Whr did the elecrons come from?

In summary, the conversation discusses the formation of nucleons and electrons during big-bang nucleosynthesis and baryogenesis. It is mentioned that photons appear at the very beginning of the Big Bang Theory. The term "leptogenesis" is also mentioned as the process for the formation of electrons.

when we talk abt BBN, we only talk abt the nucleons. whr did th electrons come from? was it just beta decay or something else?

Actually nucleons did not form during big-bang nucleosynthesis. The big-bang nucleosynthesis fuses them into light elements, fixing relative abundances of the elements. The nucleons formed previously in a period or process called baryogenesis. For electrons, the corresponding process is called leptogenesis.

At what time frame do photon's appear in the current Big Bang Theory?

'Leptogenesis'. That's such a beautiful word! Now to casually drop that into a conversation when buying milk.
 

1. Where did the electrons come from in the first place?

Electrons were created during the Big Bang, the event that is believed to have started the universe around 13.8 billion years ago. During this event, energy was converted into matter, including electrons.

2. How are electrons produced?

Electrons can be produced through various processes, such as radioactive decay, nuclear reactions, and the interaction of particles in high-energy environments. They can also be created in laboratories through the use of particle accelerators.

3. Can electrons be destroyed?

Electrons cannot be destroyed, as they are considered to be fundamental particles, meaning they cannot be broken down into smaller components. However, they can be converted into other forms of energy through processes like annihilation with a positron (the antiparticle of the electron).

4. Are all electrons identical?

Yes, all electrons are identical. They have the same mass, charge, and other physical properties. This is because they are considered to be elementary particles, meaning they do not have any internal structure or variation.

5. How do electrons contribute to electricity?

Electrons are the carriers of electric charge, which is the fundamental property that allows for the flow of electricity. When electrons move through a conductor, such as a wire, they create an electric current, which can be harnessed and used to power devices.
