RE: The Antimatter Factory: Part 1 - What is antimatter?
The equation resulted in two possible solutions, one for an electron with positive energy and another for negative energy.
Why is then the anti-property attributed to charge and not to mass/energy? Could a positron be a negatively-charged negative mass particle?
And another question:
Are there going to be experiments to test a gravitational mass of antimatter on this factory?
The consensus among physicists is that antimatter has positive mass and should be affected by gravity just like ordinary matter. There are currently two experiments in the antimatter factory which are investigating the effect of gravitational force on antihydrogen, GBAR and ALPHA-g, which I will write about in future blog entries.
