For once NASA is doing something right. I say in less then 100 years humans will be leaving the solar system.

If you said getting back to the Moon or possibly a Mars mission, I think you would be closer to the mark. Interstellar travel will not be coming for a while yet, if ever.

Eventually, we will do interstellar travel because our sun will blow up in a few billion years and it will be a choice of traveling or dying. I think we will chose traveling. So it will come eventually. Probably not in 100 years though.

I cannot argue completely against a conservative estimate of man's stellar travel limits - from what science has observed so far, we appear to have some serious limitations to deal with. However, another part of my brain (as was posted earlier in this thread by someone else) considers how incredibly quickly humanity has advanced in the last 200 years - and I cannot help but be convinced that such growth spurts will continue (with obvious peaks abd valleys). Thoughts on this?
