What is stronger than a black hole
The most powerful supernova yet recorded (ASSASN-15lh) was 22 trillion times more explosive than a black hole will be in its final moments. It doesn't matter how small or how massive a black hole is, their closing fireworks are exactly the same. The only difference is how long it will take a black hole to explode.
What is the difference between a quasar and a black hole
Today most astronomers believe that quasars, radio galaxies and the centres of so-called active galaxies just are different views of more or less the same phenomenon: a black hole with energetic jets beaming out from two sides. When the beam is directed towards us we see the bright lighthouse of a quasar.
Why would it be impossible to survive near a black hole
Black holes sound like objects from a science fiction story. These objects are dark, dense regions in the universe, and their gravitational pull is so strong that nothing can escape them—not even light!
What are two of the three major parts of a black hole
Black holes have three "layers": the outer and inner event horizon, and the singularity. The event horizon of a black hole is the boundary around the mouth of the black hole, past which light cannot escape. Once a particle crosses the event horizon, it cannot leave. Gravity is constant across the event horizon.
What can destroy a black hole
Eventually, in theory, black holes will evaporate through Hawking radiation. But it would take much longer than the entire age of the universe for most black holes we know about to significantly evaporate.
Can a black hole destroy a galaxy
Astronomers have suspected that feedback, in the form of powerful radiation emitted by material swirling around a supermassive black hole at the center of a galaxy, can heat molecular gas in that galaxy and prevent it from collapsing to form stars. It could possibly even blow that gas out of a galaxy entirely.
Is A quasar more powerful than a supernova
A single supernova outshines an entire galaxy for a few weeks. A single quasar can outshine 10,000 galaxies for millions of years. Take that, supernovas, you chumps. Quasars are by far the most powerful engines found in the universe.
What is stronger than a quasar
GRB are more powerful than quasars, but only last a short time. GRB are form a beam of radiation. So if a GRB and a quasar are equally distant, the GRB would appear brighter.
How long is 1 minute in a black hole
Black hole news: Standing on edge of black hole would cause 700 years to pass in 1 minute.
How to destroy a black hole
Called quantum fluctuations of the vacuum. According to quantum mechanics. A given point in space-time fluctuates.
Who created dark matter
Fritz Zwicky
The term dark matter was coined in 1933 by Fritz Zwicky of the California Institute of Technology to describe the unseen matter that must dominate one feature of the universe—the Coma Galaxy Cluster.
Are we inside a black hole
We might be the product of another, older universe. Call it our mother universe. The seed this mother universe forged inside a black hole may have had its big bounce 13.8 billion years ago, and even though our universe has been rapidly expanding ever since, we could still be hidden behind a black hole's event horizon.
Can a black hole eat a galaxy
There is no way a black hole would eat an entire galaxy. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for eating the whole galaxy.
Can a black hole destroy a star
Multiple NASA telescopes recently observed a massive black hole tearing apart an unlucky star that wandered too close. Located about 250 million light-years from Earth in the center of another galaxy, it was the fifth-closest example of a black hole destroying a star ever observed.
Has a black hole ever hit Earth
Problem is, no such thing has even been detected. Now part of the trouble is that these impacts would be rare. For the smallest PBH masses, there may only be one black hole hitting the earth every million years. For the Phobos-mass black holes or larger, you may only get one in the history of the earth.
Will a black hole ever hit Earth
The possibility that a black hole could actually impact Earth may seem straight out of science fiction, but the reality is that microscopic primordial black holes could actually hit Earth. If one did, it wouldn't just impact like an asteroid, it'd pass straight through the entire Earth and exit the other side.
What is stronger a supernova or a kilonova
Kilonovae occur when two compact objects, like binary neutron stars or a neutron star and a black hole, collide. These mergers, as their name suggest, are about 1,000 times brighter than a classical nova, but not as bright as a supernova, which is 10 to 100 times brighter than a kilonova.
Can a quasar destroy a star
Quasars have at their core a “supermassive” black hole, which contains as much matter as a billion suns. A typical black hole contains as much as about 10 suns. The “supermassive” black hole sucks in and crushes any material that comes near it – whole stars and planets, Schmidt said.
Can quasars destroy galaxies
New data from NASA's Hubble Space Telescope details what may be the most powerful phenomena in the universe: the "quasar tsunami," a cosmic storm of such terrifying proportions that it can tear apart an entire galaxy.
Is A quasar Hotter Than The Sun
The quasar is 100,000 billion times brighter than the sun. Astronomers stared deep into the heart of a hungry black hole, only to discover a jet of X-rays beaming out of it that is 60,000 times hotter than the surface of the sun.
Is black hole faster or light
Going faster than the speed of light
Astronomers agreed that the black hole was spinning really fast, but obviously not as faster than the speed of light — the universal speed limit.
Can black holes break time
It implied that black holes break the fundamental time symmetry of physics, destroying information and preventing, even theoretically, the reversal of a sequence of events from the future back to the past. This has become known as the black hole information paradox.
Is dark matter the God
In this sense, at least, there is a deeply religious side to physics. In this sense, physics at its best is an adventure in spirituality. But back to dark matter. My point is not that dark matter is God, although it may well be an embodiment of God.
Who can destroy dark matter
Dark energy may destroy itself and decay. It may convert into baryonic matter or even birth a brand-new particle. Because we don't understand how it is made, we also do not know how to destroy it.
What’s beyond a black hole
Beyond the event horizon lies a truly minuscule point called a singularity, where gravity is so intense that it infinitely curves space-time itself. This is where the laws of physics, as we know them, break down, meaning all theories about what lies beyond are just speculation.
