    Graduate Accounting for Cosmological Expansion in Distance Measurements

    Some objects, Quasars for example have extremely high redshifts, and come from a time long past, and place far away. When determining distance on such large scales, how do you also factor in the cosmological expansion of the universe, meaning 10 billion years ago the universe was much smaller...

    Graduate I don't like Dark Matter and Dark Energy

    Earth is the center of the universe, all scientists agree, who are you to disagree... Plate Tectonics is crazy, why would anyone believe something like that? Scientists all agree it is wrong, who are you to go against them? Earth is warming only due to CO2, 2300 members of the IPCC agree, who...

    Graduate Detecting Anti-Matter: Can We Tell?

    The observed universe is matter, not antimatter. So no.. But.. One theory that is funny to think about, but in some ways I don't agree with basically states the universe was 50.00001% matter and 49.99999% anti-matter, over time they all destroyed each other and what is left is 0.00001% of the...

    Undergrad Size Limit of Comets: Understanding Kepler's Laws

    Yes and sort of... Size yes. Maintain, is a word not used often in astrophysics, since everything is measured in it's time to die. Any orbit can be maintained for a time, but how long?? Possible yes, but for a relatively short period. The one test we had on a comet showed it is very...

    Undergrad Size Limit of Comets: Understanding Kepler's Laws

    First we have to consider what is being asked. Elliptical Orbit - As stated above, most planets are in a slightly elliptical orbit, other items like what was named Pluto are on greater elliptical orbits. Comets as we see them in the inner system are on an elongated elliptical orbit. This is...

    Graduate Can Non-Cosmological Redshifts Explain Anomalies in Galaxy Interactions?

    I have a lot of problems with the standard model (dark matter/energy) and other made up non-since within. However I am not willing to just adopt a view on Dr. Arp or others view of the universe ad hoc. The Milky Way is an active Seyfert galaxies, and we know/detect small traces of anti-matter...
