RE: Travel Time to Alpha Centauri - Python Program
With acceleration/deceleration of 1G is there a top speed reached? Speed of light? And incredible that the relative time passed on Earth is 166% more time passed.
I calculate 0.95 times the speed of light. What is actually even more interesting is that it doesn't take much more time to cover a lot more distance. To reach a thousand light years would take 13 years ship time, but back on earth just over a 1000 years will have passed, and by the time you got a signal back to earth yet another 1000 years will have passed.
That is really amazing, how time is so relative to your situation.
It is basically relative to speed and gravity! The higher the speed at which an object moves or the more powerful the gravitational field an object suffers from, the slower time flows as observed by this specific object.
Great answer, thank you!
Funnily enough, I cannot resist from advertising one of my old articles where I showed that it was possible to reach the end of the observable universe and come back in less than a human lifetime even with a constant acceleration of 1g. See here. I hope you will enjoy it :D
I just recently did a piece similar to yours, well, if you minus the fact that mine was not as articulate, not only speaking of the mathematical equations, but showing the work too! Haha, it was a great read for sure. Much more in depth than I took it and very well explained so someone who enjoys physics or fishing could retain and understand what you explained. @terrylovejoy has been a great Mentor so far for me. Steemstem seems to have a very meticulous and fine tuned team I will say that. Ive only known terry for a short time and he has helped me improve in great strides so I too can produce the quality this group is expected to publish. Cheers.
I just read your post. Indeed, including a bit more structure on it could have been useful (it is kind of pretty hard to read, to be honest). However, you have really improved with your last one on the gravitational wave :)
Thank you so much for the compliment @lemouth. I've never been one to writr, clearly, until now and @terrylovejoy has been a tremendous help. If I do something I really try to do it my best. Some things just take practice. 👍🏻
However, please don't ask me to work for you! This is not how it works around here...
😂 noted sir.
Thank you for the complement's @param3dic , that means a lot!
That's brilliant, you've also included the analytical method for calculating this in the post (rather than the brute force method above). The sad thing is that there would be probably nothing to come back to from that journey :(
Totally, although as I said it in my post, it is not clear we will be able to ever accomplish it as we are missing the technology so far.
Yeah, nothing we can fathom can actually travel faster than speed of light. The calculations based on a trip traveling at 1 G accelerating first half of the flight and decelerating the second half is what they are seeming to see as the sweet spot. When you get into time dilation due to special relativity it is just mind boggling. With the exception of a few close places, any were else is a one way ticket bc the amount of time passed here means Earth could be destroyed of at the very least humanity. And the crazy thing is most people do not thing about there is a difference between interstellar and intergalactic travel. If we actually were to travel intergalactic at 1G to the closest galaxy to us, Andromeda, it would take 60 years about the craft and 5,000,000 years will have passed on Earth. So you either set off as nomads really vs explorers. Until there is something unbelievably radical discovered, such as how to not only make a worm hole, but control the start and finish to where you want to go. Then you are talking more like stepping through a doorway bc you have literally folded space-time in half. It’s truely mezmoring when thinking about things like this. The flip side is its almost disheartening and really makes it feel as though we are not meant to go beyond our playground. Sorry for the massive ramble session! :)
On the contrary, we like people who constantly ask questions. It's the path to our future :P
Thanks for sharing!
I certainly agree! Thanks for the read
