Sunlight is way older than you think
It takes light a zippy 8 minutes to reach Earth from the surface of the Sun. But how long does it take that same light to travel from the Sun’s core to its surface? Oddly enough, the answer is many thousands of years. Sten Odenwald explains why by illustrating the random walk problem.

does that mean that the sun omitted no visable light for its first 170,000 years? Or did it start smaller than its current size?
