In all seriousness, this sounds like a job for Space Force. After the billions spent, if it can't destroy a single target with no maneuverability, what chance does it have against a modern ICBM?

I would drop Evolution for the film that started this genre 50 years ago - The Rocky Horror Picture Show. Let's all do the Time Warp again.

Except for one thing - when dark matter first formed, according to the theories I've read, there was no regular matter to form atoms because the universe was too hot. I've mostly read about in relation to the birth and development of the cosmic web but I feel the gravity that drew the dark...

I would go further and suggest that all early black holes, massive and supermassive, were created in the early universe before population 3 stars and are composed entirely of dark matter. Population 3 stars came and went later and seeded the galaxies that formed around the preexisting black holes.

Question - Just as the gravity of a normal star can affect the light from a star it passes in front of, would this also be true of a boson star?

In general, manned missions will survive in some form and I suspect that the moon will be the target due to China. My concern is science missions. The Europa Clipper and DAVINCI will probably be cancelled entirely along with smaller deep space missions. I doubt we'll see any new non-human...

While our universe is too big to discount the possibility of an intermediate sized black hole forming somewhere, it will be just a curiosity. It is time to discard the theory that the formation of super-massive, much less ultra-massive, black holes have anything to do with stellar or...

One problem that is not mentioned is parking orbits, where satellites that as decommissioned are relocated to. All satellites should be required to be designed for earth reentry and the parking orbit intact satellites should be prioritized for removal.

To me, two things stand out. Desire and Perspective. Desire - A galactic spanning civilization has to want to be galactic spanning. The only civilization we know of was built on conquest and colonialism. Surely other, more peaceful, civilizations arise in the cosmos who are content to stay in...

Given the status of the Russian space program, I would guess that somebody used a paint rattle can to cover up a scratch.

Does Deimos's orbit allow for a much smaller eclipse as well?

Out of curiosity, do any of the last parsec simulations include the possible influence of dark energy or dark matter?

Keep in mind that it would have been subjected to thousands or millions of years of weathering by Martian dust.

Interesting, if true, but ISTM that the Occam's Razor explanation is that it's an Earth meteorite.
