Oh! So you mean the centrifugal force does exist?


No, it doesn't.

Does that mean you agree with me that cold radiation can/does exist?

However, I can't agree with you that the centrifugal force does not exist :-(
As I wrote in my previous post, if there were no centrifugal force opposing the (centripetal) force of gravity, then Earth would be pulled straight down towards the Sun. Newton's third law states that every force has an equal and opposite force. In the case of the Earth's orbit, the gravitational force is opposed by the equal and opposite centrifugal force, fictitious or not.

But, let's not fall out about it :-)
