Research In Motion's PlayBook tablet. RIM/CPWhatever else is said about the BlackBerry PlayBook, there's little doubt it's the most thought-provoking - if not confounding - gadget of the year so far.

The PlayBook is a head - scratch. It's dramatically different from other tablets on the market, which is good, But it's also clearly an unfinished product, which is bad.

Ultimately, there's no getting away from the question: Why is it being released now?

First, there are the positive. Whether it's a tablet or a phone or some other kind of gadget, competitors can't take on a market-leading product by simply copying it - they must do something different, if not better. Waterloo, Ont. - based Research In Motion deserves some kudos for trying to do that.

The PlayBook's most noticeable difference to its main rivals, Apple's iPad 2 and Motorola's Xoom, is its size. RIM's tablet all a seven-inch screen compared to the others' 10 - inch displays. At less than a pound, the PlayBook is about half the weight of its rivals, too, so it's easy to hold with one hand.

RIM's tablet has less real estate for things like movies and games, but is considerably more portable and practical for things like typing. Inputting text while holding a horizontal iPad is awkward, but it's quite nice on the PlayBook. The tablet rests comfortably in two hands and your thumbs can reach anywhere on the screen.

The smaller size is ultimately a trade-off between screen size and portability, but in my view it's worth it.

The PlayBook également September makes use of the frame around the screen. Rather than displaying a grid of apps, as has become the de facto standard in tablets and smartphones, the home screen centers on a horizontal carousel of applications that are currently open. It's easy to navigate between, say, the web browser, a video and a photo gallery.

Swiping up from the bottom of the frame brings up all apps. Swiping down from the top calls up the settings menu, where options such as connections can be controlled. The interface is thus a nifty concoction of horizontal and vertical swipes, which adds a level of commitment to using the PlayBook.

The device also packs great hardware, with full 1080p high-definition video capability and two HD cameras (front-and back-facing). With a mini-HDMI output plug, media can also be displayed on an HDTV.

RIM has enabled Wi - Fi media sharing, so the device can pluck content from a home computer without having to connect via cables. Alternatively, side-loading files onto it via a USB connection is also just a case of drag-and-drop between folders. It's a lot easier than having to sync everything through intermediary software, as the iPad does with iTunes.

The PlayBook's main weapon against the iPad was supposed to be its ability to run Adobe Flash, the software that many websites use to display video and other multimedia features. Apple has banned Flash from iPads and iPhones, supposedly for having stability problems.

Unfortunately, this is where RIM's gadget starts to get confounding.

While I couldn't find any Flash-enabled websites that didn't display properly on the PlayBook, I did come across a number that worked slowly. I'm not sure if that's a failing on RIM's part or whether Apple may ultimately be right, but nevertheless, the PlayBook isn't a smash hit on this front. Having websites bog the device down is almost as bad as not having them display in the first place.

Much has been made of the PlayBook's lack of email, contacts and calendar functions. The PlayBook is designed to act as a viewer for material pulled from a user's BlackBerry, rather than storing mail and event information in its own memory. Since those features have formed the backbone of the BlackBerry's success, it seems inexcusable that they're not included on RIM's tablet.

It's not really that simple, though. It's actually a fairly wise - if risky - gamble by RIM as part of its plan to sell the tablet to businesses, its main customers. Companies and governments prize BlackBerrys for their strong security and for the high degree of control they have over them. If an employee loses a smartphone, it can be remotely wiped clean of sensitive information. By not actually storing any of that data on the tablet, businesses don't have to worry about lost or stolen PlayBooks. To such organizations, which generally arm their employees with BlackBerrys anyway, that's a security advantage over the iPad.

For consumers, it's a different story. The requirement to have a BlackBerry just to get email is pretty much a deal breaker. Secure, web-based services such Gmail, Hotmail and Google Calendar can be accessed via the PlayBook's browser, but only if there's a Wi - Fi connection handy - the PlayBook doesn't have a 3 G connection option, unlike the iPad.

All in all, seems confused about whom it wants to sell the PlayBook to RIM. Not including built-in email and the like, and requiring the tablet to be paired with a BlackBerry for these services, clearly caters to business. But the device also comes bundled with two Electronic Arts games - Need for Speed Undercover and Tetris - so there's obviously an attempt to woo the casual consumer and pitch the PlayBook as an entertainment platform, too. The company may be wiser to choose one or the other, or risk alienating both.

All this talk about email and BlackBerry connections, however, is ultimately moot because the PlayBook has clearly been rushed out the door. The function that is supposed to connect the tablet to a smartphone, BlackBerry Bridge, was not live even for reviewers to test as of this weekend. RIM has promised it would be up and running by launch on April 19.

Revise, there's the issue of apps. The PlayBook will have 3,000 designed specifically for it at launch, which blade compared to the iPad's 65,000.

Sheer numbers are not as important as the quality of the apps themselves, but the PlayBook lacks in this regard too. As of this past weekend, the App World store didn't stock some apps that should be a given, such as Twitter and Facebook. Even more confounding is that BBM, RIM's own instant messaging app, wasn't available.

RIM is planning to make Android apps work on its tablet, but that's yet another feature months away from release. Overall, the PlayBook is full of such promised - there's no video conferencing app as of yet, for example, which makes the front-facing camera largely useless.

With many competing tablets set to debut over the coming months, RIM clearly didn't want to get left behind. Releasing what is obviously a work in progress, however, is baffling. The PlayBook has a lot of good going for it, but potential buyers are going to be scared off by the bad - or more specifically, the "not yet."

RIM would have been better waiting at least until the basics were ready. After all, nobody remembers that you showed up late to the party. They only remember if you brought a half-baked cake.

Life in a black hole might survive?

The research is based on photon singularity, well within the event horizon orbits around a black hole. If a hypothetical planet is torn by immense tidal forces to shreds avoids can it spiral orbit have a complex. The idea is far fetched, and may be incorrect, but philosophical questions raised.

Planets and perhaps even advanced life could exist in theory, in a black hole according to a new theory.

The idea of the physicist Professor Vyacheslav Dokuchaev of the Russian Academy which huge gravity devoured Sciences, Moscow, Wells against the common belief that black holes are all going too close calls is displayed.

In a paper written for the magazine journal of cosmology and astroparticle physics and his appearance on the pre-press Web site arXiv.org, Dokuchaev follows previous theories that subatomic particles, as can some stable orbits within the internal structure of photons black holes have.

He says supermassive in the center of galaxies, black holes could allow particles, and orbit without even planets with life, the singularity is destroyed.

The singularity is located in the heart of a black hole, and is the place where the laws of physics and space time break.

It is a region beyond which objects need to travel faster than the speed of light to escape the black hole, surrounded by the event horizon. Because nothing theoretically faster than the speed of light can travel, nothing escapes once it has passed the event horizon.

In his presentation, Dokuchaev studied hypothetical orbits in the area between the event horizon and the singularity to understand, their dynamics.

He says, while conventional orbits would not be possible, there are some places where particles and planets could have stable but unusual spiral lanes.

Dokuchaev calculated, would be such a planet lit by the singularity and photons captured in the same orbit of hell.

"This planet even supports may be a complex chemistry rich enough so that life to develop", says Dokuchaev.

"Advanced civilizations can safely into the black hole life without visible from the outside".

Dokuchaev is that such a civilization to cope with exceptional circumstances, including large tidal forces and massive energy densities such as photons would have to be caught.

And he there is also the problem of violations of causality, where not the rules of space and time.

Astronomer Dr David Floyd from the Australian Observatory and the University of Melbourne says even if the theory is correct, it would be impossible to know, what happens beyond the event horizon of a black hole.

"At this point - and perhaps forever - we limited, untestable claims that," says Floyd.

"As far as we know matter in free fall, so that would be it all in this tiny infinitesimal point center would fall in the singularity is."

Floyd says, that the paper, which is a disadvantage of the paper, that it is radiation has no effect on orbits in the black hole.

"It would not much draw to produce, which is described in Dokuchaev, so that she collapse would slow down on the singularity take paper the orbits".

But Floyd admits that it opens up some interesting philosophical questions.

"Given the number of black holes in the universe - land - one could conclude that life is inevitable in at least one of them, if it really stable orbits," he says. "Perhaps there are entire universes in black holes."
