WARNING: Sabine waves around some delicious-looking chocolate cookies for the whole video which may give you an irresistible urge to eat some afterwards resulting in you raiding your stash of them, or rushing out to buy an emergency supply if you don't have any and then stuffing your face with them, all of them. You have been warned...
I remember learning that while general relativity shows that matter cannot accelerate to faster than light as it would require infinite energy, it doesn't forbid something travelling FTL if it's already FTL. That's where the hypothetical tachyons come in. I might not have it exactly right, but it does go something like that.
Following on from that, respected physicist and YouTuber Sabine Hossenfelder explains why light isn't an absolute limit and claims that the general physicist community is wrong to say it is. What she says is pretty controversial, but that doesn't make it necessarily wrong. There are many instances in history where one person has gone against the established scientific view about something, were heavily criticised for it, but were ultimately proved to be right, so this might also be the case with Sabine.
As a regular guy, I couldn't follow all of it and I don't have the deep physics knowledge needed to counter what she's saying, so I'm keeping an open mind, suggest that you watch it, see what you think and post your thoughts below. Darn those cookies...
