Well all I can say is that it took me nearly the entire Sunday afternoon to read (just once) the most recent posts. The award for the longest post of course goes to the undisputed King Alex

you must have been with a few characters of being too long, in that post down the screen a bit.
It seems to me that this thread (as Mill suggested) is morphing
It is certainly no longer about Black Holes. Somehow Alex has managed to turn it into an issue of Not believing what scientist's say, especially if they have constructed working models based on pure mathematics.
Hmnnnn it's hard to comment on any specific aspect, because so many thread tangents have been entered into the thread.
Essentially, I would like to see the DNA of the two new people on the island to confirm their progeny.
As for acceleration in a short period of time, yes of course that is hard to understand, no argument there. I find 500 or 600 miles per hour hard to understand, but still believe it
I guess that the density of a Neutron star would be another thing you doubt, no way you can have 50 billion tons in a single teaspoon - no way hey
Of course, every time you state that you find something hard to imagine or believe, there is an equal and opposite opportunity to marvel at how amazing that is.
I find it hard to understand that Jupiter is made of gas, but I believe that it is, not that I have personally been there and touched it.
Scepticism for the sake of scepticism is harmful to your development. Sure there are errors and cheats and intentional misrepresentations for personal gain, but there is also a lot of correct, proven amazing facts that IMHO by far outweigh the rouge stuff that might appear from time to time.
No one is suggesting that you blindly believe and accept everything you read or hear, certainly not, but you must give an equal share of your determination in something being incorrect as to it being correct, otherwise it is you that is flawed.
Appraise every new piece of information firstly in isolation then in context, review it, then peer review it, then think about it and make an informed decision as to whether you accept something or not.
Remember the scientific approach is on your side Alex, that is why most things stay as a Theory, very few things make it to the Law status. This precautionary process is their expressly to protect healthy scepticism like yours, providing that when something is proven, you do the right thing and acknowledge it.
Who ever said there is no right or wrong, was wrong, there is correct and incorrect, their is also maybe, should of, could of, would of, would have and should have
Hell, the entire universe could be inside my mind alone and I could be slowly going crazy
The only thing I think is really important in areas like what we are discussing here is that you retain your earnest objectivity and be forever fair. Do not garner a bias, don't have preconceptions, attack each new piece of data on it's merit and enjoy the ride.
