Is the distance factor missing a square root? Never mind….it’s already in the base, since the magnitude,scale is 100^(dm/5).

That is a strunk and white violation.

He has the formula at the star of the video. 5-6 is the limit, so say dm=30, so 1 million AU….which is 8.3 X 60 million light seconds, divide by pi.e7 s/year… 16 ly…. Hmmm, seems low.

@fromnorway643 but you’re not using Scott’s formula.

@codymoe4986 the whole point of plaid is that it’s faster than ludicrous, which is where the stars are zipping by.

And a 12 gauge hurts more than a 20. 🤷

If you multiple magnitudes by 100, it’s exactly cB (centibel). SI has a base unit, candela, which is superior to irradiance (W/m2).

Gaia?

@andreaperv9989 but T sqaured goes as R cubed, so for 200 AU, that is a thousand year mission.

Break out the jansky’s.

It’s the same factor.

I think a mid photon is half eV, so one watt means 2 / 1.6e-19 per second. L 🌞 is 4e26 w, so in the 1e35 photons per second range.

What is the minimum safe distance to stare at the 🌞 😎?
