PPT-Watching Galaxies Form Near the Beginning of Time

The Cosmic Time Machine Astronomical telescopes cant help viewing the past Distance and time are always mixed in astronomical observations The finite speed of light means that we always see things after they have happeneda delay of 8 minutes for the Sun and about 12 billion years for the most distant galaxies we can observe In other words.
