean. It's not infinitesimally small, it's zero. The equation measures rest mass. They are saying if you change the definition you can use it the other way but you've changed the definition into something that makes a mess of things, not because the equation is correct and we just don't understand it, but because if you use that definition of mass then now you have to carry the second part of the equation that you left out into EVERYTHING ELSE to make it work. And the second part of that equation is messy. There's no conspiracy here.

      I'm not calling a conspiracy. Recent discoveries have led me to a questioning of fundamentals. Take the EM Drive for instance. The experiment has repeatedly shown that the drive is creating thrust from electromagnetic energy in a vacuum but that shouldn't be possible. I really goes against convention. The EM Drive is basically saying that a vacuum is not empty and there is something there for the EM Drive to push against. Since we might have gotten the concept of what's in the space around us wrong, what else have we gotten wrong?

        Let me see if I can explain this little theory I've been mulling over in my head since back when I was taking physics at my local university. First, I will start with your statement

        Eddy Vluggen wrote:

        come up with a theory where light goes faster

        One of the central tenants of my idea is not to find examples of light deviating from it's set speed but to answer why does it always want move at that speed. What is it about the constant that makes it this way not just for light but all energy. So I started pondering the meaning of Einstein's famous equation and it's implications. e = mc2 implies that energy is a function of an interaction between mass and the constant. It implies that energy is irrelevant and only mass and C matter. Most of the widely accepted theories are rooted in this. If we switch things up, the equation takes on a whole new meaning. m = e/c2 implies that mass is a function of an interaction between energy and the constant. It implies that mass is irrelevant on only energy and C matter. More to the point, since energy is in a constant state of acceleration, the mass of a particle is a direct result of energy shedding velocity due to the C. The caveat is that if we could figure out what the universal principal is that causes all energy to shed velocity to make mass, we could figure out how to negate it, thus making faster-than-light travel possible. I may be off my marks but I've asked several physicists about this without a straight answer; even emails to NASA and FermiLab got me nowhere. The answer was always make up a mathematical model and prove it. It's the same exact model they have now just a different way of looking at it. Never did get anywhere with it so far. The only nice thing is that it offers an explanation for electron quantum jumping. I've got theories on gravity too but I can never get any help from physicists on that one either. Not even a suggestion on where to start.

        OK, let me come at this from a more philosophical angle. Which came first, energy or matter? AFAIK, current mainstream cosmology would have to say that energy came first, at least if you hold with the Big Bang Theory. You can convert energy to mass and vice-versa, but when you look closely enough matter is fundamentally a product of energy (think of what an atom truly is). So is the everyday material world even "real" then, if solid matter is merely an "illusion" created by tiny energy clusters sparsely distributed through vast quantities of empty space? Well, it's as real as real gets, from the experiential viewpoint, because there's no "more real" world that you can visit. However, that doesn't mean that matter is the foundation of reality itself, it's just the foundation of our experience of reality. But what is it that experiences this reality? There is one truly undeniable statement in philosophy, one statement that is more certainly true than anything else that can be said. It was famously stated by Descartes as "I think, therefore I am." In other words, the fact that I am able to contemplate being proves that, in fact, being is a thing and that I exist. Importantly, the only thing that we can be so certain that exists is consciousness. Consciousness is the only thing that experiences reality, and so in some sense reality is always defined in terms of consciousness (even for materialists, who have to deal with the sensory problem). You cannot, in good intellectual faith, ignore the question of consciousness if you seek an accurate understanding of reality. [I'm going to beat on Daniel Dennett a bit here because his book Consciousness Explained has become like a bible for naive materialists, so I have to deal with him in order to argue my case, because a lot of people think that the title of this book wasn't a lie.] But science ignores the question of consciousness all of the time, mainly because it's so hard. When scientists do consider it, many of them go with a tortured materialist explanation a la Daniel Dennett. But when they do so they have to wrestle with the problem of mind/body dualism (Idealism doesn't have this problem, but Dennett seems ignorant of that and considers an assault on mind/body dualism enough to dismiss all non-materialist views). More importantly, materialists have to explain how consciousness exists at all in a materialistic universe. The idea that consciousness is an emergent property of matter is mystical magical BS, the very thing that material

          The longer one practices physics, the more entrenched prevailing thought becomes. The "trap" of science is that eventually it becomes its very antithesis: a religion, one based upon perceived facts. The word "perceived" escapes notice, however, and the physicists become the acolytes of the "church" of science. Those acolytes then defend their religion to the death. Your new idea is heresy.

            I completely agree, all I'm saying is that faster than light travel doesn't make sense because speed of light travel is actually INSTANT. So, you are going to have to define what you mean by faster than light travel, because I don't know how you can get somewhere faster than instant.

              I've read up a little on the conscious angle. It's an interesting blend of physics an philosophy and I think I could attempt sum it up as "the universe exists the way I observe it because I am the one observing it that way." The point that I am trying to make with this sub-thread is that there could be some fundamental flaw in our current perception of physics but time has turned theory into doctrine and it has become nearly impossible to change direction due to the 100+ years of momentum that has built up behind it. To me, a lot more things make sense when you boil the entire universe down to three things: natural energy (the stuff that makes up particles), kinetic energy, and some still undefinable force that keeps the natural energy from existing everywhere simultaneously.

                  Yeah but....you are. You are travelling infinitely fast from your perspective. If you are travelling at the speed of light, your rocket ship can instantly arrive anywhere in the universe INSTANTLY. I think that's what you are missing about the whole relativity thing. Pick the further thing in the universe you can think of. If you get your ship up to 99.99999% the speed of light, you will literally get there in a second.

                      Allow me to clarify for a second. You see an awesome star you want to visit. You look into the night sky, and you see a supernova exploding. You want front row seats to this event, so you jump into your speed of light ship to go look at it. You get there instantly, i.e. you have aged say 1 second, but when the ship stops at its destination you will have found that the supernova is gone. But how? You got there instantly! Well that's simple...it's because the light you were looking at from Earth was 20 billion light years old, so the star actually exploded 20 billion years ago. You got there instantly, but "instantly" near the star is 20 billion years later than the light you are seeing from earth. So if you don't believe in time travel, this is the fastest you can go. If the star exploded 20 billion years ago and it's now dead, you can't get to the star as it was 20 billion years ago. You can begin your journey now at infinite speed from your perspective and see how it looks NOW, 20 years after that supernova explosion that the light just got to you from. If you have an alternate proposition, such as multiverse theory, then I'm all game, it's possible. But you can't have no time travel and faster than light travel, it just doesn't make sense. If you explain a theory of how that would work where I can picture it working then I'm all for it being possible, but as you've laid it out, it won't work.

I guess what my brain isn't getting the jump from faster than light to instantaneous travel. To me faster than light is just that, traveling faster than 300,000 km/s (I'm ignoring the limitations on speed here).

                          If you haven't done so already, you should read The Structure of Scientific Revolutions by Thomas Kuhn. It's about exactly what you're saying about science and resistance to new ideas.

                            Well then you're in luck - get up to close to the speed of light and you will get there instantly. If someone on earth is looking at you as you make your journey then it will look like you are moving at the 300,000km/s, but at that speed space in front of you is compressed so much that you get there instantly, and space behind you expands so much that 20 billion years will have passed on earth. Hence why "everything is relative" - there is no "absolute" frame of reference in the universe, everything changes in relation to everything else.

                                You too! I should correct a previous statement - I meant to say time is compressed/expanded in front/behind you not space. That's what they are talking about when they refer to "time dilation" in relativity.

                                  Yea, you have to be jovial while exploring lines of thought that run counter to established beliefs. If you want proof that time travel is impossible, thank history. Do you think for a second that if time travel were possible somebody would have already traveled back in time and assassinated Hitler in the trenches of France during WWI? We're human and I am certain some American would have done it just to prove that it could be done. :laugh: I also don't think that black holes exist or at least not in the way that we currently think that they do. The point is that we use math to describe the universe but it doesn't work in reverse. While Hawking is a brilliant mathematician, just because you can prove something exists on paper does not mean that it exists in reality. I find it far more probable that the phenomenon that we think are black holes are really just the dead cores of the very first stars. Since black holes where accepted in mainstream physics, some people have gone to great lengths to try and prove it and thereby preventing other avenues of thought. I see them as very large bodies of normal matter with large proportions of radioactive material. The radioactivity will keep them very hot for a long time, continuously spewing radiation into space but other then that they behave like any other celestial object. Until we get close enough to one to take real-time measurements, it is still an educated guess either way.

                                  The simpeler explanation is the more probably one. Doesn't sound as exciting though.

                                  In that case, I'll rather go for the romantic view that there is an entire universe inside every black hole :)

                                    Yeah but....you are. You are travelling infinitely fast from your perspective. If you are travelling at the speed of light, your rocket ship can instantly arrive anywhere in the universe INSTANTLY. I think that's what you are missing about the whole relativity thing. Pick the further thing in the universe you can think of. If you get your ship up to 99.99999% the speed of light, you will literally get there in a second.

                                    So, if you go slower than light, you travel further than light itself travels in a second? I'm going to re-read this thread later on again, I must have missed some things :thumbsup:

                                      Phase velocity can exceed the speed of light - it may be exploitable, but for sending information and not any physical objects. It all comes down to the relativistic mass of any object with mass. As it approaches the speed of light its mass approached infinity - so acceleration becomes impossible. An interesting caveat to that could be that as anything with any mass approaches c, they all approach the same mass. Which causes all sorts of conflicts, logically - and one might as well accelerate an entire planet as accelerate a grain of sand as they'll take the same effort in the end. Special relativity does bend the brain, a bit.

                                      The problem here is that you are treating infinity as a quantity, which leads to all sorts of paradoxical things. Infinity is a concept not a number, it has no quantity that can be compared to some other quantity. This is why mathematicians talk about approaching infinity rather than infinity itself as a number. Besides, before the object approached "infinite" mass, the universe would collapse around it and destroy everything anyway, because gravity. You would destroy the universe before you approached the speed of light, even leaving aside the fact that you used up most of the energy in the universe in the process.

                                        I did say approach, and besides that, these are both approaching the same order of infinities (Alephs). The universe wouldn't collapse around it - if for no other reason than that the information about it's mass would still be constrained to traveling at c. Anything else moving at 'c', therefore, may never know of the event unless it's heading more-or-less towards it. Or - if I were politically motivated I'd say: you've no experimental proof - but one doesn't present politics in the Lounge.

                                          I'm not clear on how bringing set theory into it changes things. The initial energy required for acceleration would be much greater for the planet than for the grain of sand, so that is still going to carry forward as you approach infinity, right? It would amount to the same energy in both cases if you actually reached infinity, but of course you never would. Also, I'm not clear about how that mass is going to effect (or not) the rest of the universe. Are you saying that there would be no gravitational force exerted on the surrounding universe as a near-infinite bit of mass passed by? Is the gravity somehow localized? Let me guess, relative to the object travelling at c? So would the spaceship crush itself then? I'm sure I'm missing something, but I can't help but see near-infinite mass as near-infinite gravity, and gravity on that scale seems like it would have an effect on something. And, experimental proof of what? We're talking about thought experiments.
