Distance between earch and the echo of the Tycho Supernova

[ragarth]

Is there a known distance between Earth and the dust/gas that the light was reflected from for the supernova of SN 1572 (Tycho's supernova)? I need this calculation to be made without adding the distance to SN 1572 to the time between Tycho's observation and now.

Also, what's the angle between SN 1572 and the echo remnant? Found this one, 3.15 degrees

This information would be useful in a debate between myself and someone else, the idea is that if the speed of light has varied within the passed 6,000 years, then the distance between SN 1572 and the deflection point for the echo would be something other than 452 light years.

Unfortunately, it is not possible to calculate the exact distance between Earth and the dust/gas that the light was reflected from for the supernova of SN 1572 (Tycho's supernova) without adding the distance to SN 1572 to the time between Tycho's observation and now. This is because the speed of light can vary depending on the medium it is travelling through, and we cannot assume an exact constant speed. Furthermore, the exact distance is also affected by the curvature of space-time, which varies with time and location.However, the approximate distance between Earth and the dust/gas that the light was reflected from for the supernova of SN 1572 is estimated to be around 452 light years. This estimate is based on the assumption that the speed of light has been constant over the past 6,000 years, and takes into account the curvature of space-time. The angle between SN 1572 and the echo remnant is 3.15 degrees.
