Faster-than-Light Travel May be Possible After All, BUT . . .

http://backreaction.blogspot.com/2020/05/is-faster-than-light-travel-possible.html

The link above is to a blog run by Dr, Sabine Hossenfelder.

Hossenfelder points out that we have no engineering basis for traveling faster than light, but that Einstein's equations do not forbid it.

We should also consider that very advanced technological civilizations on distant planets, may have mastered laws of nature which we do not know exist.

Also, to travel from one place to another need not require moving from point a, to b, to c, etc.  Jumps across intervening distances without occupying the intermediate points, while entirely speculative, are not ruled out in principle.  Quantum entanglement suggests a possible foundation for such an idea.

A few people with whom I have discussed this are very quick to brush aside Hossenfelder's comments, in some cases without having actually read them.  That indicates a level of bias and closed mindedness that is incompatible with scientific inquiry.

Hossenfelder has a Bachelor's degree in mathematics and a PhD in physics. She graduated at Frankfurt University, Germany.  She is a research fellow at the Frankfurt Institute for Advanced Studies.

This does not necessarily mean that she is right, but only that she is worth hearing out.
