"The 13.7 billion years is the currently measured time to the Big Bang and 379,000 years is the number of years after the Big Bang when the universe cooled off enough to become transparent. The mostly visible light photons from the hot plasma that filled the universe at that time have been traveling since then and have now been red-shifted down into the microwave range. This is the Cosmic Microwave Background radiation that has been very accurately measured by the WMAP satellite. We will not be able to see back further in time with photons since the universe was opaque to photons before that time. It's theoretically possible to see back to 10^-30 seconds after the Big Bang IF we could measure the possible gravitational waves that could have been generated at the end of the inflationary period of the Big Bang at that time." --Frank Heile

I think that image is from Nosferatu (1922) by F. W. Murnau -- only 90 years ago, which seems like a very long time ago :-)
