You might do at least minimal research before calling someone wrong:

"A vatrain is a maglev train run through an evacuated tunnel." -- The Whole Internet>> ^MycroftHomlz:

You're Wrong Charlie, you get no lifetime supply of chocolate. They actually only said in the video magnets make it go up. They did not say it was a maglev train. These are entirely different animals. It is called evacuated tube because of a vacuum. Thanks for the physics lesson though.
>> ^shole:
as said in the video, the cars don't move by sucking it through a straw, but by magnetic levitation....

The tube contains a vacuum, meaning there's no air to push or pull you forward. It must use maglev propulsion as well. The lack of air allows you to go 6500km/h without burning up or causing sonic booms.

Thanks for the promote!

Comment hidden because you are ignoring dag. (show it anyway)

Pretty sure is cumulative - ie it takes more that one ...>> ^MycroftHomlz:

@dag... no "assister" bonus?

Where did I go wrong? I'll be very happy for you to set me straight. I'm no physicist!

I do understand that talking about the motion of a single photon, as if it moved linearly through space, is not accurate and not how photons behave, but I don't think I'm particularly qualified to talk about the rules of quantum electrodynamics and was just trying to correct ForgedReality's interpretation as best I could.

>> ^MycroftHomlz:

This is equally misguided, but it is closer to the correct interpretation.
>> ^offsetSammy:
This is not accurate. As far as we know, light (a photon) is massless and its speed does not change based on frequency (color).....
>> ^ForgedReality:
Light doesn't have one set speed. Each frequency of light travels at slightly different speeds.
