Check it- I don't think realistically you can just travel in time like scifi movies portray, firstly because ok you got when in the universe you want to go, but 'where'? The earth has moved zillions of miles by now and if you're off by 6ft you've just buried yourself. So they use space ships and get you pretty close, and you go the rest of the way.
But also entropy says you can't create or remove energy, so when you come to the past, you don't bring your old physical particles, and you can't use up any already used particles already in existence. Hence your ghost like state.
Would explain all the UFO sightings and still no ayyys to date, but plenty of ghosts. The old cowboy costumes they wear is because history was copywrited by Disney in 2240 and the books are a little off by now. I mean 1,000 years from now they'll probably blanket this whole century as WW2 era customs just to make it easier. Your sweet custom Air Jordans will be lost to the sands of time, just like the cash in your wallet you used to buy them with.
