How would interdiction of Spaceships be possible? (feddit.de)

Hello Sci-fi fans and writers, I hope that this here is the correct spot to ask this question regarding a conundrum I have come about during my work on a sci-fi short Story.

Outline

In said Short Story, I have some people (Agents) chasing after some other people (Heroes). The heroes stumbled upon some critical information that could damage the faction (Bad Guy) that employs the chasing party. The information got intercepted in time, but to make sure that the information wouldn't be leaked again, they would need to silence the heroes.

Technology

In space there are two modes of flight: conventional reaction based propulsion and a higher speed propulsion which uses a so-called jump drive which flings the spaceship along a predetermined trajectory at high sub-light speeds (max speeds would be 0.5c). There is near instantaneous communications, but you would need to be in coverage of the network itself, which is flaky at best.

Conundrum

So how would agents be able to intercept / interdict the heroes in a plausible fashion? Would it be reasonable to have a micro wormhole generator or some other way to deploy gravimetric wells, which would destabilize the entire star system? Would it be anticlimactic to just have the agents wait for the heroes to finish their jump, as they would know where they would drop out?

I would love to hear opinions and suggestions from you.

This is the sort of thing I would ask @nyrath about. I don't know if a mention like that can summon him.

I love to think of fanciful physics for astronautics, and I think audiences like it best when the system is self-consistent. It's very hard to design systems that don't lead to contradictions or paradoxes. In a way I think it's like designing a playable game.

@swope @DmMacniel
Alas, I am not on Lemmy, so I never saw the original post.

In this case, I again note that the important thing is to focus on Effects, not Causes.

The desired Effect is "intercept / interdict the heroes".
The proposed Cause of "deploy gravimetric wells" seems to have too many unintended consequences. For starters it can destroy planets.

Perhaps some technobabble that slows down the protagonist's ship engine?

@nyrath @swope @DmMacniel
Seems to me, rather than trying to come up with elaborate trapping mechanisms, maybe set some limits on the jump drive itself. Like:

* It is difficult to hide vehicle's jump trajectory.
* Once in jump, a course is locked, can't be changed (or not without consequence like burning out the drive).
* Observers can easily determine the endpoint of a jump and notify local authorities to intercept.
* Recuperation is needed before next jump.

My previous ideas about the jump drive is the following:

It needs time to spool up. And you need to be at a certain velocity, achievable via Main Engines, before the Jump Drive can engage.
The Jump Drive takes over Main Engines, so no steering mid-flight even to the slightest degree (Perhaps this could be overridden)
It is On Rail, e.g. you can't change trajectory mid-flight and would need to shut the drive off prematurely
The Jump Drive needs to "cool down" before being used again.

Additional Ideas would be:

As the Jump Drive allows the Ship to travel at sublight speeds, it would still be detectable and observed from the outside.
The Ship is still in normal space.
