1. ## What are you watching?

I purchased the complete 5 seasons of Combat! TV series from 1962 - 1967 and watch one episode every morning!
2. ## Hypervelocity Supermassive Black Hole

Would anyone like to calculate the number of megatons the blast would be from one million solar masses converted totally into energy? Here are some numbers I found: one megaton comes from 47 grams, so 21 megatons comes out of one kg, the sun's mass is about 2 x 10^30, so the explosion of the sun being totally converted into energy is (21 megatons) X 2 X 10^30 = 42 x 10^30 megatons. The energy from exploding one million solar masses would be about 1,000,000 X 42 X 10^30 megatons = 42 X 10^36 megatons. Did I get something wrong? The number I found for 10^36 is "undecillion." The directional impulse from the merger of quasar 3c186 was about 42 undecillion megatons. That is how you fire a cannon ball weighing one billion solar masses to a speed of 4 million mph.
3. ## Hypervelocity Supermassive Black Hole

The one Billion-solar-mass quasar 3c186 is off center in its' galaxy moving outward at 4.7 million mph (1305 miles per second)!! They think it got fired out of the galaxy when 2 supermassive black holes merged, after 2 galaxies merged. Can you think of more momentum than that? That will tear across the universe, like a bowling ball through pins, and maybe nothing will ever stop or divert it. "A supermassive black hole heftier than 1 billion suns has been ejected from the core of its galaxy by gravitational waves, a new study suggests. The monster black hole has already zoomed 35,000 light-years away from its galaxy's center, farther than Earth and its sun are from the core of our own Milky Way. And the behemoth is currently traveling outward at 4.7 million mph (7.6 million km/h)—fast enough for the black hole to escape its galaxy completely in 20 million years, researchers said." https://www.scientificamerican.com/article/gravitational-waves-send-supermassive-black-hole-flying/
4. ## Hypervelocity Supermassive Black Hole

Then that means about 0.1% of the mass, or one million solar masses, was converted into gravitational energy in a single pulse, like a cannon. During the merger, it was NOT like a balloon rocketing around a room, changing directions as the air blasts out.
5. ## Hypervelocity Supermassive Black Hole

Considering the speed it is traveling, does that not suggest that the SBH was accelerated by a single pulse impulse? (tell me how long it would take to convert). If the MILLION solar masses, that were converted into energy, took a long time to convert (minutes, hours, days, etc), the SBH would have been pushed in many directions and not sent in one direction at 4 million mph. I was thinking of a balloon flying around in all directions when you let go of it. Consider the merger of 2 ultra-massive black holes, for example two that are 20 Billion solar masses EACH, creating one of 40 Billion solar masses. Would that be considered a more energetic event than the acceleration of 3c186? When the gravity waves radiate out in all directions, the merger does not throw it out of the center of the galaxy. How much matter would be converted into energy during a merger of SBHs?

8. ## Hypervelocity Supermassive Black Hole

Would it be safe to say that the explosion that threw one billion solar masses to 1300 miles per second, was a short burst? Can we assume the explosion, of one million solar masses being totally converted into energy, took only seconds? Or a fraction of a second? Could the 2 SBHs that merged have themselves been spinning at high rates, but in different directions? Can anyone think of a more energetic event than a million solar masses being converted totally into energy, in a matter of seconds (besides the big bang)?
9. ## Hypervelocity Supermassive Black Hole

That means if a million solar masses, which is 10% of the mass of a Billion-solar-mass BH, is converted into energy in the instant of merger, that energy can accelerate a Billion solar masses to 4.7 Million miles per hour? How long does it take a million solar masses to be converted into energy? What's the diameter of the fireball? That sounds like some big firecracker!
10. ## Hypervelocity Supermassive Black Hole

What is the velocity the result of? Is it the 2 SBHs crashing directly into each other, or circling each other in an off-balanced way? One of them must be more massive than the other. So I was thinking of the 2 orbiting the other until they got up to a high speed when they combined, thus such an off-balanced merger throwing them together, out like an ancient sling shot. How else do gravity waves accelerate such a massive thing? Could it be the result of the interaction of 3 SBHs ? Maybe it won't "clear a path" but rather leave chaos behind it, yanking stars around? How wide a path of chaos can such a massive thing cause moving through a galaxy? Or is it moving so fast that it sneaks between solar systems before its' gravity can drag anything long enough in any direction? What would the quasar look like from a "safe" place? Such an extreme brightness, from the accretion disk, that you can't see what's happening. In fact you better not even look in that general direction.
11. ## Hypervelocity Supermassive Black Hole

Then the velocity of 3c186 is a combination of sling shot AND gravitational waves? Do the gravity waves act like a single impulse like a cannon shot? 1. How WIDE a path would 3c186 clear through that galaxy? 2. Does the accretion disk act as a drag on it moving thru its' galaxy? 3. How much drag would stars, gas, and dust have on it? How much will it slow down? 4. It may pass thru one or two more galaxies before it embarks upon a voyage into a void. A great void will be its' final destination. While it is passing thru the void, would there be enough atoms in the void to create a small accretion disk or a comet-like tail? 5. Would virtual particles create an accretion disk in the void? 6. What is a safe distance to observe it from? That's what I'm talking about. What would it look like clearing a path through a galaxy?
12. ## Hypervelocity Supermassive Black Hole

Could anyone please calculate the radius of a one-Billion-solar mass black hole? That math is beyond me. Suppose there were civilizations living in the galaxy where quasar 3c186 is on a rampage. Could any survive such a galaxy merger and resulting black hole merger? Could there be a safe place on the other side of the galaxy? What would it look like from a safe distance? Imagine that thing clearing a path through our galaxy. How many solar masses could it absorb in a day or a year? What masses of black holes can create a one-Billion-solar SBH moving that fast? Our galaxy's SBH is only 4 Million solar masses, which is tiny in comparison. Quasar 3c186 is 2500 times as massive as our SBH. 3c186 would tear though the center of our galaxy without hardly noticing our black hole and not slowing at all. The article says 3c186 was launched by gravitational waves. What about centrifugal force? Wouldn't the off-balanced merger act like a sling shot?
13. ## How does the Trump era end?

Yes, all those things are just "Trump being Trump" to the 1/3 or Americans that are suckers for celebrity, and like a cartoon character, political Rambo. Russia doesn't matter because the Russians got their guy elected. They say thanks to Russia. You made an interesting point about Tax Time this year. By the end of April, his base, those 1/3 of Americans that still think he's cute, will wonder why they didn't save thousands of dollars? Remember how he boasted his tax plan was for the middle class, not the wealthy? "It's not good for ME, believe me!"
14. ## Hypervelocity Supermassive Black Hole

You think it will probably not ever encounter anything of significance? It will head unimpeded towards the edge of its' supercluster. Beyond that the expansion of the universe overtakes its' own relative speed. It will never make it to the next supercluster?
15. ## How does the Trump era end?

He gets offered a program on Fox News which prompts him to resign. His show on Fox News has lots of "executive time" and hot, young women for "aids."
16. ## Hypervelocity Supermassive Black Hole

Since stars are so far apart, it seems like it will meet very little resistance until it approaches the edge of the galaxy. Only as it nears the edge of its' galaxy will the combined gravity of the galaxy pull on it from behind to slow it. A Billion solar masses compacted into such a small area will ignore everything else in the galaxy. Many galaxies have hundreds of billions of solar masses, so as 3c 186 passes by OTHER galaxies it will feel some gravity slightly bending its' path, right? Other galaxies may even accelerate it. Anyone want to try to explain its' possible path? I think nothing can ever stop it, unless it slams into something as massive as it is, and there are not many SBHs that massive around. If stars are so far apart that they will almost never meet, supermassive black holes are FAR more scarce. Very unlikely anything will ever stop it, it seems to me.
17. ## Q about black holes (split from Black Hole Energy Distribution)

If a black hole is not feeding, then would inside the event horizon be a total vacuum and all energy contained within the singularity? A non-feeding black hole would be just a singularity and its' gravity?

22. ## Bill Maher Vs Ann Coulter [debunking wall arguments]

We are discussing how Trump's fiction is acceptable to 1/3 of Americans. Ann Coulter is Trump's advisor and a spokesperson of the Trump followers. I am trying to discredit the idea that "Trump's wall" will solve border problems. This is intended to analyze her arguments to discredit them. She says a lot and gets away with a lot. Her arguments are not adequately discredited. Bill Maher could not address ALL Coulter's fiction. She, along with 1/3 of Americans, think: (1) Trump is cute. (2) Russia doesn't matter. (3) The "wall" is the most important issue, and the US shuts down again in a couple weeks without the "wall."
23. ## The Border Wall or Fence

Recently Trump demanded his "wall" again, and said the $5.7 Billion was an "installment." His definition of "wall" is something beautiful to behold. A nice, tall, strong, see-thru "wall" of steel slats. And IT is not there already. What is there now is called a "scrap metal fence." Trump declared the current "scrap metal fence" is actually 95% effective. What's so bad about 95% effective?! Just extend that 95% effective scrap metal fence. How much will that cost? Later he said the scrap metal fence is "not doing the trick." Which means it should be 99% effective like his steel slats. The scrap metal fence is not beautiful enough. When inspecting the border-wall samples near San Diego, Trump noted how the scrap metal fence is cut thru and repaired leaving scars that Trump remarked "doesn't look so good" in his mob-boss tone of voice. This means he wants to tear down the ugly scrap metal fence and replace it with big, tall, beautiful, strong, powerful steel slats, and put his name on it in big letters. That is a project costing$50 to $100 Billion and the$5.7 Billion is only for starters. One third of Americans are with Trump 100%, even if he quits talking about his "wall." Doesn't matter what he does for them, even if he shoots someone on 5th Avenue. One third of Americans actually like his brash behavior. In one third of American households that kind of behavior is considered masculine and therefore CUTE!! One third of Americans LIKE his antics. My brother voted for Trump. He is a Rush Limbaugh fan and for 8 years complained about Obama. "Obama wants to be a dictator." "I hope they trash Obamacare!" Etc. Now he is silent about Trump and we don't talk politics. When I asked him if he thinks Trump is obnoxious, he replied "no." I am amazed that my dear brother doesn't think Trump is obnoxious.....and to me he is the definition of obnoxious. To me his is forever an 8-year-old boy who acts like the tough guys he sees in movies, puffing his lips out, thinking it looks tough. Nobody told him it looks weird, contorting his lips in an exaggerated manner as if to make sure lip readers can follow him, locked in his delusion thinking he is smarter than he really is.
24. ## Trump's Open Admission of Witness Intimidation

There is such a vast record of Trump's thoughts given in his tweets, that a compelling case can be made that in Trump's mind HE is the ultimate agent of the "truth." Will that work in a court of law? Probably not, but in the court of public opinion it can lead to a political resolution.
25. ## Trump's Open Admission of Witness Intimidation

Cohen's lawyer, Lanny Davis, said Trump has been threatening Cohen, as well as suggesting that his father-in-law could be investigated for unspecified crimes because he is a wealthy Ukranian and therefore must be involved in organized crime. “And not only was he intimidated, but he believes his family also has been intimidated and threatened,” Davis said. Trump denied the claim and told reporters that Cohen was “threatened by the truth.” Trump admitted to reporters of witness intimidation with his response to the question "Are you threatening Cohen and his family?" Trump confirmed a threat exists and replied that Cohen was "threatened by the truth." In this context Trump regards himself as the "truth" in the threat. Cohen and his family are threatened by the truth (Trump). This looks like thinly-veiled, out-in-the-open witness intimidation. Add this to the list of reasons to impeach.
