If we copied/moved our planet and us as we are now back in time that far away, what would happen?

Could we survive, or are we bombarded to death by something, or something else?

    Space wasn’t 0 Kelvin (I’m assuming you mean “absolute zero” because outer space is currently colder than 0°C/32°F) at any point in the past. In fact, the farther you go back in time, the warmer the universe gets, on average. This is because the same amount of energy was packed closer together when the universe was smaller. As the universe got bigger and things moved farther apart, the average temperature got colder.

    As for what would happen if we magically teleported ourselves back to when the universe was very young, we would be cooked from all the radiation that was flying around, or if we went really far back, we’d just be blown apart because the entire universe was a hot plasma.

      I think you also misread my question/thread title 😁

      I know this. Space was Planck temperature in the first very short time when it was born. After that it started cooling down.
      I tried to go back in history with my question.

      Okay, so at the general space temperature of 0 celsius the radiation was still too crazy for us to survive?
