Indeed he is the same character, but Thor has many versions.
"Thor threw a hammer across a galaxy in less than 60 seconds?, your scan actually doesn't say that, it says it takes some time to return, he only needed to be separated from it for 60 seconds, which he said is more than enough time- this means it takes Mjonir MORE than 60 seconds. But even if he could, Broly destroys a galaxy in less than 60 seconds. "
If it was longer than 60 seconds he would have died in space.
At the time said event took place, Thor had a time limit of how long he could be seperated from his hammer and turn back into Blake, 60 seconds was that time limit.
So it was under 60 seconds.
That depends on what you mean, that is indeed the same character. Thor just jobs a bit more these days and isn't smacking around celestials all day.
"Pretty much. That isn't current Thor."
