: : According to universal theory Big bang happened 20 billion years ago. : : Galaxy far way from these have been found. : : Also what about Sound frequencies after the blast they t ravel far slower then light. : : we should be also able to catch those.Any takers.

: Your information concerning galaxy ages versus big bang age is incorrect. Sound requires a : material medium. One elementary science experiment I remember (from 9th grade?) was a noise source inside an inverted glass bowl with a vacuum pump - once the air was pumped out, you couldn't here the noise, although it kept clapping. : :

I cannot accept that sound frequencies cannot travel space and light can. Can anybody explain.
