Black hole vs the speed of light

[weeman]

The escape velocity of a blackhole doesn't necessarily have to be faster than the speed of light for it to suck in light and appear black! It might be exactly the speed of light, which is why we can't see the light because it is essentially traveling an infinite distance to get out of the blackhole's grasp. <br /><br />Lets say you're running on a treadmill at 8 mph, if the treadmill is moving at 8 mph you will stay on the exact same spot on the treadmill forever (if you maintain your speed and/or the power doesn't go out <img src="/images/icons/smile.gif" /> ). <br /><br />This is the same principle in a blackhole, the light is traveling at its regular speed, but the escape velocity directly matches its speed. It's as if the light is traveling on a path that is neverending. <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">Techies: We do it in the dark. </font></strong></p><p><font color="#0000ff"><strong>"Put your hand on a stove for a minute and it seems like an hour.

Thanks for clarity.Can I use this to say that if a man falls in black hole,he may come oue in another spacetime in this universe or another universe?He can pass throgh singularity<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Can it explain if a man falling in a black hole can come out through singularity to another space time in this universe or another universe?<br /><br /><br /><br /><br /><br />/

<font color="yellow"><br /> if a man falls in black hole,he may come oue in another spacetime in this universe or another universe?He can pass throgh singularity </font><br /><br />The singularity is 1 dimensional space with no time. This means that it's in our universe, but not in our 4 dimensional space/time. The answer to your question is yes, there is the possibility (probability) that some of this poor man's particles (as waves) might make it thru the singularity by Quantum Tunneling. And come out in our space/time, or another space/time universe.<br /> <div class="Discussion_UserSignature"> <p><font size="4"><strong></strong></font></p> </div>

There are tidal forces in event horizon.As you near singularity atoms ,quarks break.But some thing quantum tunnelig may help us bypass these and if we catch a worm,hole,we reach elsewhere.in this universe or another universe.We may make time travel also.
