  1. A bit off the subject, but would like to comment on your perception of perception not being reality. I tend to think, my reality may not be your reality, due to different perceptions, but it is still my reality. To answer OP question, there is a present, as explained so thoroughly by aboleth_lich with the present being few milliseconds, it still exists. Some good reads on the subject, well at least I found interesting, are by Kant and St Augustine. So, yeah this question of time in the past, present, and future has been pondered for a long time. For example, back to the subject of perception, Is space and time dependent upon the mind for existence to identify the present,led me to an article from the Stanford Encyclopedia of Philosophy, on Kant's Views on Space and Time, but a bit over my comprehension (still need to sort through his philosophy). Now, I am not inferring that space and time can not exist without my mind, but more is my or your perception of space and time dependent on our minds? St Augustine writings suggest, "knowledge" of time can basically not exist unless someone has a way to measure the passing of time. "I said then even now, we measure times as they pass, in order to be able to say, this time is twice so much as that one; or, this is just so much as that; and so of any other parts of time, which be measurable. Wherefore, as I said, we measure times as they pass. And if any should ask me, "How knowest thou?" I might answer, "I know, that we do measure, nor can we measure things that are not; and things past and to come, are not." But time present how do we measure, seeing it hath no space? It is measured while passing, but when it shall have passed, it is not measured; for there will be nothing to be measured. But whence, by what way, and whither passes it while it is a measuring? whence, but from the future? Which way, but through the present? whither, but into the past? From that therefore, which is not yet, through that, which hath no space, into that, which now is not. Yet what do we measure, if not time in some space? For we do not say, single, and double, and triple, and equal, or any other like way that we speak of time, except of spaces of times. In what space then do we measure time passing? In the future, whence it passeth through? But what is not yet, we measure not. Or in the present, by which it passes? but no space, we do not measure: or in the past, to which it passes? But neither do we measure that, which now is not." http://www.sacred-texts.com/chr/augconf/aug11.htm So, thanks for asking such an interesting question about the present time. Enjoyed reading all the replies.
  2. With all the discussions about traveling back in time, I do not think, we will ever transport our physical bodies back. Although, we get a glimpse into the past by looking up into the skies. According to astronomers, "When we look out at space, we are looking back in time. The light arriving at our location from the farthest objects in the universe is light that left those objects billions of years ago, so we see them as they appeared long ago." http://hubblesite.org/hubble_discoveries/breakthroughs/cosmology If this is the closest we ever get to going back in time, is this enough for you?
  3. After reading your reply under another thread Your mind as a time machine, you mention some concepts that I was unaware of; such as, particle accelerators. "A particle accelerator is a machine that accelerates particles to extremely high energies". Institut für Hochenergiephysik Is time travel possible? Well, okay I have heard of the LHC at CERN - Geneva, but did not put two and two together, at first. Anyways, you also bring up "experiment involving Special Relativistic time travel". Quick search took me to a NASA question and answer page, talking about how time slows down, as explained below. Is time travel possible? http://spaceplace.nasa.gov/review/dr-marc-space/time-travel.html "The great 20th century scientist Albert Einstein developed a theory called Special Relativity. The ideas of Special Relativity are very hard to imagine because they aren't about what we experience in everyday life, but scientists have confirmed them. This theory says that space and time are really aspects of the same thing—space-time. There's a speed limit of 300,000 kilometers per second (or 186,000 miles per second) for anything that travels through space-time, and light always travels the speed limit through empty space. Special Relativity also says that a surprising thing happens when you move through space-time, especially when your speed relative to other objects is close to the speed of light. Time goes slower for you than for the people you left behind. You won't notice this effect until you return to those stationary people. Say you were 15 years old when you left Earth in a spacecraft traveling at about 99.5% of the speed of light (which is much faster than we can achieve now), and celebrated only five birthdays during your space voyage. When you get home at the age of 20, you would find that all your classmates were 65 years old, retired, and enjoying their grandchildren! Because time passed more slowly for you, you will have experienced only five years of life, while your classmates will have experienced a full 50 years" Article goes on to provide a link talking about slowing down atoms and building accurate clocks. http://spaceplace.nasa.gov/review/momentum3/ "Scientists have found a way to super-cool atoms by slowing them down using laser beams. Lasers are a particular kind of "well-organized" light. The light acts kind of like very fast moving particles with . . . you guessed it . . . momentum! The light particles slow down the atoms that come at them from the opposite direction. If the lasers are pointing toward the same spot from several different directions, the atoms can't go much of anywhere." Okay, So my point (besides, thanking you for the above information in your reply, which led me to these concepts) was to ask is this what you are referring to when you mention experiments already taking place? Granted, this is a bit over my head. I am not an expert, nor spent any length of time researching space/time. Also, again in my limited understanding, do you or others think time travel could be possible in the future by slowing down atoms vs speeding up particle accelerators?
  4. But... Mr. Sad Face has a time machine. He also witnessed the accident and as a result suffers from PTSD because he saw it happen and couldn't do anything to stop it. He's decided to use his gadget to change history by saving everyone from the accident. And so he does. There's no accident; there's no sound drawing your parents to the scene - they continue walking in opposite directions. They never meet and you are never born. In fact, they each marry someone else and have entire sets of children that were never born in the original history. A hundred years later all of the hundreds of resulting progeny have engaged in hundreds of marriages that never existed in the original history resulting in thousands of children being born that never existed in the original...et sic in aeternum. Do you really want to change the past? While I agree changing the past is not a good idea, I tend to believe fate would still bring your parents together. As @Einstein points out, "It probably doesn't matter if you change anything. If all the possibilities already exist, then you would merely just be following an alternate path through time." Or in the case of the OP and the suggestion of stopping Hitler, if not Hitler, someone else. After all, it was not a one man show and the tragic events were bound to happen either way.
  5. You bring up a valid point about the goal of time travel is to change past events. Yet, I am inclined to agree with some of the above posters that changing past events is perhaps not the wisest course of action. Nor would it be my goal. Although, there already seems to be a discussion thread on this subject Would it be right to go back and change something, I just wanted to comment here, too. For me, I would rather be a time tourist, as mentioned by @ CallipygianGamine Interesting analysis about the movie Inception. Now, this was one mind-blowing movie! It was like asking yourself what was real and what was in your mind - dream. Got to say having an object to tell the difference was quite interesting and not sure if it stopped spinning at the end?
  6. I agree with mr paradox and Gpa. The Dark Ages was not worldwide happening and history tends to repeat itself. It is just a matter of what you want to focus on. You can look at the world full of pessimism or optimism. To travel back in time to this era the people were primitive by today's standards for most people, but not oppressed to the degree implied. I would be interested for anyone to step up with information about anytime in history where the majority was rich and the minority poor. Also, we still have people looking for immorality. So, no, I do not think we are living in the Dark Ages, but some people are choosing to live in their personal darkness, and sadly some regions of the world are still living without all the benefits of modern technological resources.
  7. If you suddenly were teleported 100 years back in time, what would the first thing you do be? I would rather have a planned trip, then I would do something similar to the character in that movie, Somewhere in Time. He was wearing the clothing attire for the period, money in his pocket and knew exactly who he was looking for on his time travel journey. But you add "suddenly". Well, thus far, the responses have been spot on. I would have a panic attack because I would not want to go back in time, unless planned and knew I could return. So, the first thing I would do is try to find a way back to the present. Eventually, I would settle down into my new reality. Exciting events happened in 1915; nevertheless, on this day in history back on 24 May 2015 is the beginnings of recorded telephone conversations with Thomas Edison's inventing the telescibe. How surprised my contacts would be be to find out out about today's iphones with video recording capabilities sent instantly around the world!
  8. Your compassion of long-term memory vs short-term memory in conjunction with your "brain working faster then your mouth" reminds me of an article from the National Center for Biotechnology Information, U.S. National Library of Medicine, What are the differences between long-term, short-term, and working memory? by Nelson Cowan. The idea of a working memory has to do with basically the present. For example, working a math problem in your head or while baking - recalling that you already added the flour, so you do not do it twice. It is a fascinating topic. I think, in regards to the topic at hand, Your mind as a time machine, we would, also, need a functioning "working memory" along with short and long term memories. While I agree with you about the concept of "mental" time travel via our memories, I do not always recall my feelings and emotions experienced for "all" my memories. Granted some memories are vivid; however, some are merely moments in time of an event.
  9. Oh, you made me laugh aloud, with your comment, we could cheat ourselves. If this was the case, I think our current self, upon return, could find ourselves in a different financial position, thus not cheating ourselves. You know similar to Back to the Future scenario. Again, you would have the possibility of changing a number of areas in your life, that you may surprise you. Maybe, to your surprise in ways that may not appreciate. After all, as the saying goes, money does not always equal happiness. Exactly what your former self does with the winnings seems kind of risky, indeed!
  10. Thanks for the link. Appreciate how it is layman's terms, so it was a quick read. What I found of importance and think it will play into future research on memory is the fact that our memories are not stored in a "filing cabinet" I remember years ago reading on memory and it was taught that we needed to know how to compartmentalize our memories in order to successfully and easily retrieve them. Of course, to do this was paying attention to attributes of certain events or information including the "sights, sounds, words, emotions". Now research is saying one memory or one piece of information is actually stored in different parts of our brain according to the "sights, sounds, words, emotions". This make more sense that we have a "distributed memory".
  11. Oh lol. It may be clearly an old thread, but I still benefited because I never knew about tow or part three as mentioned in the above posts. Now, in regards to other movies and the consequences, I kind of learn towards consequences highlighted. Maybe you could give an example in which the consequences were marginalized? Then again, I do not necessarily watch movies for the factual information, unless it is a documentary. Of course, it bothers the heck out of me, when a movie is to far fetched or poorly made. This causes me to lose interest.
  12. Well, I can be a bit repetitive at times, too. So, this does does not bother me, especially if I am seriously interested in a subject. First, I agree childhood memories would lack some (or much) information. But here is what interests me, what about the chance to regain memories, provided you are not changing events. So, in response to your question about the benefit of going to a destination within our life that we do not recall so vividly, it provides an incentive and interest for me to go back to this point in time.
  13. Okay. I thought about your questions and read the responses, thus far. I choose B. Return to the present and find myself rich and remember winning? Yet, as mentioned this would change events for not only ourselves , but others too. If I were to time travel in hopes of winning the lottery, I would make two time travel trips into the future. The first one to find out the winning numbers and the second one to a time just a few days before the winning numbers drawn. This way, when I went back to the point of my original point in life, I would not have changed events up to this point, but would know and plan for my winning in the near future.
  14. What I should have said is we have lot more to learn about eg research on memories that we could benefit from especially in regards to memory loss (Alzheimer's). I have not doubt to the creditability and have complete agreement that we begin to retain memory, as a fetus. I think you are fortunate to have met a doctor that provided more insight into this research. Perhaps you can provide some sort of link to his research or maybe he was relaying research conducted by others? I have tried to locate research that deals with long-term memory, thus far, only found short-term memory. Today, thanks to you, I have started a new search and found links to research from the Society for Research in Child Development. I am specifically looking for some research by researchers from the Netherlands because of their research mentioned in Scientific American, a Division of Nature America, Inc. Now, back to the subject on time travel and memories, I was pondering the idea about the ability to travel back in time based on memories from childhood. I think, when we are very young before our language develops, we base our memories more in glimpses of images recalled. Still maybe this could be enough information to travel back in time? @Ceolaric because time travel is just an idea at this point, who knows maybe in the future we could go back in a time based in our life based on a image in our memory?
  15. I agree, dreams are just dreams, not memories. At the same time dreams can stem from memories. So memories can have an effect on dreams. You may have not directly experienced your above mentioned experiences, but you have heard of them or maybe seen them as an observer either first hand or in a movie, etc. Even though, I agree dreams are just dreams, does not make dreams less relevant for some people.
