Building a Mirror World

Chirality is the phenomena where a molecule can have the same number of atoms, but be aligned in a mirror image of itself. This has effects on how the molecule can be used and turned into amino acids. The easiest example of chirality is seen in human hands, where one is the exact mirror opposite of the other.

Properly constructed amino acids are key to life: DNA is the recipe book or book of blue prints of all the important proteins our cells need and use for life functions; RNA goes to the proper section of DNA and makes the copy of a specific protein, then takes it to the ribosome; the ribosome builds the protein using amino acids.

LUCA, or the Last Universal Common Ancestor, for some reason developed using only one of the dual orientations. Pretty wild stuff. Every specie alive today and every one of the billions of species extinct today had the DNA-RNA to ribosome-built protein using only that same one orientation.

If there were so-called "mirror" cellular life, could it be a bacteria that could harm us? Could it be a virus? The answer to that would be, if those things do exist, they pose us no threats. The way those entities attack other cells would be useless on our opposite-handed structure, like the wrong key for a door.

Some scientists are trying to create mirror protozoa and the like. Into tiny fat droplets that mimic tiny lipid-filled cellular structure, the scientists are placing mirror proteins made from a mirror ribosome. One scientists says that just by placing these things together doesn't make it work. Another says that if it does kick start, you better hope it doesn't get some chlorophyl and escape the petrie dish and make it to the ocean. In that doomsday scenario, after six hundred years we'd be in an ice age and humans wouldn't really be around to mess things up.

Would you be surprised if there turned out to be some colossally huge amount of money in the discovery/harnessing of mirror particles?

  1. Okay, so I believe this is above my brain... I will read it again and see if the petrie dish of a brain of mine can understand this. And no I'd not be surprised to discover vast sums were being spent to harness mirror particles. It would be really cool if they'd ask you to join in the search and pay you vaster sums of moola....
