NOVA | Einstein's Big Idea | Relativity (Lightman Essay) | PBS
This website contains a lot of good information, but it is not overwhelming, which makes it easy to read. Also, it has illustrations that help you to understand the theory of relativity. It is credible because it was written by a physicist and includes a photograph of him and personal information to confirm that he is an actual person.
This article is about realativity and the cosmos. It gives a background on the essense of gravity and the goes on to tell more about stars. I chose this site because I know that PBS is a trustworthy orgnaization.
this site seems to be very reliable. i chose it because it was one of the first links to come up as one of the most used by other students. it seems to be written by an expert as well.hersheyhslibrary » Theory of Relativity

This will help me with my physics project.
On this web site you'll see how it talks about relativity. No on was general relativity the first major new theory of gravity but it was the first one since Isaac Newton's more than 250 years earlier. Many of the predictions of general relativity have been quantitatively confirmed by experiment. It also talks about how Einstein and others applied general relativity to the structure and evolution of the universe as a whole.YouTube - Einstein's General Theory of Relativity | Lecture 1

"Does gravity really alter time and can this weird phenomenon be detected with a family road trip experiment?" -- via Jed Parsons

n September 2005 (for the 50th anniversary of the atomic clock and 100th anniversary of the theory of relativity) we took several cesium clocks on a road trip to Mt Rainier; a family science experiment unlike anything you've seen before. By keeping the clocks at altitude for a weekend we were able to detect and measure the effects of relativistic time dilation compared to atomic clocks we left at home. The amazing thing is that the experiment worked! The predicted and measured effect was just over 20 nanoseconds.
Experimentally proving relativity by taking atomic clocks up higher in elevation (to increase speed due to Earth's spin being different). A family vacation with three kids.e=mc2: 103 years later, Einstein's proven right - Yahoo! News
For those keen to know more: the computations involve "envisioning space and time as part of a four-dimensional crystal lattice, with discrete points spaced along columns and rows."
"Until now, this has been a hypothesis," France's National Centre for Scientific Research (CNRS) said proudly in a press release.
According to the conventional model of particle physics, protons and neutrons comprise smaller particles known as quarks, which in turn are bound by gluons. The odd thing is this: the mass of gluons is zero and the mass of quarks is only five percent. Where, therefore, is the missing 95 percent? The answer, according to the study published in the US journal Science on Thursday, comes from the energy from the movements and interactions of quarks and gluons.
