Hello: I have another distance astronomy question for you. You helped me with another question which I appreciate. I just cannot do the math required.

There is a realm of the richest galaxies in the in the night sky. They are 50 million light years away. That is 6 trillion x 50 million???. What math equivalent is that??.I used 6 trillion as a L/Y last time. Thank you.

Hi Roly,

Fifty million is 50,000,000. Six trillion is 6,000,000,000,000. Thus

6 trillion 50 million = 6,000,000,000,000 50,000,000

6 5 = 30 and there are 19 zeros so this is

30 10,000,000,000,000,000,000

In Billions and More! I see that 1 followed by 18 zeros is a quintillion so

30 10,000,000,000,000,000,000
= 300 1,000,000,000,000,000,000

is 300 quintillion.
