"You may measure the frequency of normal visible light as so high that in your frame, the wavelength is less than the Planck length. " Thank you for that. Hypothetical frames of reference. I can't think of any hypothetical frames of reference that would apply, rushing in toward the point-like...

Thank you. I hope I'm not transgressing to ask if this means the constant is a mensuration issue not a physical constant or limit of any kind?

Is it known how much momentum a photon possesses if it's wavelength is at the Planck length, and what happens if it's momentum is somehow increased from that?

Your comments are illuminating. My thinking is stuck here on a, "What if?". What if there is no quantum of space? Having little imagination, all I come up with is that space must be purely a geometric result of mass energy. When I write, "stuck", I refer to the fact that I come to this vague...

Again, thanks. I've been looking around at what is available to quantum pictures and what is not. Along that line I've wondered about the "quantum nature of the vacuum" and if that has anything to do with the "quantum nature of space" or if space is considered as a geometric feature that's not...

Thank you for your replies. Can I take from this that unlike quantum gravity, quantum frame drag is not an area of inquiry, especially not in the case of non-massive objects?

It doesn't seem likely given that electrons in copper wire move even faster and i can't find anything on electric circuits creating frame drag. I don't expect anyone to tell me why there is no micro-frame drag . Likely the question itself contains some false assumptions. And thanks for your...

Sounds right. "Blanket"? Do you have a synonym? I haven't thought about design. Assuming that one is projecting an image on a surface, it seems like it would a nice trick to somehow exclude any disc at all from appearing on the image. I have no idea how to bend light around corners but perhaps...

For instance, if you put a big "magnifying glass" above the atmosphere in the shadow of a total solar eclipse thus blocking out light from the "surface of the sun", could you heat an object to a temperature hotter than the surface of the sun? Applying the Second Law, one can't raise the...

Help! Why doesn't potential equal expansion?

The minimal necessary math to describe the potential path of an electron expands over time. Second by second, the space necessary to describe the possible positions of the electron expands. . Does that imply expansion of physical space? And does that shift the explanation of the expansion of...

It's your site. You don't have archives? Please! i'm not going to go thru this again. GR. GR. GR. Huh?

Thanks for responding. But i can only go by my measly memory and a couple of GR guys came up and said i was not welcome, and so now I'm gunna ban myself again for a couple of years. Being not welcome and all. . It's not a hard question: Do particles create more space by just sitting there...

Let's just go back to why i even showed up on this site. i kept getting messages from physicsforums informing me that i was seriously missed. Now i wonder if perhaps that was not entirely accurate. . You want a "reference". i can't find it now. i watched Smolin's 90 minute long lecture...

i refer you to Smolin. He saw an "emergence" of space, given the assumption that time is real.
