No. Because then you have to travel the 25 000 ly TO sag a* BEFORE using Oberth effect (and then back). AND spare fuel to use the Oberth effect at sag a*, which means that you´ll for the first leg be travelling slower than if you were not planning on using Oberth effect.

It is surprising and somewhat unusual but it is one of the relatively notable facts about chemistry of phosphorus. Likewise, phosphorus has hypophosphite H3PO2 which is importantly a monobasic acid. But the underlying logic is that while the low coordination numbers of P (and S) prevail in lower...

Precipitation data and the relevant temperature data: Article Figure 2: 4xPIC summer and winter temperature maps Article figure 3: 4xPIC and 2xPIC monthly temperature and precipitation averaged over regions Article figure 5: 2xPIC summer, winter and annual temperature and precipitation profile...

You cannot recover all of it, by Carnot laws of entropy. When the heat spent on friction raises the temperature of air only slightly above the original/ambient temperature, only a small fraction of frictional energy can be recovered. However, when the heat is spent on friction at temperatures...

As for permanent loss of energy, consider that energy spent on heating the air by viscous friction is recoverable on expansion. Energy gets lost when it is removed from the hot air by conduction or radiation, which depends on the goodness of heat insulation. Or when it is spent on endothermic...

So far I have addressed exclusively temperature. However, the modelling also covers precipitation. Yet, again, in inconveniently inconsistent way. Note that some data are in Supplement only.

Another part of the problem is, can the OP usefully critizise and check the AI results? AI can even hallucinate. Searches cannot hallucinate, but they can quote in wrong context. Then again, so can humans.

Missed to correct it - centre of the neutron star. A neutron star should be a fairly strong gravitational lens, like the outskirts of a black hole - but the neutron star interior might have the waves passing directly through the interior, while black hole event horizon might absorb gravitational...

How would a tight (tight enough that the inner pair is "visible" as a source of gravitational waves) eclipsing ternary system of compact objects (all three being black holes or neutron stars) "look" like in gravitational waves? Even if it is unlikely to happen in real astronomy (I can see some...

May I offer comparison of experiments to reflect on? 1) Heat a ring while stopping it from expanding, as in your OP vs: 2.1) Heat the ring while free to expand in any direction, then as a separate step: 2.2) Compress the outside of the hot ring until its outer size matches the original outer...

Is it then electrons which are detected, though? Bells routinely ring in frequency range of common astronomical gravitational waves. The vibrations of a ringing bell, like all confined vibrations, are necessarily quantized. If you detect a bell rung by transition due to the bell absorbing of a...

The magnetic moment of an electron is about 700 times bigger than that of a proton. Both have spin 1/2, but in equal external magnetic field, the energy of an unpaired electron is about 700 times bigger than the energy of an unpaired proton. (All nuclei other than the triton have magnetic...

How would that no-analogue climate in terms of temperature amplitude by itself affect the vegetation of interior Antarctica? I suspect that most plants would not be limited by temperature amplitude itself. What limits the diversity of modern vegetation of Lena and Mackenzie valleys - vegetation...

In which directions did initial rise of water propagate, in which directions initial drop?

Something that the article hints at... Section 4.1: ...but does not outright state, is that the Antarctic interior Eocene climate as modelled is a no-analogue climate compared to the modern one. Consider Figure 5, the 2xPIC case. Sadly, while the longitudes are expressly labelled on the images...
