Trillions of Rogue Planets Hidden In Our Galaxy With One Very Close

I wouldn't necessarily watch the video, but I find it interesting that there are all these Rogue Planets moving around the galaxy.  It would be very unlikely, but if one were to pass through the orbital plane of our solar system, then it could alter the orbit of one or more planets.  There is a remote chance that this has happened before.  Sometimes they talk about how planets get ejected from solar systems by massive objects.

Fortunately, the galaxy is very big, thus reducing the chance of having an encounter like this.

What's the truth about antigravity?

https://www.youtube.com/watch?v=_SGnOeGZUAU

I had a manager who believed that since magnetism is a dipole, that we should also have positive and negative gravity.  The problem with this idea is that it is likely a bad analogy.  I have seen videos stating that gravity is not a force, but a by-product of moving through curved spacetime.  (I am still skeptical of the "spacetime" concept, thinking of it only as a useful and accurate model.)

Anti-matter is simply matter that has an opposite charge.  There is no reason to think that it would be affected in a different way by gravity.  If it were, I think that we would have to rewrite the laws of physics.

Dark Matter's Last Stand - Scientific American

Scientists are fond of saying negative results are just as important as positive results, but after several decades of not finding something, researchers can be forgiven for feeling impatient. Back in the 1990s, experiments began trying to detect the particles that make up dark matter, the ubiquitous yet untouchable invisible material that apparently fills the cosmos. Since then, physicists have found more and more evidence that dark matter is real but not a single sign of the stuff itself.

AMAZING INVENTIONS THAT ARE NEXT LEVEL!

Not sure how many of these are useful.   Some inventions can be cool but not cost-effective.  This reminds me of looking at magazines in the 1970s where they predicted that we would have nuclear-powered cars by the year 2000.
