Scientists aim to open the first picture of a black hole



The world, apparently, suddenly sees the first picture of a black hole.

On Wednesday, spectators around the world will hold "six big conferences of the papers" at the same time as the first results of Telescope (EHT) Event, which was designed specifically for the publish that reason.

It's a long time.

Of all the forces or objects in the world we don't see – including dark and dark power – no-one is bothered by the philosophy of people as big as the hidden branches dressed in swallowing stars like as much dust.

Astronomers began to consider these "dark stars" in the 1700s, and since then direct evidence has gathered slowly.

"Over 50 years ago, scientists saw something very clear at the heart of our galaxy," said Paul McNamara, the European Space Agency's astrophysicist, and an expert on black holes, AFP.

"The tug about the window is strong enough to star all around it quickly – as fast as 20 years."

To do so, our solar system takes around 230 million years to build a circle at the center of milk.

Finally, astronauts thought that these bright spots were indeed the "black holes" – a term inserted by the American scientist John Archibald Wheeler in the mid-1960s – surrounded by a downfing of white-gray and gray plasma.

At the inside of these discs, things are going dark.

"The event event" is not a physical barrier – out-of-back "- you can't stand on it," McNamara explained. "If you're inside you can't escape as you would need infinite energy. And if you're on the other side, you can – in principle.

At its center, a hole in the black hole will be inserted into one single-dimensional point.

The distance between the singularity and the direction of the event is the radius, or half the width, of a black hole.

The EHT that collected the data for the first image is ever the same as any ever created.

"Instead of building a large telescope – which might fall under its own pressure – we put together several surveys as if they were part of a large mirror," said Michael Bremer, a geologist at the Institute for Cycling Radio Millimetric Biography. the Grenoble, AFP.

In April 2017, eight world-wide radio telescopes were received – in Hawaii, Arizona, Spain, Mexico, Chile, and the South Pole – training on two black holes in different corners in the city. world to collect data.

Searches for this week are likely to go in in one or other.

Makers from selecting Sagittarius A *, the black hole in the middle of our earring, first caught the eye of astronomers.

In A * Saga, four million times higher than sunshine, means that the black hole represents about 44 million kilometers across.

That may be a big target, but for the telescope that created it on the ground about 26,000 light years (or 245 billion kilometers) away, it's about trying to take a photo of a golf member on the Moon.

The other candidate is a monster black monster – 1,500 times larger than that of Sag A * – in a terrific ram called M87.

It is also further away from Earth, but the speed and speed of an extent can be as easy or difficult to identify.

One reason is that this dark horse is the only thing that was published next week and light-hearted inside Milk Way.

"We sit in the lawn of our stars – you have to look through the stars and the dust to get to the center," said McNamara.

The data collected by the series of long-term telescope had been collected and taken together.

"The algorithms that we put together will fill the data gaps that we want to rebuild a picture of black holes," said the team on their website.

The archaeologists are not involved in the project, including McNamara, keenly – perhaps emotionally – waiting to see if the results challenge Einstein's theory of universal friendship, which has not has been tested on this scale.

Looking forward in 2015, this allowed scientists in a Nobel Prize to use wave researchers on the ground to monitor two black holes colliding. T .

As they merged, this collapses with the gaps in the timescale by creating a unique, invisible signature.

"Einstein's theory of general relativity states that this is the case," said McNamara.

But these were little black holes – just 60 times the sun – compared to any of those controlled by the EHT.

"Perhaps those are millions of times more different – we don't know yet."
