Is Time Real?

Correction: The photo at about 1 mins doesn't show Hermann Minkowski (who is the one I meant) but his brother Oskar. Sorry about that.

In this video I explain why some physicists argue that time does not exist, and what that even means.

Time is actually a function of the number of comments a youtube video has

Time and space are relative. The more time I spend with my relatives the more space I need

All day long I've been asking people what time it is and they keep giving me different answers.

Love this. I may not watch with complete understanding, but I always watch with intense interest.

I’ve never heard time explained like this before, this was a wonderful video. That definition makes so much sense, really interesting topic.

I come here mostly to hear her say "Einstein".

Dr. Hossenfelder, I've watched several videos about this subject and yours was by far more understandable than the others!!!!
Thank you.

I really enjoy watching Sabine's videos about complicated stuff. I keep thinking about them after and realizing I don't know enough about the basics to absorb even half of what she said. That's when I get watch other videos about the subject and then come back to rewatch the video and enjoy it even more the second time.

Love your content, delivery, thoughtfulness, and, humor! Thank you Sabine

boss: 'you're late again!'

me: 'is time even real?'

[BabyDespair]

I never get tired of Sabine's explanations

[SkyIsTheLimit]

I like her style. Easy to follow. Her English is actually excellent, considering that it's not her first language. I have high respect for Sabine. Please keep making these video.

[ronconner]

Wonderful video. Liked how you avoid unnecessarily long explanations. Time as an emergent concept is really thought provoking.

[BalancedBlackwood]

I love your subtitle of “Science with out the gobbledygook”! I love watching your videos, especially because I am not good at math and yet I still very much understand you explanations. Thank you for your knowledge. 🙏

My favorite YouTuber, by far. My mind is edified and blown every single time.

Been studying non-duality. My experience is that it is always now. I cannot move out of the now and into the future (or the past.) Time is a concept, an incredibly useful one, but show me how there is anything but now.
