Amazing

[Q&A+] Alternative Dyson Spheres, Vera Rubin's Data, Source of Magnetars

Q: What if the laws of physics are not uniform across the universe?

This is a possibility, but current scientific understanding assumes the laws of physics are the same everywhere based on extensive observations.

[Q&A+] Alternative Dyson Spheres, Vera Rubin's Data, Source of Magnetars

Q: Could we look at the neutron to neutron star merger witnessed by LIGO and see if it became a magnetar?

The lack of a specific radio signal post-merger means they couldn't confirm if it turned into a magnetar, but it could also be a heavier neutron star or black hole.

[Q&A+] Alternative Dyson Spheres, Vera Rubin's Data, Source of Magnetars

Q: How does the mass of the Milky Way galaxy's supermassive black hole compare to the mass of other galaxies?

The supermassive black hole at the center of the Milky Way is about 0.1% of the galaxy's total mass, which is consistent across many galaxies.

[Q&A+] Alternative Dyson Spheres, Vera Rubin's Data, Source of Magnetars

Q: Will LSST have regular data releases?

Yes, Rubin's LSST will provide live data updates with minimal delay, along with periodic larger data releases for various astronomical events.
