    Is this bending also what is meant by refraction of light? Like Dr. M mentioned -glass, water, etc

    Light isn’t straight confirmed.

      I mean have you seen light passing through a prism? A rainbow appears. Light is definitely not straight.

    *Making money is an action. Keeping money is behavior, but “growing money is wisdom”. I found this out a week ago after getting a $10,000 return on my $3,000 investment in 7 days*

    Thats essentially how i built a superhero with the power to control light, essentially an illusionist on steroids. Take it a step further and suddenly hes a jedi knight

    Light never slows down. It only appears to slow because it is constructive in any mediun.

    What makes the speed of light increase again to normal after light get through a medium?

    Light can also take unexpected turns, if you punch tiny holes into a solid surface. It’s actually much more crazy how that can bend light than you think.

    Light can bend at angles that seem absolutely crazy by doing this on a mirrored surface 📐 0.0001° to 360°

    All I need to say is a black hole, if you look at a picture of one(or an illustration of one) you can see light bending around it

      Gravity on steroids…

      That ring is the event horizon … The last point light can escape. Seen only when a black hole is devouring another star or planet … It’s ripping apart and spiralling inwards. The poles are highly magnetic as well, but it’s the event horizon that emits magnetic waves … Not the black hole itself

    The ability to use glass to bend light completely around it and camouflage something inside, is this theoretical or have experiments been conducted?

    The kid just wanted to know the answer to his homework.

    How can gravity bend light if you can’t prove it outside of an argument that at base is just a definition of mass?

    • Νικόλας Πούλος

      October 10, 2023 at 9:06 am

      Because you can observe it by doing experiments

    Yes, it’s called fiber optics

    Interesting! I am confused!

  26. David Slay

    October 13, 2023 at 2:45 pm

    Wait…so if you can bend light and it slows down and you eventually slow it down to actually see it moving slowly enough?

    NOOOO, THAT IS AWESOME
