Comment on Big Black Holes by NeilEnnis

Thanks for the reply, Nick. You’re right. My approach is too simplistic because I don’t understand it as well as I should. Was I correct in thinking that the force of gravitational attraction just outside the event horizon could be close to 1g if the black hole was large enough? If so, does this make any difference? I.e. could a hypothetical observer safely approach the event horizon without having to deal with the normal issues we read about such as tidal forces, time dialation, increased mass, extremely curved space, etc?

The simple answer to everything here is that your approach is too simplistic. It is often useful to talk about black holes in terms of escape velocity, but ultimately wrong, because it leads to the question, “What if I accelerate?”. The answer is that when you do the full GR, you find that the causal structure of space-time forbids exiting the event horizon, regardless of your trajectory. Inside the horizon, the direction of “time” switches with the direction of “space”, meaning that all future-directed trajectories lead further inside the black hole.

This works perfectly. Thanks. I understand previous versions of windows also had trouble updating under the same settings.

Comment on Slideshow from RSS for WordPress by Dushyant Ahuja

Hi,

I’m trying to use the google feed slideshow (http://www.google.com/uds/solutions/slideshow/reference.html) and most of the time it works perfectly, however sometimes in Google Chrome the images get offset by 90 pixels – so the page displays only 1/4th of the image. If you know how this can be corrected, please let me know.

Regards,
Dushyant

Comment on Flickr RSS Feeds. Too big, too small by NeilEnnis

Greg, it can be done in the same way for Picasa. Look at the difference between the URL for the thumbnail and the main image, and adjust the php code to change one to another. The thumbnail will have a string like “s288″ towards the end. The main image will have something like “s512″ or “s1024″. You’ve just got to replace one with the other. Let me know if you need a hand.
