  1. Disagreement with other measurements. Error here?
  2. Incorrect assertion: "The only thing that can travel at the speed of light is light, and if gravity can travel at the speed of light, then it's almost definitely the same thing as light. Also, there's no gravity or light in outer space. Almost certainly a sign that gravity and light are the same particle. " "it's almost definitely the same thing as light." Where did you get this? "there's no gravity or light in outer space" False
  3. It is too soon to say. There are about 100 billion stars in the milky way. Only an infinitesimal number has been explored to determine whether life supporting planets exist.
  4. The Big Bang was less than 14 billion years ago. The speed up of the expansion was discovered during the 1990's by using supernova 1A /science.nasa.gov/astrophysics/focus-areas/what-is-dark-energy https://www.e-education.psu.edu/astro801/content/l10_p9.html
  5. Gravity and e-m forces can be made 0 in isolation. Place object halfway in between attractions of equal strength. Also neutral things don't experience e-m.
  6. In the latest issue of American Scientist there is an article by Tony Rothman questioning E=mc^2. Are the assertions made in the article valid? Are there comments by other physicists available?
  7. Several rinses with small amount of water each time is better than one rinse with a lot of water.
