Is Nothing Still Considered Something?

The discussion revolves around the philosophical and scientific implications of "nothing" and whether it can be considered "something." Participants explore the concept of vacuum energy, suggesting that true "nothing" cannot exist within the universe, as there are always particles and energy present. The Big Bang is discussed, with questions raised about what it is expanding into, leading to the conclusion that it is expanding into "nothing" or "everything," as the universe itself encompasses all. The conversation also touches on the definitions of the universe and the observable universe, debating whether the observable universe can be equated with the entirety of existence. Ultimately, the thread highlights the complexity of understanding cosmological concepts and the challenges of defining "nothing."

That is fundamental to science. Many breakthoughs in science started out as little more than a 'crazy' ideas, until someone figured out how to test it. It seems almost unfair that the one who figures out how to test a new idea is more likely to get a Nobel than the one who came up with it.

Yes I alwasy thought it was , for example, terribly unfair that someone like Ralph Alpher didnt get a Nobel prive for the CMb whereas Penzias and Wilson did. Not saying that latter didnt deserve theirs but I think you get the point.

It is because - as demonstrated by the popularity of physicsforums and sciforums for amateurs - ideas are a dime a dozen. It's the verifiability that gives an idea teeth.

The universe is composed of MATTER, ENERGY, SPACE, AND TIME. Beyond the universe is no matter, no energy, no space and no time (NOTHING). NOTHING is the key to the unified theory and needs to be studied! It is not composed of dark energy. That is what space is made of. The universe expands because as light or fields (e.g., gravitational, electromagnetic, etc) travels it creates space and time and is also energy and matter. Beyond where the universe's light/fields has expanded is NOTHING.

The unifying thread to Matter, Energy, Space and Time is Nothing. Matter, Energy Space and time are linked inseparable from each other.You can not have matter without space and time. You can not have space without matter, energy and time. But you can have Nothing only without matter, energy, space and time. E=MC^2

The study of Nothing needs to be pursued. It is the missing key to understanding everything.

...What? I don't think you understand what it means that the universe is expanding. The universe doesn't have a boundary, it's that the space in between galaxies expands, increasing the distance in between everything. There isn't anything known as 'Nothing'.

You would do well to read some actual physics instead of just making things up. The FAQ section here in the Cosmology subforum would be a good start.
