How far has our first radio signals reached out in universe?

Better make that Galaxy. Remember...radio signals travel the speed of light. The vastness of the universe is beyond comprehension...

Amazingly, in that tiny volume of space there are probably over 10,000 stars.

The vastness of space is almost without comprehension. For example, in the picture above we're looking at the Milky Way Galaxy. The Milky Way is comprised of around 100 billion stars. Now..,scientist estimate there are around 100 billion galaxies. To give you an idea of the magnitude of our visible universe, imagine a penny is our Milky Way Galaxy. The Milky Way Galaxy is 100,000 light years across. So with a penny for scale, the edge of the visible universe would be between 15-20 miles away.

Hard to believe if you get far enough out in one of the "fingers" you can hear repeats of Brent Musburger saying "You are looking live at ..."
