Earth The Size Of A Tennis Ball

[Photon Guy]

If the Earth was the size of a tennis ball, this video explains the size and scale of the universe. This video will make you feel very small.

You'll feel how small and insignificant you're in 3,2,1....

But seriously, this approach is the best to understand the actual size of the Universe. I've read the scientific data and watched lots of similar videos but only this one made me understand everything. Thank you for sharing this.

I visualise the observable universe size - 96BLYRS - this way: if the diameter of our galaxy is 1mm, the universe is 960m across.

Just note that UY Scuti is no longer considered the largest star. Turns out it's much closer to us than originally thought so the calculations of diameter were inaccurate... It's still ginormous, just not the most ginormous.
