  1. In which case, yes, all directions lead to the singularity, so if you speed up, no matter what direction you accelerate in, you are accelerating towards the singularity and will reach it sooner.

    The point of the thread is the question of whether or not the force of the Singularity will cancel itself out once past the event horizon. Because if every direction leads to Singularity, then Singularity will pull you from every direction.


    You are still in three-dimensional space, so there are still three orthogonal directions.

    I know, they all lead to the Singularity


    MigL, the problem isn't that there's only one direction, problem is that EVERY direction leads to the Singularity.


    Edit: mistyped xP

  3. Another curious thing is that if you free fall towards the singularity you will get there very quickly. If you try and avoid that, for example, by using your rocket engines to go in a different direction, you will actually get to the singularity sooner. (Don't ask me to explain why that is, but I was told it is the case by someone who can do the math.)

    By definition, within the event horizon, there is no "different direction". Every direction leads to the Singularity xD

  4. There is no difference in the way a BH acts gravitationally from an equivalent mass which is not a BH.

    Tidal forces exist within the event horizon.

    As a matter of fact, for a galactic center BH ( millions of solar masses ), the density required for gravitational collapse is equivalent to that of water, and you would not feel any tidal effect until you've passed through the event horizon and are well on your way to the ( possible ) singularity.


    What 'all possible paths lead to the singularity' means is that most paths are impossible once having passed the event horizon.

    The only available ( possible ) path left, leads to the singularity, and is usually stated as the only destination in your future is the singularity.

    Yeah, I got that within event horizon, the only possible path is towards the singularity.


    As the space has been warped so much that traveling in any direction, forward, backwards, left, right, up or down, will get you closer to the singularity. If that is true, singularity should be pulling you towards it in every direction.


    So, I am having a hard time grasping how tidal forces will still exist

  5. Interesting question. A couple of thoughts...


    Although all paths lead to the singularity, they may not all have the same length - and therefore not the same gravitational force.

    Distance from your head to the singularity should be different from the distance from your foot to the singularity.


    However... if all direction leads to the singularity then singularity will pull your head in every direction towards it.


    It will also pull your feet in every direction towards it.


    So the net force on your head should equal net force on your feet. You should be able to generalize this so that it applies to every point on your body.


    It seems like the tidal force should only be felt before you enter the event horizon, but not after...

  6. What do you mean? If all paths lead you towards the singularity, then any direction you face should also lead you towards the singularity.


    The singularity should be the same distance away from you in every direction because every direction leads towards it.


    If that's the case, then the pull towards the singularity should be in every direction by exactly the same amount

  7. Yes, there is no path to escape, because all path leads to the singularity. Thus, every direction leads towards singularity. So, you are getting pulled towards singularity in every direction.


    But, if you get pulled towards the singularity in every direction, they should cancel out.

  8. Okay, most sources say that once you get past the event horizon, you will be ripped apart by the gravity and die. Yet, they also say that once you pass event horizon, every direction leads to the singularity.


    This doesn't make sense. If every direction leads to the singularity and you get pulled toward the singularity then you are getting pulled towards the singularity in every direction... Wouldn't the forces cancel out?


    Also, since the singularity is infinitesimally small, wouldn't it take you forever to actually get to the singularity as every part of you is approaching that which is infinite?

  9. Create a dystopian society where the government stores the semen and eggs of its citizens and then make them infertile.


    Wait until the said citizens die and if the time of their death is greater than the average life expectency of the total population, create more of them.


    Rinse and repeat. Sure, there will be outliers and many other variables like wealth... But with law of large numbers + time, there should be some results.


    On a more serious note, although it's too much for humans, have there been a study like this with creatures with shorter life spans like Lab Rats? Would be interesting to find the mutations that they obtain to be able to live longer
