Did a Pre-Big Bang Species Cause the Big Bang Theory?

[Plagosus]

Day-dreaming the other day, I postulated a possible explanation for the controversial Big Bang Theory. Because an object attains infinite mass when it reaches light speed, is it possible that a pre-big bang species reached light speed (or near) and the affected object achieved infinite mass (or near), effectively drawing everything in the universe to it, in one all-encompassing bang? Please forgive me if my hypothesis lacks consistency or sense, because of my relatively poor science background.

Welcome to Physics Forums, Plagosus.
Usually, these kinds of topics are discussed in the "theory development" forum.
I'll move it there now.

Plagosus,

The Standard Big Bang created not just matter but also radiation (photons), which were light speed from the beginning until now. This theory could not explain why matter in the forms of planets, stars and galaxies do not have high translational velocity. As a matter of fact, the galaxies are not really moving, it's the surrounding space that is expanding. And this expansion is greater than light speed the farther away the galaxies relative to our observations.

The Inflationary Big Bang attributed the bang to the existence of negative pressure creating the inflaton field. This negative pressure is similar to the force of antigravity.
And it is related intimately to the cosmological constant \Lambda of general relativity.

Thanks for the explanation, and sorry for posting in the wrong forum.

When physicists talk of the infinite amount of energy needed to attain light speed, and the infinite amount of mass created as a result, are they describing infinite as the total energy and mass in the universe, because is there not a finite amount of the two?

Cosmologists are still looking for the missing mass (dark matter) and energy (dark energy) that the universe should have in order to form a closed spacetime geometry. That is to say that \Omega greater than unity. The omega is defined as the ratio of the observed mass-energy density of the universe to the critical density needed for each geometry.

Plagosas - Infinite means 'undefined'.

BBT is still an unproven theory, based on the premise that stellar redshift is due to the Doppler Effect, (an expanding universe); however there are numerous other causes of redshift, and the type of redshift apparent in starlight may very likely be due to either the Compton Effect, or Shapiro Effect

so don't be so sure there ever was a Big Bang or that the universe (or even the visible universe) is expanding

nobody knows one way or another
since no one was there to see it happen

"Infinite", Plagosus, means "undefined", ergo, any statement that "the mass of a particle achieving the speed of light becomes infinite" is merely a confession of self-ignorance of what really does happen. Don't ask me, hey, I was in Chicago went all that went down.

to discount the doppler effect as evidence of expansion challenges the validity of the doppler effect. when you offer a better explanation [along with the math], i will listen.
