"Supermassive black holes are around 100,000 solar masses. " Actually they appear to start at that size by definition: https://en.wikipedia.org/wiki/Super-massive_black_hole And the biggest appears to be in the Quasar TON 618, at ca. 66 billion solar masses...

This was quoted from wiki* : "Given that Toutatis makes many close approaches to Earth, such as in 1992, 1996, 2000, 2004, 2008, 2012, and 2016, it is listed as a potentially hazardous object.[12] With an uncertainty parameter of 0,[3] the orbit of Toutatis is very well determined for the next...

There is some debate about the actual size and even number of major impactors that might have given rise to the moon. So your point is well taken regarding the differentiation aspect. It does appear that many people who have studied the longevity of our core buy into the "added alloy school"...

The worst case scenario cannot be modeled or predicted. That would be a long-period comet (LPC) that is first seen a few months before impact, and the knowledge of our trouble would become apparent only after significant data had been obtained on its path and interception confirmed. It is...

There can be no other answer. You can even bring in all the multiverses and extra dimensions because in the end, they are all one universe. That is why they call it that!

This is of course a scam, like winning a free cruise you have heard from all those robocalls. Only this one is real in the sense you can go there with a "thought trek". And no credit cards are needed!! It is completely free! (Pets, alien or otherwise, are not allowed.) The trip only requires...

Especially since with some it is hard to understand one of the blighters, even when they claim to be talking in English.

Some might use your question as the answer. It all boils down to the "unknowable" aspect, which has no meaning for many. This is all purely "philosophical" in nature and does not intrude on the realm of fact-based science. Science discovers things and make them work without consideration of...

For those of you unfamiliar with the term, "todswaddle" is a highly technical, scientific description of notions, concepts or theories that have no foundation whatsoever in reality. That does not mean they do not exist. It simply means they do not exist in reality. Different dimensions and...

Well there certainly aren't many presumptions made in these calculations. :) They say he went down "the rabbit hole", and in this case appears to be truly reporting from "Wonderland" rather than a reality-based position. It sure makes some people wonder about the "science" of such...

You are not completely alone in considering this mechanism. Curiously it never crossed my path doing the research before posting this thread, so one might consider it an outlier concept (but just my cup of tea!). So there clearly is some support for tidal forces, and it certainly seems...

One might suspect he is referring to using the same stages and props for filming some new Star Trek movie.

Of course you know this is all for fun! And your posts offer some of the best amusement on this site. All the more reason to get you to comment on just about anything! :)

Just a few pesky questions - (you can ignore them if you please) - Did you have any brilliant ideas about some "better life form" that does not currently exist on the planet?! One or more examples from the past, perhaps. And what exactly are these "redundant life forms", and why do they need...

The convection of a conducting liquid alloy of iron and nickel inside the Earth results in the formation of its magnetic field. This field protects our atmosphere from the harsh solar radiation which would otherwise strip the atmosphere and water from the surface, leaving a barren planet like...
