So do you have an evidence that a thing can exist from nothing?
Straw man, FearGod.
I have never made any claim whatsoever that thing exist from nothing.
As I have told you earlier (previous reply), with the current technology, science only have evidence for what can be "observe", which is the OBSERVABLE UNIVERSE.
I would suggest you read up on "observable universe", and at the same time look up "quasar", "cosmic microwave background radiation" (CMBR).
The CMBR is remnants of thermal radiation (heat) of the earliest detectable electromagnetic waves (eg light, photon, microwave) that was said to be evidence for expanding universe, hence the Big Bang model. CMBR occurred 370,000 years after the Big Bang, known as the
Recombination epoch.
Recombination is a period, when electrons first bind themselves into ionised atoms like hydrogen and helium, creating the first stable matters. An atom is ionised when it has no electron(s); just proton(s) (and possibly neutrons for ionised helium; there are no neutrons in hydrogen) enclosed in the shell known as nucleus.
Getting back to Recombination epoch, when electrons bind themselves to ionised hydrogen atoms, energy occurred where it will emit light. Light produced energy in the form of thermal radiation (heat). Visible light (electromagnetic waves) as they age and travel through space, the waves attenuated or get stretched, shifting the waves from visible to infrared to microwave waves; this natural phenomena is known as
red shift.
It was Edwin Hubble who discovered the red shift in 1929, as sign and evidence for universe is expanding and galaxies moving away from each other.
CMBR was first predicted in 1948, by two scientists, Ralph Alpher and Robert Herman, with the help of George Gomow (Alpher's mentor and professor), but it was only discovered in 1964, by Arno Penzias and Robert Wilson, which they received Nobel prizes for their discovery in 1978.
CMBR have been a number of times, on several different missions of space telescopes -
- Cosmic Background Explorer (COBE) - 1989 -1993 (NASA)
- Wilkinson Microwave Anisotropy Probe (WMAP) - 2001 - 2010 (NASA, ESA)
- Planck - 2009 - 2013 (ESA)
With each craft, they get a better images of the Cosmic Microwave Background Radiation.
Below is the last (Year 9) image in 2012 of CMBR from WMAP:
My point is that, although Alexander Friedmann (1922) and Georges Lemaître first predicted the expanding universe model (Big Bang), we are only just started our discoveries, and it take time, for our technology to catch up with the theoretical theory.
A new space telescope will be launched in 2018, called James Webb Space Telescope (JWST) will be more advanced than all previous telescopes. Perhaps it will uncovered more earlier epochs of the Big Bang, perhaps we will finally observe for the first time, dark matters.
Hopefully I will still be around when they show the latest images JWST.
My point in all this, we don't know what exist before the Big Bang began, but it is certainly not this "nothing".
