Question
How many particles are there in the universe?

Answer
Richard,

A LOT, that's how many...  I found one website which estimates, between 10 to the 72nd power, and 10 to the 87th power.

Expertise

I am not a professional astronomer by any means, but astronomy has been an interest of mine since childhood, and I am well-informed on the subject. If unable to answer someone`s question personally, I will know how to quickly find the answer online, because I keep myself informed about developments in the field and I know where to look for information.

Experience

I worked in an observatory for awhile at one point, doing various interesting things with a computer.
