1. The problem statement, all variables and given/known data
In a star Trek episode, a space station orbiting a planet blows up. The chew of the Enterprise simultaneously hears and see the explosion; they realized that tehre is no chance for rescue. If you have been hired a consultant, what two physic errors would you have found and correct?

2. Relevant equations

3. The attempt at a solution
Since there is no gas in space, there should be no sound because sound can't travel if there is an absent in gas. ..... and i don't know the othre reason... can someone help me understand it?

which means that.. they can't simultaneously see and hear because sound wave (longitudinal wave)travels much slower than transverse wave...?

Yes, light travels faster that sound. So they couldn't see and hear the event at the same instant.
