Maybe the T-1000 was caked with the blood of 1000 rebels (think Arnold covering himself with mud in Predator).
Now a new variant has been made: A Russian and Japanese team has produced the first material made of two-dimensional fullerene layers that acts like a metal.
[...]
It should be possible to produce other materials in this class by varying the individual partners. The researchers expect that this will produce materials with exotic electronic properties, such as novel superconductors or spin liquids, which are materials that show an unusual magnetic state at absolute zero.
So he could have come back in time in a big pile of steaming ****...:lol
Dr. Silberman: Why didn't you bring any weapons, something more advanced? Don't you have, uh... ray guns? Show me a piece of future technology.
Kyle Reese: You go naked. Something about the field generated by a living organism. Nothing dead will go.
Dr. Silberman: Why?
Kyle Reese: I don't know! I didn't build the ****ing thing!
Dr. Silberman: Okay, okay. But this cyborg, if it's metal...
Kyle Reese: Surrounded by living tissue!
...why would the machines build a device that could only transport organic living objects?...
Nothing dead will go.
Well, that's sorta what the subsequent movies and tv series has done, but that just doesn't make any sense. Any change made and you'll risk important characters not meeting up or survive and you won't have any first movie.Ive always entertained the idea as well that the war started out of necessity for the machines to protect their existence from the Connors. The future can be postponed and altered to a degree but the outcome will always be the same.
Hair is dead tissue but goes through fine.
Cotton clothing would be organic covering. Dress a terminator in fruit of the loom from head to toe and he should be ready for time travel.
