Good morning everyone! Firstly I would like to ask a question. Do you think how much influence an object which is less than one kilogram can produce? Maybe you will say its influence could be ignored, but sometimes, something weak could break out huge powers in certain circumstance, such as the skeleton brand effect. 1kg card could push 2kg card, and then 2kg card could push 3kg card, and continue, it will push goods of ten million tons. For another example, a bird hits a plane which is flying at the speed more than 900 kilometers per hour, it may make hundreds of tons of large aircraft crashed. Because the power of this crash is equal to a shell. And for example of the atomic bomb, its warhead and the projectile is only 20 metres long, but it can destroy a small country. As a result, we cannot despise any weak ones, maybe sometimes they will eliminate countless huge ones.
