Is it possible to change a screen name

Just wondering if it is.My youtube account is Heisenbubble as well as my name on another forum i use.Its really what i go by.Is it possible to switch my screen name to Heisenbubble without having to create a new account?

No you can’t just keep the name
If you make another account we have to remove this one
