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.
-
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?

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?

TFG or That Florida Guy? Either way, can the GOP win in 2024?
Airbrush replied to Phi for All's topic in Politics
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.” -
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?
-
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.

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?

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?

"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?

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.
-
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.

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?

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

Conditions on Earth are changing faster than people's minds change. It takes generations for significant human changes. We don't have time for that. We need to adapt quickly or self-destruct.

How can a big bang expand to an infinite size?
Airbrush replied to Airbrush's topic in Astronomy and Cosmology
Most of this is beyond my understanding. "Time and energy are Fourier conjugates (or more generally, spacetime and energy-momentum) and cannot exist in the physical reality without each other. In other words, GR states that spacetime is the field produced by matter just like the electromagnetic field is produced by charges. Vacuum solutions are unphysical, they don’t exist in reality. Their flaw is that the equations are solved without realistic physical initial conditions. This approach and resulting solutions are physically meaningless." But then there is also this from the same source: "No, general relativity doesn't make any claim as to whether matter must exist or not. In fact, the simplest of the solutions to the Einstein equations are vacuum solutions. For example, the Kerr-Newman blackholes and their special cases such as the Schwarzschild blackholes and Kerr blackholes. The dimensionality of spacetime is still 4D in these solutions with one dimension being time-like." general relativity - Does Time Require Matter to Exist? - Physics Stack Exchange -
How can a big bang expand to an infinite size?
Airbrush replied to Airbrush's topic in Astronomy and Cosmology
I was wondering if time can exist without matter? This is what I found: "GR states that spacetime is the field produced by matter just like the electromagnetic field is produced by charges. Vacuum solutions are unphysical, they don’t exist in reality." Does that mean that if the big bang has a finite size, the outer 3d limits of the expansion could be expanding at ANY speed (assuming there is no infinite speed), and beyond that limit could be a region of no matter and therefore no spacetime, just "space" if you will? No more spacetime, just space, until you encounter another big bang coming from another direction? I thought one way to explain an accelerating expansion of the universe is our observable universe is located inside a great void, like a bubble surrounded by unimaginably great masses pulling our region of spacetime apart from all directions. -

How can one assume that photons have any mass at all? I thought photons were energy and that is why they travel the speed of light. How could any mass travel light speed? -
TFG or That Florida Guy? Either way, can the GOP win in 2024?
Airbrush replied to Phi for All's topic in Politics
Yes, "woke" as opposed to unconscious. Dictators thrive on unconsciousness. The level of mind-control is astounding. Time to vilify education and awareness. So GOP voters will CLAIM items of interest because they can't state the truth, that they are simply enthralled by an entertaining celebrity, who struts around like a pro wrestler, and cracks wise about the evil other party. If TFG were to state "inflation is not an issue, and the thousands at the border is nothing, and wokeness is no big deal" his cult of personality will turn on a dime to not care about those things either. They can't be deprogrammed because their source of news is narrow, by choice. -

Topics of most interest to GOP voters: 1 Controlling Inflation - 53% US inflation has been trending downward and GOP need to be made aware of this. Unusually high worldwide inflation followed the Covid pandemic broken supply chains. Worldwide inflation averaged over 8% for the year 2022 (US averaged only 6.5%. US averaged 3.9% for 2023 so far, and down to an average of 3.3% over the past 6 months.) Inflation Rate - By Country (tradingeconomics.com) Historical Inflation Rates: 1914-2023 (usinflationcalculator.com) 2 Controlling Immigration - 36% 3 Fighting Liberalism & Woke Agenda - 25% 4 Able to Beat Biden - 25% "Of the topics that we asked about, [GOP] voters were most concerned about “getting inflation or increasing costs under control” (53 percent of respondents selected this issue),...Other issues that were top of mind for voters were “controlling immigration” (36 percent), “someone fighting against liberalism and the woke agenda” (25 percent) and “ability to beat Joe Biden” (25 percent)."

"If you 'looked' far enough away, you would 'see' the back of your head." But would you see your back only if you looked in ONE direction, or every direction? Would all straight lines of sight circle around to you from every direction? -

Trump will win in 2024 IF Biden does not deal significantly with the border issue. If Biden would deal with the border, that will neutralize the GOP's biggest weapon against him. Or they will call him "Open Borders Biden." -
How can a big bang expand to an infinite size?
Airbrush replied to Airbrush's topic in Astronomy and Cosmology
There are many functions that head for infinity as a numerator approaches zero. Try to apply that math to the actual big bang. Look at the biggest picture possible, the observable universe. It resembles a homogenious sponge-like structure of galaxy clusters. If you had to bet on only one or the other, what would you bet on? 1 That homogenious, isotropic structure extends like that all the way to infinity? Or 2 That structure changes over distance, becoming scarcer or denser?
