If I was in a spaceship continually accelerating at 9.81m/s squared (1g) in a straight line, I would reach near light speed within a year.

On earth, we are in a gravitational field of 1g, which according to the equivalence principle means we are effectively accelerating at 9.81m/s squared.

What does this mean? How can we be accelerating without increasing our velocity? Is there some way of looking at this, from some other inertial frame, that means we are travelling near light speed?

If I was in a spaceship continually accelerating at $9.81m/s^2 =1g$ in a straight line, I would reach near light speed within a year.

On Earth, we are in a gravitational field of $1g$, which according to the equivalence principle means we are effectively accelerating at $9.81m/s^2$.

A thought experiment

If I was in a spaceship continually accelerating at 9.81m/s (1g) I would reach near light speed within a year.

On earth, we are continually accelerating at 9.81m/s. Are we all effectively travelling near light speed?
