Is the Universe a Wave Accelerating towards a Peak?

AI Thread Summary
The discussion explores the concept of the universe behaving like a wave, specifically an electromagnetic sine wave, which accelerates towards a peak before deflating. It raises the possibility that dark energy could represent an alternate wave orthogonal to the universal wave. The idea is presented as a speculative musing without established scientific backing, emphasizing that the universal wave function theory lacks current support. Participants are encouraged to provide recent citations if they disagree with this assessment. Overall, the conversation highlights the speculative nature of the universe's behavior in relation to wave dynamics.

could the universe act like a wave that at the present time is accelerating towards a peak something akin to an electromagnetic sine wave? And once the peak is reached it starts to deflate? Could this dark energy be the alternate wave that is at right angled to the universal wave?
Just musing while I'm exercising.

zero is not fact
zero mining noting
this is no faund in any place and any time
 
The universal wave function thing is an old theory with no legs. Give recent cites if you disagree.
 

Thread 'Matter density right after the decoupling'

https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.

Thread 'Hubble Constant, Dark Energy and the Expanding Universe'

Why was the Hubble constant assumed to be decreasing and slowing down (decelerating) the expansion rate of the Universe, while at the same time Dark Energy is presumably accelerating the expansion? And to thicken the plot. recent news from NASA indicates that the Hubble constant is now increasing. Can you clarify this enigma? Also., if the Hubble constant eventually decreases, why is there a lower limit to its value?
