I can't help but notice that the basic premise of this comic is very much like the reason for going back to 1970 in Avengers: Endgame, when they needed more Pym particles for time travel. I wonder if Randall re-watched it again recently? — KarMann (talk) 17:10, 17 June 2020 (UTC)

Drawing

There's one leg of the time-machine missing from the 3rd panel. (or is it the side of a base?) --162.158.155.126 19:57, 17 June 2020 (UTC)


Mined lead

Pb-210 (half-life 20.4 years) is a decay product of radon, and thus accumulates everywhere that is exposed to the atmosphere or where radon seeps from the ground. I suspect it could be a contaminant in lead from some lead mines, but wasn't able to find any references ShadwellNH (talk) 20:00, 17 June 2020 (UTC) Paul

One use only?

The way I understand it, the time machine is one-use unless you find other Low-Background Metal. If you find it, you can make more trips. It would appear that the trip is successful. --188.114.103.129 01:31, 18 June 2020 (UTC)
