I understand what you are saying. However, say we were in the time reference of your second race, but were watching the first race. Yes, at the instant they happened both took 10 seconds to run 100 meters, but we are actually looking at the past the further we look since the speed of light is...

I found the source: http://www.dailygalaxy.com/my_weblog/2008/01/scientist-says.html . Admittedly, to my knowledge, this doesn't account for the affect of dark energy on a more "local" scale, such as the rotation of galaxies. Take a look and let me know what you think.

I hate to post two threads in a row, but I have too many physics questions going in my head to sleep. My TA last semester told us he was taking a QM course and told us his uncurved class average was a 37. This leads me to think that no undergrad can grasp QM. Now I know only the most basic of...

This may be the wrong place to put this thread, but it appeared to be the best option. Does anyone know of an easier way to set up physics equations online other then finding the keystroke or inserting a symbol? It's a pain to hold ALT on my mac and hit every key trying to find an integral...

I read an article about 2 weeks ago (another astronomy major sent it to me, but unfortunately I'm having trouble find it, when I talk to him again I'll get the source and post it) that proposed an alternative to the universe expanding. The article stated that the reason we see light redshifted...

I'm starting my second year as an astronomy/physics double major. Up to this point, I've only had basic foundation courses, most of which I've come across in high school. I know this question is highly subjective, but when do the courses start to become really difficult? I've heard from TAs that...

I currently work for NASA at the Goddard Space Flight Center in Maryland, US. I am currently an undergrad physics and astronomy double major at the University of Maryland. I do solar plasma physics research on the STEREO spacecraft . One of the scientists I work for is a professor at Maryland...

Hey everyone, I'm entering my second undergraduate year as an astronomy and physics double major. I've always had an interest in black holes, high energy astrophysics, and cosmology; consequentially, I've planned to study one of these in graduate school. However, over the summer I've been...
