Can we tell if there's a wormhole in the Milky Way?

This is a brief comment on an article by Dennis Overbye that recently appeared in the New York Times

This article is about a paper which got recently published

It's openly accessible on the arXiv here

I explain in this video why wormholes are not a prediction of general relativity that is even remotely comparable to the prediction of black holes or the expanding universe or gravitational waves. The existence of wormholes is pure speculation. In fact, if we trust our theories, then we have more reason to think they do not exist than they do exist.

I further explain why studying the consequences of mathematical fiction like this is not a promising scientific route to progress.

Loved the analogy with "invented diseases". Bang on.

I like the Fermilab channel to get some basic physics, I like PBS Space Time to explore what might be possible. But I love Sabine's channel because she keeps us honest and grounded in reality.

"Sound ridiculous? Yeah, it is ridiculous."
*_SAVAGE!!!_* 😆

I liked the way you dropped the solutions to Einstein's field equations book on the table.
And all the rest as well.

Hosenfelder took no prisoners on this video.

"sounds ridiculous? yeah, it is ridiculous" 🤣🤣 love it... keep up the good work

[kodi]

your stringent way to argue combined with your dry humor is both compelling and entertaining, love it!

Too many science videos are full of sensational click bait. I very much enjoy this no BS approach to delivering information. Thanks!

Interesting and worthwhile video. If we measured some variances in proximity to our galaxy's supermassive black hole, by Occam's Razor, there would likely be a simpler and more plausible explanation.

Dr. Hossenfelder, your viewers (myself included) would be immensely happy to see you on Sean Carroll's "MindScape" podcast.

Thank you Dr.Sabine for bringing forward this video. It is a general misconception which I also find among the youngsters who are more fascinated by speculations of science like wormholes and time travel but they hardly realize that they are just equations and cannot exist in reality. I would also request you to bring forward a small lecture of your's on what is meant by "solution" to Einstein's field equations and that black holes and singularity are actually solutions which need to be satisfied under special conditions.

There is also a misconception on what leads to black holes....

Thank you very much.

Thank you for this video.
It is so important to remind modern scientists that science is about empirical observation.
If doing science starts with opening a book or booting up a computer, then it is not science. All science starts with observation or an experiment.

THANK 👏🏻 YOU 👏🏻 FOR 👏🏻 SAYING 👏🏻THIS ! 👏🏻

[davidmccormick]

Brilliant your comments on mythical diseases was superb. Keep these videos coming you are doing a great job

[racingfortheson]

You are one of my favorite scientist EVER!!!

[lisamangles]

Economy of words... clarity of thought.. a wonderful gift..a delight to watch your video's!

[hrperformance]

I feel like the wisdom I am gaining from this lady is going to be invaluable in becoming a good physicist. I will do my absolute best to apply these fantastically presented lessons!

[zamori]

Thank you Sabine please keep up the good job defending science we have a lot of Charltons . from your Algerian fan .

[zakolia]

Now WHO ARE YOU?
answer: My new favorite science speaker!
That was satisfying in the field. I'm subscribing without hesitation. Looking forward to listen carefully to whatever you have to say.
At last, a scientific truth seeker that's not hiding behind theroricists.

This and more why I admire Prof. Sabine than the other physicists. Her treatment is careful and try to avoid the elaboration of speculation like other physicists like neil, michiko, and the late hawking.
