I’m calculating the numbers of years that the
point 67 % part of the speed of light , or, 0.000,006,7 % of the speed of light,
from the 0.000,056,7 % of the speed of light ratio calculated above
would take off from the 86,000 years approximation.
It could be greater than 10% less time since
the speed is 2/3 faster than if it would be only half of that 43,000 years .
Additionally, l am reviewing 2 percentages in the original post, as one of the 2 seems to be a number which is not a percentage.
The magnitude of difference is exactly of 100 or, 3 decimal digits, which may very well be the case.
It may be over 1,000 or 10,000 times more simple to communicate with that system (Alpha Centauri) than to go there.
This includes sending data in electronic format or other similar format.
It would have to be reliable enough and new systems can be develop to deal with the time frame involved to receive and send communications.
In other words, we would have to communicate in programs, or, message packets, because there would be years in which we could not interact directly.
We could send programs in 4.3 years, and get feedback from them 4.3 years after they completed their procedures and proceedings.
To send updates from the data received would take another 4.3 years which is equal to triple that amount. 4.3 x 3 = 12.9 years.
This, is including data back from there before being sent back…
If the data from there is included in a system which is arriving there, and sent before the arrival back from the reply, if the data is met at halfway, it would take the time to send the first one, 4.3, plus half the way back, 2.15 + the other 2.15 back on it’s way there, while the first reply is coming back to us in our system = 8.6 years.
Two generations should not be enough except for part of the first one way trip.
This does not include generations on board the system to travel there.
This includes only the time-frame involved for unmanned system with no life on board to go there.
Also, it may be possible to “leave things” to be seen later along the way.
This may not be the best option, as it could slow down the process.
However, if it can improve the chance to get resources there, or to be able to use resources required to get there, it may be an option.
If we can see there, it may be possible to see us from there as well, and so therefore, we are already there.
There could be other ways to get there.
The calculation error could be in the figure:
“The Voyager I spacecraft traveled at 17 km per second (or 17,000 m /s).
Compared to the speed of light , at 299 792 458 m / s , or 299,792.458 km per second,
it is = 5.670598281475156e-5 or 0.000 056 7 % of the speed of light.”
when compared to :
“So, this is less than 0.1% of the speed of light (at which rate it would take 4,300 years) or at 0.01% of it for 43,000 years.
Half of that speed is 0.005% of the speed of light and would take 86,000 years for the trip to get there.”
Unfortunately, I don’t have the time for that now, and I will verify this later.
It is merely arithmetic and does not include the expansion of space itself in which the speed of light is directly affected (which does involve mathematical calculations rather than arithmetic only , in scope).
Yes, that was it, the first number is not a percentage but a ratio.
So, the second percentage number is correct.
1 / x of 0.5 =
1 / x of 0.567
1.763 668 4
= 75,837 years.
Communication Warfare attack against the communication could also delay the system or cause other results, potentially negative.
