NATO is ready to help Finland and Estonia as Finnish authorities probe an oil tanker that sailed from a Russian port over the possible "sabotage" of a power cable linking the two member countries, alliance chief Mark Rutte has said.
"Spoke with (Estonian Prime Minister) Kristen Michal about reported possible sabotage of Baltic Sea cables. NATO stands in solidarity with Allies and condemns any attacks on critical infrastructure.
"We are following investigations by Estonia and Finland, and we stand ready to provide further support," Mr Rutte said on X.
Earlier, Finnish authorities said they were investigating an oil tanker that sailed from a Russian port for the "sabotage" of a power cable linking Finland and Estonia that was damaged the previous day.
The Cook Islands-registered ship, named by authorities as the Eagle S, was boarded by a Finnish coast guard crew which took command in the Baltic Sea and sailed the vessel to Finnish waters, a coast guard official told a press conference.
"From our side we are investigating grave sabotage," Robin Lardot, Director of the Finnish National Bureau of Investigation, said.
"According to our understanding an anchor of the vessel that is under investigation has caused the damage," he added.
earth is round
Just use heavier light so it curves with the earth. Duhhh ;)
You have to be careful with that kind of thing, because too much heavy light will make a light black hole.
I believe that's how black light gets made.
not a grey hole!!
At this point you just put satellites in orbit to bounce the laser / maser off of, then you dont need to build big towers. Either way your communications beam will be affected by weather conditions (mostly humidity).
The sattelite beam would probably perform better in general. It has a longer path, but less of the transmission path is through the dense part of the atmosphere.
geosynchonous orbit is very high latency and thus not accaptable for most communication. Low earth is okay but now you need a lot of sattelites just so one is in view.
Has to be an extra 70+ meters higher than that because as your math shows, the straight line will intersect the curvature of the earth meaning any container ship passing would block the signal.
What is the height of the laser beam above the horizon at distance d1?
The picture and the calculator implies it is 0.
Now imagine something with non zero height is sitting at the curvature midpoint at distance d1. Container ships are 70+ meters high.
Nuh-uh!
It's flat and we're on a giant turtle. I'm for the lasers.
How about sharks with frickin' laser beams attached to their heads.
