    1. No. Good guess, though. It’s simply light. In the 1st line, I was thinking in terms of traveling by the speed of light. In the 2nd line, I thinking of an article that I read which said that the color of eyes can vary depending on how they scatter light. Thank for reading!


  1. Love the (very minimalist) thought.. but strictly speaking light is not a time traveller – it is a time RECORDER. It allows us to see (only) into the past (indeed EVERYTHING we can see is in the past), it cannot allow you to travel into the future, although, if you travel at the speed of light (not the same thing as light) you can appear to an observer to travel any distance instantaneously (you can leave from any point in the universe and an observer will see you leave at the same time they see you arrive at their location since both you and light are travelling at the same speed!)

    1. Light and light speed-they are fascinating subjects! I’ve read about how the farthest points of light are in the past. It kind of blows the mind. Thank you for your comments and for visiting my blog πŸ™‚

  2. Kind of you to invite me here! πŸ˜‰

    I agree about how it can blow the mind – as does the unimaginable vastness of our Universe. It is so big we cannot measure it in terms of what we know as measures like metres, kilometers or miles, but in terms of how fast the fastest thing there is is and how long that takes to travel for one year. We cannot even imagine how far one light year is yet the universe is tens of billions of those across (and that’s just the tiny bit we can see with our most powerful telescopes!) I cannot help but ask myself just what it is all for since there is no way i am ever likely to see any part of it other than the planet i was born on?

    In case you can’t already tell, i love physics πŸ˜‰
