Sub-Orbital Space Flights & Satellite Exploration
Is the existance of black holes impossable because it causes velocities to exceed the limit of light speed?
Or
Do we need to revise the physical laws because we know that black holes really do exist?
The existence of black holes is not impossible. Current physical laws are not inconstent with the existence of black holes. Black holes do not cause velocities to exceed the speed of light. Physical laws do not need to be revised.
One black hole.
neither…
instead revise your belief about these…
Your premise is wrong, black holes do not “cause velocities to exceed the speed of light”. That is just plain wrong and I have no idea where you might get that idea.
The final result of two orbiting black holes is likely a single black hole equal in mass to the combined mass of the two, and a huge burst of gamma rays as they subsumed each other into one black hole.
Yes, we are fairly certaint that black holes exist and that there is at least one in the center of our galaxy, and every other galaxy.
Black holes have an “escape velocity” that exceeds the speed of light, but there is no physical law broken there since nothing is moving. Obviously if the escape velocity is greater than light, nothing can escape from one.
If 2 black holes are in a stable orbit around their common center of mass, then they will keep orbiting each other forever, just like a binary star system.
If they are losing energy due to friction with gases surronding them, they will spiral into each other and become one big black hole.
Black holes never cause any objects to exceed the speed of light. Even objects falling into them do not fall faster than light.
