Went 24.6 Km from a Black Hole, got a Body Exclusion Zone Hit and couldn't go no further

CMDR AKIRA MASAKARI · Apr 10, 2015

Yesterday night i went to the Pleaydes Nebula, in the MAIA system, very close to civilized bubble. In there there's MAIA B, a 25km Black Hole that is at about 350000 Ls from the Star, so i got some speed.

Then, i ended up bumping in MAIA B, was thrown out of supercruise, and the Black hole was about 250Km away but i got no heat dmg.

To this point, i decided to normal cruise toward it, but when i reached 24,6Km distance i got this message "Body Exclusion Zone Hit", and couldn't go further even at full throttle (i even try to boost).

But nothing, that was the limit

I was basically inside the lenticular effect, and many stars look cluttered.

Since the MAIA sytem is inside Pleyades Nebula, you normally have a nice orange\greenish background, but being inside MAIA B lenticular effect, thos colors and clouds looked distorded from normal cruise mode (so no acceleration FSD effect).

And this is how the Black Hole looks without UI on it from 25km, veri different from a plain black dot you see in the distance.

I bet meny of you already experienced that, I'm not pretending to be first one, just wanted to share the amazing experiece!!!

That exclusion zone was added so you couldn't simply pass through planets and other objects like you could in earlier versions.

Stars will destroy your ship via heat before you get close enough for any of this to matter, but black holes seem strangely harmless...this should probably be changed.

You just have to try to approach it from different angles.

You need a light source in the right direction to get the lensing started.

New real world scientific discoveries tend to imply they are less dangerous than what we imagined.
It seems the Event Horizon does not exist, and in fact recently a binary star system went through the event horizon of Saggitarius A, but emerged fused as one, and the monster did not devour it. We really don't know a thing about black holes, I'm fine with Frontier interpretation that could even possibly be "realistic". OFC radiations and gravitational tides could reap our ship apart, but it ould hppn also going that close to any star, so i buy this compromise between gameplay and """"""realism""""""".

It was amazing and scary, with crazy visuals that could even make sense.

WOW!!!! beautifull pic congratulations!!! Can i ask you how you link pics like that in the forum? I mean, almost full size?

Could you possibly find the info on the binary passing through Sagittarius A* I've looked but didn't see anything and would love to read that. Is that that what made S2?

Also excellent pic, I love the Black holes in this game and neutrons still scare the bejeezus outta me

On yopic about the exclusion zones though and the no damage. I think it would be cool to have pressure build up (maybe with a readout) until the ship says "warning pressure critical"

Add in some more stress sound effects and you'd have a wonderful scary experience going. Just my 2 pence

I hope real-life black holes are more interesting than a faded coffee stain on my desk.

In the real world approaching a black hole would simply completely torn apart your ship through sudden and strong gravitational distortions,the way it is now is wrong and that should be changed so that if you approach a black hole the heat will just start damaging your ship badly and quickly, that's the simplest way to implement it

It's not so much sudden distorsions as the insane tidal effects. The gravitational force is so strong that changes in the gravitational field even over small distances are huge.

For example, in orbit around Earth at 25km (the same distance the OP was from the black hole), the gravitational acceleration is 9.726517132338916 ms^-2 (using this for calulations), which on a 100 ton starship is a force of ~972652N. This is the force required to curve the ship around the planet so it stays in orbit.

Now, let's consider each wing individually. Say on something of a similar size and shape of a Cobra Mk3, each wing (along with all the gubbins inside) has a mass of 30 tons each and are 10m apart, and the ship is orbiting at 25km with the wings oriented 'up/down' relative to the earth.

At 25km minus ten metres, the acceleration on the lower wing is 9.72654750404824ms^-2, which corresponds to a force of ~291796.6N. The upper wing undergoes the acceleration we worked out above, so a force of ~291795.5N. Our spacehip will experience a force of roughly 1N pulling its wingtips apart due to gravitational tidal forces. This is due to one wingtip being slightly closer to the planet, but both being forced to travel at the same orbital speed (as they are joined together).

Now, what happens if we are 25km away from a black hole? Say one with 20 solar masses, as might be produced by a big supernova.

Plugging things into the magical site that is Wolfram Alpha, we get an acceleration of 4.247 * 10^12 ms^2 giving a force at the upper wingtip of ~1.27410*10^17N. That's roughly 127 thousand billion newtons of force.

At 25km minus 10 metres, we get 4.25*10^12ms^-2 giving a force of ~1.275*10^17 newtons. A difference of 9*10^13 newtons.

Gravitational tidal forces would be pulling the wings apart with a force of roughly 90 billion newtons, simply due to the difference in gravitational pull from one wingtip being 10 metres closer than the other.

Incidentally, it's this tidal force which causes Jupiter's moon Io to be volcanically active, and which keeps the subsurface oceans on Europa and Ganymede liquid.
