Good morning, afternoon or evening to whomever may be reading. My name is Garrick Betts. I have a question that I feel may pertain to this area of physics. I must apologize now because this whole spiel will be a grammatical nightmare. Anyway... I have come to the recent acceptance/ agony of acceptance of my mortality. I feel when I pass I will experience no afterlife because my brain will die. There will be no further intake or ability to take in new information. With this recent thought pattern many random thoughts have been arising. The thoughts that I have had tonight have brought me here they are as follows: the human body is weak; martial arts, in a combat sense, would be easy with patience and anything else that lives is equally as weak. (I'm thinking oh well a tree seems pretty sturdy but no it is not it will die as well.) After these thoughts I was trying to think of what would be an apt image to focus on to develop strength, not super human, just something to aid the building of muscle, this coming from my time as a wiccan. So, I thought of a house, cool, non-living, but... made from previously alive things. The house will, in time erode. So, the question that I am posing to the scientific masses is this: what is the longest lasting, non-living, thing in the universe? Again, I do apologize for how jumbled this message is and my thoughts still aren't fully formed this was a spur of the moment had-to-know kind of thing. If you can make sense of this and can in any way empathize with me you are truly intelligent. Thank-you and have a good morning, afternoon or evening.
