A galaxy swirls around a black hole

At the center of our galaxy, gasses, stars, and nebulae swirl around a supermassive black hole, Sagittarius A.1   

Stephen Hawking explained the proportion of matter in a black hole to the matter we know.

“…the black hole would have the mass of  a mountain compressed into less than a million millionth of an inch, the size of the nucleus of an atom!” 2

For the Earth to make a black hole, it would have to be squeezed to the size of a cranberry.

In A Brief History of Time, by Stephen Hawking (New York, Bantam Books 1988) and The Black Hole War by Leonard Susskind (New York:  Hachette, 2008), two famous physicists present differing theories of what happens to matter inside a black hole.  They consider what happens to matter sucked into a black hole.  Does it disappear?

No one disputes that black holes absorb matter.   Matter is anything that has a volume and mass.  Everything we see is matter.   Matter takes five forms – plasma, gas, liquid, solid, and Bose-Einstein condensate, the coldest form of matter. 

We see light.  Light travels in waves.  Light is also matter.   Photons are packets of light that travel in waves. 

Black objects absorb light.    The capacity to absorb light produces blackness.   We can only see a black object if some photons reflect off the object.   

Nothing can escape the horizon of a black hole.   In contrast to other black objects, black holes absorb all photons.   That no light comes out of the horizon, makes the area inside the horizon black.  In space we see a huge gaping hole.  We can see only the horizon of a black hole.  Nothing inside a black hole can ever communicate with anything outside of it.  Of what is inside a black hole, physicists can only theorize.


At the center of the horizon lies the              singularity of a black hole.    http://www.wall.org/~aron/horizon.htm

Evaporation and obliteration theory

Cambridge’s professor Stephen Hawking theorized that a black hole destroys all matter that passes the horizon.  Hawking said:

“When a black hole evaporates, the trapped bits of information disappear from our universe.  Information isn’t scrambled. It is irreversibly, and eternally, obliterated.”4

Theoretical physicists Stephen Hawking and Bill Unruh proved that black holes, just like any other pieces of matter, have a temperature.  If black holes have a temperature, then black holes radiate heat.   Hawking and Unruh called it “black body radiation.”  Hawking and Unruh reasoned that if black holes have a temperature, then black holes eventually evaporate. 

A black hole emits “Hawking radiation.”  At the surface of the event horizon a black hole creates antiparticles.  An antiparticle is counterpart of a particle.  The antiparticle of a quark an antiquark.  When a quark and an antiquark combine, they create a hadron.  The antiparticle counterpart of small particles make up the antiparticle counterparts of large particles.  For example, a neutron is made up of quarks.   Antiquarks make up antineutrons.  The destruction of a particle leaves a neutral particle and an antiparticle.  For example, the destruction of a proton leaves a neutron and a positron.

Antiparticles can also make up “anti-elements”.  For example, a positron, the opposite of an electron, and a proton make up the anti-hydrogen atom.  The anti-hydrogen atom has the same properties as a normal hydrogen atom.5

Hawking radiation consists of particles, like light.  Unlike light, however, Hawking radiation can escape a black hole.  So how does Hawking radiation escape a black hole?      At the event horizon, virtual pairs of particles separate.

Virtual pairs of particles comprise a particle and its antiparticle.  At the event horizon, one-half of a virtual pair of particles is inside the event horizon, while the other half is outside the event horizon.  The particle inside the horizon will be lost to the particle on the outside of the event horizon.  On the inside of the horizon, the singularity sucks in half of the virtual pair.   The half on the outside of the horizon escapes the black hole’s pull.  This decreases the mass of the black hole, causing the black hole to “evaporate”.6


“Soft hairs” form a halo around a black hole.                          http://phys.org/news/2016-06-hawking-team-soft-hair-theory.html

As a black hole evaporates, it grows hotter and smaller.  After a black hole reaches high temperatures, the black hole begins to release particles of high energy.  As the black hole gradually grows hotter and smaller, it continues to evaporate.  It grows smaller.  As it grows smaller, it grows hotter.   Physicists know almost nothing about black holes once black holes reach their last burst of evaporation. 

The Hawking theory that black holes evaporate contradicts Antoine Lavoisier’s Law of the Conservation of Mass.   In 1785, Lavoisier, in his Law of the Conservation of Mass, stated that matter cannot be created or destroyed.  

Lavoisier conducted many experiments, in closed vessels, in which the weight remained constant, within experimental error.  He produced reactions of tin or lead with oxygen.  He analyzed mercury calx (HgO).  With large burning lenses he focused the sun’s rays to reach high temperatures to produce chemical reactions.  With a large lens Lavoisier burned a diamond and show that it produced only CO2.

Black holes differ from other objects in space.  Black holes have an extremely strong gravitational pull.  Nevertheless, black holes should not contradict the Law of the Conservation of Mass.

Pocket universe theory

Particle physicist Leonard Susskind teaches at Stanford.  He considered but rejects a theory that inside the black hole, a piece of space breaks off and forms a universe, isolated from our perception of spacetime. 

One of the most trusted principles of physics states that information is never lost. 7    According to the pocket universe theory, information that falls into a black hole goes into a baby universe. According to the pocket universe theory, a black hole does not obliterate information.   A black hole stores the information in the pocket universe.    This theory solves the problem with Hawking’s theory, that information cannot be created or destroyed.  If a black hole evaporated, then the information in the pocket universe would become completely unobservable. 

The pocket universe theory fails because it requires a change of energy.   To create a pocket universe would require a change of energy.   A quantum fluctuation is a temporary change in the amount of energy in a point in space.   Physicists Leonard Susskind, Thomas Banks, and Michael Peskin all agree that quantum fluctuations would transform into thermal fluctuations, changes in thermal energy.  Thermal fluctuations would almost instantaneously heat the universe to impossibly high temperatures. 


The pocket universe theory suffers a second problem.  The only way information could enter a pocket universe would be through a wormhole.  A wormhole is a theoretical passageway through space.  For example, the Einstein-Rosen Bridge is a passageway from one universe to the other through a singularity.   The singularity acts as a wormhole. John Archibald Wheeler, of John Hopkins University showed, by mathematics, that wormholes would open and closein so a short amount of time that nothing could pass through.   Susskind cites Wheeler’s wormhole as evidence that wormholes creating miniature universes would not be possible.

Information Vault Theory

Some speculate that black holes stop evaporating once they reach the Planck Mass.   The Planck mass is the combined mass of the number of particles in a Planck unit.  A Planck unit is the maximum allowed mass to contain one elementary charge.   The Planck mass is about 0.0217651 milligrams.   Physicists believe that once a black hole reaches this size, it stops evaporating.  It becomes an infinitely small information vault, containing all the information it absorbed.  This theory conforms to the Law of Conservation of Matter more than Hawking’s theory.  By the information vault theory, information is not destroyed. 

Susskind disagrees with the information vault theory.  He states that a particle containing potentially infinite amounts of information would have infinite entropy. The Second Law of Thermodynamics states that entropy constantly increases.   Entropy is decay into disorder.  Water eroding a rock creates entropy.  An ice cube melting causes entropy.  Susskind defines entropy as:

“Entropy is a measure of the number of arrangements that conform to some specific recognizable criterion.”8

 According to the First Law of Thermodynamics, heat balances itself, by flowing into cold objects.  Heat raises the temperature of cold objects and lowers the temperature of hot objects until a system has a uniform temperature.  Infinitely entropic particles would cause a thermodynamic disaster. The infinite entropy caused by the information vaults would burn up the universe.

The bathtub option


                 Entropy                  http://www.michelecoscia.com/?p=1041

Susskind compares a black hole to a bathtub.  Susskind analogizes matter entering a black hole to drops of ink spilling into a bathtub of water.   Before an ink drop falls into the water, the ink drops are sharply defined.  One can easily differentiate between the ink and the water.  As the ink falls into the water, the ink drops dissolves.  The difference between ink and water blurs.  The water becomes cloudy.  Soon all that remains is a uniform tub of slightly gray water. 

If the inky water evaporates, the molecules of ink and water continue to exist.  They enter the air.  They scatter and separate from each other.  Susskind’s “bathtub option” edits Stephen Hawking’s theory to conform to the Law of Conservation of Matter. 


Both Hawking and Susskind believe that, at the center of a black hole, the singularity, along with all the other matter inside the black hole, eventually evaporates.   Hawking theorized that a black hole destroys and obliterates all matter which enters the horizon.   Susskind’s bathtub option predicts that the matter is scattered.

Roberto Devereux

Eugene Toth, Society, Uncategorized

by Eugene Toth

For the New York Metropolitan Opera’s March 24, 2016 gala opening of “Roberto Devereux,” the eyes of opera enthusiasts sparkled.  Not only was the performance a new production.   For the first time ever, on the 413th anniversary of Queen Elizabeth I’s death, the Met staged Gaetano Donizetti’s “Roberto Devereux”

Donizetti set several operas in Britain. After Anna Bolena and Maria Stuarda Roberto Devereux was Donizetti’s third opera about British Queens.  “Roberto Devereux,” depicts the golden age of Elizabeth’s reign and the Tudor era, when poetry, music and theater flowered.

In 1599, Roberto Devereux, a former lover of Elizabeth I, returned from an unsuccessful war in Ireland, to England.   The opera tells why Elizabeth I executed him for treason.

With historical detail, exquisite costumes invoked the splendor of the Elizabethan era.  In

his first appearance, Devereux wore a black overcoat with silver lining over black plate armor, based upon a 1590 Portrait by William Segar of  Roberto Devereux, Earl of Essex.

In the Metropolitan Opera’s new production, the stage wore no curtains.  Between two balconies, a wall approached and receded from the audience.  In different scenes the wall represented a palace of Elizabeth I, the Palace of the Duke of Nottingham, and the Tower of London.  At the sides, in two galleries, chorus members acted as an audience and witnesses focusing attention upon the four soloists – soprano Elizabeth, the mezzo soprano Sara, the tenor Robert Devereux, and baritone Duke of Nottingham.

Elizabeth I’s passion for her lover  Robert, Earl of Essex, drives the plot.  In scene 1, Elizabeth displayed the character of an imperious, fearsome, and proud monarch.  She held more power than anyone else in England.  Parliament sought to execute Essex as a rebel for treason.  The elderly Queen loved a younger man.  The Queen confided to Sara, a beautiful lady in waiting, that the Queen would pardon Devereux of the treason charges, if he still loved the Queen.

Devereux loved Sara.  Elizabeth had forced Sara to marry Devereux’s best friend and supporter, the Duke of Nottingham.   Trapped in a marriage she never wanted, Sara still loved Devereux.   At their secret meeting, a duet between Sara and  Devereux supplies one of the opera’s high points.   Delightful flute mirrored the intense love they shared.  Telling him to flee, that they must never meet again, Sara gave Devereux, as a token of her love, her blue shawl.

By order of the Queen, Sir Walter Raleigh arrested Devereux.  Raleigh discovered Sara’s blue scarf.  The scarf proved Devereux loved a woman.  Blind with rage and jealousy, Elizabeth signed Devereux’s death warrant.

Recognizing his wife’s scarf, the Duke of Nottingham, drunk in his palace, assaulted Sara with a knife and threw her about.  Devereux’s unwise passion for Sara turned against him his best supporters – the Queen and his former friend the Duke of Nottingham.

Still in love with Devereux, too late, the Queen canceled his execution.   Moments before the executioner chopped off Devereux’s head, she pardoned Devereux.  A cannon shot signaled his death.   The Queen saw visions of Devereux’s headless ghost and a bloody crown.

Elizabeth could not order Devereux to love her.  Even the greatest power meets limits. In the background of the stage statues symbolized Time and Death. Renouncing her throne, she exclaimed “Let James be King!”  A blast of the orchestra’s brass marked her death.

Setting a fast and thrilling pace, the Queen’s transforming feelings supply the opera’s dramatic tension.  Her love transformed into fury, regret, sorrow, remorse, despair, and finally madness.  Donizetti called this work, “the opera of emotions.”

I,Too, Am America

Art Showcase, Authors, Blog, English, Poetry, Society

Martin Luther King Jr.’s Method and Goal, was to give the African American people a voice, to help them stand up, and , much like Booker T. Washington, to give them a way to build their way up to the top of the social structure, to prove themselves worthy of high positions.

His Intentions and motives, therefore, are best explained in the poem ” I, too” by Langston Hughes.

So, in honor of Martin Luther King Jr. Day this year, I present to you a Spoken Word Animation and Montage of the Poem ” I,too”. Below it, is the full text of the poem.


I, too, sing America.


I am the darker brother.
They send me to eat in the kitchen
When company comes,
But I laugh,
And eat well,
And grow strong.


I’ll be at the table
When company comes.
Nobody’ll dare
Say to me,
“Eat in the kitchen,”


They’ll see how beautiful I am
And be ashamed—


I, too, am America.
– Langston Hughes

A Poem by Omar Abdelhamid

It is Monday.  

The sky is freshly rolled out

the air is soft and silent

A single crimson leaf

dances above my head


And the world is in front of my eyes

but my arms cannot reach out and grab it


I am a speck in the ground below

Some hear my whispers

Stoop down to listen.

Pick up the words I drop

And place them into my humble basket


  1. Am.  Sinking.

My arms and neck  are stuck in the cement

I cannot reach out, nor do I have a soul to lift me

I am bound to something, something more than me

and it rushes through my bones

through my mind bouncing back and forth and breaking through every thought every memory

And I can feel the frozen bodies of those who fell behind me,  screaming, hoping,

 leaving their legacies

to be plucked by the vulture time

who eats his meal with no haste

they leave it for me

for me  to drop

and for you to stoop down,

pick up, and place into my humble basket


They will find me here

if they care to look


a moment in time

an echo, a memory


And every echo is smaller

when there is no one there to hear

please hear


Send help

Give my words a way

To break me out

out of this cage

A Short Story by Omar Abdelhamid

      Exhausted from the walk and relieved to have found a seat, I braced myself for the roar of the train as it took off. Suddenly we were in the dark, and I could spot blotches of graffiti on the inside of the tunnel as we whizzed by. I could not think, because my thoughts,unable to keep up with the speed of the iron beast, were left to float in the emptiness of the tunnels, to be ignored, if even noticed, by later commuters. The screech of the friction of the rails as we shot through exhausted my mind, until I could see nothing, I could hear nothing, and I could know nothing. And West shot the beast towards home.

Are We Who We Think We Are?

My name is Omar Abdelhamid. But is that really who I am?  Is Omar, the Omar that speaks to others and shares opinions and ideas the whole of my being? Or is Omar just one of the many functions of my human self? And does this self, this communicative, social self, really physically exist?
