The main principle is Bernoulli's theorem according to which pressure is inversely proportional to velocity. During storm the wind velocity is high outside the house than inside therefore the pressure is greater inside the house than outside. So the roof flies off as there is a force on the roof inside...

The main principle is Bernoulli's theorem according to which pressure is inversely proportional to velocity. During storm the wind velocity is high outside the house than inside therefore the pressure is greater inside the house than outside. So the roof flies off as there is a force on the roof inside the house due to the difference in pressure. read less

Why is only the speed of light constant in all frames of reference?

The only thing that affects the speed of light is the refractive index of the medium through which it moves, and for space, this number is 1.000000 and gives you the maximum possible speed of light.
