If time is relative to each observer traveling at different volocities and subject to different gavitational fields, and both observers measure the speed of light exactly the same using clocks that are running at entirely different speeds, isn't light in fact traveling at different speeds and constant only because it covers the same distance in relation to each observer's clock?

My husband recently began thinking about getting circumcised. Oddly enough i've never been with a circumcised man and didn't really know how to respond when he told me he was thinking about having it done? How will lovemaking feel different? Has anyone been in a similar situation? Well any answers/advice would help really.

so many people think that NASA waste our tax dollars. Does anyone know what great inventions or things have been developed that make our lives easlier because of our Space Shuttle Program began.

According to theory, if we were to travel at the speed of light, we would circumvent the entire universe in zero time. Why then does it take light so damned long to reach us from the outer stars?

Is it possible that the massive amounts of antimatter are so far away we have no way of knowing they're there or is there some kind of proof for the dominence of matter? I know they haven't found any "power flux" of gamma rays where the atoms and their anti-components are colliding with the probes they send up but how far are they accurate to? Has the whole theory just basically slipped to a treasure chest for sci-fi writers?

I am a student entering my senior year at a major university. This past summer, I have rediscovered a passion for biology, primarily through reading Richard Dawkins. It occurs to me that I don't see much of a future in literary analysis and I find the subject of zoology fascinating. I am currently signed up to take Bio 101 for next semester, but I relatively little time to work with. Should I try and scrape together a bio minor by taking some summer courses or perhaps another semester? Or should I just try and graduate with as high a GPA as possible, take a bio course or two to get a feel, and apply to grad school that way? Or any other possibilities? I am very unsure what to do and would appreciate any help from those with relevant or similar experiences.

The magnetic orientation and geologic dating of ocean floor rocks is a key piece of evidence for plate tectonics. Yet I've always wondered, how do scientists get samples from the bottom of the Atlantic?

A) No, because this would have no physical meaning
B) No, because the kinetic energy of a system must equal it's potential energy.
C) Yes, as long as the total energy is positve.
D) Yes, since the choice of the zero of potential energy is arbitrary.

I don't have an incredibly firm grasp on relativity, but its my understanding that all matter contains its own gravitational force and that a body's total grav force is proportional to its mass. We stick to the earth because all of its mass is below us. If one could stand in the center of the earth (without burning up, suffocating, etc.), what gravitational pull would they feel? Since they have equal mass surrounding them on all directions, would they be pulled apart? Or would they be crushed because gravity still pushes inward through some mechanism?

With my thumb extended at arms length,I can measure the moon at the horizon,and again straight over head to be about 3/4's of my
thumbnail,or about 1/2 degree.Yet the moon at the horizon appears several times larger than it does against the night sky.
Why???
