I find it funny that Lawrence Krauss is able to literally talk about nothing and keep me entertained.

[Thachosennee]

Save yourself time, Krauss's nothing isn't an actual "nothing". 

[troydrury]

Atheists would rightly mock theists for making such a vacuous argument.

[captainjack]

So it turns out "nothing" is in fact something. He's playing with words, or rather, mixing philosophical notions with scientific concepts

[maldbai]

why did i have a feeling that what he said was just bullshit and that he didnt really get what everybody means by nothing?

[jesipatrocinio]

Correct me, Nothing doesn't exist actually? Because Quantum mechanics demands that something is always popping out? So Nothing is an impossibility.

[MegaTattoo]

God wishes he were as intelligent as  Lawrence Krauss.. :) 

[LIQUIDSNAKEz]

1:13 Exactly, but those quantum mechanical variables that fluctuate in and out of "existence, " as abstract as they may be, STILL count as "something, " which means that "Something" has always existed. "Nothing, " by it's very nature is simply not a reality.

[danbike]

What Larry speaks about is not science. Science is about observation and being able test theories. His nothing is "nothing", which is something. We know through observation that something can not come from nothing in the material natural world.

[SpatialAndTemporalEvangelicals]

Then Nothingness Will Recreate My Conciousness After Death.
My Conciousness Will Come Into Existence Out Of Nothing Once Again.

position is more important that space, as actvities are just outcome of interaction and instances in given position/location, an empty position is nothing. ex. 1) a location out of the universe where no energy has reached yet. 2) a location for limited time inside the universe when there is no energy at that position.

[ucantseemed]

So *REDEFINING LOGIC AND DEFINITIONS* is what's considered science today lol, the world is doomed.

[mikewolfkin]

You say that Martin Rees says that if gravity was less, stellar fusion couldn't happen because there wouldn't be enough force to push atomic nuclei together. If the electromagnetic force were reduced, suddenly the force of repulsion that causes proton to repel proton and electron to repel electron and resists atomic fusion also reduces. In other words, fusion would not need as much force, meaning that even with less gravity, stellar fusion could still be possible.

[iamfrancisrice]

Consistent with their beliefs? You mean consistent with science. The whole point of this video is that the philosophical concept of nothing (which he explained at the beginning of the video) may not actually exist. If it did exist, there would be no laws of physics, so the law that "something can't come from nothing" wouldn't apply, so something could come from nothing. However, it's also possible that there never was nothing, and that what we called nothing was always something.

[Samzz]

He knows the point. Krauss proposes empty space is 'nothing' when it is in fact a Sea of Energy and a Sea of Energy is SOMETHING, it is not 'nothing' because 'nothing' has NO properties whatsoever, so now we know Empty Space is actually something. He is trying to bring a new meaning to the word 'nothing'. From a scientific mind this makes perfect sense because it is based on what we observe... but this is also why philosophy is necessary.

[careywaldie]

This guy is a goof. Nothing comes from nothing. Nothing ever will.

[danieljanca]

"...in fact, nothing is a physical concept because it's the absence of something, and something is a physical concept." - Dr. Krauss

If "something" is a physical concept, of which "nothing" is the absence, then "nothing" is the absence of a physical concept, ergo not a physical concept. "Nothing" is most correctly described as not anything.

[Hnthal]

What Lawrence is implying is that believing in the philosophical definition of "nothing" - which incredibly for people here in the comment section is even more 'nothing' than no space, no time, no laws, no matter, no radiation - is the same as believing in god. There's no evidence of this definition of "nothing" and it doesn't even exist in physics. The concept is untrue and should be left behind. And quite frankly, our human urge to find this "nothing" is exactly that, a human urge. The same urge that makes us trying to find a preexisting meaning for our universe which resulted in creating gods.
