# How big is the universe?

There is (10,000,000,000,000,000) seconds since the Big Bang. If light travels (186,282) miles per second and there is (31,557,600) seconds in year, then I multiply (186,282) per the amount of seconds in a year (31,557,600) which equals (5,878,612,843,200) miles a year.

I multiply the amount (5,878,612,843,200) miles light travels in a year to the distance of an average size galaxie (150,000) light years across which equals (881,791,926,480,000,000) miles across. To account for the space between galaxies I will multiply (881,791,926,480,000,000) the size of an average galaxie times 40 which is (352,716,770,592,000,000,000) miles from each other. Now I will multipy the total miles (352,716,770,592,000,000,000) between galaxies times the seconds since the Big Bang.

The galaxie is (3,527,167,705,920,000,000,000,000,000,000,000,000) miles across and there has been (10,000,000,000,000,000) seconds since the Big Bang. Light travels faster than time. I spent all day on this...

ok, was looking at the picture above and I accounted the seconds, but measured how far it light traveled only one way. I have to account for the other way light travels, so I take the total amount of (3,527,167,705,920,000,000,000,000,000,000,000,000) miles across and multiply that by 2 and the answer is (7,054,335,411,840,000,000,000,000,000,000,000,000) miles across.

The universe is (7,054,335,411,840,000,000,000,000,000,000,000,000) miles across.

• Don't forget about dark matter which we have no idea about any of it other than it is something and it makes up the majority of the universe. For all we know dark matter can travel faster than light.

It's scary how little we know about the universe...
