Undergrad Is gravity affected by mass on the earth?
Thank you for clearing that up for me. If gravity is solely caused by a warping of space by the earth, then how can variations in gravity due to the density of relatively small local areas of the Earth be explained? Wouldn't the interaction of the Earth with space be uniform, thereby causing... -

Undergrad Is gravity affected by mass on the earth?
Yes I read it. Please explain, then, why gravimeters work as described. -

Undergrad Is gravity affected by mass on the earth?
To me, this suggests that the answer to my question is yes, since the gravity measured over denser deposits of minerals is different from measurements over less dense deposits. The reason that I want to know this, is because of the theory that gravity is a result of the curvature of space... -

Undergrad Is gravity affected by mass on the earth?
I am just trying to determine, in the purest theoretical sense, if the mass of the mountain would contribute to the pull of gravity, making the instrument on top of the mountain measure more gravity than the one in the valley. Maybe I should change the location to some unknown planet. The... -

Undergrad Is gravity affected by mass on the earth?
If all matter exerts some amount of gravitational pull, why wouldn't the gravity be higher on top of the mountain, since there is more matter under the instrument on top of the mountain? -

Undergrad Is gravity affected by mass on the earth?
Lets say that you have a valley 6 miles deep. Next to it, is a mountain 6 miles high. Assume that you have a measuring device that is capable of measuring infinitesimal differences in gravity. The entire area is made of the same material, from the top of the mountain right down to the core of... -

Graduate Why can we not see the future?
The original question was "Why can't we remember the future?" Both of us seem to agree as to why. We just differ on our views of time. I don't believe that the future is set, which means that time cannot exist as we define it, or as current physics defines it.- jeryst

Graduate Why can we not see the future?
The key word here is "current". Just because theories are current, doesn't mean they are correct. They are current because it's the best we have been able to come up with, that the majority agrees with. Every time we send up a new satellite, or launch a new probe, we are "surprised" to find that...- jeryst

Graduate Why can we not see the future?
We don't remember the past. We remember events that happened to us, and their relationship to one another in relation to our existence. You can't look into the future (just liike you can't look into the past) because time is only a concept created by us to help us explain those relationships.- jeryst

High School Hi - What is perpetual motion?
I'm not sure I understand your response. -

Is Time Merely Constant Change?
Distance is the relationship between the relative locations of multiple objects. Time is the relationship between the relative locations of multiple events. Both only exist as a means for interested parties to use, explain and/or convey those relationships. Therefore they are both nothing but...- jeryst

High School Hi - What is perpetual motion?
Isn't every atom in the universe a perfect example of perpetual motion?
