Black holes are not holes they are not gateways. They are simply matter that has collapsed on itself due to gravity finally overcoming the forces holding it apart. (I.E. Imagine the protons, nuetrons, electrons of each atom touching each other. Then every other atom touching the next with no space between)

The point at which the tidal forces become fatal depends on the size of the black hole. For the very large black hole this point will lie well inside the event horizon so the astronaut may cross the event horizon painlessly and live . Conversely, for the small black hole, those tidal effects may become fatal long before the astronaut reaches the event horizon.
smaller is no less deadly = fact
you are exactly right about it only matters when u get "close" to it....but obviously you cant help it if it comes closer to you!

No, they're not. Most people have the common misconception that black holes are the vacuums of the universe (I think Hollywood had a hand in this) but this is simply not true. A black hole only has as strong of a gravitational pull as the star had that first created it. Simply put, if the Sun suddenly turned into a black hole, which it won't don't worry, life as we know it would end yes, but for a different reason. Earth would keep merrilly circling the new black hole Sun, but it would be far too cold without the Sun's radiant energy to support life.
We have absolutley nothing to fear from them.
