Physical time travel and invisibility is the definitive of what happened in the manga. They observed Grisha without anybody detecting them(invisibility) and they went back in time to do so(time travel). Now, intangibility is something that the community came up with, some saying that Grisha is only pretending to hug Zeke. This is ridiculous, as he is hanging his arm on Zeke’s shoulder. This by itself has yet to be proven, but there is an argument to be made that Ymir passed through Eren Yeager’s body.
