If an astronaut is falling into a black hole then her image would fade to red as she approaches the event horizon, as see from the ship hovering safely above. Before she passed the event horizon the command ship would lose her image all together. Would it be fair to say that the situation would...
Thank you for elucidating that point. Still, it is hard to see how the ship's observation could be contrary to the clocks on Earth and the space craft. If time is whizzing by on earth, why would the telescope on board the craft see a world nearly frozen in time? If the craft came to an abrupt...
Hi Folks-I am interested in knowing whether, in actual practice, people on Earth would see their 99% of c colleagues moving around in fast forward motion and if the reverse would be true from the vantage point of the relativistic astronauts who are moving away from earth. I suspect that since...
Thank you for clarifying about the the two perscpectives. BTW I just found dozens of serious articles about stars moving at near the speed of light. They have not yet been observed because they a far away and faint but astronomers believe that when two supermassive black holes collide, as will...
Would we find black holes moving near the speed of light in nature? Orbiting very close together or blasted out of a violent galactic nucleous? Or is it just a thought experiment?
If the black hole were accelerating toward Earth near the speed of light and a device were dropped into the front of it which attempted to send out a signal; is it possible that the red shifting of the signal might be canceled by the blue shifting of the same signal as it hurled toward us at...
When I thought of this possibility I was more interested in the ramifications for the gravity of the black hole combined with the relativistic mass increase of the black hole as it approaches c. What effect would this have on the imaginary time which would be experienced by an object falling...
