Are electrons older than the universe?

The best measurement yet of the lifetime of the electron suggests that a particle present today will probably still be around in 66,000 yottayears (6.6 × 1028 yr), which is about five-quintillion times the current age of the universe. As a result, the electron is considered a fundamental particle that will never decay.

How many protons neutrons and electrons are in the universe?

Therefore the observable universe is defined as only the parts of the universe that are within 13.7 billion light years of us. The commonly accepted answer for the number of particles in the observable universe is 1080. This number would include the total of the number of protons, neutrons, neutrinos and electrons.

Are there the same amount of protons as electrons in the universe?

In the current universe, all evidence suggests that the number of electrons in the universe is almost identical to the number of protons, making the universe electrically neutral.

Are atoms as old as the universe?

It takes us from a hot, plasma-filled Universe to an almost-equally-hot Universe filled with 100\% neutral atoms. Although we say that the Universe formed these atoms 380,000 years after the Big Bang, this was actually a slow, gradual process that took about 100,000 years on either side of that figure to complete.

Are all electrons the same electron?

Every electron in the universe has exactly the same mass, exactly the same charge, and if you think about it, there’s no reason why they’d have to be. According to him, the reason that every electron is the same is because every electron is the same electron.

Why are there equal numbers of protons and electrons?

Actually the proton and electron count of an atom are equal only when the atom is neutral in charge. The electrons are found in orbitals surrounding the nucleus. In order for the atom to remain electrically neutral the protons and electrons must balance each other.

How is the age of the universe determined?

Astronomers estimate the age of the universe in two ways: 1) by looking for the oldest stars; and 2) by measuring the rate of expansion of the universe and extrapolating back to the Big Bang; just as crime detectives can trace the origin of a bullet from the holes in a wall.
