Then is potential energy infinite (potential energy=energy that can be created)
There is no potential energy creation in the creation of "dark energy" so I don't see that your "potential energy=energy that can be created" is a true definition at least certainly not in this case.Noduagga said:Then is potential energy infinite (potential energy=energy that can be created)
So how would you call the energy that could be created? Would it be infinite?phinds said:There is no potential energy creation in the creation of "dark energy" so I don't see that your "potential energy=energy that can be created" is a true definition at least certainly not in this case.
Only if the universe is infinite. What are you really trying to get at?Noduagga said:So how would you call the energy that could be created? Would it be infinite?
Ok I think we aren't understanding each other. Correct me if I'm wrong. As universe expands and more space time appears more dark,vacuum and gravitational energy appear too right? So, if expansion has no limit (universe can expand forever) then these energies could be created with no limit right? Infinite energy could appear right? That infinite energy that can appear with expansion is what i called potential energy...so...?phinds said:Only if the universe is infinite. What are you really trying to get at?
If the universe is infinite they you don't need to wait ... the DE is ALREADY infinite. I still have no idea why you call it potential energy. Do you mean that there is the potential for infinite energy? If so, you are using a completely non-standard definition of the phrase "potential energy".Noduagga said:Ok I think we aren't understanding each other. Correct me if I'm wrong.

Well supposing that universe is finite and expanding.phinds said:If the universe is infinite they you don't need to wait ... the DE is ALREADY infinite.

If the universe is finite then an infinite amount of DE would take an infinite time to create.Noduagga said:Well supposing that universe is finite and expanding.
And yes that was the thing i meant to say. If calling it potential energy is incorrect what term should i use?
I called it potential energy because i didn't find another way to name it but i knew it was somehow incorrect that's why i asked the question..so how could we name it?phinds said:If the universe is finite then an infinite amount of DE would take an infinite time to create.
Do you understand the normal meaning of "potential energy"? If not, you should get clear on it.
Just describe it, exactly as you would do for any phenomenon or complex set of events for which there is no single name.Noduagga said:I called it potential energy because i didn't find another way to name it but i knew it was somehow incorrect that's why i asked the question..so how could we name it?
ok, you're right but just one last thing. if infinite energy can be created, could we say that there's (potentially) infinite energy ?phinds said:Just describe it, exactly as you would do for any phenomenon or complex set of events for which there is no single name.
In an infinite universe or in an infinite amount of time, there can be infinite most anything. What IS this fascination you have with infinite energy? What's the point? Do you have some personal theory that you are trying to find support for?Noduagga said:ok, you're right but just one last thing. if infinite energy can be created, could we say that there's (potentially) infinite energy ?
So, would we be correct if we say that energy is (potentially) infinite?phinds said:In an infinite universe or in an infinite amount of time, there can be infinite most anything.

WHY DO YOU KEEP DOING THIS ? What IS it that makes you keep trying to get people to tell you that there is infinite energy. What does it matter? Did you not believe Chronos' telling you that it it irrelevant and only the energy density matters?Noduagga said:So, would we be correct if we say that energy is (potentially) infinite?
When we talk about energy being created with expansion, we are referring to the idea that the universe is constantly expanding and this expansion creates energy. This is known as the cosmological constant and is a fundamental concept in modern physics.
According to the laws of thermodynamics, the total energy of a system is constant. However, as the universe expands, the energy density of the universe decreases. This decrease in energy density is equivalent to energy being created. This energy is often referred to as "dark energy" and is thought to make up about 68% of the total energy in the universe.
The current understanding is that there is no limit to the amount of energy that can be created through expansion. As long as the universe continues to expand, energy will continue to be created. However, it is important to note that this energy is not created out of nothing, but rather from the decrease in energy density as the universe expands.
The concept of energy being created with expansion is closely tied to the Big Bang theory. According to this theory, the universe began as a singularity and has been expanding ever since. As the universe expanded, energy was created and this energy is what allowed for the formation of galaxies, stars, and other structures in the universe.
The idea of energy being created with expansion has significant implications for our understanding of the universe and its evolution. It helps to explain the current rate of expansion of the universe and the presence of dark energy. It also has implications for the ultimate fate of the universe, as some theories suggest that expansion could eventually lead to a "big rip" where the universe tears apart due to the continued creation of energy.
