Then she transferred that matter waveform into an entirely different BEC nearby — which emitted the original light pulse.

Does this remind anyone of something??? Hmmm???

Imagine how much something like that would cost. You think plane tickets are expensive! Pretty cool.

Sorry, the "speed of light" is not and never was a constant.

What everybody considers the ultimate speed limit - C, is the speed of light IN A VACUUM. Add a medium, and all bets are off.

BTW: I posted a similar article several months ago. Cool stuff.

You are absolutely right and still wrong. The speed of light in a vacuum is a constant, and a very useful one at that.

Excuse me?!?!?! Try reading the entire post, not just the first sentence.

I said that the "speed of light " isn't a constant, the "speed of light in a vacuum" is (C is not "the speed of light" it is the "speed of light in a vacuum"). I thought I was clear when I said it. Notice I italicized and capitalized IN A VACUUM. Also, I said that adding a medium changes things.

Is English a second language? Did you read my post using a Portuguese to French phrasebook and a French/English Dictionary? Or do you just assume that you are smarter and so everyone else is wrong.

Example: I say "The sky is UP in my frame of reference." Your reply, "Wrong, the SKY is up in your frame of reference."

Guess you put me in my place.

sry, steel, downvoted due inflammatory nature of your post.
It was hard, because you are technically right.

Seems like to me that it was just a simple misunderstanding.
