Needs real discussions! I keep on seeing videos and posts about a flat earth. No one debates that because round earth adherrants view it as obsurd. Results in an echo chamber where flat-earthers get to appeal to extra-logical diatribes to get more people to believe them. "They won't debate us because they know we are right!"

A particle for gravity? Like a photon pushes matter, this would be the compliment. Instead of anti-photon they call it graviton?
