Black holes bend spacetime so much that direction called "the future" is pointed towards the centre of the black hole itself.

Light cannot fight the flow of time and it just so happens that the flow of time in black hole is hell bent on keeping you there. One cannot escape a black hole anymore than one can escape to the past.

The Colosseum has been under control of many different people and used for many different purposes. Each change resulted in modifications (ie the wooden seats were all removed to be used as barricades when people started using it as a fortress instead of a stadium).

A lot of the building has fallen down due to earth quakes. Some of which are quite recent. There's markers around the outside that show where the REAL outer walls should be. It used to be a lot bigger.

What does peaceful protest even mean at this point? Destroying historic monuments? Blocking ambulances? Defacing unrelated paintings? Looting stores?

Using an important issue as an excuse to disrobe yourself of any and all social and cultural limitations just seems so dishonest.

> I'm raising awareness of climate change!

Who's awareness are you raising. Climate change hasn't been a controversial issue for the general public in this country for at least a decade, if not longer.

> I'm sticking it to the government/police/bankers!

By invading art museums and blocking commuters? If you want to send a message to those in power, then go to the places that those people reside. Don't lash out at people that are completely unrelated to your frustration.

The merit and value of peaceful protest is being eroded by these pseudo-protests. What happened to boycotts and hunger strikes and chanting outside of parliament? How did we get this point where peaceful protesting is just code for "try to get arrested while holding a banner".

Does medium have some extra criteria I'm not aware of?

In short: yes.

Because the dice doesn't remember what's happened in the past. It's an inanimate object that doesn't undergo any significant change after being rolled.

Can you imagine if the opposite was true? If dice remembered the past and tried to correct for it? How would you know if you're holding a normal dice or dice that (unbeknownst to you) has recently rolled 6 100 times and is now determined to roll something different?

You're being down voted for answering an ELI5 on a topic you know zilch about.

And I'm not sure why you're replying to my comment with this sarcasm after I genuinely engaged with your comment and explained what you were pondering

You can make tic tac toe as many dimensions as you'd like. It's easy enough to do on paper. 4D tic tac toe is only 27 squares. 5D is an overwhelming 81, but there's nothing stopping you from drawing 81 squares on a piece of paper.

The issue is that tic tac toe becomes a worse game the more dimensions that you add. The entire point of the game (if there even is a point) is to block the other person from winning.

The more directions that lines can point in the more pointless it becomes to try and block your opponent.

Dimension is a broad mathematical term, that very loosely means "ingredient".

The numbers that you are used to 1,2,3,4 etc have one ingredient. That ingredient being "1". We call these "1 Dimensional". Such numbers are ussually useful, but sometimes they are not able to capture the reality of a situation.

You can count cookies with 1D numbers, but when you want to describe WHERE you are, you need three ingredients (UP, RIGHT and FORWARD). Hence we live in a "3D world".

You might use more complicated numbers to describe your situation in more detail. Perhaps you want to know where you are but also how hot it is, which would require 4 ingredients (4 dimensions).

Physicists generally are often interested in WHERE and WHEN, because they are specifically interested in movement. The physics of a situation that doesn't change does not require a professional after all. Hence, (for their purposes), 4 ingredients are needed to describe a situation.

Sometimes physicists will use 6 ingredients: 3 for where (position) and 3 for where will you be (velocity).

Sometimes they are interested in a situation where some ingredients don't matter. In simple harmonic motion, there is a simple repetition, so only one ingredient is needed to describe the where and another for when.

By changing which number systems are used for the mathematics, we can make calculations easier or clearer or link two problems that seem unrelated at first.

Sci fi have often (incorrectly) used the word dimension as a stand in for "universe" or "world". And this has led many snake oil salesman to making videos that claim the "fourth dimension" or "fifth dimension" to be some mystical hidden place.

Dimensions don't have an order so calling anything the 4th dimension is misleading in and of itself, never mind the weird pseudo science that the term is used to push.

Cake could be said to be 3 dimensional. Any basic cake is some combination of flour, egg and milk and so we could label each cake with a 3D number and discuss which 3D numbers correspond to nice cakes and which correspond to failed cakes. For example (0,0,1), or a cake containing only milk, would be a failed cake.

If I then came along and showed you a chocolate cake, suddenly I'm adding a "fourth ingredient": chocolate. But there's nothing mystical about chocolate and it's only "4th" in the sense that you weren't considering it beforehand and now you are.

If you've had 14 therapists, surely you have some idea of what you want from a therapist?

Personally, I think therapy is something that most people simply won't get much out of. I think that's a reasonable position to take. But if that's how you feel, then why spend money on therapists?

ANYONE can declare something. It's just a matter of how much stock you put in the declaration.
