You mean they don't eat or drink unitl they have evacuated? I don't think so. The fact is that they announced early in the program, maybe you weren't there but I was, that they did it to save weight. Recycled water comes from water ingested. Why not eat good food and drink good juice first? Why...
Why do our space "scientists" send Tang and other dehydrated food into space; to save weight? We take along the water needed to rehydrate the food. Where is the weight savings? In grade school we used to joke about the guy that sent an overcoat to his friend but cut off the buttons to save...
Impractical?
Cities and artifacts were moved for Aswan; the benefits are enormous. Three Gorges is moving thousands of people; it will be worth the effort and the uprooting will be forgotten in a few years. Just wait until we are fighting internal wars over water in a few short years. We are...
Corrections.
3. Is a proposal is made to build a dam for whatever reason an backlash occurs to not destroy the environment, the wild waters, the endangered species, et al. If we were to propse Washington D. C. today we would never leave the courts. Back in them days there was a marsh and canals...
1. Our solution to floods seems to be locked in on building levees thereby constricting the free flow of water and increasing flooding when they are breached. When I went to school we were taught that seasonal floods enriched the farmland.
2. By drawing more water from the water tables than...
Expansion, yes.
It is accepted that our solar system is receding from VIRGO so expansion is not limited to just galaxies. It is also assumed that "space" contains a force that is probably causing the expansion. I think of it as negative gravity but that is just my way of understanding it.
I...
Collisions.
I understand local groups but that just means that they are closer to each other than to other galaxies and groups, and bound by mutual gravity. There are still collisions of galaxies with other galaxies and collisions of other objects with each other so there is movement other than...
Thanks loads.
Thanks to russ-watters and chroot. In one day you have cleared up a problem I have had for a long time. I am glad I found a forum with people of your caliber. So many times you get flippant answers from people that just want to "rag" you for not being as knowledgeable as they...
WMAP?
What is WMAP and how does it work? I have always been troubled with the red shift method because it doesn't seem to take into account the movement of our solar system in relation to the observed object. If we are moving in the opposite direction from the observed object that would...
When the media report on distant objects and state that the light from that distant object was emitted 10 billion years ago, for example, I wonder where the object is now, and more important, how long did it take the object to arrive at the place where it shined. How is the transit time from...
Colgate University info
Thanks Radio Wave and also you Infrared Wave for enlightening me.
In the interim I found a good explanation on the Colgate University site. They compared it to a cookie with raisins; as the cookie expands the raisins move apart. I can understand the analogy but it...
Not an explosion?
If it was not an explosion then why is everything moving away from everything else? Why is there a controversy about it recollapsing on itself? Why is it called a "bang"? What else is a bang?
You haven't answered a question; you have elicited more.
When there is an explosion on Earth the void created is quickly filled with Earth debris. When we view an exploding star there is no debris (understandable) but there is a large bubble with a void in the middle. Why is the universe NOT shaped like a large bubble with a void since the accepted...
