# Zias and B.Lou's Sound Faster Than Light Test A clip of streamers Zias and B.Lou trying to prove sound might be faster than light by flicking on a phone flashlight while yelling 'Ah' went viral on TikTok in 2025 and blew up again in September 2026 as an ironic 'great scientists' meme. ## Origin The test happened during a ZIAS! YouTube livestream on March 22nd, 2025, at roughly the 1:51:24 mark, when Zias read a chat message asking whether sound is faster than light and decided to run the experiment on the spot[1]. He turned on his phone flashlight at the same moment he made the 'Ah' noise, and B.Lou called it live, giving the win to sound[2]. The clip is credited to the streamers' ongoing 'Hood Research Department' series, which frames goofy on-stream experiments as legitimate science[2]. Zias and B.Lou created the moment themselves; no separate editor is credited with the original format. - **Platform:** YouTube (stream origin) / TikTok (viral spread) - **Creator:** Zias and B.Lou - **Date:** 2025 ## Overview Zias and B.Lou's Sound Faster Than Light Test is a viral clip from a March 2025 ZIAS! livestream where the two streamers try to settle a chat question about physics by flicking on a phone flashlight at the same moment one of them shouts 'Ah,' then judging by feel which one arrived first[1]. B.Lou rules that sound wins 'sometimes,' even though light is objectively faster, and the deadpan confidence of the ruling is the whole joke[2]. The bit lives inside the pair's recurring 'Hood Research Department' segment, in which they test scientific ideas with visibly unscientific methods[2]. Edits that spread in September 2026 lean into that framing by treating Zias and B.Lou as serious researchers, pairing the flashlight clip with orchestral music, lab b-roll, and captions calling them geniuses[3][4]. ## Frequently Asked Questions ### What is Zias and B.Lou's Sound Faster Than Light Test?
