Hi, so i have a fairly good understanding of most of the concepts relating to inertia. but my question is what is the force felt by the observer while accelerating. for example the force gravity can be described as space bending into shapes around the body of mass, the other can be described as...

Also is there a formula to find the relationship between the strength of the magnet (electromagnet) and the repulsive force on the copper.

Hi so I am aware that when copper is introduced to a magnetic field it will generate it's own that repels the field inducing it, this repulsive force is weak but how strong of a magnetic field would it take to generate a considerable amount of force on the copper

well that got m hopes up but thanks anyway

has anyone conducted a successful experiment proving closed timelike curves via post selection and quantum entanglment.

so also i have been reading that ds^2 is the an invariant in a solution metric what does that mean and what could be a geometric interpretation ds^2 in a metric.

hi every, what part of EFE are the solutions (such as kerr ) for. Since most of them if not all don't require a mass or energy In there metric equation. I always just assume it was a solution to the metric tensor. Though i do know that the swartzschild metric requires a value for mass in its...

Oh well I get swartzschild has his radius equation built into his metric wh8ch uses mass

Thanks everyone but I have one more question what part of EFE are the solutions (such as kerr ) for. Since most of them if not all don't require a mass or energy In there metric equation. I always just assume it was a solution to the metric tensor

I understand that GR allows for a method of time travel using closed time like curves (CTC)s. anyway i have a few question about this, first of is there some sort of (relativaly short) equation that discribes this. So my second question is based of a something i read in this thesis paper...

thanks a lot but so is there a fairly simple to equation that some what accurately predict the bend in the light

is it possible that gravity reduce the speed of light, and addtionally does anyone know an equation to calculate the exact deflection of light due to gravity.

thanks but i meant to ask is there like a unit of spacetime curve or is there another way to determine the magnitude of the curve with the value of Gμμ

Hi I have been trying to teach my self the basics of Einsteins Field Equations, because I find them extremely interesting and there is a huge lack of EFE in the Canadian high school curriculum. I have been trying to under stand the equation G=8pi*(G/c^2)T. I get what the equation is for ( the...

the article is actually really long (It more of like a paper) <crackpot link removed> the part about this matter is towards the part appendix "A" about Newtonian laws.
