Where did they get their data for the number of protestors because it was actually 4 - 6 million protestors. Article with link to the actual population data

I just had a nice chat with one of the security guards and she told me to stay safe with a smile on her face. That's the second surprise I've had today.

I drove by a group of people in a small Texas town with protest signs. I never thought that would've happened, but I've been proven wrong. It'll be my turn in a bit.

It's a bit finicky to assign the buttons on the initial retropie setup, but after that, it's good.

I grabbed my phone as I watched it hop, branch to branch, to the top.

Ok. I didn't know. Just try to be safe .

That's some serious stuff. I wouldn't fully trust that guy if I were you, so be prepared for the worst if you're seriously committed to this. If not, I'd find a way out, if possible.

 

Observations of our neighbouring galaxy, Andromeda, made using ESA’s Flyeye telescope.

Andromeda appears so large in Earth’s sky that in angular size it is six times the diameter of the full Moon and it can be seen with the unaided eye in dark skies.

For a dedicated astronomical telescope such as the NASA/ESA Hubble Space Telescope, viewing the whole Andromeda galaxy requires stitching together hundreds of individual observations. This Hubble image of Andromeda, for example, took over 10 years and 600 snapshots to make.

Flyeye, on the other hand, is a survey telescope designed to see as much of the sky at once as possible, and to rapidly scan for new near-Earth objects. This image of Andromeda takes up just one sixteenth of the telescope’s full field of view.

The image was acquired during the telescope’s ‘first light’ campaign by combining 16 exposures, each of 30 seconds.

I'll post the finished project and details after I've assembled it.

Great work. To me, these are tears of joy. Thank you for sharing.

 

TL;DR

Conclusion

We have searched for evidence of the effect of gravity on the motion of particles of neutral antimatter. The best fit to our measurements yields a value of (0.75 ± 0.13 (statistical + systematic) ± 0.16 (simulation)) g for the local acceleration of antimatter towards the Earth. We conclude that the dynamic behaviour of antihydrogen atoms is consistent with the existence of an attractive gravitational force between these atoms and the Earth. From the asymptotic form of the distribution of the likelihood ratio as a function of the presumed acceleration, we estimate a probability of 2.9 × 10−4 that a result, at least as extreme as that observed here, could occur under the assumption that gravity does not act on antihydrogen. The probability that our data are consistent with the repulsive gravity simulation is so small as to be quantitatively meaningless (less than 10−15). Consequently, we can rule out the existence of repulsive gravity of magnitude 1g between the Earth and antimatter. The results are thus far in conformity with the predictions of General Relativity. Our results do not support cosmological models relying on repulsive matter–antimatter gravitation.

The abstract from their article

It is commonly believed that our own Milky Way is on a collision course with the neighbouring Andromeda galaxy. As a result of their merger, predicted in around 5 billion years, the two large spiral galaxies that define the present Local Group would form a new elliptical galaxy. Here we consider the latest and most accurate observations by the Gaia and Hubble space telescopes, along with recent consensus mass estimates, to derive possible future scenarios and identify the main sources of uncertainty in the evolution of the Local Group over the next 10 billion years. We found that the next most massive Local Group member galaxies—namely, M33 and the Large Magellanic Cloud—distinctly and radically affect the Milky Way–Andromeda orbit. Although including M33 increases the merger probability, the orbit of the Large Magellanic Cloud runs perpendicular to the Milky Way– Andromeda orbit and makes their merger less probable. In the full system, we found that uncertainties in the present positions, motions and masses of all galaxies leave room for drastically different outcomes and a probability of close to 50% that there will be no Milky Way–Andromeda merger during the next 10 billion years. Based on the best available data, the fate of our Galaxy is still completely open.
