Question, with video example link, about preventing particles from floating up

[Indigo_Wraith]

I am creating an explosion effect in space. I nearly have what I want, but I can’t figure out how to keep the particles that fly from the blast from slowly floating up. I want the particles to move by the camera in slow motion and in a straight line. What do I need to do? Here’s the video example:

Thanks for any help.

After exeperimenting I have found that turning the Constant Acceleration down to a low number on the Z axis, I get the desired effect.

Here is the effect I was trying to reach. I’m going to edit this particle generator further, but it’s looking okay so far:
