Your scenario doesn't make for exciting TV. Remember the movie The China Syndrome ? After Three Mile Island the general public thought a reactor meltdown would penetrate through the Earth and reach the opposite side of the globe.

If you country's borders had been re-drawn by Prussians and Russians numerous times over the last several hundred years, and sometimes, totally eliminated )… If your country had been attacked by the Nazis to start WW2, and then been occupied by the Russians for half a century... If your country was witnessing the goings on in the Ukraine, and the Russians were again starting to flex their invasive muscles... You might be paranoid too.

Officials at Glacier National Park making changes...
MigL replied to et pet's topic in Climate Science
If I may... Peppering Et Pet with numerous negative points is totally inappropriate. He is correct ! There have been numerous changes in the climate of this little blue planet over the preceding aeons. Climate change HAS occurred, and will continue to occur; and glaciers will come and go ( as they did in my area of the world 12000 yrs ago ). And he has provided support for his assertions that the causal factors are due to the changes of the Earth's orbit, and the combined effects of three cycles with some secondary factors like albedo, currents, and even volcanic/asteroid activity. What we should be discussing instead is ANTHROPOGENIC climate change, and how to alleviate that problem. We have no control over the Earth's orbit, but man-made climate change is a different topic -
How would I know if I had been brainwashed
MigL replied to RealEmotion's topic in General Philosophy
If you have a dirty mind, do you need brainwashing ? -
Brakes have proportioning valves that apply dissimilar hydraulic pressure front to rear, and take the vehicle's weight distribution into consideration. Front heavy vehicles ( usually front engine/transmission/drivetrain ) will go through several disc brake pads on the front axel before the rear ones halfway worn.

Calculation of the 11-year period of solar activity. Other reality
MigL replied to Hamster22's topic in Speculations
Must be the 'new' way of doing science... You pull a bunch of unrelated numbers and constants out of your a*s, put them together in a way that gives the approximate result you're looking for, and call it a breakthrough. -

I'd suggest moving to Trash... -
I fear we've gotten a little sidetracked. Chicken shit is far from Theresa May. Or is it ?

Does anyone keep in touch with Ten oz ? He logs on sporadically but, hasn't posted in a month. Hope everything is OK with him and family, and he's just taking a breather or working a lot. He can push my buttons, but I have great respect for him. And frankly, the Politics Forum isn't the same without him.

That can't be right,,, D Trump claims there were no protest rallies. !

Seems that even places with strict gun laws aren't immune from idiots wanting to hurt/kill other people. Seems so much more shocking when the news comes from a place other than the USA. My condolences to our Australian friends, BeeCee, Hyper, and other members who live down-under.

Looks like 'our' idiot, D Trump, has jumped headfirst into the Brexit controversy. He expressed an interest in T May staying on, refusing to meet with opposition, and promising 'sweetheart' trade deals with the UK once they leave the EU. Like anyone trusts D Trump when it comes to trade deals...

The expression E=mc^2 is not complete. It only considers particles where m is the rest mass, and as such, doesn't apply to massless particles like photons.

If you can be a world class player in your 70s, it CANNOT be a sport. Or it could be just jealousy... I used to golf, and had a decent drive, but now I only see with one eye, and have no depth perception. ( my putting is now great )
-
Changing one property, changes a lot of others. Taking away a particle's inertial mass constrains it to move at c and have no valid rest frame. So I don't really see how you can call them different manifestations of the 'same thing'.

You would not get FUSION no matter how much you compress a terrestrial planet. Fusion can only releases energy up to element 26 ( Iron ), after which, energy must be supplied to bind nuclei together. Terrestrial type planets have iron/nickel ( and other heavy elements ) cores. ( And yes, FISSION does happen to the heavy nuclei to release heat energy ) Maybe if you were to compress Jupiter... We can model the interior of a BH's event horizon. But only according to currently accepted mathematical models. Thesemodels are incomplete ( as they do not take quantum effects into consideration ) and untestable ( as we will never get information back out of a BH ).

Sodium hypochlorite and food / brewing safety
MigL replied to JimmyLasers's topic in Applied Chemistry
I'm not a chemist either, but ( I'm ashamed to admit ) I work with chemicals. And I don't understand the benefit of using an oxygen scavenger for disinfecting. Can you elaborate John ? I make wine; and sodium metabisulphite can be used to stop fermentation ( for obvious reasons ) ( Wouldn't the most benign disinfectant be dilute H2O2 ? ) -
Congratulations ! I hope this small success is worth the acid burns and the shakes/numbness/mental problems you'll get from mercury poisoning.

Can gravitational waves be affected by matter?
MigL replied to Ghideon's topic in Astronomy and Cosmology
Gravity is the geometry of space-time. Gravitational waves are the 'ringing' or 'ripples' emanating from a sudden change to this geometry. These changes, like all other information are constrained to travel at a specific speed, c , otherwise causality is violated. As such, they would behave like EM waves ( as per your link Ghideon ). The BH would act as a 'sink', absorbing all intercepted waves, and modifying the path of approaching ones. -
Interesting, BeeCee. But the rotation didn't just slow down to current levels. It actually went retrograde. I could see this for an outer planet, orbiting out of the plane of the ecliptic, suggesting capture. But Venus orbits close to the Sun, and in the plane of the ecliptic, suggesting it was formed from the primordial gases/dust that made up the solar system. Tidal forces could not have made its rotation retrograde in that case. This is just a theory. But my money is still on the collision theory.

Well this got ugly quick. I could understand it if you guys were Democrats and Republicans. But you Brits are supposed to be even tempered and calm... Relax, things can't get much worse than they already are.

Any 'one time' electoral decision, that doesn't allow the electorate to change its mind afterwards, is commonly called a dictatorship. Spare us all the political drama and have another referendum already. We have enough drama on this side of the pond.

My thoughts on the matter, BeeCee... Once a rotating mass collapses to a BH and associated event horizon, classically, there is nothing that actually spins. The event horizon is a mathematical construct, and ( at least classically ) everything else associated with the BH is in the singularity. The conserved angular momentum can be considered intrinsic, similar to quantum particle spin. All other effects would have to be external ( the accretion disc, maybe ) to the event horizon, as lines of force ( magnetic field lines ) cannot travel from inside the EH to the exterior. I had thought that frame dragging might siphon off angular momentum, but I'm not so sure. Any loss of mass would reduce angular momentum, but any existing BHs are gaining mass and it will be a long time before they radiate appreciable quantities of Hawking radiation to start evaporating. ( stellar BHs, the smallest we know of, are way colder than the CMB, and are gaining mass ) Any massive collisions ( other BHs or neutron stars ) that could reduce the angular momentum, would tend to INCREASE the BH's mass-energy and so, the extent of the event horizon. Certainly not reduce it.

I have read reports that the 1919 solar eclipse observations were inconclusive, and may have even falsified results to make them seem more conclusive. Sir A Eddington considered himself one of the 'five' people in the world who understood relativity, and may have had vested interests. ( the more I read about this guy, the more he seems like a pompous ass, although a good scientist ) Subsequent ( more accurate ) tests for the bending of light in a gravity well DID prove conclusively the amount of bending predicted by A Einstein.

What's making it slow down ? ( also, the 'outer' horizon will shrink as the BH's angular momentum increases )
