声在介质中以光速传播的可能性
Possibility of Sound Propagation in Vacuums with the Speed of Light
摘要:
理论物理学的一个重要问题是声音是否能够在真空中传播,如果是这样的话,那么它必须导致对一个零静止质量粒子的重新解释,该粒子对应于真空-声波。以电子中微子为对应粒子,其观测到的不为零的静止能量可能只出现在中微子在物质介质中传播的情况下。这个想法也可能影响到致密物质的物理学,将真空和物质中的最大声速限制在光速之内。
英文摘要:
An important question of theoretical physics is whether sound is able to propagate in vacuums at all and if this is the case, then it must lead to the reinterpretation of one zero-restmass particle which corresponds to vacuum-sound waves. Taking the electron-neutrino as the corresponding particle, its observed non-vanishing rest-energy may only appear for neutrino-propagation inside material media. The idea may also influence the physics of dense matter, restricting the maximum speed of sound, both in vacuums and in matter to the speed of light.
