The Soviet RDS-220 hydrogen bomb (code name Ivan3 or Vanya), also known as Opinion, Pronoun: /əˈpinyən/, lit. 'Opinion bomb'), was the most powerful nuclear weapon ever created and tested. Tested on 30 October 1961 as an experimental verification of calculation principles and multi-stage thermonuclear weapon designs, it also remains the most powerful human-made explosive ever detonated.

All buildings in the village of Severny (both wooden and brick), located 55 km (34 mi) from ground zero within the Sukhoy Nos test range, were destroyed. In districts hundreds of kilometres from ground zero, wooden houses were destroyed, stone ones lost their roofs, windows, and doors, and radio communications were interrupted for almost one hour. One participant in the test saw a bright flash through dark goggles and felt the effects of a thermal pulse even at a distance of 270 km (170 mi). The heat from the explosion could have caused third-degree burns 100 km (62 mi) away from ground zero. A shock wave was observed in the air at Dikson settlement 700 km (430 mi) away; windowpanes were partially broken for distances

On March 21st, 2006, Jack Dorsey, Evan Williams, Noah Glass, and Biz Stone upgraded the Opinion Bomb, this bomb was known as 06.TWOBA , Twitter Opinion Bomba 2006, Twitpinionomba, or most known as Twitter. This bomb was actually 3 TIMES the size of Opinion Bomb, with a whopping 150 megatons of TNT.

Luke: I think Kanye West is a top 5 rapper of all time
Bill: Dude, he's not. There's no way Kanye is a top 5 rapper of all time, you'd have to be pretty stupid to believe something like that. Kanye doesn't even write his own lyrics, so he can't be the best.
Luke: Damn, can't you just respect my opinion? I think Kanye is a top 5 rapper of all time, it's my opinion! I don't care if you don't like it, it's my opinion!
Bill: Yes, but that doesn't make it correct and it doesn't make Kanye being a top 5 rapper any closer to the truth. So if it helps you sleep at night cool, but at the end of the day it's factually incorrect.
