What was first: energy or the Big Bang?


The problem with cosmology is the universe’s size. When we think that gravity stretches light that means that massive objects seem to be at longer distances than they really are. The virtual redshift means that massive objects stretch light waves. And that means we see light as more red because of that effect than it really is. So because gravity stretches light all objects seem to be more red than they are.  When we look at objects from different angles the gravity and curvature of light make images distorted. Black holes pull light waves almost straight. And it's possible. The massive gravity pulls electromagnetic radiation longer so much that the visible light or IR radiation turns straight into radio waves. 

Did photons or energy exist before the Big Bang? The answer is that energy cannot come from anywhere. So there should be some kind of wave movement that focuses on the event where material and energy formed in the form as we know them. When we think of the Big Bang as a series of events that turned material and energy into form as we know them, we must realize that even if the Big Bang was only one single event there could be material that is impossible in our universe. In the just born universe energy level was higher. 



And maybe the higher energy quarks like bottom and top quarks could form short-term material like “hydrogen”. Their top quark and bottom quarks form the “proton” and the muon orbits that structure. Those things are impossible in the modern universe. And those structures vanished just after the Big Bang. Just after the Big Bang formed matter and antimatter. Then those particles and their mirror particles formed giant annihilation. So maybe the asymmetry in the wave-particle duality happened when some event like a primordial black hole pushed a little bit of material away from the antimatter. That great annihilation can form black holes because their energy level is so high. 

There are models of the Big Bang as a series of events, and some astronomers searched the place where that event happened. But there is no visible evidence of that place’s existence. There are theories that maybe some material formed a black hole just after the Big Bang. And that black hole could form the center of the universe. The idea is taken from the nuclear bomb explosions. When the Big Bang happened it pushed material into a ring-shaped structure. 



There formed a massive quantum vacuum or cosmic void in the middle of that ring. Then part of the material could fall back to the point where the Big Bang happened. When we think about models there the Big Bang was a series of events. We can imagine a situation where in the space before the Big Bang two strings or superstrings impacted. That impact formed the ring-shaped string called a photon. That photon started to form a quantum vacuum in it. Then that thing caused an effect where the quantum fields started to focus around that point. Then that energy broke out from that point. 

There are also models where the giant “photon” surrounds our universe whose geometrical shape can be like some kind of flat disk. The normal model says that the photons were formed seconds after the Big Bang. So could photons exist before the Big Bang? That could require the existence of the multiverse. The thing is that if those “photons” existed before the Big Bang I must say that they might have very little thing to do with the modern photons. And maybe the Big Bang began when those things formed. 

In String and Brane-theories the thing that began the Big Bang was the hole that formed in the wave movement before the Big Bang. That hole caused the upper Brane or dimension to fall through the energy bottom and smash with that wave movement. That pushed energy into that point forming the particles and energy. So, particles are droplets from the energy impact that happened a long time ago. 

The expansion of the universe supports superstring theory where the universe exists in the giant superstring. That expansion happens because the universe and material release energy into supersting.  In the newest theory time is the only real thing in the universe. And that means everything happens in and because of time.

Quark stars, black holes, and invisible light. (How gravity stretches light)


How gravity stretches light? 

Can some red dwarfs be quark stars? Quark star's gravity, or virtual (gravitational) Doppler effect stretches light so much, that it can turn to look like red. 

"A quark star is a hypothetical type of compact, exotic star, where extremely high core temperature and pressure have forced nuclear particles to form quark matter, a continuous state of matter consisting of free quarks." (Wikipedia, Quark Star) 

"The Doppler effect (also Doppler shift ) or Redshift is the change in the frequency of a wave in relation to an observer who is moving relative to the source of the wave. The Doppler effect is named after the physicist Christian Doppler, who described the phenomenon in 1842. (Wikipedia, Doppler effect)

A common example of Doppler shift is the change of pitch heard when a vehicle sounding a horn approaches and recedes from an observer. Compared to the emitted frequency, the received frequency is higher during the approach, identical at the instant of passing by, and lower during the recession. " (Wikipedia, Doppler effect)

What if something stretches radiation as much as its wavelength turns straight? Black holes can make that thing near their event horizon. That is one of the most important things in the black holes' gravitational effects. The massive or extremely strong gravitational field stretches light so much that we cannot see even the event horizon. 


An animation illustrating how the Doppler effect causes a car engine or siren to sound higher in pitch when it is approaching than when it is receding. The red circles represent sound waves. (Wikipedia, Doppler effect) 

There is no limit to how much the redshift can stretch light or wavelength. There is a possibility that strong gravity fields along fast movement away from the observer can stretch the light straight to radio waves. But can this kind of extreme Doppler effect be possible? 

Strong gravity fields can cause the Doppler effect that visible light spectrum goes to the electromagnetic spectrum's red side. When the Doppler effect stretches radiation it makes the same thing as the strong gravity field. A strong gravity field can transfer all visible radiation that comes from an object into the IR area and that can cause interesting theory. 


"Absorption lines in the visible spectrum of a supercluster of distant galaxies (right), as compared to absorption lines in the visible spectrum of the Sun (left). Arrows indicate redshift. Wavelength increases up towards the red and beyond (frequency decreases)." (Wikipedia, Redshift)

"In physics, a redshift is an increase in the wavelength, and corresponding decrease in the frequency and photon energy, of electromagnetic radiation (such as light). The opposite change, a decrease in wavelength and increase in frequency and energy, is known as a blueshift, or negative redshift. The terms derive from the colours red and blue which form the extremes of the visible light spectrum. " (Wikipedia, Redshift)

"The main causes of electromagnetic redshift in astronomy and cosmology are the relative motions of radiation sources, which give rise to the relativistic Doppler effect, and gravitational potentials, which gravitationally redshift escaping radiation. All sufficiently distant light sources show cosmological redshift corresponding to recession speeds proportional to their distances from Earth, a fact known as Hubble's law that implies the universe is expanding." (Wikipedia, Redshift)





"Illustration of the interior of a neutron star and a strange quark star" (Wikipedia, Strange star)

"A strange star, also called a strange quark star,  is a hypothetical compact astronomical object, a quark star made of strange quark matter." (Wikipedia, Strange star)

"Strange stars might exist without regard to the Bodmer–Witten assumption of stability at near-zero temperatures and pressures, as strange quark matter might form and remain stable at the core of neutron stars, in the same way as ordinary quark matter could. Such strange stars will naturally have a crust layer of neutron matter. The depth of the crust layer will depend on the physical conditions and circumstances of the entire star and on the properties of strange quark matter in general. Stars partially made up of quark matter (including strange quark matter) are also referred to as hybrid stars." (Wikipedia, Strange star)

The collapse of the crust layer of strange stars is one of the proposed causes of fast radio bursts." (Wikipedia, Strange star)


Electromagnetic Spectrum 

It's possible. That hypothetical quark stars look like red dwarfs. That makes them so-called red false dwarfs. Or maybe it can stretch radiation so much that the visible light's wavelength moves to IR or even radio wave areas in the electromagnetic spectrum. We know that strong gravity fields cause a virtual Doppler effect that makes the wavelength stretch. 

Can some red dwarfs be those hypothetical quark stars? If a quark star's gravity is strong enough it can turn the object red. So how can we prove that thing? Red dwarfs are small and light stars. So to confirm that the object that we think of as a red dwarf is the quark star we need to find a binary star where white dwarfs or neutron stars orbit the red dwarf. 

Normally neutron star or white dwarf is the mass center. The mass center is the gravity center. That means normally red dwarfs orbit white dwarfs or neutron stars. But if that happens oppositely. That red dwarf is the mass center which means its gravity can be so strong that it stretches light into red. 

But same way one, very heavy but hypothetical object called a quark star can stretch light. Can it be possible that the hypothetical quark stars have so strong gravity field, that they can stretch or turn even UV radiation into radio waves? 

In some models, the quark star can be invisible. The idea is that the quarks form the quark star's shell. Quark stars would be the only places in the universe where quarks are free. In other places. Those particles are tied inside hadrons. The reflection that comes out from the quark stars comes from quarks. In regular material. That reflection comes from hadron quantum fields. It's possible that radiation that hadrons send just slides over the quark star. 

Or the particle that causes reflection is so small that we cannot see that thing in a quark star. If energy reflection comes straight from a quark it travels straight through Hadron. There is the possibility. That also other fields. Except gravity slides over those quarks. That form structure. That seems like it's covered by small half-balls. When energy travels or slides over the structure it denies reflections in wavelength that we can see it. 

There is a model that quark stars are mediums between neutron stars and black holes. The thing is that those hypothetical quark stars can stretch radiation as much as their wavelength turns so long that we cannot see it. 

Or we cannot detect that radion because some other things cover it. In some models, photons can travel through those free quarks. The gravity field around those hypothetical quark stars would be powerful. But that gravity field stretches radiation and it can make it possible for the quark star can be invisible to the human eye.

Thermophotovoltaic cells can make energy production more effective.


"Researchers are exploring thermophotovoltaic systems that generate electricity from heat, highlighting their potential in sustainable energy." (ScitechDaily, Harnessing Heat for Clean Energy: The Future of Thermophotovoltaic Technology)

"Researchers are advancing thermophotovoltaic (TPV) systems, which convert heat into electricity using photovoltaic cells, presenting a silent and low-maintenance energy solution." (ScitechDaily, Harnessing Heat for Clean Energy: The Future of Thermophotovoltaic Technology)

Thermophotovoltaic cells allow to use of laser beams to transport electricity to drones and other electric components. Thermophotovoltaic cells are applications that can increase the energy efficiency of the engines and electric supply systems.  

Thermophotovoltaic cells convert heat to electricity. Those systems can operate independently. 

Thermophotovoltaic cells can operate with regular energy sources using their heat to make electricity.  

They can harness energy from boiling water from the water supply system. And the small robots. Observe the system conditions can use those tools for energy supply. 

The thermoelectric photovoltaic technology can collect energy from the engine of the hybrid cars. That system can harness energy from the combustion engine's heat. And it can boost the engine efficiency. It also loads batteries faster. 

The fact is that thermophotovoltaic technology can increase the energy efficiency of all power plants. Engineers can use this kind of system to make new points where they collect energy. And if thermophotovoltaic cells can someday turn to large-scale use those systems can harness energy from geothermal holes. 

Also, dark layers can give energy to thermophotovoltaic cells.  That can used together with regular solar panels. The thermophotovoltaic cells can collect energy from blast furnaces which decreases the need to buy electricity.  

Thermophotovoltaic cells can also be used in next-generation Venus landers. Those systems can also give energy to robots that operate in high-temperature environments. There are many potential useful things for that technology. The ability to turn heat or IR radiation into electricity can be useful in military applications that require low-observable energy sources that don't operate in radio frequency. 

That means. The IR-laser system can deliver electricity to small drones or other electric equipment. Those drones can operate in caves and places where they cannot land. The ability to use laser beams to load electricity to the small quadcopters is one of the most fundamental ideas in robotics. Those lasers can also be used to transport information to drones. The system can have multiple useful applications. From the scientific to the military world.
