can any celestal body or anything rotate at speed of 90 degree per second with a radius of
of more than or equal to 3 X 10 ^ 8 metre ?
is it possible?
 
Physics news on Phys.org
faster than speed of light ?

ok guys
suppose a body or something with radius of more than or equal to 3X10^8 meters is rotating at speed of 90 degree /sec : then a point at crust of top layer will travel at speed of 3√3 X10^8 m/s (using pythagoras theoram ) so have i done anything wrong please correct me ?
thank you

Arithmetic may be correct, but it would be physically impossible.

Thread 'Can this experiment break Lorentz symmetry?'

1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...

Thread 'A sufficient condition for integrability of equation ##\nabla g=0##'

In Philippe G. Ciarlet's book 'An introduction to differential geometry', He gives the integrability conditions of the differential equations like this: $$ \partial_{i} F_{lj}=L^p_{ij} F_{lp},\,\,\,F_{ij}(x_0)=F^0_{ij}. $$ The integrability conditions for the existence of a global solution ##F_{lj}## is: $$ R^i_{jkl}\equiv\partial_k L^i_{jl}-\partial_l L^i_{jk}+L^h_{jl} L^i_{hk}-L^h_{jk} L^i_{hl}=0 $$ Then from the equation: $$\nabla_b e_a= \Gamma^c_{ab} e_c$$ Using cartesian basis ## e_I...
