    Time is affected by gravity. Gravity is partially affected by velocity and partially by momentum. The greater the velocity and the greater the momentum of an object, the greater the gravity, and therefore, the slower the time.

    @Zee:
    When you go at relativistic speeds, time slows down appreciably. This is relativity: no metter the observer’s frame of reference, they will always see light as going the speed of light. As the actual velocity of light is the same, your reference point – time – is slowed. Hence, you experience things differently from those around you not going relativistic speeds.

    Carl said, “We are star stuff” and “a way for the cosmos to know itself.”

    All the atoms on earth and in our bodies came from supernova that blew up over 5 billion years ago.
    Aren’t we all just walking, talking stardust — this cosmos become AWAKE and looking back at itself? — and aren’t we intimately connected to it all?

    We are this wonder called life become AWAKE
    Please enjoy the dance.

    And ultimately there’s nothing that separates us from others in this grand mystery. Please be kind.

    but, but, but, but, but, but why?

  5. Zee96969696 says:

    no, you got it all wrong

  6. MrCerialKiller says:

    agree, thats a good episode

    Thats actually a function of the brain. When it is overloaded with sensation, tunnel vision results as it struggles to cope with the speed of the input, so it tosses peripheral vision as unnecessary and concentrates on whats close to the focal point.

    the younger brother reminds me of the dog waiting for fry in futurama lol

  9. SeventhMind says:

    I dont understand. When you go very fast you start moving very slowly?

    listen to Michael tsarion on the youtube. He is the worlds premier conspiracy researcher/lecturer/author. Dr. Bill Deagle and Alexandre Dumas pere are highly informative as well.

  11. Tharumus says:

    No you don’t. It only happens when your going very close to the speed of light. That means around .8c which corresponds to a speed of 240,000 kilometers a second. At 150 mph your only going about .067 kilometers a second.

  12. longded says:

    @MrIcePho3nix but in view of the distances to travel the people of earth would all be gone by the time you got back so who would there be to show the discovery ? surely a worm hole is the way to go if you, unless you wanna send colonys ? infect the rest of the universe perhaps? perhaps them roswel aliens was people from earth that went off so long that they evolved slightly and clocked the universe? make a great play!

    I see this when I’m on my Yamaha R6 going 150 mph. It’s a very calming experience believe it or not.

  14. luarionte says:

    The circle reflects the space time dilation that occures with the high speed!

  15. iroveashe says:

    I think for the same reason you’d see him get thiner.

  16. MrIcePho3nix says:

    Hey, he said funny things have to happen close to the speed of light. Blue- and red-shift are our eyes’ way of adjusting to visible and non-visible light. As you travel closer to the speed of light, you’re only able to see light that is traveling at a similar speed, that being the light directly in front of you. Outside of the red-shifted zone, wavelengths APPEAR to have increased in wavelegth, outside your the spectrum of visible light.

    That didn’t answer your question, did it?

  17. Haydeez64 says:

    @NoCrispin But WHY would the distortion take place at all?

  18. NoCrispin says:

    You forgot about the distortion that would take place.

  19. Haydeez64 says:

    Why would you see a circular distortion close to that speed? I’d think that you would just see the center blue shifted and the edges red shifted… without the circle.

  20. akamola11 says:

    That’s correct. Which is why you will age faster than the boy on the bike.

  21. barcodekillers says:

    If that were so true, then I would see the boy on the bike not even moving in my time reference frame. Slower than a snail for a century and all brightly blue and red colored.

    second!
