Questions related to Cosmology

Are there any candidates for an Einstein's bare cosmological constant?

It is commonly accepted that General Relativity has its own 'bare' cosmological constant that contributes together with the cosmological constant resulting from vacuum energy density for an...

How Does The Higgs Field Relate To The Dirac Sea Of Energy?

Dirac and others combined the physical properties of vacuum space to predict a large energy in space, sometimes described in Planck units. Other researchers looked into the vacuum and found little...

General relativity: A reduction in the Strength of Gravity for Dense Matter?

General Relativity. Can the strength of gravity reduce for dense masses? New discussion Is there anything in Einstein’s Field Equations that allows the strength of gravity to reduce for regions of...

What is the effect of the large scale of behavior particle in a magnetic field?

As it is known there is a magnetic field in large scale universe, so the particle undergoes a magnetic field will be different in case of expanding universe or static one as it will be in the...

Cryodynamics has revolutionized Cosmology ?

It has radically altered it by rehabilitating Fritz Zwicky 1929. Hence ten Nobel medals are gone. And cheap energy for all is made possible. Provided, that is, that humankind is capable of...

Why does the universe expand despite self-gravity?

We are in an expanding Universe as per the big-bang cosmology. Does it really mean that the outward thermal pressure now beats the inward gravitational pressure in the Universe? What is the exact...

Humankind has a collective IQ Problem ?

HIQ is the best name for it, composed out of HI and IQ. "HI" means "I am laughing" in the language of hams (radio amateurs) that I acquired 63 years ago. And IQ (for "I quit") stands for where...

What to do if you discovered a 90 Years’ Lemmings Road ?

Ten disproved Nobel medals render so many laureates along with Stockholm and Sweden itself your idol’s personal enemies. My hero is Zwicky who outwitted humankind ever since 1929. The new...

If there is a speed of light, is there a speed of darkness? Do shadows move as quick or faster?

If we consider hypothetically and philosophically, i.e., why we always think light is spreading out. May be dark is fading away as an entity everytime faster than the light. Why faster? Because we...

Is c-global retrieved a Benefit or a Curse ?

c-global retrieved is the consequence of a fourth mega implication of Einstein 1907 having been found belatedly. It has mega implications. For example, no cosmic expansion any more, with belated...

Is there empirical Evidence that the Cosmos is infinitely old and large ?

The answer is yes. A first example is the ultra-weak X-ray sources of Riccardo Giacconi’s which are equi-distributed across the sky. Another is the so-called “dark galaxies” which are actually...

How are Einstein field equations modified with varying c, G and Λ?

We have derived from certain astrometric and cosmological observations how physical constants evolve in time (https://doi.org/10.3390/galaxies7020055). The theoretical basis used is rather...

Is there a paper on what fraction light velocity is attributable to distant observed mass?

All mass produces time dilation, and a reduced velocity of light isotropically, and for distant mass the effect is proportional to the inverse radius. In addition there is a radial reduction in...
