Re: Travel through wormholes is possible, but slow

Can someone point out where the article says why it's slower? I'm having difficulty unpacking:

"The new theory was inspired when Jafferis began thinking about two black holes that were entangled on a quantum level, as formulated in the ER=EPR correspondence by Juan Maldacena from the Institute for Advanced Study and Lenny Susskind from Stanford. Although this means the direct connection between the black holes is shorter than the wormhole connection—and therefore the wormhole travel is not a shortcut—the theory gives new insights into quantum mechanics."

Why is the wormhole not a shortcut?

Based on the colloquia I watched by Lenny Susskind, the problem is that you can put something into a wormhole, but to get it out the other end, you have to carry the encoding you get to the other end of the wormhole to decode the output. Because the distance to the singularity grows at the speed of light, the length of the wormhole is essentially infinite. It is only the operator you get from putting the object into the wormhole that lets it tunnel through that infinity, so no shortcut.

EDIT: Here is the lecture I'm referring to: https://www.youtube.com/watch?v=nEDFh8ma9zM

So we've uncovered the universes version of cyptography?

> Because the distance to the singularity grows at the speed of light,

doesn't our universe expand at the same speed?

When ever I think of traveling through a wormhole/blackhole, I imagine you would be squished and crushed and come out the other end as pure vaporized energy.

This makes me wonder, if there is the potential for our beings (or things) be able to be vaporized and then recreated to original form.

If we are just mass and particles, this should be possible?

Things are moving away from us at a speed proportional to their distance. The fastest objects are actually faster than the speed of light.

Its all about information. The order of atoms to make a person is information. No information passes thru the event horizon of a black hole.

So, no.

Native cryptography, I'd say

Does anyone here ever question if there's a secret space program?

Trillions of dollars of pentagon money just vanished. Whistle-blowers come forward. Patent suppression, TR-3B/Black manta sightings worldwide. But mainstream "science" and "tech", know nothing about it, right? Little bit strange.

What's stranger is how wages and standard of living (minus a few tech devices) hasn't changed much in 30 years. Air travel in 50. Anyone else think about this?

What if humans from earth are already out among the stars, and a few powerful interests just don't want to tell the rest of us, and justify it under "the public would panic" or "oil economy would crash"?
