Scala, Java, C++, C#, Ada etc are all Turing Complete (http://en.wikipedia.org/wiki/Turing_completeness) languages so from a computer science point-of-view they can all achieve the same results. I can write an assembler equivalent of anything you write in Scala. To quote the above linked wikipedia however; "Obviously, this says nothing about the effort needed to write the program" ;-) For the ultimate example see: http://en.wikipedia.org/wiki/Whitespace_(programming_language)
You might want to take a step back and think about *why* you wish to learn a new system, language, framework.
If you're doing this as a hobby then you can go crazy and pick the most interesting thing you can find. If you're doing this to improve your job prospects then the best thing to learn will be whatever potential employers are looking for. If you're starting you own company then you might worry about productivity or your ability to recruit other developers (unlikely if you choose whitespace). You might be worried about speed of execution, integration with other systems or even whether you can formally prove your code is correct.
If you ask questions as open as the one you have asked then you'll always get suggestions for things that are very cool but new or obscure. Is this what you're after?

And no, Scala isn't "as powerful" as Java, the language didn't wish to stoop that low.It's a great deal more powerful.
