I really hope there is some way scientifically to ascension like in the stargate series. Ascension would need extremely advance scientific knowledge though. Yeah I know it is sci-fi but it does not seem impossible to exist as a energy being. We are made of atoms, atomic particles, and energy at the basic level. Existing as a energy being would possibly end death completely, unless you get sucked into some blackhole, but you should be able to detect blackholes as being directly made of energy.
My goals in the following order:
1. Have extreme life extension, and continue to add genetic enhancements to increase survival
2. Become biologically immortal
3. When the technology arrives, possibly become bionic or have a nanobot or robotic body.
4. If scientifically possible one day ascension
I think 3 would probably take at a minimum one century to occur. Scientific knowledge probably will greatly increase from there and 4 would probably take at a minimum one thousand years to occur if enough people work on it. If there becomes a way to speed up or skip a number closer to 4 then that is even better too.
