It's very easy to go to Europe or anywhere else without money, all you have to do is sit at home and use your imagination. Trust me, I've done it a couple of times. It's fast and it costs nothing but if you have no imagination then that'll be a problem.
But on a serious note, you can't even get groceries without money. So why would you think you can travel without money. It's impossible unless you get someone to sponsor your trip but however it is, someone would definitely have to pay the cost of your trip.
