The Holographic Universe Explained

↓ More info below ↓

We live in a universe with 3 dimensions of space and one of time. Up, down, left, right, forward, back, past, future. 3+1 dimensions. Or so our primitive Pleistocene-evolved brains find it useful to believe. And we cling to this intuition, even as physics shows us that this view of reality may be only a very narrow perception. One of the most startling possibilities is that our 3+1 dimensional universe may better described as resulting from a spacetime one dimension lower – like a hologram projected from a surface infinitely far away.

The holographic principle emerged from many subtle clues – clues discovered over decades of theoretical exploration of the universe. Over the past several months on Space Time, we’ve seen those close clues, and we’ve built a the foundations needed to glimpse the true meaning of the holographic principle. We’ve moved from quantum field theory to black hole thermodynamics to string theory. We’ve made a background playlist if you want to start from scratch, and I especially recommend catching last week’s episode. But this is tough material, so let’s do a review.

The only part of the video that i understand is when he tried to sell merch.

[tinunit]

This video proved I'm dumb in every dimension.

[MJR]

2-D surface that appears to the observer as 3-D. For God’s sake don’t let the flat earthers see this.

[Casey]

‘Wait, what’ *rewinds*

3 seconds later. ‘Wait, what’ *rewinds*

[mLify]

"Over the past few months on Space Time ... we've built the foundations needed to glimpse the true meaning of the holographic principle."
Me tuning in to this video randomly: Oh shit, I just walked in to the final without ever going to class... 😰😨😰

[nafrost]

It’s amazing what we can do with the same brains we used to throw stones at each other.

[scobra]

If you didn't get any of this, you're still a human being.

[bradyvelvet]

One of these days Matt will troll us with something totally fictitious and we won’t even know it 😂😂😂

[TheExoplanetsChannel]

New PBS Space video + First image of a Black Hole = Best day of the year.

[olot]

So begins the war between flat-earthers and flat-universers

[nikanj]

When you feel completely on top of a lecture and go to the bathroom and somehow come back two semesters behind.

[TrebleWing]

There is something very reassuring about not following 99.999% of this. Just knowing that someone out there understands this, and is in fact advancing this sort of math/research means there are still people out there that are passionate and talented enough to tackle the universe.

[radrook]

Well, at least he SEEMS to understand what he is talking about.

[GiveMeFive-GMF]

English has never felt more like a foregin language to me than when watching this video.

[TheCarnivalguy]

He lost me after he said “We live in a universe...”

[IAmNumber]

Wow this channel makes me feel like a damn caveman

[lyndensmall]

Who ever did the music and animations of this episode deserves a raise

[SuperLusername]

Its like...I know the words you're saying, but I dont understand the sentences

[jonforpresident]

Came here to find out how dumb I was. I have my answer. I am very very dumb.

[turner_kc]

i was so confused and then the bananas brought me back.
