Comments by "Lepi Doptera" (@lepidoptera9337) on "I Think Faster Than Light Travel is Possible. Here's Why." video.
Why are you telling is that you failed science class, though? ;-)

Yes, but all that crap makes us slower, not faster. :-)

All of her videos are like that. ;-)

You are welcome to show us how. ;-)

Trillions of aliens what you to hold their beers. ;-)

Then we would be using a radio. Radio was invented some 130 year ago or so. :-)

Relativity. ;-)

@kevin9218 Relativity doesn't suggest that wormholes, even if they should exist, are traversable. It does suggest that they can't exist, though, because they are not stable solutions. All suggestions of "warp drives" assume that we have copious amounts of matter with negative mass or negative energy at our disposal. Since the latter doesn't exist, these suggestions are basically just very complicated mathematical proofs that FTL travel is impossible, even in the GR scenario.

It doesn't "happen" at all. You need to go back to the learning unit about "correlation is not causation" that you missed out on.

You didn't take enough muscle supplements. Your arm is too weak. ;-)

Why are you projecting your failure to learn science? ;-)

Congrats, you have told us in oh so many words that "time is that which the clocks show". We teach that to kids when they are five years old. ;-)

@bnielsen56 Well, those of us who have studied physics know that c is a dimensional constant and therefor its absolute value is meaningless. We usually set it to 1 in rational unit systems. It has therefor absolutely nothing to do with electric and magnetic properties. It's the maximum velocity with which energy (in any form) and causality can spread. I don't know what bubble you are talking about. There are no bubbles in this universe. That's just bad theory pretending to be physics. You can just laugh about it, invoke a chant about time traveling intelligent perpetual motion machines and then move on. ;-)

@bnielsen56 The source of the CMB is a thermalized plasma with a bit of an acoustic rumble in it. We have, as far as I know, no indication that the physics at that time was significantly different from the physics we have today. Inflation would have been way before the decoupling of matter and radiation and I am not a strong supporter of it. I don't think it solves any problems that need urgent solving and even if it does, it does it in a completely useless way by introducing infinite degrees of freedom. What it certainly does not do is to introduce local FTL. Physics majors don't work on things like the CMB and inflation. That's for PhDs, kid. At least try to sort out who you want to be jealous of before you are making foolish emotional comments on the internet. :-)

It takes only a dozen lines of high school algebra to show that you are wrong. ;-)
