Do you believe the Earth is flat or round?

Here is something to think about als i looked this up .

Question: What is the Many Worlds Interpretation of Quantum Physics?
I've heard of the many worlds interpretation (MWI) of quantum physics. What is the many worlds interpretation? Do all physicists use it? What's the difference between it and other interpretations of quantum physics?
Answer: The many worlds interpretation (MWI) is a theory within quantum physics intended to explain the fact that the universe contains some non-deterministic events, but the theory itself intends to be fully deterministic. In this interpretation, every time a "random" event takes place, the universe splits between the various options available. Each separate version of the universe contains a different outcome of that event. Instead of one continuous timeline, the universe under the many worlds interpretation looks more like a series of branches splitting off of a tree limb.
For example, quantum theory indicates the probability that an individual atom of a radioactive element will decay, but there i
If you had a bunch of atoms of radioactive elements that have a 50% chance of decaying within an hour, then in an hour 50% of those atoms would be decayed. But the theory tells nothing precisely about when a given atom will decay.
According to traditional quantum theory (the Copenhagen interpretation), until the measurement is made for a given atom there is no way to tell whether it will have decayed or not. In fact, according to quantum physics, you have to treat the atomas if it is in a superposition of states - both decayed and not decayed. This culminates in the famous Schroedinger's cat thought experiment, which shows the logical contradictions in trying to apply the Schroedinger wavefunction literally.
The many worlds interpretation takes this result and applies it literally, the form of the Everett Postulate:

there are people out there who still believe the earth is flat?
(i think it's round, obviously)

If the earth was flat we would be able to find the end of the world. We would have to go on the other side of the world... but clearly when we walk... I could walk forwards now and go around the world and would end up at the place I started.
We have also went to space and seen earth for itself, it was 100% round from very far away with of course a less round shape up very close (due to mountains) it is more of a spiky ball (mountains, hills etc. Earth is not completely smooth) but it is 100% round.

What a question! I just had my 4 year old nephew over this evening and amongst the rest of the stuff we did, he spent a while with a little globe of the earth, asking me questions about different countries, why they're this specific colour on the map, etc etc. Then he opened a toy shop and expected me to buy my globe from him for "21st dollars please!" Which was discounted to $5 after I pointed out I had no money and his price was too much for me to spend even invisible money on..
Anyway. He's been clear on what shape planet Earth is for a couple years now, and happily tells anyone who'll listen about (his understanding of) earth's atmosphere, gravity, and how come we can jump but not fly or float away. He's a clever child and I adore him, but he's not off-the-charts in terms of his knowledge and understanding of the world around him. He's just encouraged to seek answers to all the normal questions children have.
As an early childhood educator I've used a simple yet effective experiment for years and years with children 3+ years of age who are curious about how the earth can be round, yet it looks and feels more or less flat. Get a yoga ball, the bigger the better but actually any sized ball big enough to hold a map (any size, scale is not crucial) taped to it will work. If the ball is big enough for a child to lay on, then have them do so after showing them how to roll it along with their knees/feet/hands/whatever works whilst balancing their head as close to the "edge" of the ball as possible. If not, create a similar effect by them rolling it along with their chin resting on it. This is excellent for gross motor and many other aspects of development, anyway, but allows them to look at the ball as it rotates and see how it flattens out in terms of how it looks - despite not changing it's shape (much). This is a great way of exploring horizons and introduce real-life "optical illusions" and is just plain fun as well! This experience is usually followed by weeks of experimenting with this as well as torches and balls to cast shadows and reflections and generally exploring light and different shapes in the environment.
The most common observation from a child I hear when someone (almost always a parent/random relative thereof) "jokingly" mentions the earth is flat is : "no it's not! The map is flat, but if you roll it around, it's fine!" ... and then I step in and fill in the details.

Um lmao what kinda question is this??
If the Earth was round, all the water would fall off, and the planet would like...roll around a lot LMAO

I voted for round. I don't think Earth is flat.
