The concept of time travel has always captured the imagination of physicists and laypersons alike. But is it really possible? Of course it is. We’re doing it right now, aren’t we? We are all traveling into the future one second at a time.
But that was not what you were thinking. Can we travel much further into the future? Absolutely.
If we could travel close to the speed of light, or in the proximity of a black hole, time would slow down enabling us to travel arbitrarily far into the future. The really interesting question is whether we can travel back into the past.
And all three of these shapes were exactly what the PHENIX scientists observed. It’s our first good peek at what the universe began forming in its very earliest moments after the Big Bang.
If you have ever looked into the ‘many world’s theory’ you know that the world we live in is quite possibly one of many. Regardless of the multiverse hypotheses, you choose to follow/look into each one is truly fascinating for a number of reasons.
Basically, most of them touch on how there are many different worlds, universes, dimensions, or whatever you would like to call them. Each one the same as our own but also different in some way. For instance, in another world, you might be living the same life as you are now but perhaps politics had gone in a different direction. Maybe all of the presidents that were elected here in the US were opposite from how they are in our world. Maybe everything is the same except for you have different colored hair? The differences between worlds could be minuscule or extreme, it all varies.
While throughout the years’ many physicists and researchers, in general, have been trying hard to prove the existence of this kind of thing, it has proven to be quite the task. That being said, the concept itself has not been disproven. Now, what this article is about is a concept many do not realize is quite prevalent in these theories. We are all connected to these other worlds or universes. Each one might be separate from our own but it has been suggested time and time again that when we experience things like deja vu or peculiar dreams we are getting a glimpse into one of these other worlds.
This is the farthest away that black hole wind has ever been known to extend.
Astronomers studying the universe’s first light — the light from the first stars, which ignited nearly 14 billion years ago, according to the European Southern Observatory (ESO) — have made an unexpected discovery.
While scouring the distant cosmos with the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile, the scientists came across a streak of thermal wind spewed from a far-flung black hole, which had traveled a staggering distance from the galaxy where it originated.
There are churning, hellish, hot-and-cold gas storms swirling around our universe’s supermassive black holes. But the scientists who discovered them would prefer you call them “fountains.”
That’s a change from “donuts,” the term researchers previously used to describe the roiling masses. But a paper published Oct. 30 in The Astrophysical Journal reveals that the donut model of the mass around black holes may have been too simplistic.
About two decades ago, researchers noticed that the monster black holes at the centers of galaxies tended to be obscured by clouds of matter — matter that wasn’t falling into the black holes but rather circulating nearby. But astronomers couldn’t get a clear look at those clouds. They were able to simulate the currents around black holes, though, as in this example published in The Astrophysical Journal Letters in 2002, and they concluded that those clouds were donut-shaped — gas falling toward the black hole, getting heated up by proximity and bouncing away, only to fall back toward it again.[What’s That?

Scientists at the University of Oxford may have solved one of the biggest questions in modern physics, with a new paper unifying dark matter and dark energy into a single phenomenon: a fluid which possesses ‘negative mass.” If you were to push a negative mass, it would accelerate towards you. This astonishing new theory may also prove right a prediction that Einstein made 100 years ago.
Our current, widely recognised model of the Universe, called LambdaCDM, tells us nothing about what dark matter and dark energy are like physically. We only know about them because of the gravitational effects they have on other, observable matter.
This new model, published today in Astronomy and Astrophysics, by Dr. Jamie Farnes from the Oxford e-Research Centre, Department of Engineering Science, offers a new explanation. Dr. Farnes says: “We now think that both dark matter and dark energy can be unified into a fluid which possesses a type of ‘negative gravity,” repelling all other material around them. Although this matter is peculiar to us, it suggests that our cosmos is symmetrical in both positive and negative qualities.”
