What about all the literature from thousands of years, dmt experiences, near death experiences and so on. Speculation is definite but somewhere out there is the definitive truth about what happens. How can you attain that knowledge. Is it even a good idea to know?

Ultimate knowledge? I don't think you can, physically. We are limited creatures, at least in our current form. I think about it this way. We have language and form concepts with it, like when you say you love someone, you don't give an exact representation, you are not 100% precise. Not only because of difference in perception of love between you and the person, but because you yourself (supposedly an imperfect being) can't do this physically. Going further, when you calculate a temperature for a example, you see it says 30C, it isn't usually precisely 30C, it can be 29.9999999999999999999C, or 30.000000000000000000001C. Applies to time, to weight, to distances. But we don't think about it, usually.

It feels that way intuitively, if it is true or not is a big question. There might be no truth in this world. 
>How can you attain that knowledge
I think it is the same as with what I wrote in begging. You can get pretty close to truth and at the point where you think you are satisfied enough with how close you are, you accept it as knowledge. Does experiment needs to be repeated 1000 times for your? For some two times is enough, some are never satisfied. 
>Is it even a good idea to know?
Ultimately, I think yes. We should always push as far as we can and then go even further in pursuit of truth and knowledge. I believe to Socrates, who compares ignorance to evil. Person may know all the math and be extremely precise in some niche calculation. Men can be very smart, but unable to accept simple truth because they think they are not 100% precise. For example, we all want mutual love, but some are ignorant about it's value and trade it for security, money, power, ego boost or something else. It is imo a false evaluation.
