How many believe Time Travel is possible? I recently was discussing this on another board with another person that believes it is possible to go forward into time and back into time. Well his thoughts were based upon Superman's theory, you know! if you fly fast enough against the rotation of the earth you go back into time. That's hard to rationalize, going fast enough in any direction would theoretically allow you to go into OUR future but this going back does not sound feasible to me, I mean there is no back, how could you go back, and to where would you go back. It was said if a person could indeed go back into the future and changed the outcome of a death of his Father or Grandfather then he would not exist, well that pretty well defines the outcome of going back for me. I agree with the thought that man can go forward into time if he travels fast enough. This super collider that was built out in the Texas farmlands was mysteriously abandoned after they found that Texas piss ants have a ferocious appetite for electrical wiring insulation. In the neighborhood of 5 billion was wasted purchasing the large land mass that was needed and then the rest of the actual building. Now my thoughts on this was that it was not for experimenting with how the universe was created, a small miniscule explosion moving atoms at super speed!, but actually I think they were experimenting with time travel on a can it be done . Anyway they stopped the construction and it lays abandoned ,or was several years ago, now an European country has a working example but ran into problems after they say a technician made a mistake and caused some damage, after that I haven't heard any more news. I think that technician accidentally stepped in front of the bus, what do you think.
It's impossible, though. The amount of energy sufficient to send even one atom back through time is enough to kill a person (I'm basing this on...something). Not to mention, anything you do in the past would have a significant impact upon history. Your birth is not the only consequence. For instance, just killing Hitler (before he comes into power) wouldn't be the only thing that would change. History would be drastically different. Germany would be a very different place, no doubt.
True dat! but Einstein's Theory of Relativity proves it is possible to go forward, the question is which way do you go, you're not going to waste time circling the globe as all the previous naysayers seem to talk about, but space travel is the only direction that would be meaningful. I read that it would take six months to reach Mars by conventional space travel, and that ship would be moving quite fast, I wonder how much a man or woman would age should they ever attempt this. It will happen eventually if the earth don't blow itself up first. In a sense suppose you did travel so far in space and then returned later, what would your world and people look like, would they be old, probably. I suppose if we read some of Einstein's work in this field we would better understand it. It would be foolish to close our eyes to something that may not be fiction, advancement in science even in our time is beyond anyone's imagination say 40 or 50 years ago. Genetics are the key to understanding what a human can or cannot do. They know and have watched microbes from space that actually are alive and have legs or appendages that can retract when the surroundings exceed several hundred degrees, I lost the url but there were pictures of this life form, and it is a life form although primitive. In the end we will probably blow ourselves up, that's human nature and the mathematical probability get's a bit smaller each day.
Conventional space travel to Mars would be hideous. A space mission like that would require billions of dollars, and for what...? A scouting mission? We can learn plenty about mars without the need of a manned mission. Satellites, probes, what have you. From what we know already, this planet was once habitable. Signs of life (such as water, bacteria, these things) still exist. If terraforming were to ever be thoroughly researched and created then, no doubt, Mars would be top-of-the-list for its initial use. However, our current goal is not to create new equipment, but to simply find earth-like (in other words, ready, and prepared, to be suitable for human life) planets without the need of such equipment.
Doubtful humans would survive long enough to find such planets you mentioned, just suppose it was necessary to leave this planet or face extinction, whats a few bucks if you had viable alternatives that were explored and made possible by people willing to spend the money to make that planet liveable. I saw some really strange photos taken of MARs and there are what appear to be hollow transparent tunnels, most of the specialists say it is geological mutations or something to that effect, but they just look really weird, like spirals used in zBrush only you can see through them. There were also many instances where it appeared the martian seasonal effect had something growing and dying as it does here, one photo shows what appears to be water run off of a large geological formation and it looks rusty! Reaching MARs at this point is not hard, the return is what would take some real new engineering feats. The most important of which is a fuel processing plant so they could get back. The unborn can do this I'll accept my fate already as it is.
As it stands, space travel/planet colonization/space colonies/all sorts of space research are steeped in economic viability. With our current economic situation, we're not going anywhere anytime soon. We can only hope that in the future things will have changed--priorities will be different, the science budget will have been increased, and space won't look so distant after all.
Yes, who's to say what will be done after we're gone, this monetary thing is really what has stymied the human race for a long time. We didn't bring it with us when we were born and in the beginning it had no role as to what we humans were or would become. Someone a very long time ago came up with this bartering system so they might have more by selling off something they had a surplus of. The problem of course is when small rulers came up with a plan to steal or take everything by taxing or otherwise, over night mankind became slaves to someone who had power. No different today than 2 or 3 thousand years ago, we still have that group of people that control what we are. Just look at us today, every unborn child is already in debt and he hasn't taken a breath! It may become necessary in the distant future to rethink this thing called money and come up with something different, the poor are going to revolt and sweep away the upper class who have the wealth, it has already started in some parts of the world. In the end I think this money thing is really depriving us from being what we might have been, doing things and progressing or making the world a better place will not happen using money. Wish I had a bunch of it, but then I would just give it away like all of us do.
'Tis the sad state of our world. It'll be a long time before any significant changes take place. Maybe in a century or two...we'll see some progress. Haha. We have to wait a whole century to see things expand. The only thing that will continue to change is computers and how they function. 50 Years from now computers could be extremely different. Technology will be quite different as well.
That whole theory comes from the fact that if you can go faster than light (which takes infinite energy for anything with mass), then you theoretically you can beat out causality. A cooler way to do it, in theory, is to use wormholes near warped space time. Set up one end near a blackhole, let it sit awhile, and then go in through the other end. You come out in a different time.
I don't think I would want to go into any door of a black hole. I suppose if there is another solar system with suns such as ours then the probability of another life form is very possible, without a sun nothing could mutate or live as we know it, an organism may survive extreme cold simply being dormant or frozen but it might as well be dead.
Time is relative. We all travel through time, every day, every second, every moment, each in relevance to their individual or collective inertial frames of reference. See General and Special Relativity. Old news. So you'd kind of have to be an idiot to not "believe" in time travel, we all do it every moment, and between every moment. Most modern physicists buy into the idea that time travel outside of our "normal", sequential, cause and effect experiences of time is entirely possible, at least, most of the imaginative, big name scientists do. There are very rational, mathematically sound models, that have some obvious paradoxes that are currently unresolved. Most of the current paradigms involve remote, distant technology (such as the ability to generate and manipulate gravitational fields the size of Jupiter/Tyche's) that has yet to be actualized. However, there are some theoretic models of the physical world that would allow time travel, right now, not for physical objects the size of people, mind you, but there are certain Simultaneity theories that would indicate that time is an illusion to begin with, created by our consciousness so that it can process information in a coherent, frame by frame manner, rather than all at once, which would overload not only our current models, but our consciousness itself. The "proof" of this lies in certain interpretations of quantum physics, which are generally permutations and combinations of the three more prominent models, and would feature unproven or speculative hidden variables. There is current evidence that particles/photons/etc can "jump" not only backwards or forward in time, but outside of time altogether, as if it has no effect on them. Keep in mind that "time" is a human construct, and that the universe in no way feels the need to conform to OUR rules. We use rules and laws to try to define how the universe works. The universe recognizes none of our rules or laws, as it does not think or feel. If it did, it would laugh at us, and consider humanity one huge, cosmic joke, in my opinion. At least, I would if I were the universe. The more we think we know, the more we find out that we are completely ignorant, and that alone is too scary for the average human consciousness. Using consciousness as the hidden variable also opens up the doorway for the idea that consciousness itself can travel through time, at will. However, most scientists are extremely resistant to this idea, because it breaks down the ideas of cause and effect relationships altogether, and this is obviously a slippery slope. Not many are willing to admit to themselves that cause, effect, and correlation could be an illusion. The big pitfall that prevents scientists from getting into this model is that at worst, it also opens up the back door for "God", and at best, it actualizes the ideas of Pantheism, Transcendentalism, and the Collective Unconscious. This firmly allows most "rational" minds to dispel it under the pre-assumed pretext of pseudo-science, without the benefit of empirically testing such models, which of course is extremely unscientific, and begs the question of who the "true" pseudo-scientists are. Skepticism is part of the scientific method, but a skeptic's route is the easy, coward's way out, and those that are skeptical of everything end up with nothing, no change, no progress, only their own perpetual doubt which they force themselves to exist within. This is not the goal of science, and never was. A "true" skeptic is the polar opposite of a scientist, though a true scientist must embrace and explore his skepticism and doubts. Most of the currently accepted quantum models (other than the Copenhagen and similar "measurement"/infinite regress interpretations) not only allow for, but RELY on the idea of Quantum Entanglement, and non-local relationships outside of the confines of the space/time continuum. Take that information as you may. Most of all, don't take my word for it. Most of this information is outdated the second I write it; new ideas and paradigms form in the mind faster than the fingers can even keep up. This is the human condition. Go out and learn more on your own, at least half of what I just wrote is already obsolete. Keep in mind that if String Theory or some other Theory Of Everything proves to be a viable paradigm, then everything we think we know about space and time is BEYOND what we think we could even conceive of within terminology such as "outdated" or "obsolete". It never even existed. My advice? Be here now. That's what I do. The past doesn't exist yet, the future is a distant memory. Time does its thing, I do mine. Perhaps we'll meet some day, in the middle of the road, and greet each other as friends. How that happens, I'll let other people decide, for I am only a poor, ignorant fool wandering a lonely, well tread road...
That's very interesting. I'm glad you posted that. In one of my classes time was explained to me as a "river" constantly moving never going backwards. I've heard the theory that time is simply subjective and that it's created for uniformity. An example, in high school you're assigned seats. The teachers give you them based on some notion. Now, come college there are no assigned seats. You sit wherever you like. Why, then, do we constantly sit in the same seats day in-day out. Sure, some times, we have to move around. For the most part, however, I would say we're pretty static. I like to think this is because humans need some form of organization in this chaos. However, this could also be a learned behavior from years of assigned seating. There is one good example, to prove my point, we create religion not for absolution (maybe in some cases) but to answer those "unknowns." People flock to it because they're afraid of what they don't understand. They need some form of answer to their question, in this "chaos." They need some form of organization or uniformity. If I'm wrong, lol, sorry for the long post.
It's not really my place to decide if you are right or wrong, it's yours. I would say that we create science to answer those "unknowns." For me, there is no different between science and religion, they are one and the same if I am willing to accept that the means are irrelevant, and the ends are all that matters. Both strive to further our understanding of ourselves and the universe, through a mixture of empirical, rational, and intuitive means. True science relies more on intuition, true mysticism more on empiricism, and rationalism makes sure that they both chases their tales in circles and constantly have things to disagree about, because gods forbid they ever come to sleep in the same bed. Who would be the top, and who would be the bottom? I would not want to be a part of that gay love-in, it would naturally get very messy, very quickly. Granted, I do not always accept this, it depends upon my mood from moment to moment. I believe that a foolish consistency is the hobgoblin of little minds.
