Do you know that we can calculate our milky way galaxy's mass?
As you all know earth orbits the sun, so with this
M=V*r^2/G this formula can tell us our universe's mass.
Where M=mass enclosed by orbit(earth's mass)
V=orbiting velocity(earth's speed with direction)
r=average orbital separation(radius)
G=gravity
