Spin Launch goes around in circles with Ka'u

[TomK]

What is your opinion based on?

Dont take my word on this high school physics question. Dr. Phil Mason did a couple of debunk videos on this.
Part 1. https://www.youtube.com/watch?v=9ziGI0i9VbE
Part 2. https://www.youtube.com/watch?v=ibSJ_yy96iE

I suggest you watch something that actually deals with the actual engineering and science rather than the nonsense in the videos you posted. The first video you posted a link started off with strawman arguments about using a countdown and a video with confetti so was a bad start. I forced myself to watch both but they were so misleading I feel sorry for anyone who believes the stuff that was posted in them. It was like watching a flat-earther post proof that the Earth is flat.

I suggest you watch this rather more sensible video and then reconsider your objection to the project and your view that suggests the engineers and scientists working on the project don't know more than high school physics.

PS. randomq - I now understand the 25% number. I was under the impression that SpinLaunch wouldn't launch things with rocket motors but that's not the case. What they want to do is replace the main rockets that are currently used by launching so fast that you only need a second or third-stage rocket.
