Technologically it is not as impossible as some will have you believe. Humans will enjoy the ability to travel to other starsystem surrounded by a not too distant future (centuries). But such journey will be vastly different from any journey any human enjoy undertaken back. It will be a one way trip. And when you procure to the destination everyone you ever knew will be long departed. It puts the human psyche under strain it have never encountered beforehand.
not in this millennium...basically imagine that we are flying for a century...which be an ancient dream unsuccessful for millenniums
If we learn around the science of teleportation, or cryogenic suspension, maybe.
It's possible with a specialized self contained long duration space craft. The craft would own to autonomous and humans might make the trek as frozen embryos that would be reared by robots after mortal born in space once the ship get near to it's destination.
Proxima Centauri is a mere 4.2421 light years away.
(4.2421)(365.26)(24)(3600)(299,792,458 m/s) ≈
4.01344635e+16 m
Using a comfortable 1g acceleration, and mid-course flopover for 1g deceleration,
t ≈ 2√[(4.01344635e+16 m)/(9.80665 m/s^2)]
t ≈ (6.39732469e+7 s) ≈ 17,770.3463 hr ≈
740.431098 days ≈ 2.02713436 years
The maximum velocity attained would be
(9.80665 m/s^2)(6.39732469e+7 s) ≈ 313,681,621 m/s, or 1.04632926 c
For those who are unrelenting that the speed of light cannot be exceeded we enjoy to recalculate:
2as/2 = v^2
a ≈ (299,792,458 m/s)^2/(4.01344635e+16 m)
a ≈ 2.239360 m/s^2
t ≈ 2√[(4.01344635e+16 m)/(2.239360 m/s^2)]
t ≈ 2.67748320e+8 s ≈ 74,374.5334 h ≈
3,098.93889 d ≈ 8.48420000 years
This approach requires enormous rockets for small payloads, but it can be done next to today's technology. There are other problems to be solved, of course, including impact lay waste to and even "air resistance". At hard by lightspeed, solar winds must be taken into explanation. It is conceivable that interstellar gases could consideration maximum speed.
I certainly hope so or we are finished as a species. And you know, we may own our faults but humans are pretty inventive creatures, especially when their survival is at risk.
Think how far we enjoy came surrounded by the last 200 years, we hold created things people contained by the 17 century and 18 century couldn't even fathom, i do believe if we survive long enough we will own no problem traveling to near solar systems.
We ATM, project Longshot could truth-seeking reach alpha centuari
contained by 100 years, at only around 20 percent of feathery speed.
I do not think so. We enjoy to escape the Sun's velocity which is currently impossible so our chances r moderately slim but it is up to your beliefs
As depressing as it is and as much as I would preference otherwise, I think I enjoy to side with Bruce. Interstellar travel is an epic technological undertaking and I lately don't think humanity will ever be capable of muster up the resources or the will for it.
I honestly don't feel the human race will live long ample to see this day. We are too intent on sucking down the resources on Earth, and destroying the environment. 'Evolutionary dead-end' is the proper possession, I believe.
