Quotes About Cosmological theory

If we wish to understand Indian thought, we must return to its sources, that is, to the great civilization that preceded the arrival of the Aryans, which has continued to the present time and of which the Shaiva religion, the cosmological theory called Sâmkhyä, the practices of Yogä, as well as the bases of what we consider to be the Hindu philosophy, are part.

Despite its name, the big bang theory is not really a theory of a bang at all. It is really only a theory of the aftermath of a bang.

Hard-nosed physicists say that the six knobs were never free to vary in the first place. When we finally reach the long-hoped-for Theory of Everything, we shall see that the six key numbers depend upon each other, or on something else as yet unknown, in ways that we today cannot imagine. The six numbers may turn out to be no freer to vary than is the ratio of a circle's circumference to its diameter. It will turn out that there is only one way for a universe to be.

the universe may, in fact, be bigger than this, because the notion of inflation suggests that in the first second of its existence, the space-time in which the universe is embedded expanded much faster than the speed of light. If so, the real universe may be billions of billions of times larger than the observable universe.

If we can accept a single singularity of the Big Bang, on what basis can we reasonably claim no other such singularities are possible?

And since, according to the big bang theory, the bang is what is supposed to have happened at the beginning, the big bang leaves out the bang. It tells us nothing about what banged, why it banged, how it banged, or, frankly, whether it ever really banged at all.

The big bang is a theory, partly described in the last two chapters, that delineates cosmic evolution from a split second after whatever happened to bring the universe into existence, but it says nothing at all about time zero itself.

I, however, believe that there is at least one philosophical problem, It is the problem of cosmology

The standard model of particle physics describes forces and particles very well, but when you throw gravity into the equation, it all falls apart. You have to fudge the figures to make it work.

We need a theory that goes before the Big Bang, and that's String Theory. String Theory says that perhaps two universes collided to create our universe, or maybe our universe is butted from another universe leaving an umbilical cord. Well, that umbilical cord is called a wormhole.

A static universe isn't physically self-consistent.

His theory indicated that the universe would have to be either expanding or contracting, not staying static. According to his field equations, a static universe was impossible because the gravitational forces would pull all the matter together.

It now appears that the way the universe began can indeed be determined, using imaginary time.

If an extra dimension is rolled up into a circle, the mass of the lightest such particle would differ from the electron's mass by an amount inversely proportional to the extra dimension's size. That means that, the larger the extra dimension, the smaller the particle's mass.

If large extra dimensions solve the hierarchy problem, higher-dimensional gravity would become strong at about a TeV.
