Near an event horizon wouldn't be much of a problem, as long as you're moving quickly enough and on a path that would take you across it as opposed to into it. You would simply slingshot around. (Of course, it depends on how near is near). Within the event horizon - now you're in trouble.

If the black hole is a Scharzschild Black hole, yes. However, we must note there are multiple event horizons for complex (IE real) blackholes. And being close to the static limit already means you're bathed in the plasma caught near said event horizon.

Also, we have not considered the impact of a Kerr black hole on a nearby planetary body.

Despite conventional wisdom, black holes do generate a magnetic field...

I can't find numerics on field strength, but that would also fuck with any form of life given a sufficiently strong magnetic field. And then we keep forgetting all the charged particles, flying around the black hole. I'm certain a new planet would love to have it's atmosphere eroded away!

Just another G-C can't fucking do anything right, even as simple as Google search, scenario.

Stupid child thinks "black hole" means "Applied Phlebotinum"

Actually, near the event horizon of any reasonably sized black hole would be a trememdous problem because of tidal effect. The difference between the force the blackhole exert on one end of you would be different from the the force excerted by the same black hole on the other side of you by many more orders of magnitude than the force required to split you into tiny red wiggling morsels.

Penetrate into event horizon? You will never get there. The definition of even horizon is the point where an object falling into the blackhole from a grant distance would attain speed of light under balck hole's gravitational pull. By relativity, time will slow down to dead stop as you get there. To an external observer you will come to rest smeared all over the even horizon, but you will never get in, unless you somehow bleed away a huge amount of your kenetic energy as you fall. They only way we know how that could happen is if you transfer that energy by friction. This is why things only enter black hole through accretion disks which radiates away the kenetic energy as gamma rays.

You will never survive the gamma ray.

Either way, where you are close enough for black holes to distort time or deflect sun light, that will be the place you die.

All hence my "how near is near" caveat. If you've wandered into the Roche limit of the object then good luck to you. Still, points taken. This is what makes the internet a wonderful tool for education, when used responsibly and critically.

Regardless, it shows just how much more wonderful is the real Universe than any superstitious dogma.

"I have no doubt that in reality the future will be vastly more surprising than anything I can imagine. Now my own suspicion is that the Universe is not only queerer than we suppose, but queerer than we can suppose."
-- J B S Haldane (though often misattributed to Sir Arthur Eddington)

"In some respects, science has far surpassed religion in delivering awe. How is it that hardly any major religion has looked at science and concluded, 'This is better than we thought! The Universe is much bigger than our prophets said, grander, more subtle, more elegant. God must be even greater than we dreamed'? Instead they say, 'No, no, no! My god is a little god, and I want him to stay that way'"
-- Carl Sagan

This picture shows the size of a sphere that would contain all of Earth's water in comparison to the size of the Earth. The blue sphere sitting on the United States, reaching from about Salt Lake City, Utah to Topeka, Kansas, has a diameter of about 860 miles (about 1,385 kilometers) , with a volume of about 332,500,000 cubic miles (1,386,000,000 cubic kilometers). The sphere includes all the water in the oceans, seas, ice caps, lakes and rivers as well as groundwater, atmospheric water, and even the water in you, your dog, and your tomato plant..."

Tell me again about all that water that shot out of the ground, xtian. Still dying to know where it all went.

I sense another "miracle" coming.

You can't have the water in either my dog or my tomato plant chick!

Mine you're welcome to....

According to Conservapedia's centrefold boy NephilimFree, a lot of it hit the Moon and made all the craters. Seriously, he's gone on record as saying we'll find fossils of fish and shrimp and whatnot there.

That's probably the dumbest thing I've ever heard.

Providing that I haven't bungled the math, with the earth having a surface area of ~510 km^3, that means there's enough water (from all terrestrial sources) to cover the entire surface area of the earth to a depth of about 2700 meters.

That's assuming of course, that the surface of the earth is uniformly at sea level. Which it isn't - 71% of the planet is covered by oceans with an average depth of ~3900 meters.

There isn't anywhere near enough water on earth to get the job done.

Cue the ad hoc explanations in 1.... 2..... 3.....

I absolutely agree. That said, though, if I've learned only one thing it's that just when you think you've come across the dumbest thing ever, along comes something even dumber. We are never safe...
