Let me try again. The light ring is a reflection off of gas that lies
between the earth and the supernova.
light travels / \then reflects back to earth
to dust / \
star----light travels to earth directly-------->earth
The distance from the star to the earth is 169,000 light years. The
diameter of the ring is 400 light years, giving a 200 lightyear radius.
Pythagorean theorem tells us that the travel path of the light from the
star to the dust then to the earth is
a / | \ b
/ 200 \
/ | \
to find the travel distance for side a we have
a=sqrt[(169000/2)^2 +(200)^2] =84500.2366
b=sqrt[(169000/2)^2 +(200)^2] =84500.2366
The total travel path from the star to the dust to the earth is:
169,000.47 lightyers compared with the 169,000 lightyears direct distance.
With the ring as I drew it, the reflected light from the ring should get
here about 6 months after the light from the initial explosion.
The inner ring is at the star, not at the dust.
Does this help?
