Crazy Idea – Is It Possible To Grab Time To Change Velocity?

I had a somewhat philosophical and for me out of the box idea. If we are going to get out in space we need to figure out how we can propel ourselves without using a lot of reaction mass. So I thought. The force we need then has to be similar to the F=ma equation. So then I made a guess from drawing a curve and then squeezing some time period. The acceleration had to be more than zero to get the effect. Otherwise the curve would just remain constant. With a small force from a space drive or some other device then I guess that the acceleration you get from that could then be multiplied by grabbing time. This means the drive need not produce such a large force itself but be safe.

So the idea is that you could amplify a small force or acceleration by grabbing time. How this is done I don’t know.
