Is the CMB radiation left over energy from the battle between matter and anti-matter?

For ease of use, wouldn’t these calculations be better place in an Excel spreadsheet, or some other math program?

Think I’ve figured out how Wikipedia got 365.256363004 SI days for the Sidereal year? Earths semi-major axis a = 1.4959974465490E+11 Metres. Gravitational constant G = 6.67408E-11 Newton Metres squared / kilogram square Suns mass M1 = 1.98855E+30kg Earths mass M2 = 5.97237E+24kg T =...

I doubt that you will be able to find a modern world map of skin colour distribution.

Do you have a link?

It depends on how accurate the data is. According to that site I’ve been using, Aphelion, Earths closes approach to the Sun will occur in 62.612 SI days on July 4th 16 hours 24 minutes UT. What way could that be proved? Sorry I meant, Earth will be furthest away from the Sun. Note to self...

I’m trying to find the average anomalistic year and the average tropical year. Maybe I need more than 25 years? Does anyone know of a data source that I can use?

Wikipedia average Anomalistic year is 365.259636 days, but using that site again. Perihelion Perihelion Anomalistic year 2000 Jan 3rd 5 hours 18 minutes- 2001 Jan 4th 8 hours 52 minutes 367.1486111 days 2001 Jan 4th 8 hours...

Using that site again to count the days from 2000 December 21st 13 hours 37 minutes to 2025 December 21st 15 hours 3 minutes (winter solstice to winter solstice), Totalled 9131.05722224 SI days, divided by 25 years is 365.24239 SI days per year, minus the average tropical year of 365.24219 days...

Using that site again to count the days from 2000 June 21st 1 hour 48 minutes to 2025 June 21st 2 hours 42 minutes (summer solstice to summer solstice). Totalled 9131.0375 SI days, divided by 25 years is 365.24150 SI days per year, minus this value from the average Tropical year of 365.24219...

Never ceases to amaze me how complex our climate is.

Using that site again to find the average Tropical year from 2000 March 20th 7 hours 35 minutes to 2025 March 20th 9 hours 1 minute, I got 9131.0597222224 SI days. Dividing by 25 years; the average tropical year from 2000 to 2025 is 365.24238888890 SI days. Wikipedia value for the average...
