Which CTs actually reach sub-Light or Light speed?"
Disclaimer: This is just a curious question. We know that Dabura tries to achieve light speed with physicality. But he has light-based CTs and attacks. So, how many characters' attacks reach light speed? Here are a few candidates, and I picked CT attacks which I think reach light speed. You can choose overall like Gojo's Red, Kashimo's attacks, Yuta, and Sukuna. Also, I choose Modulo Yuji's BM because, based on a calculation of his output, efficiency, power, and control, it allows him to perform a BM at light speed. This is just a theory and my calculations; if someone disagrees with it, then explain! So, who gets light speed?
