Updated: Black Friday Deals UK: how you can pick up mega deals on tech this month

We've added the first black friday retail links to the bottom of this page so you can mentally prepare yourself for the Deal Nirvana ahead!

In the US and Canada, Black Friday needs no introduction: it's a time for big sales, crazy prices and CCTV footage showing shoppers knocking lumps out of each other.

But it's becoming a huge deal in the UK now as well, with some of the biggest retailers like Amazon slashing their prices for one day only.

And the best news? TechRadar will be busy finding all the best deals on phones, headphones, speakers, cameras, games and more, and posting them here so you can find them more easily.

So what is Black Friday - and while we're at it, how is it connected to Cyber Monday?

Black Friday is the first Friday after Thanksgiving, and it represents a perfect storm for retailers: many people in the US have the day off, and as a result it's been the busiest shopping day of the year for nearly a decade.

To make things even busier, many retailers now offer some of their best sale bargains on Black Friday. Even Apple joins in.

That depends on when you're reading this. If it's 2014, Black Friday is Friday 28 November. If it's 2015, it's Friday 27 November. And if it's 2013, you've been asleep for a year. The things you've missed!

Take your pick: some say it's the day that retailers' profits finally move into the black, although Wikipedia reckons that the true origin of the term comes from Philadelphia where it referred to the disruptive pedestrian and vehicle traffic that occurred during the holiday.

Yes it is. Every year there are reports of fisticuffs as bargain-crazed shoppers beat each other up, partly because of the practice of using "doorbusters" - amazing and excruciatingly limited deals to attract as many customers as possible. US-based retailers such as Amazon are now keen to make it a tradition here in the UK.

Cyber Monday is the Monday immediately after Black Friday, and it was invented in 2005 in an attempt to create an online equivalent of Black Friday. What this has resulted in now, is an entire 4-day weekend of hot deals both in store and online.

No one likes a tech bargain more than TechRadar! And we don't want to keep them all to ourselves.

So we'll be beavering away tirelessly all weekend to constantly bring you the hottest deals as they go live online. You'll need to keep your wits about you though, because many deals only last for an hour or until stocks run out. So you need to be quick off the mark - and we'll be on hand to make it as easy for you as possible.

Tune in to TechRadar on November 28th, 29th, 30th and December 1st to get at the hot deals first!

Don't you know that patience is a virtue?! It's not Black Friday yet, but okay - we've put together a list of retailer's Black Friday pages so that you can take a look now and see what it's all about. We'll be adding more soon, and of course, this page on TechRadar will be the place to be with a curated list of all the best deals!

Are we all here because of a black hole?

When we think of black holes, many of us tend to think of them as massive death machines that suck anything and everything out of the sky around them, never to be seen again.

Not even light can escape the gravitational pull of a black hole, making them impossible to observe directly. But could these collapsed stars actually create things? Could the supermassive black hole at the center of the Milky Way be directly responsible for creating many of the stars that light up the night sky? New research suggests that it's not only possible, but likely.

Supermassive black holes are normally found at the center of galaxies, with plenty of stars, planets, and other celestial bodies nearby. But recently, astronomers came across one that breaks that rule, sitting out there by itself without anything else surrounding it. And it's incredibly active, sucking up gas and emitting a huge jet of materials that crash into dust and gas in a nearby galaxy to form new stars.

That galaxy is building new stars at an accelerated rate, suggesting that the black hole is likely playing a part in the star creation process.

This isn't the first time it's been suggested that supermassive black holes play a role in creating stars. A 2009 study in the journal Astronomy & Astrophysics posited that quasars (which are believed to contain black holes) played a role in star formation and a 2012 study in the Monthly Notices of the Royal Astronomical Society examined the role black holes played in creating new stars.

If these theories are true, the supermassive black holes at the center of the Milky Way could be responsible for some or all of the stars we see in the sky, including our sun.
