Controversial claims should be supported by evidence or (at least) some kind of argument.
Pretending that controversial claims are established facts is promoting disinformation (or, at least, misinformation).
river has received an official warning for, yet again, making zero attempt to justify one of his claims about science.
Or maybe an infinite wavelength, a curve that never reaches its peak or plateaus.
Fielding in space because they can.
Trolling, trolling, trolling on the river...
A wave with infinite wavelength is not a wave but a flat line.
Ye, a curve from a wave/field
It would also have zero energy.
Can it provide gravitational potential energy to mass located in/on it?
So what is the physical mechanism that warps spacetime?
The presence of mass causes spacetime to pinch.
How? We're not sure yet.
I'm not sure what you're asking, BdS. What kind of physical mechanism are you looking for?
General Relativity is a theory that describes (among other things) why things with mass attract one another gravitationally. It describes that attraction as resulting from a curvature, or warping, of a spacetime manifold. GR is a theory, and the idea of a spacetime manifold is just that: an idea, or concept, used to explain and accurately predict observed phenomena.
Depending on what you mean, then, there are a few possible answers. Answer number 1 is that that General Relativity itself is the required "mechanism".
Answer number 2 is that some things in our universe have this property called "mass", and one of the functions of mass is to warp spacetime, so in that sense, matter itself is the "mechanism" - wherever there is matter, there will also be warped spacetime.
Answer number 3 would be whatever the answer is to the follow-up question "Yes, but why does matter warp spacetime?" This is where science parts company with philosophy. Science just says something like "We don't need to know that. It just does. That's what we observe that it does." Philosophy, on the other hand, goes down the rabbit hole, asking "Why is there mass and spacetime in the first place?" and "Why is there something rather than nothing?" and similar ontological questions. There are various ideas.
Define both space and time .
Space has always existed , otherwise there would be no manifestation of anything at all . Time is irrelevant . Its a measure not a real physical thing . Change time in any equation , it does change anything physical in the equation . For any change in time is based on converting the change in time in the equation into something physical .
A time based Universe could never exist . Because time comes from nothing . A time based Universe is mathematical . Time can not exist as form of movement at the beginning of the Universe from nothing . Nothing is non physical therefore will never have movement .
Therefore you can not warp , space nor time . Neither have physical qualities .
Not according to the big bang theory.
It seems real to me. Stuff doesn't all happen at once, as far as I'm aware.
But if it's not a real physical thing, then what is it, according to you?
I don't understand what you're trying to say.
What does "time based" mean?
How does time come from nothing?
What does it mean for a Universe to be mathematical?
Why should time exist as a "form of movement"? What does that even mean?
I agree with you that "nothing" does not move, because "nothing" doesn't do anything.
What do you mean by "physical qualities", and why do you think that time and space don't have them?
Your "therefore" doesn't follow from anything you said before.
Space is volume, which is 3 dimensional distance. Infinite volume (space) is inevitable. Claiming space started at the Big Bang is a pipe dream.
There is no alternative to infinite space. How could you possibly get rid of space, when it's nothing but distance?
Science has its head up its ass. Space can not be created and it can't be destroyed, it is simply 3 dimensional distance.
All of this strikes me as off-topic for this thread. If you want to have a rant about something else, perhaps start a new thread?

Something that makes logical sense and I know the question doesn't need to be answered by science for us to do science. We understand Gravity's effects and that is enough to do science. I'm just curious and like to try understand nature physically.
I ask a lot of questions and dont always expect an answer. If someone provides an answer, some on topic extra material, corrects my misunderstanding or gives their thoughtful opinion, great, it give me something to think about.
All of sciences current answers where once philosophy that "went down the rabbit hole" at a particular period of sciences progression. At some stage asking the question, "What are we made of?" would have sounded just as ridiculous as "Why is there mass and spacetime in the first place?" sounds now. Who knows, maybe someone thinking about "Why is there mass and spacetime in the first place?" leads them to some other theory that progresses scientific understanding.
Can you get a third object to orbit two orbiting objects? You got the Earth and Moon orbiting each other, can you get 3rd object to orbit the Earth Moon system? The 3rd object would be orbiting at a greater radius than the total Earth Moon systems orbital radius.
If a 3rd object can orbit the Earth Moon system, is the 3rd object orbiting the Earth Moon Barycenter?
The Earth and the Moon both have their own curves, is there another curve from their Barycenter?

I know . Which is why the BB theory is nonsense .
If I change anything physical in any equation , You change time ; If I change time in any equation the physical does not change . Hence time is not a real dimension .
Go outside and build a bonfire. Now start your stopwatch. When enough time elapses the wood will be ashes and the fire will go out.
You started with 5 pieces of wood, and 1 hour later all that's there are ashes.
So time elapsed and the wood is gone.
Put a gallon of gas in your car's empty gas tank and drive on the highway at 70 MPH. When you travel for about 20 minutes your car will run out of gas and you will be walking!
The gas is gone! Not recoverable! You turned gas into energy (power x time). Now let's see you turn that energy back into gas! Mass evolves to space!
What has this to do with time ?
