@ilza: I'll tear up my engineering degree and tell Lawrence Krauss he's a quack. Thank you for setting us straight.

"does rocket just outside EH see same thing as Earth observer sees 1 month later"

The Earth will appear blueshifted (higher frequency) to the rocket. The laser coming from from the rocket will...

"So, in your educated opinion, the situation of “a moving black hole” differs from an object falling to a stationary black hole? Yeah, right!"

At time T = 0, black + object at distance X with no...

Consider objects approaching the cosmic horizon (which is identical to objects approaching any horizon):

"Objects therefore appear exponentially redshifted as they approach the horizon. Finally,...

<" THERE IS NO NOTION OF A MOVING OBJECT! Speed is a RELATIVE notion">

Your statement is an exercise in gibberish as are your other statements. Speed is the magnitude of relative motion. To say...

An expanding black hole is no different from a moving black hole: it simply changes how fast an infalling object approaches the event horizon. If a lot of matter is falling into a black hole at...

The math says that as an object approaches the event horizon, the observed passage of time to an outside observer approaches zero. It will never reach zero but the distance will decrease...

It will take forever for you to "see" the matter cross the event horizon. From our point of view, rather than a "frozen image", the infalling matter becomes more and more red shifted and dimmer. ...

Mars is fundamentally uninhabitable. We could fill Earth's oceans with garbage until we can walk on it, then detonate every nuclear warhead on Earth, then get hit with a dino-killer asteroid, and...

There are fields of photography producing images for business purposes rather than art: website graphics, advertising, online/offline catalogs, product manuals, etc.

In that case It's important...

I don't think Amazon cares. Amazon Basics and Peak Design products are aimed at different customers.

The average Amazon Basics customer is judging whether to buy the $10 no-name bargain sling...

The price keeps rising for the Amazon bag (was $27 a few minutes ago, now $30 as I write this), which according to the Amazon algorithm means its selling well (possibly thanks to this article). It...

It says "cruelty-free, environmental-friendly, and non-toxic synthetic leather". So its not real leather (veg or chrome tanned) and likely not a petroleum-based synthetic leather. It could be...

I would laugh if one person enters. The OP will be out $65....

@grahamho, "This criticism of a woman photographer"

You're the only one bringing gender into the discussion.

"You tell me why some readers of this article are criticising the technique "

Expense/profit has nothing to do with fraud. Most "contests" that require an entry fee (eg, lottery tickets, casinos) are bad value to the contestants and result in high profits for the operator. ...

I picked up on that as well. But as she said, the lens is much larger than what she normally uses (85mm?). So I suspect she's simply adapting her normal technique to an atypical situation. If you...

Now we only need a Verneer painting of DPR's studio test scene so we can add him to the comparison tool. That way I can compare him against my 5Div. IMHO, Canon has the edge in sharpness.
