A Harvard physicist has shown that wormholes can exist: tunnels in curved space-time, connecting two distant places, through which travel is possible.

But don’t pack your bags for a trip to other side of the galaxy yet; although it’s theoretically possible, it’s not useful for humans to travel through, said the author of the study, Daniel Jafferis, from Harvard University, written in collaboration with Ping Gao, also from Harvard and Aron Wall from Stanford University.

“It takes longer to get through these wormholes than to go directly, so they are not very useful for space travel,” Jafferis said. He will present his findings at the 2019 American Physical Society April Meeting in Denver.

An inevitable comment is usually something along the lines of women don’t need this kind of help because “insert foolish reason here.” The announcement of the black hole image shows just why this kind of action is needed.

The soon-to-be iconic picture of Katie Bouman reacting to the first image coming through was posted. Suddenly, the Internet trolls in defense of “male scientist” broke upon the scene, The goal to denigrate Bouman’s work on the project and turn the real “hero” of the discovery to another male scientists.

WASHINGTON (AP) — Scientists on Wednesday revealed the first image ever made of a black hole, depicting a fiery ring of gravity-twisted light swirling around the edge of the abyss.

The picture, assembled from data gathered by eight radio telescopes around the world, shows the hot, shadowy lip of a supermassive black hole, one of the light-sucking monsters of the universe theorized by Einstein more than a century ago and confirmed by observations for decades. It is along this edge that light bends around itself in a cosmic funhouse effect.

“We have seen what we thought was unseeable. We have seen and taken a picture of a black hole,” Sheperd Doeleman of Harvard, leader of a team of about 200 scientists from 20 countries, announced as the colorized orange-and-black picture was unveiled.

In April 2017, scientists used a global network of telescopes to see and capture the first-ever picture of a black hole, according to an announcement by researchers at the National Science Foundation Wednesday morning. They captured an image of the supermassive black hole and its shadow at the center of a galaxy known as M87.

This is the first direct visual evidence that black holes exist, the researchers said. In the image, a central dark region is encapsulated by a ring of light that looks brighter on one side.

The massive galaxy, called Messier 87 or M87, is near the Virgo galaxy cluster 55 million light-years from Earth. The supermassive black hole has a mass that is 6.5 billion times that of our sun.

On 10 April 2019 at 15:00 CEST (Brussels time) the European Commission will present a ground-breaking discovery by Event Horizon Telescope — an international scientific collaboration aiming to capture the first image of a black hole by creating a virtual Earth-sized telescope. EU-funded researchers play a key role in the project.

Six press conferences around the world will take place simultaneously In Europe, Commissioner Moedas and lead scientists funded by the European Research Council will hold a press conference in Brussels to unveil the discovery.

The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow.

This breakthrough was announced today in a series of six papers published in a special issue of The Astrophysical Journal Letters. The image reveals the black hole at the centre of Messier 87 [1], a massive galaxy in the nearby Virgo galaxy cluster. This black hole resides 55 million light-years from Earth and has a mass 6.5 billion times that of the Sun [2].

The EHT links telescopes around the globe to form an unprecedented Earth-sized virtual telescope [3]. The EHT offers scientists a new way to study the most extreme objects in the Universe predicted by Einstein’s general relativity during the centenary year of the historic experiment that first confirmed the theory [4].

The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun
