no. the light waves would still be travelling right now towards that point. The moment the mirror is put there, the waves start to be reflected.
But you do have a point, you wont be able to see until the mirror has been there for 10 years (you would see the mirror being constructed 10 years later on).
yeah, 1 lightyear = 9,454,254,955,488 km; thats over 9 trillion kilometers, so that means 10 lightyears would be 94,542,549,554,880(94.5)trillion kilometers away. And in miles, 94,542,549,554,880 kilometers would equal about 58,746,016,734,073 mi.(58.7) trillion miles. Light travels at a constant, finite speed of 186,000 mi/sec. A traveler, moving at the speed of light, would circum-navigate the equator approximately 7.5 times in one second. The speed of light is about 371 million mph. The fastest man made ship the Challenger was recorded as going about 18,000 mph. Which means it would travel 157,680,000 miles per year. that means for the challenger to travel one light year it would take 20,611 years for a man made machine to travel one light year.
Answer= 20,611 years, and that is just one light year. 206,110 years is a long time. so you definately won't see yourself.
traveling at the speed of light, it would take 4900 years to get to Alpha Centauri (the closest star to the sun) and that it only 4.37 light years away from the sun. double that, and you get about 10 light years. Traveling at the speed of light, it would take roughly 9800 years to go ten light years.
#4 mass and weight are two different things. Weight is more like the effect of gravity on an object. Mass is how much matter that object has. Say you had a rock and it weighed 25lbs on earth. now you take that same rock and moved it to I don't know Jupiter. The weight of the rock would be completely different however the mass of the rock wouldn't change.
The first one is just stupid, the little zeppelin is called an helium bottle... I hope that you know why a zeppelin fly? And if you compress a gaz, it will get liquid, thus, heavier than air and then, i won't goes up... (I know that troll science, but, i just read the first one and i didnt liked it :D )

So, its a 10 year project, not 20 year.
Had a few beers but, us British got to stick together eh?

so, it is definately, NOT possible.
What the fuck?
