黑洞的最小安全距離
我最近在去 Jaques Station 的路上遇到了我的第一個黑洞。我知道它即將到來，因為我特意選擇了它作為我旅程中一條腿的終點，但這並沒有讓我的到來更加令人毛骨悚然。
這是因為，從女巫空間出來後，當我檢查我的導航掃描器時，我發現我離它只有幾米遠。
在那一刻，我什至懶得轉身欣賞美景——我只是將我的主推進器指向它，然後將自己拖到至少十幾光秒外，然後停下來。
當我終於可以開始輕鬆呼吸時，我確實敢冒險靠近一點。但是，每當我的掃描器將測量單位從光秒更改為兆米時，我就會退出“星際雞”遊戲。（我認為通常是幾百毫米。）
當你靠近它時，黑洞的引力透鏡肯定會更加壯觀。所以我希望能夠更接近，觀察最大的效果。但是，知道黑洞的性質，這不是我想隨便冒險做的事情。（至少，當我在泡沫之外的數千里時不是。）
那麼，對於觀察黑洞，可以認為“安全”的最近距離是多少？如果這因黑洞的大小而異，有沒有辦法從掃描數據中得出它？我是否可以尋找其他跡象，以便在我違反安全限制之前知道我何時接近安全限制？
幸運（或不幸）取決於你的看法，Frontier 沒有準確地模擬黑洞行為。你可以像任何其他恆星物體（那不是恆星）一樣接近它並且非常好。
為了證明這一點，幾個 CMDR 飛過一個黑洞。
As Rapitor has noted in their answer, it is currently safe to approach most black holes even to the point of reaching the “Body Exclusion Zone” if they have one.
Personally, I’ve made this a bit of a hobby now. Whenever I find a black hole that’s in a place with an interesting view, I’ll go “faceplant” it and get as close as I can.
Different ships handle heat differently, so be mindful of your own ship’s tolerance for this. However, most black holes do not emanate much heat if any.
The process for approaching a black hole is rather simple, and similar to entering other unmarked locations of interest such as planetary rings without a Resource Extraction Site. Just approach it slowly, keeping an eye on your ship’s speed and heat levels. Make sure the ship isn’t accumulating heat faster than it can tolerate, and get your speed under 1 Mm/s before you’re forced out of Supercruise.
After the emergency drop from Supercruise though, is where black holes can get a little weird. Here, you run into one of two cases:
1. The black hole has a Body Exclusion Zone properly implemented.
You’ll be able to fly towards the black hole for a little while. Probably just a couple boost’s worth. Then, suddenly, your ship will stop moving towards it. Even with full throttle and boost, you won’t be able to get any closer and your HUD will show an alert “Body Exclusion Zone Hit”.
Most black holes I’ve encountered have this at around 20-40 km. However, there have been some with Body Exclusion Zones greater than 100 km. Then, there’s the rare and really big ones like at the Great Annihilator - I don’t particularly recall how big that one was when I got there, but I do remember it was bigger than any others I’d seen.
2. The black hole does not have a properly-implemented Body Exclusion Zone.
These are relatively few and far between, and the game developers may be working to fix them. For these black holes, either the Body Exclusion Zone just doesn’t exist or it doesn’t actually block ships from entering it - I’m not sure which.
What will happen with these, is what’s shown in the videos linked by Rapitor. You can effectively fly all the way through the center of these black holes, and the effects are rather spectacular.
IMPORTANT EXCEPTION - SAGITTARIUS A*
Do not attempt a faceplant at the Supermassive Black Hole!
My Asp Explorer generally runs pretty cool. I can typically get that ship out of a faceplant with any star or other object, without taking heat damage and without using heatsinks, and I can sit pretty deep in the corona of most stars for a good few minutes without substantial risk.
But for Sagittarius A*, faceplanting is not an option for that ship. As far out as 40 Ls, the heat levels began to rise rather quickly and I had to abort because I didn’t have the spare heatsinks to risk going further.
I might consider trying it again some time, if I build a ship that runs much cooler and packs a lot of heatsinks. If I do though, I will be going in with the full expectation that it is a suicide mission. (Though I’ll try to remember to change this answer if I survive!)
WARNING - GREAT ANNIHILATOR
Be careful here!
The black holes at Great Annihilator are absolutely amazing. There are few others like them in the galaxy, and their size makes for some rather spectacular visual effects - especially on your initial entry to the system.
I highly recommend a visit to Great Annihilator if you’re ever anywhere near it, but be careful if you want to attempt a faceplant at either of the black holes there. I personally have hit the Body Exclusion Zone on both, but I did notice that the space around them was a bit warmer than most other black holes I’ve encountered.
Mind your heat levels as you approach these, as you should for any stellar body - including other black holes. If you’ve got a ship that runs cool enough, you should be able to go in just fine. If your ship can’t take the heat though, get it out of the kitchen!
