My take:
- there is no universal time, there is your time and an external observer's time
- if you fly straight at a planet, you crash into it in a finite your-time, for an observer behind you, the light of your crash will be delayed by a tiny amount due to the planet's gravity
- if you fly straight at a highly massive neutron star, you crash into it in a finite your-time, just a bit quicker for youself due to its great mass, and the light of your crash will be delayed a bit harder, but will escape and show that you crashed
- if you fly straight at a black hole, you crash into it in a finite your-time, just much quicker due to the high mass of the hole, and the light of your crash will be delayed indefinitely, and will not show that you disappeared
Interesting idea. :) What kind of a mattress do they use for leveling roads?
The current plow has many problems:
Generally, a snow plow does level the road also - but only a little because the ground is frozen and everything is slippery, and the mechanism (with a spring if fancy) is holding it just above ground. When I look at my plow after working, the steel of the downward edge shines - it has worked hard against the ground.
