neil degrasse tyson listening to walking on sunshine: haha this song is great, but unfortunately you can’t walk on sunshine. its too hot!!
actually the reason you couldn’t walk on the sun’s surface is because it’s not dense enough. the surface is actually only about 7000 degrees - hot enough to burn you up very quickly, but in a heat-resistant suit you could last for a little while, long enough to take a few steps at least
but unfortunately you would fall right through the surface and quickly fall towards the center
