Me and my friend were messing around with a ball we made. The bouncy ball was slightly modified so that it gained speed every time it bounced. We used jinto’s physics mod to increase the maximum veocity to 9999999999999. We had a radio, gps, and speedometer parented to the ball. We had an instrument panel that showed position, speed, and max speed. The speeds we got where 43770985.455 MPH, 7044240220.19 KPH, and 77036847104 as the velocity. We believe that to be the highest reached in source. If the admin Snake is on the server, he can show any non believers. Here is the IP for the server
The ball dissappeared once it got to high speeds, but after a few trials this is the fastest we got.
