    Why do you think you know what I mean?

    You wouldn't deny it otherwise...

    This begots the definition of pain. Is cold, inherently painful to Consciousness, or is it merely, our brains interpreting pain in such a way, that if, we could have a positron brain, and the brain was cold, it would feel pleasurable and not of pain.

    Deny what, and where?

    That it's a different knife. And a different pair of scissors!

    Gamelord, the brain itself is devoid of nerves and cannot feel warmth or cold. ☺

    If we had a "positron" brain our lives would be measured in milliseconds. The positrons would annihilate the electrons on nearby molecules, releasing 1/2MC^2 energy.

    yes but it interprets input as cold, so who knows what a positron brain would feel?

    No electrons would be allowed in the positron brain.

    So you'd make it of antimatter? OK - then you have an even bigger bang. A brain weighs about 1.4 kilograms; if that combined with regular matter the resulting explosion would be about 30 megatons. Only one bomb around that size was ever used - the Tsar Bomba, developed by Russia. It destroyed buildings for hundreds of miles around the test site.

    Lie detectors are innacurate. Second, why was he not given a DNA test to test for abnormalities of DNA? Surely someone 4000 years in the future would have certain abnormalities. And why was his face blurred? Surely his face should be shown as to potentially identify him as a 2018 earth citizen by friends or family.

    That is why we put some kind of layer around the brain so that it doesn't interact with regular matter.

    Gamelord! I'd be more inter-rested to know if time-travel is illegal in the future!

    Yeah, a layer of something that isn't matter or anti-matter. Say, "don'tmatter".

    everything may be illegal in the future. that is why we need travel, to fight for our freedom.

    let me put it like this. if positrons were so volatile then there would always be nuclear explosions in space. There isn't, so something about them is stable.

    OK. So you'd have to invent some sort of force field that can hold matter away from antimatter. (Of course if you did that, the applications for defense, fusion energy and spacecraft would far eclipse any benefits from having an antimatter brain.)
    There are nuclear explosions in space (and on Earth) all the time. For a simple example, go outside during the day and look at the big glowing thing in the sky. For a more subtle example, google "pair production."

    To go backwards in time involves the whole Universe . Every point of mass and energy , at every moment , even at the point of going back , in time .

    Further what if millions and billions of beings , in the Universe , want to travel back in time .....the Universe would be a mess .

    No , backward time travel is not possible .

    While there are some positrons in space which we detect as cosmic rays striking our atmosphere, they are not as prevalent as you seem to believe. The total energy released by these positrons annihilating with electrons upon hitting the atmosphere equates to ~ 1/100000000000000 that of sunlight striking the Earth. In other words, there aren't enough positrons out there to produce much in the way of nuclear explosions. You really need to check up on your facts before making assertions like this.

    Time travel is just as important as your human space travel. Space travel would not "eclipse" time travel and I think people would find time-travel more interesting.

    First of all, there would be elite time lords, who have the best interest of all beings and animals in mind. Random members of the public would not be allowed to until they've proven their worth to wield the metaphorical excalibur.

    I think Time Travel has something to do with consciousness. This is because, imagine you are a Greek 2000 years ago. The universe of 2000 years ago is what you see.
    Yet, you are you or me right now. It didn't change the universe, it just changed our perception of the universe. So Time Travel would not change the whole Universe, but rather, the perception Consciousness has of the universe. Of course, I may be wrong, since we don't know enough about Time Travel to say for certain.

    ?? Uh, OK. That had nothing to do with the thread, but OK.

    It was a response to your post, which i quoted.

    Are you basing this on your decades of research into positrons as a Ph.D.?
