# Why $PSPACE!=Dtime(2^n)$? [closed]

Why $$PSPACE != Dtime(2^n)$$? I can not see how padding argument can help here, how can it be proven?

• I don't understand. What is the factorial of PSPACE? – Jan Johannsen Oct 31 '18 at 9:45
• @Jan Johannsen - I assume that it represents the "not equal ≠ " sign in C programming language – Avi Tal Oct 31 '18 at 10:24
