english: We know a lot about four forces. There must be a lot more, but those are at very, very small distances, and we haven't really interacted with them very much yet.
non_english: Vieme toho dosť o štyroch silách. Musí toho byť však viac, aj keď na veľmi, veľmi malých vzdialenostiach a s nimi sme zatiaľ až toľko interakcie nemali.
