mghtymoop wrote:speak for youself, the maths is simple calc and geometry with an extra axis, i daresay most of us can do it, at least everyone who is capable of understanding any text written on dimensional physics.

pat wrote:First, the laws of gravity allow elliptical orbits in three-space. Second, part of the assumption of this thread is that gravity would be an inverse-cube law rather than an inverse-square law.

mghtymoop wrote:pats calculations are lacking in one very important part. you cannot only integrate or differentiate the force of gravity, you must also integrate or differentiate the vector quantity of velocity as in 4d velocity is 3d acceleration and in 2d velocity is 3d displacement.
mghtymoop wrote:moving between dimensions needs calculous simply because if you need to increase a power to give a new dimension there is no other simpler way. it also doesn't matter how the object is moving the object itself is made up of the integral of 3d matter so any motion equations must be integrated, 3d acceleration is 4d velocity, this is why we have gravity that remains constant for a constant mass or inertia that remains constant for a constant rate of acceleration.
mghtymoop wrote:you failed physics? perhaps i should have a look at the new syllabus but i know that the undergrads i have working for me reckon that with the new calculators physics is now one of the easier TEE, i don't care what you were ranked in a TEE subject really, their only there to assess your capability to undergo study at a university and nothing to do with actually learning anything.
mghtymoop wrote:and your also right that relativity plays no part in newtons laws, but it doesn't even enter into the debate because you are integrating into the fourth dimension, which is most probably the last dimension and also is in fact a spatial dimension so you must integrate the equations of motion not only over the spatial components but also the temporal components, and if the 5th dimension was time in tetraspace that would only be because the 4d beings interpreted it that way, it would still have no effect upon our interpretation of the 4th dimension as time.
