Reality doesn't exist until we observe it.

[JuliaL]

Isn't this a bit solipsistic? The universe exist out of our  experiences. That's like saying color doesn't exist because I can't see.

I think I go back to Hume on this.
You can't show that color does exist without you, but you can act as if it does.  We all do.
There are other senses humans don't have; bees see ultraviolet, bats echolocate, sharks sense electromuscular activity.
At least we infer that they have these senses from their behavior. But there could be others as well.
How do we know how many other senses exist?
We don't.
So do they exist or not?
