    Many I talk to have a feeling of comfort when discussing the expanding universe because the alternative is so final. I always felt disappointed in the expansion of the universe because if there was a Big Crunch in our future, it would also mean the universe would get closer and become easier to explore. Certainly not in our lifetime but a big crunch would not be in our lifetime either.

    The other problem in the far distant future of an expanding universe eludes to the problem that observation itself will become more difficult as the universe expands away.

    Ofcourse there may be something wrong with the expansion theory and scientists may discover the opposit in the future.

    I read how extremely massive objects like black holes can actually warp and drag the surrounding space-time. For each X-ray burst from a black hole hot spot, the observer will receive two or more flashes separated by a constant interval, so even a signal made up from a totally random collection of bursts from hot spots at different positions will contain an echo of itself. A light echo.

    Heard Alpha Centauri is most certainly harboring detectable, Earth-like Planets. Now this is most interesting because life in our solar system, if exists, did so in our past. The odds of life in another solar system must be higher vs hopes of life in our solar system. Personally I am not very interested in proving life on earth came from mars or Titan harbors little vonagut bugs. ok ok - i know we learn from it all but i want to take bigger steps. Mars??? let it be...

    The discovery of the asteroid crator off the coast of Cancun in the Yukatan is fascinating. The California baha area has water depth of around 300 feet but there is this large hole there with depths of 2,500 feet. My mind wonders.

    Using a computer model, (i know this has been done to some extent) could we reverse the orbit of the moon to track it back and discover its true origin and how it came to be in earths orbit?

    oh yeah, one more thing, if our moon (which has no name-thats wierd) is a result of the earth colliding with another object in the past, would it be safe to assume that many large objects were sent speeding of away from the earth and would it also be true that these objects are in an orbit somewhere in the universe speeding along and would it also be tru to say the the earth, where this orbit originated from is square in it path on its return visit?

    a couple of thoughts I had relating to your posts

    -on the note of Alpha Centauri, there was a program on the Science channel tonight, or last night or something that was about the likelihood of life on other planets
    -One common theory about the extinction of the dinosaurs is that it was caused by the object that created the crater near the Yucatan Peninsula
    -Our moon's name is Luna
    -There were probably more large objects expelled from the collision between Earth and the other planet (can't recall the name), but if they were shot out by the explosion, it doesn't necessarily mean it will come back directly to it's starting point (if that is what you mean)

    The show is on tonight, 10 PM Pacific.
    Of all the wonders in the universe, none is likely more fascinating and complicated than human nature.

    "Two things are infinite: the universe and human stupidity; and I'm not sure about the universe."

    "Great spirits have always found violent opposition from mediocrities. The latter cannot understand it when a man does not thoughtlessly submit to hereditary prejudices but honestly and courageously uses his intelligence"
