Not likely, the project has no feasibility at the current time. Anyone who needs more than a millisecond to calculate this is merely trying to get publicity or grant funds so they can continue the deep fakerySmarter ones than you are doing the feasibility study.Not mathematically feasible because ofAs I understand it, Lubin's proposal has a whole caravan of probes. The trailing probes are simply repeaters that would receive the signal from an earlier probe and pass it down to the next. That totally defeats the inverse square law of the huge distance. I would guess that the probes "solar" sails would be parabolic to serve a double purpose and also act as efficient antennas. The battery power of the caravan of probes would not be needed until the leading probe was in the vicinity of the target star.A typical cellphone has enough power to reach a cell tower up to 45 miles away. Depending on the technology of the cellphone network, the maximum distance may be as low as 22 miles because the signal otherwise takes too long for the highly accurate timing of the cellphone protocol to work reliably. Now you know how things work.
Pioneer 10 is 12,000,000,000 km from Earth and still keeps in touch via small, land-base antennas.
.
1, the short telemetry range of a gram sized probe
2. the sheer number of probes needed would be in the billions
3. the inevitable fact that with billions or millions as the case may be of probes that one would fail or be knocked out disabling the chain with no hope of repair.
It's fiction kid, if you understood engineering you would know that the simplest solution with the fewest parts is always preferable to a complicated one such as this billion link chain that is failed before beginning
