In the rocketship in deep space, the feeling of weight is present with the rocket motors on. The at rest reference frame becomes evident when the rocket motors are turned off. Please note that the at rest reference frame may be moving in relation to us. I tend to think of normal spacetime as an at rest reference frame. When we push against this reference frame with the rocket motors on, the sensation of weight becomes apparent. |
Einstein .... We may be at cross purposes. "the feeling of weight is present with the rocket motors on" .... This is what I term acceleration
"The at rest reference frame becomes evident when the rocket motors are turned off."
This is what I term velocity.
At the moment that bloody Rascal is giving me so much homework that I haven't found the time to fully study your posts. This thread is going way to fast.
If the acceleration you refer to is gravity then this is an acceleration not only thru space but thru time. Spacetime.
We don't feel the acceleration of earth because we have adapted to feel our 'weight' as normal ?? but nevertheless 90 kilos is my 'feeling' of acceleration.
I am really interested, but trying to comprehend Rascal's posts is giving me a headache.
Rascal slow down !!
cool bananas ... greg
ps: I am thinking for a while.
