Click For Summary
Launching a star at twice the speed of light is deemed impossible under current physical laws. The discussion speculates on potential outcomes, such as the creation of rifts in spacetime, electromagnetic shockwaves, and gravitational waves. It also raises questions about the stability of atomic structures at such speeds. However, the consensus emphasizes that these scenarios are purely hypothetical and not grounded in scientific reality. The forum prioritizes discussions based on established scientific principles rather than fantastical scenarios.

Let's say you were to launch a star at a speed that is twice the speed of light.
 
Physics news on Phys.org
Isn't that impossible?
 
Hell yes, but let's try to imagine what would happen anyways. Would the star tear a rift in timespace? Would there be an EM shockwave? Gravitational waves? Relativistic effects? Would the atoms in the star break apart into subatomic particles? What do you think would happen?
 
It turns into a herd of invisible pink unicorns.

The question you are asking is exactly this "Assume the laws of physics don't apply and then figure out what the laws of physics say about <insert nonsense of your choice>"

This forum is not for that kind of question. It's for actual science.

Thread 'EPR revisited'

In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$ \frac{1}{\sqrt{2}}(|0>_A|1>_B+|1>_A|0>_B) $$ At point A, a measurement is made. The state then collapses to $$ |a>_A|b>_B, \{a,b\}=\{0,1\} $$ We assume that A has the state ##|a>_A## and B has ##|b>_B## simultaneously, i.e., when their synchronized clocks both read time T However, in other inertial frames, due to the relativity of simultaneity, the moment when B has ##|b>_B##...
