DCEU Speed Upgrade: MHS+ to Sub-Relativistic

It seems like no calc group member has made a new version of the calculation yet.
 
Angsizing shouldn't be used here as it yields results that are impossible. A satellite this close to Earth would be pulled back in due to friction heating it up and making it gradually lose its momentum.
 
You don't need to go very far up to see some curvature.

Angsizing yields 44km for that pix. The screen height there also needs to be substantially below 100 kilometers since the Karman line isn't visible in it.
 
Also, the low end isn't a low end. A better low end would be 360km, which is the distance that cheap ISS satellites are currently orbiting at.

So, for a true low end, use 360km. Which nulls the 2nd feat.

Now, the Cyborg one depends on whether the starting assumption (Superman has SoL heat vision) is true or not.
 
Superman's lightspeed heat vision was accepred in a different thread cause it showed properties of light
 
I am not able to be of much help here. Sorry.
