It would be like trying to walk across a more slippery surface than the ice on an ice rink. Your car brakes would simply lock up and leave you sliding forward into destruction.
If suddenly no technology in this world then no one will be able to see my answer... :)
we can fly
stars
It doesn't quite make sense for that to happen. Obviously it doesn't make sense from the point of view of energy conservation. Also, mechanical energy consists of kinetic energy - so all objects would suddenly have to stop moving. Mechanical energy also consists of potential energy (including gravitational potential energy), so all objects would suddenly have to be at the lowest possible gravitational potential - presumably, all objects in the Universe would have to come together into a black hole or something like that.
The population would decrease. APEX ...
we would die
They would die
lots of things would all fall apart
they would suddenly shoot forward at extremly high speeds.
we would die, too
The earth's water would evaporate.
nothing it proobaly would die
