I'm going to assume that my last posts haven't provoked a crisis in general relativity that you're struggling to reconcile. I just wanted to say thanks for taking the time to answer what must seem like a stupid question to you. I'm sure its as frustrating trying to straighten out popular...

I'm calling Bs on most of the answers I received. I'm trusting you guys to think about the questions before you answer but look at some of the sloppy answers I got because you pooh poohed me without thinking. 1).No. Gravity does not "constrict motion Increased gravity would increase the...

Is it possible that gravity affects time by constricting motion? We know that gravity can redshift light so if time is measured by the vibration of cesium atoms might it be similar to the effect of a pendulum being slowed by adding weight. That is the dilation of time is caused by the force of...

because I'm pretty dumb. I wouldn't know where to start.

During a harmonic convergence of the major planets does the barycenter ever leave the suns sphere?

Or when you put the stakes in the ground and measure the angles are different in both axes, just knowing that they are different tells you the Earth is curved in both directions, doesn't it? Brilliant! thanks for the responses. Especially the cat one.

Because I must be a masochist I would like to know how I could convince a flat earther that the Earth is a sphere. The way I've chosen to do it is the following. I live in Honolulu and the person I am trying to convince lives in south america. At an agreed upon time we both take a 50 cm stick...

I sometimes hear on astronomy documentaries that our earliest radio transmissions could be received by aliens in our galaxy. Assuming the stations power was 1000kw at 1 mile(wild guess on my part) the power of the signal at 1 light year would 1000kw/7 trillion squared. Is this right? If so...

This is what I don't get. Brilliant scientists like Fred Hoyle and Halton Arp posit alternative theories and are labelled crackpots for their efforts. I can't understand the details (I have read a lot of introductory astronomy texts but without the the advanced math they read like a dungeon and...

Another question for you all. What evidence for an expanding universe is there besides redshift. I am a layman and to me it seems like it would be simpler to find another explanation for the spectral shift of light as it passes through millions of light years of space (say some kind of lensing...

Thank You all for your considerate responses. I didn't know what to expect in terms of the answers I'd receive but I appreciate your courtesy. Whatever I may think about theoretical physics I know the physicists are gentlemen! Sincerely

I like to think that I have a moderately complete education in science and liberal arts, recently though the popular physics shows I used to love leave me completely bewildered.For example Lawrence Krauss says that two + two equals five for sufficiently large values of two. Epistimologically...
