    Debunking the Myth: The Truth About Sunlight and Color Scattering

    This is not entirely true. If we refract sunlight we will notice that you don't get a perfect spectrum, some of the lines will be missing, this is true for all stars. However I think the sun has a fairly complete spectrum. This is due to the nature of the gas that comprises the star

    Rotating Space Station & Gravity: A General Relativity Exploration

    I agree with your circular arch. It appears that a perfect gravity simulation can't be achieved through a rotating body. However, I would assume that the anomalies get lesser as the radius of the space station is increased. But I'm still not sure if anyone has answered my question. I am aware...

    Rotating Space Station & Gravity: A General Relativity Exploration

    So say you were on the floor and the station was rotating at an extremely high rate, fast enough to notice such relativistic effects. Would the person on the floor notice any differences whatsoever compared to being stationary on earth? say they threw a ball straight in the air (but not past...

    Rotating Space Station & Gravity: A General Relativity Exploration

    It is easy to see how a rotating space station can simulate gravity through the centripetal force. Examples are swinging a cup of water in an arch, or theme park rides. I saw another discussion about this very topic and it got me interested and I was researching it, however everything I found...

    How do we know that gravity is an attractive force?

    That is a very interesting idea you have there Meatbot. I can see how that would work in some cases. However, not only would it be hard to explain why a vacuum would collapes, but how does it account for the density of the object? for example, 2 objects can have the exact same volume which...
