Can two ships collide while in hyperspace

32 posts in this topic

If the trajectory of two ships intersect is there a physical collision or does the entry into hyperspace place each ship in its own "Universe" so to speak.

If you watch the "making of" information in the movie "The One" it talks about how scientist theorize if wormholes exist or hyperspace travel exists, part of the "stretch" seen is that the space a wormhole would take up is incredibly small. Like smaller than an inch in size. So... While I assume it "could" happen, the odds are more likely you would get struck by lightning, while getting bitten by a shark, in the middle of a hurricane, and surviving.

 

The other theory is that you punch a hole between where you are and where you are going. In that scenario there isn't anything really in between.

 

Finally there is Star Trek where "warp speed" anyone can catch up if they can reach the same speed and collisions are just as possible as any other part of space.

 

I think you can pick and choose based on your story.

 

One thing about theoretical physics, is that nobody can really prove you wrong.

I was actually thinking about this earlier.

 

Keep in mind, there is nothing canon (or Legends as far as I am aware) to support this theory.

 

I would believe that we could assume that your matter, relative to the universe, would become stretched or thin.  This wouldn't make you impervious to external interaction, but would allow you to pass through things like small asteroids or other ships, as the case may be.  However, thin or not, you're not gonna get through a solar body.  There would be no room for your ship to pass through unscathed.  Planets or stars in your path would still kill you.

The different would be unnoticeable to the passengers, for whatever the reason may be.

 

What it really boils down to though is, those hyperspace lanes aren't like an interstate through South Dakota.  They are constantly packed, always holding traffic going both ways....  Eventually, two ships ARE going to pass through the same point in space at the same moment in time.  If it WERE dangerous, wouldn't it stand to reason that the on-board Navigation computer would detect another ship on an intercept course and make a slight adjustment in order to avoid collision?

Whatever excuse you come up with, it's still just plot.  If you want to come up with a reason to drop them out of hyperspace, it is just a Destiny Point away.  ^_^

This would probably be Legends now, but I thought there was an alien species detailed in the Ultimate Aliens Anthology (D20) that was from hyperspace? Maybe looking into that entry would shed some light as to the nature of hyperspace. :)

You can track something in hyperspace.  But space is so big that is would be nigh impossible to collide.  Even if you tried. look at the Rebel fleet how it launches.  They all stagger their jumps. is it because they are trying to avoid collisions? more then likely they want to avoid collision when the jump, and when they revert.

 

But for ships to collide at superluminal velocities?  If it were possible you would think there would be a lore more collisions since everyone has to stick to lanes

It's probably possible, albeit highly unlikely.  The gravitational shadows of objects in normal space, even ones as astronomically small as starships, will still trigger hyperdrive failsafes to prevent collisions (this specifically happens at least once in the New Jedi Order series, as well as being implied by the existence of low-tech interdiction techniques).

 

The hyperdrives of one or both ships would have to be extremely poorly-maintained (or sabotaged), and even then their courses plotted with extreme precision.  Shooting a bullet out of the sky with another bullet, basically.

 

But for ships to collide at superluminal velocities?  If it were possible you would think there would be a lore more collisions since everyone has to stick to lanes

 

How many ships are "lost to causes unknown"?  Given the energies involved, there wouldn't be any detectable debris, and it would be essentially impossible for a third party to observe.  And the alternative is that they cannot collide.  Given that objects in realspace (or at least their gravitational shadows) can affect ships in hyperspace, I'd expect that objects in hyperspace could affect each other too.

 

And there are examples of hyperlanes being interdicted by such low-tech methods as asteroids, as well as civilian shipping being cleared from them for mass fleet movements.  Space is big, and hyperspace travel fairly reliable if you maintain your equipment and stick to well-established routes, but that equipment and those routes exist for a reason.

Granted, you never "Really" get a great shot of it, but you do see the hyperspace tunnel, and honestly, just by the size of the tunnel, and the fact that we kind of follow Ackbar jumping in "last," I'd rule that no, there can't be collisions between craft in hyperspace. They don't appear to occupy the same space. Plus, consider this, they jumped in formation. This means that if one ship comes out a nanosecond LATE, they are almost guaranteed to ram right into the ship that jumped ahead of them and came out in the right spot. If this was a real possibility, you'd think military naval units like this would jump in a horizontal line to prevent this as an issue (instead of a vertical line like the fleet does).

Also, Legends speaks of the concept of Mass Shadows, and sensors on the ship drop it out of hyperspace prior to any sort of collision. Of course, some ballsy smugglers (like Han) turn these safety sensors off (or alter the settings), so that they can shave some of the safety margins off to travel faster routes that cut corners. Hence his extra caution in ANH, and Luke's/Obi-Wan's concern about why it was taking so dang long to calculate.

Obviously, at your table, you can run this sort of stuff however you like best. However, that is what the lore seems to have for us.

Considering that hyperspace lanes, gravity wells and failsafes are Legends now, you can pretty much decide for yourselves. 

 

If two ships in hyperspace get close to each other, it would be trivial for one or both to adjust their course slightly to avoid a collision. So I wouldn't think it would happen very often, if at all.

Hedge, that is assuming people actually FLY through hyperspace actively, which would open up human error at super high speed. Humans couldn't even podrace, but they could actively guide a ship through hyperspace? And what exactly are you doing with the navicomputer if you are steering anyway?

No, I think hyperspace is something that gets pre-programmed in, set, jumped, and the ride itself is wholly automated. Unless you are like Han, and destroy half the safety measures to coax more speed out.

I've never seen that as "has to" but as "prefers to". In that those lanes have been cleared of gravitational anomalies (rogue planets, dark matter, nonbaryonic gravitational sources, Hyperspace Dragons, etc).

I have an adventure planned where the groups will intercept a distress call from a Lane Clearer vessel and auto-drop out of hyperspace in the vicinity (which happens automatically to force passing vessels to render aid to these ships) and discover an ancient completely droid crewed vessel being besieged by Pirates seeking to steal it's technology, technology from a era almost lost to history.

You aren't flying the ship with a joystick, the navicomputer is doing the actual flying and collision avoidance.

You have to be able to explain how Obi Wan follows Jango in AotC. Obi Wan had to enter hyperspace without knowing Jango's final destination.

No its you go too close to a Mass shadow, or an Interdictor which generates a false mass shadow and the hyperdrive's safety system is supposed to drop you out a safe distance from the mass shadow because if your ship actually flies into the shadow it will badly damage or destroy the ship depending on what is generating he mass shadow.

 

Lets say there is a star generating a mass shadow at section B2. Your ship  is flying through hyperspace on a course that would take it from B9 to B1.Normally the ship's sensors will pick the mass up and the safety system will drop you out at B3 but some people disable those safeties. And if they fly into B2 while still in hyperspace very, very bad things will happen to their ship

Obi-wan Stuck a tracer beacon on Jango's ship after their fight. It is also possible that the beacon is able to determine the probability of a destination quickly, or do so through analytics crunched after the data is sent elsewhere (Jedi Temple), or by slicing the astrogation computer wirelessly? This would be similar to what Fett does to the Falcon, arriving at Cloud City BEFORE Han Solo does, to set a trap. Taking a vector and extrapolating a likely destination seems perfectly reasonable.

The other alternative here is that Obi-Wan jumps after him, and is making course corrections on the fly to follow Jango? That would create a situation that makes you question why the Falcon wasn't followed into hyperspace when leaving Tatooine by some sort of armed shuttle or gunboat with a hyperdrive, if they could simply jump after it. If that threat is real, why would the death star escapees on the falcon rest immediately once they jumped into hyperspace? Wouldn't they still have to be on guard? For that matter, why wouldn't Imperial's deploy tracking ships to follow the Rebel transports after Hoth?

For the Tantivie IV being followed by the Devastator, and Obi-wan following Jango.  Both had the aid of tracking devices.  There is nothing that says the beacons could work and transmit while in hyperspace.  Which would allow another ship to follow the beacon, but at a certain point you would know where they were headed, and just let the Navicomp take you the rest of the way and not worry about the beacon

 

For Boba Fett getting to Bespin, it think it had to be more of a case of "where is the falcon headed" and then since the Falcons main hyperdrive is out, it is easy to jump ahead and let vader know, and set up a trap.  Supposedly, by some accounts, it took The M.Falcon a few months to get to Bespin.  There is no frame of reference whether or not they went sublight, or used a backup hyperdrive

Isn't the Straw Wars Science: You are in hyperspace and go too close to a mass you drop out of hyperspace?

 

In TCW S1E4 a ship in hyperspace crashes right into a planet. Also, in S1E13, a ship enters hyperspace inside the atmosphere of a planet then later (their navicomputer was damaged) is about to crash into a star. The ship has to cut off all power to exit hyperspace. So, it appears to me that being dragged out of hyperspace due to a mass shadow has been retconned away. However, in that same episode, the ship was able to detect the star far in advanced of crashing into it, so should have been able to avoid it if their navicomputer was working. 

 

 

Taking a vector and extrapolating a likely destination seems perfectly reasonable.

 

Except Obi Wan exits hyperspace in the exact same spot that Jango did. He couldn't have predicted that. 

 

That would create a situation that makes you question why the Falcon wasn't followed into hyperspace when leaving Tatooine by some sort of armed shuttle or gunboat with a hyperdrive,

 

The Falcon was followed into hyperspace. However, since the Falcon didn't have a homing device on it, the Star Destroyers had to follow closely, allowing Han to realize he was being chased and evade/outrun them. Hence the line, "I told you I'd outrun them." 

 

if they could simply jump after it. If that threat is real, why would the death star escapees on the falcon rest immediately once they jumped into hyperspace? Wouldn't they still have to be on guard? For that matter, why wouldn't Imperial's deploy tracking ships to follow the Rebel transports after Hoth?

 

Leia knew they were being tracked yet still let them straight to the base. 

 

As far as Hoth goes, I don't think the transports went straight to the rendezvous (at least according to the Tie Fighter game :) ). However, any tracking ship would have had to been powerful enough to defeat the two X-Wings escorting the transport. If the X-Wings detected that they were being followed, they'd drop out of hyperspace and fight their pursuers.

Except the Tantive IV changed course while in hyperspace (radio drama episode 3). If the homing device didn't work in hyperspace, the Devastator would have ended up at the wrong place.
