Can matter and energy come from nothing? Why is there something rather than nothing?

[seriously disabled]

I think that when physicists say that something can come from "nothing" they actually mean that this "nothing" is something + laws of quantum mechanics.

 

But once you have a 'place' with certain laws then it is already not nothing.

Space-time only applies to inertial references. Space-time breaks down at a speed of light reference, where the universe appears like a singularity.

 

We also know mass cannot move at the speed of light; SR. Therefore mass cannot exist if we had a universe with only a speed of light reference. A speed of light reference has no mass.

 

Energy and photons move at the speed of light, but photons also show finite expressions that are inertial reference dependent. Wavelength and frequency of photons will red and blue shift based on inertial references. These are not dependent on the speed of light reference.

 

If we only had a speed of light reference in the universe, all photons of any wavelength will look the same, which is not how energy works. Their diversity needs inertial reference.

 

You can begin the universe from nothing by beginning at a pure speed of light, where there can be no mass and no distinction that we know as energy. I won't give the details because the rest is not mainstream but is more advanced because it can begin before the assumed t=0, where matter/energy and inertial appear.

what makes you think that?

 

so i guess GR is wrong then? /sarcasm

If there is nothing, then what is moving at the speed of light.

 

Or, to put it another way, please stop posting made-up nonsense.

OK, we've had enough speculative hijacks in the mainstream sections from you. From now on, your posts need to be approved by staff before they show up in mainstream sections, to make sure you aren't trying to introduce some unsupported and trivially wrong pet theory.

puppypower - that post is not going to be approved. Be aware that speculative answers to mainstream physics will not be tolerated in the main fora. Worse still - those parts in which you gave concrete "information" were blatantly incorrect. Either post this sort of message in speculations or do not post at all - but do not guess answers, make up stuff, and post it in the science fora.
