Space exploration: Where do we go from here?

Therefore it would take roughly 60 years to achieve 1 light year. The nearest 'suspected' terrestrial exoplanet is roughly 4 light years from the sun?

A lot of it is mission choice. Those are few data points and different priorities would have given us different results.
Our fastest probe right now can do 300k mph. Our fastest in 1971, fifty years ago, could do 30k. So let's say that's our Moore's Law: max speed increases 10x every 50 years.
1971 30k
2021 300k
2071 3M
2121 30M
2171 300M = .44 ly/h (Earth to Proxima Centauri in 10 hours ship time -- relativistic effects mean more time has passed on Earth)
If the same law holds for developing FTL, then:
2221 4.4 ly/h (Earth to Proxima Centauri in 1 hour ship time)
2271 44
2321 440
2371 4k
2421 40k
2471 400k (from one end of the Milky Way to the other in 1 hour ship time)
2521 4M (from Earth to the Andromeda galaxy and back in about 90 minutes ship time)
2571 40M
2621 400M
2671 4B
2771 40B (complete circuit of the known universe in 2 hours ship time)
So we can see the universe in a day if we just last the same amount of time that has elapsed since the birth of Roger Bacon, pioneer of the scientific method.
A high level summary of human history, by century:
G00 Gilgamesh (2000 BCE)
G10 The Iliad
G16 Aristotle
G26 Brahmagupta
G33 Roger Bacon
G40 Ned Harkness
G46 Entire universe explored

It took 50 years to get to 1 light-day. It's going to take a hell of a lot longer than 60 more
Sometime around the year 19,620

Isn't warp a logarithmic scale?
Edit: LOL! This is great. And not at ALL what I picture in my head.

Um ... ah ... folks have the gauges figured out, now we just need the vehicle and engine ... I guess ...

Ok, I couldn't wait.
Is there any kind of theoretical limit to Solar boundary, gravity-assisted speed? There has to be, right?
God bless Stack Exchange, Yahoo Answers for smart(er) people.
So at some point, Kepler's scale breaks down and something else has to drive. Because so far, we've been using gravity assists for all spaceflight so far. Gravity assist can only get you so fast without requiring more "interactions" with the sun and jupiter and it just isn't going to work.
If you take:
(Chemical Propulsion)+(Gravitational Assist)+([SUP]-[/SUP]\_(")_/[SUP]-[/SUP]) = speed
When does GA become small relative to CP and ([SUP]-[/SUP]\_(")_/[SUP]-[/SUP])?
I don't know. But I do know Lynah is going to spend an hour typing up an amazing reply that both answers the question, questions chemical engineers' intelligence, and make us all laugh at the same time. :-D ;-)

Eh, 2081 might as well be 19,620 for you and (likely) me.

I dunno about you man but with my family's genes 118 isn't a stretch.

Assuming man could today propel a similar object at 10x the speed of Voyager 2, it would take 6 years to travel one light day, 2,190 years to travel one light year and 4 to 12 times that to reach the nearest estimated extraterrestrial exoplanet.

So in spite of many years of development, and watching how SpaceX SHOWS a launch- Blue Origin still sucks at the presentation.
Sounds sucks really badly, and the video seems as if it was from the 60's, but in color- and we could barely understand what they were saying. Whereas SpaceX has high def cameras all over the place- there would have been 5-6 live feeds inside the cabin that would not have broken up at all.
Not a fan of either billionaire, but come on Bezos. Copying a better product is not a bad idea, this is more like one of your crappy copy's that you charge a fortune for.

Are these private space companies allowed to use/develop nuclear power sources?

Hug someone you care about...
Yep. How about instead creating a way to wank off at 50 miles up you, oh I dont know, END FUCKING HUNGER YOU SELF IMPORTANT JACKWAGONS! Fund Climate change research and green tech implementation. (shut up Elon you are no better) Fix homelessness or fund education...
NASA Astronauts are heroes (especially the early ones) these guys are fucking COSPLAYERS with too much money and too little dicks.

They could probably afford to do both things. I doubt it occurred to them.

Yes, yes, and yes. At least Gates has done something worthwhile with his fortune.
