Light into matter

[Pesty]

Imperial College London physicists have discovered how to create matter from light - a feat thought impossible when the idea was first theorised 80 years ago.

Have they actually done it?

Doesn't look like it - 'just' come up with an experimental design to test the theory.

This seems interesting at first but light turning into matter is hardly anything new. This should be hailed as two photon pair production rather than normal pair production which has been observed in labs for decades. Photons can turn into matter anytime if they have enough energy and momentum is conserved.

I guess that to change photons (light) into protons (matter) you just need to change H into into P....

How difficult would it be to change hydrogen in to phosphorus, then?

It's pretty easy, you just need to feed the Hydrogen into a star, and wait around for a bit.
Best to have an eggtimer ready, as you don't want to over cook it into Sulphur

What kind of star? Are we talking One Direction or Cliff Richard?

Just a minor star will do, like this guy



Hydrogen eventually becomes Argon and Selenium.

I have absolutely no idea who that is! H3.jpg? H? Steps?

Well, I did say it was a minor star...
