To make antimatter you have to change the charge of proton and electron. So how do you do it
Hello bhobba. This has confused me. Should we take your first sentence literally? As I understand (understood) it, an electron has a charge which I thought was considered to be a fundamental constant. But in your first sentence you seem to be suggesting its charge is not a constant but somehow increases as something gets closer to it. Does that really happen?Just as an added twist the closer you get to an electron the bigger the charge - it depends on the energy scale. It was this that confused the early pioneers and led to infinities and the invention of renormalisation to tame it. The full understanding came with the work of Wilson he got a Nobel for:
There is a constant, and both classically and (with some corners being cut) in non-relativistic quantum mechanics an electron is an idealized point particle with charge equal to that constant; it's the field strength that becomes infinite as you move arbitrarily close to the electron. It gets much messier in quantum electrodynamics, and that's what Bhobba is talking about.As I understand (understood) it, an electron has a charge which I thought was considered to be a fundamental constant.
Yes - not really appropriate at the B level - I just mentioned it as an aside, bot probably shouldn't haveI'm not sure that a B-level thread is the right place to carry on this discussion; we've already come close to hijacking the original thread.
This is the relevant bit in the above article in case you missed it:I have looked at the wiki article and have also searched elsewhere but am still none the wiser. Would you be able to clarify the matter please? Thank you.
