What do dropped mobile phone calls, mysterious signals in undersea communications cables, and tiny tremors on the Earth have in common? They are all caused by vibrations on the Sun, according to one team of scientists. But other researchers question the claim, arguing that the pulsations may never escape the Sun's surface in the first place.

Churning motions inside the Sun produce various kinds of waves, including sound waves called p-modes and another type of wave called g-modes. G-modes arise when pockets of material rising up from deep within the Sun get pulled downwards again by gravity, leading to a wave motion similar to the rise and fall of waves on the surface of the ocean...
