AI Thread Summary
Julian Barbour discusses his concept of Platonia, a timeless framework that seeks to reconcile quantum mechanics with general relativity by eliminating the notion of time. He emphasizes that understanding the universe requires a departure from traditional time-based perspectives. The Wheeler-DeWitt equation, which plays a crucial role in this discussion, notably lacks a time variable, highlighting the challenges of integrating time into quantum gravity theories. The conversation touches on the implications of the wavefunction of the universe and its relevance to Barbour's ideas. This perspective invites a reevaluation of fundamental physics principles.

an interview with julian barbour about his of platonia a world without time he argues that to unite quantum mechanics with general relativity we need to leave time alone.
here is the interview:http://noorderlicht.vpro.nl/wetenschap/smil/videoparts.sram?3626936+2848322+3855404+6882747+3250278

where may i find an explanation about the wheeler de-witt equation and why the isn't a mention to time in it?

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Mechanism of Energy Conservation in Zero-Amplitude Sum of EM Waveforms'

Assume that this is a case where by sheer coincidence, two sources of coherent single-frequency EM wave pulses with equal duration are both fired in opposing directions, with both carrying the same frequency and amplitude and orientation. These two waves meet head-on while moving in opposing directions, and their phases are precisely offset by 180 degrees so that each trough of one wave meets with the crest of the other. This should be true for both the electric and magnetic components of...
