Event Description 

The rumbling of thunder is not due to echoing off nearby buildings but rather occurs because of a strange property of waves in two-dimensional space. Is it possible to stop thunder from rumbling? Yes! All we need to do is to have an additional time dimension, and amazingly, beautiful experiments are being done right now that simulate a space of two time dimensions.
