I've been trying to come up with a theory for why the stars seem to stream past so rapidly at warp. I think this guy's got the answer:

STAR STREAKS: The phenomenon we see of streaks passing by when a ship is at warp.

A possible explanation is that we see stars passing by. However, this is disprovable: Some extreme speed we saw in TNG was 788,940c (I can't confirm the episode name).

This would give a characteristic angular speed for nearby stars of 1578 arcseconds per second or 1 degree every 2.3 seconds. This is indeed verified in simulations. Travel at high warp speeds, on the TNG warp scale, does not match very well the appearance of the bridge view screen on a typical episode. Indeed, most visible stars are not nearby but are further away with correspondingly lower angular speeds. I offer no solutions to this discrepancy other than the dramatic necessity that stars wooshing by at high warp speed.

There's a lot of support on rec.arts.startrek.tech for the notion that those things aren't really stars. For one, as the Enterprise drops out of warp (with the camera tagging along for the ride) some of the 'stars' do some pretty strange things, such as suddenly angling off in various directions, disappearing, etc.

Also, in 'First Contact', the Phoenix barely breaks warp 1 and stays relatively close to Earth, but we still see the streaks. Definitely not stars.

The predominant theory is that what we're seeing are free particles in space interacting with the expanding boundaries of the warp field. As they ross the warp field, they are repeatedly accelerated to FTL velocities and then slowed to STL speeds, and start spewing out something like Cerenkov radiation, a (real!) blueish light emitted when particles moving faster than the local speed of light (in a dense medium)are forced to slow down. If not exactly Cerenkov radiation, then something similar.

An other theory is that the streaks are part of the visual manifestation of Einsteinian space in subspace.

As a side note, in 'The Cage' (TOS), the moving particles seen through the forward viewscreen are explicitly identified as meteoroids.

The above came from the The Star Trek Encyclopedia of Technology and Physics page: http://www.treknology.8m.com/encyc.htm .

How much of this stuff is "canon" is somebody else's guess, but I favor the microscopic particle theory, myself. It makes sense. What other theories do we have for the "starstreak effect"?

There were no streaks in "Night", which I suggest might be related to there being no stars...

Baloo's idea has a lot of Merit. And perhaps that void was really a void of nothing.......

Well, I always assumed that they were some sort of subspace particles, but I suppose they could just-as-easily be normal-space particles that get pulled into subspace...

I think TPTB certainly intended them to be taken for stars. Although the idea of Cerenkov-like radiation from impacts in the subspace field is a nice idea, and makes more sense (at least most of the time).

I think Baloo has a good point about the "starstreaks". There are far too many of them too "close" to the ship to be stars, not only during the Phoenix warp flight.

What about the frequency and wavelength of incoming radiation during a warp flight? The external observer ouside the warp bubble as well as the internal observer inside would measure the same light speed c. The radiation, however should be shifted to blue or better x-ray, and the power of incoming radiation in flight direction should be much higher (Doppler effect). I think special relativistic considerations are not required, since the warp bubble is just a discontinuity apparently moving at superluminal speed, while the light speed is the same inside and outside. Is this correct or am I missing something?
