  1. So that means the US did so much work, and spent so much money, to prove the bomb was possible, but once the word gets out how to build it, even a poor country could build one.
  2. Very interesting. I like your explanation. Then you said that "something" maybe some kind of sub-nuclear particles possessed the energy. Let's work backwards. Now we have matter. Before that, matter was in the form of energy, sub-nuclear particles possessed energy, and we don't know what was between that and the start of the big bang. Right?
  3. The world's physicists were not aware of the bomb test success. Physicists cannot build a bomb. It takes a Manhattan Project. The test could have been covered up and the US would get into an intelligence operation to prevent other nations from developing the bomb. Besides no other nation had the money for their own Manhattan Project. Are you aware that the project was secret? Or were the Soviets already inside the Manhattan Project, taking notes, before the A bombs were used on Japan? Maybe the Soviets already knew how to build the bomb and did not need to spend on their own Manhattan Project?
  4. Yes the GOP CAN win in 2024. The Trump Cult works! "The people following Trump see him as a king Cyrus figure, not a prophet. He is a sinful king that God supposedly uses. Putin is at the top of puppeteers of the Cult of Trump. Trump is a weapon of a foreign adversary to usurp America. Putin has an agenda. The Soviet Union fell and Putin is committed to helping America fall. Putin has used religious right activists at great psychological advantage because of our ignorance of the fact that psychological warfare is being waged on us. Michael Flynn and Steve Bannon are part of this. It is warfare aimed at causing confusion, uncertainty, doubt, overwhelming people, attacking experts, attacking science, attacking institutions. Because if you disorient people enough, they are going to be responsive to certainty of an authority figure who says “Trust me, I’m going to make America great again.”
  5. Please explain why. You believe that the existence of the bomb could not be covered up? Why not at least stall such a bomb to the rest of the world?
  6. Thanks for your explanation. But what if the "surface" or skin of the balloon, had a thickness of over 100 billion light years? Then the expansion would resemble what we can see, no voids would be seen, and we would not know the direction of the expansion. Are you suggesting that the big bang was not an expansion of energy? First there is energy. Much later, after it cools down, a huge amount of energy congeals into a small amount of matter, E = mc2, so E/c2 = m.
  7. To show off to the world what the US could do? Japan was already beaten. We also found out that the Nazis never developed anything close to an A bomb. Japan was already totally cut off from the world by US submarines and air force. No more imports so they were on the verge of starving. They were also having their cities systematically destroyed by huge B29 incendiary strikes, like the one that killed 100,000 people in Tokyo IN A DAY. All that happened by using the A bomb on Hiroshima and Nagasaki was to REVEAL to the world that such a weapon EXISTS. What they should have done, IMHO, is realize that nobody needs to know about IT, and that IT should be covered up so nobody else can create an A bomb. There should have been a HUGE, Manhattan-Project-sized, intelligence operation to do everything we can to make sure that no country can create such a bomb, except for the US. The US would TRY keep the A bomb a secret as long as possible. That would have saved so much money. Of course you can't keep something like that a secret forever, but at least stall it as long as possible. Or is this a naive proposal?
  8. Yes, and the big bang was a rapid expansion of energy that cooled and condensed into matter. Can you describe this more? It is hard to imagine how more than one infinite universe could co-exist in a natural way. We may arbitrarily divide an infinite universe into any number of sections, each section extends to infinity in one direction, but that is not natural. How can a finite-sized universe not have a center or edges?
  9. "Daylight saving time was first introduced in the United States in 1918 under the Standard Time Act as a measure to save on fuel costs during the First World War by adding an extra hour of sunlight to the day.... "In 2005, Congress amended the Uniform Time Act to expand daylight saving time to the period in effect today: Starting on the second Sunday of March and ending on the first Sunday of November, according to the Congressional Research Service. This move was again for energy saving purposes. "A Department of Energy study following the amendment’s implementation found the extra four weeks of daylight saving time saved around 0.5% in total electricity daily in the U.S., equaling energy savings of 1.3 billion kilowatt-hours annually." Who invented daylight saving time? Time change purpose and origins (usatoday.com) I don't care which one, standard or DST, just stay with one. Anyone in favor of continuing to change the time twice every year?
  10. What is the evidence that the big bang was not an explosion? What is the likelihood that the expansion we are able to see continues to infinity (assuming a flat universe)? I propose that even scientists are not comfortable with very large numbers. The number of Planck volumes in our observable universe is less than 10 to the power of 200.
  11. You sound so confident. I don't think anyone knows if the big bang was an "explosion" or not, and we don't know anything about a pre-big bang vacuum. With eternal inflation those don't work. With a multiverse of universes what do you find between universes or big bangs? They call it the "bulk." Is that a vacuum? What we call THE universe may be only ONE region of expansion and we like to project that to infinity because very large numbers are beyond us. What does our big bang look like Graham's Number of light years away? We don't have a clue. We don't know if the "big bang" happened LITERALLY everywhere. We think the OBSERVABLE universe (big bang) began as a tiny dense region. Light has a fixed speed THROUGH space, but we don't know how fast light moves far beyond our observable horizon. Cosmic inflation is much faster than light speed. Everything you are talking about refers to our observable region of our big bang. There certainly MAY be a central region of our observable portion of our big bang.
  12. Here are a few of mine: 1. "SAGITTARIUS A STAR" This title bothered me for many years until I figured it out. Why do they call a supermassive black hole a "STAR"? Black holes are NOT stars! Then I finally realized it means "Sagittarius A ASTERISK." That is dumb. Call it "Sagittarius A Hole". 2. Why not call: Dark Matter = Unknown Gravity? Why not call: Dark Energy = Space Energy? Because no can do, we must stay with the original racist terms. 3. Why RPMs? That means either "revolutions per minute" or "rounds per minute." Call it something people, such as I, can relate to. Say "RPS" or "revolutions per second" and "rounds per second" to save your reader from the doing math, dividing by 60, to figure out how fast that is. A second is very easy to understand. A minute is way beyond comprehension, unless you are a science expert. Don't get me started with "megaparsecs" or "astronomical units" when you could easily use "light years" or "light days" or "light minutes" which are FAR EASIER for most people to visualize. 4. Pedestrians who leisurely cross the street paying no attention to cars waiting for them. Any others?
  13. In a multiverse model there may be multiple, or an infinite number of, big bangs. In that case each "universe" is finite in size, has a center, and edges expanding outward. The outer edge may have ANY shape and be moving at ANY speed since the edge is not constrained by space as it expands into the "bulk." "In the bulk model, at least some of the extra dimensions are extensive... and other branes may be moving through this bulk." Brane cosmology - Wikipedia
