Thanks for your comment.

Elena and Isolde are real names. This is how the experimental platforms are called in reality.

Antimatter is indistinguishable from the normal matter, of which we are made, the only difference is in its opposite electrical charge

Antimatter is similar to matter, but it can be distinguished. Different properties means different handles for observing something and get what it is.

The rest of your comment is correct.

Ahaha! Good luck. I won't give you the answer :D
