Do you know whay albert einstein got a nobel??? Because he found Photoelectrocity. Do you know what is this?? it mean that light wave can be a particel. Albert einstein tried in his experiment. he took an unstable atom. Then he gave wave light intensity. when he give it small intensity, it become more unstable. but when he increase the intensity, it (atom) becomed stable. So it mean that wave light can become a particel (material). all of us know that wave light is invisible. and from this text, we know that wave light is particel, and particel is wave light. so, all of thing (particel) is invisible. and all of you maybe invisible.
Now, the homework all of us is how to make particel become wave light. so we can move like a wave light (300.000 km/s). wuuuzzzzz!!!!! So we can go to other planet or maybe other galaxy. Nothing is immpossible!!!
