One atom in space what happens

In summary, the conversation discussed the possibility of a single atom existing in space without any external energy or heat. It was determined that if the atom is in its ground state, it will remain in that state indefinitely, but if not, it will emit photons until it reaches its ground state.

This question is something that's been bothering me for a long time, there has to be a probability in this universe where a single atom is/was floating in space alone without any light exciting it. Clearly there is no heat here, so does the atom approach absolute zero asymptotically? My question is what would happen to an atom and its quantum states if there was no heat or energy being supplied to it. Would eventually the quantum states breakdown or is an atom stable without bouncing off other atoms or receiving light?

If it is in its ground state, it would just stay in that state forever. If not, it would emit photons until it was in its ground state, and then stay in that state forever.

i thought that was the case, thank you for clearing that up.
 

FAQ: One atom in space what happens

What is an atom and how does it exist in space?

An atom is the basic unit of matter, consisting of a dense nucleus surrounded by a cloud of negatively charged electrons. It exists in space as a result of the expansion of the universe and can be found in various forms, such as in stars, planets, and interstellar gas.

What happens to an atom when it is in space?

An atom in space experiences various forces, such as gravity and radiation, which can affect its behavior and properties. It may also interact with other atoms or molecules in its surroundings, leading to chemical reactions and changes in its composition.

Can an atom survive in the vacuum of space?

Yes, an atom can survive in the vacuum of space as long as it is not exposed to extreme conditions, such as intense radiation or extreme temperatures. In fact, many atoms have been found to exist in the vast emptiness of space.

How does an atom behave in the absence of gravity in space?

In the absence of gravity, an atom will still have its internal forces, such as the attraction between the positively charged nucleus and the negatively charged electrons. However, its movements and interactions with other atoms may be affected by the absence of a dominant force like gravity.

Can an atom in space ever be completely isolated?

No, it is highly unlikely for an atom in space to be completely isolated. Even in the vast emptiness of space, there are still particles and radiation that can interact with an atom. Additionally, the expansion of the universe means that atoms are constantly moving and interacting with each other.
