Why we don't feel the universe acceleration ?

AI Thread Summary
The universe's acceleration is a metric expansion rather than a proper motion acceleration, meaning it doesn't produce sensations like those experienced in an elevator. This form of acceleration does not affect objects in a way that can be felt; instead, it causes galaxies to move farther apart over time. The distinction between metric expansion and proper motion is crucial for understanding why we don't perceive this cosmic phenomenon. As a result, the acceleration of the universe remains imperceptible in everyday experiences. Overall, the universe's expansion operates on a scale that is fundamentally different from familiar forms of acceleration.

Why we don't feel the universe acceleration ?

Thanks in advance

The acceleration of the universe is a metric expansion, not a proper motion acceleration. Nothing "feels" the acceleration because it's not the same thing as going up in an elevator, which is actual acceleration. In the universal acceleration on cosmological scales, things just get farther apart.

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
