I'm also going to challenge the idea that the mammoth looks like it's at a disadvantage. Those tusks have much further reach than the T-Rex's mouth. Knowing how most predators operate, I'd put my money on it passing on the risks associated with attacking a healthy adult nine times out of ten

There is a difference between being able to simulate something, and being able to perfectly predict a specific outcome. I can simulate a dice roll. That doesn't mean I'm going to win at craps.

Sorry, French is too complex. I prefer the simplicity and ease of understanding that comes from using English.

Which is essentially what I said...

This is what I get for not clicking links.

Mythbusters did this firing a basketball out of an air cannon off the back of a truck (I believe that was the set up). It took them a lot of tries to perfectly match the speed of the truck to the speed of the ball coming out of the cannon, but eventually they did manage to get the ball to just drop and bounce straight up and down.

You know who says that?

And this is really where the problem lies. There are areas where we didn't evolve constraints or proper feedback mechanism because we already had them imposed on us by nature. No major reason for there to be a "stop storing fat, you're big enough already" switch when nobody ever had enough food for the health problems to become more of an issue than starvation.

And the "natural" delay can be extended by time dilation in the same way that it can be extended by distance. I'm really not sure what more you're looking for.

This is not the place to ask people to do your homework for you.

A thousand light year larger person would see their arm touching things long before they felt them even without time dilation coming into play because light travels much, much faster than nerve impulses. Over very small distances (like the length of your arm) the difference in arrival time is negligible to the point of being undetectable to your brain. Over very long differences, the amount of time that your nerve impulses would lag behind the light accumulates and would become very noticeable in short order. Time dilation could, in principle, create a similar effect to distance in this case. If you have a signal moving at light speed racing a signal racing at nerve speed out of an extreme gravity well, time dilation could increase the amount of lag between when you receive the light speed signal versus the nerve speed signal as compared with the same distance traveled without the gravity well.

My confusion is over why that scenario needs avoiding. Why would there be any reason for that to happen in the first place?

I think the fat/skinny swap is a good availability thing. Just like a tan used to be the result of labor ing outdoors, and pale skin a sign that you could afford not to, being a... healthy weight was a sign that you could afford to eat well. Now, especially in the West, indoor work has become much more widespread, so a pale complexion has become a sign that you spend a lot more time working while a "healthy" tan shows that you can afford to spend time outside, presumably not in the office working. Similarly, food has now become ubiquitous and cheap. Most people cat afford enough food to keep from starving, so carrying some extra weight is no longer a sign of wealth. Instead, it's people who can display a fit body that demonstrate the wealth necessary to expend the time and money on healthy food/gym membership/personal trainer. It's all attraction to indicators of success. Those change over time with societal and cultural circumstances.

Why would you pass through an object just because the signal telling you you've touched it hasn't reached your brain yet?

It takes time for the signal to travel through your nervous system to teach your brain and experience a sense of touch. The speed it takes is significantly less than the speed of light, so however long it takes like to reach you from the point of touch, the sensation is going to come after. You won't feel whatever you're touching before the light reaches your eye.

Short of a black hole, I can't think of any gravity well that is going to completely "contain" an explosion. Your question isn't well formed.

Is a water balloon a solid or a liquid?

If there is a strong selection pressure and only one (easy) path to a flagella, then any situation where the flagella evolves is likely to be the result of the same mutations. These mutations, given enough time, will occur anyway, but without the selection pressure, they are exceedingly unlikely to be retained and lead to widespread reemergence of a flagella structure. Under the selection pressure, the newly reformed flagella is likely to propagate very quickly. It's less a mark able coincidence and more that it's a fairly simple mutation and the only such mutation that is likely to lead to the reemergence of a highly favorable trait. Given enough time, you would reasonably expect most any population under a strong selection pressure for that trait to wind up having that mutation be widespread.

I'm just going to leave this here:

It's a real thing that doesn't mean what most people who make posts about it in the Speculations forum think it means.

It's because Andromeda is a galaxy.

I would be amazed to learn that our sun was in a binary system with Andromeda.

Two points: First, most of the people here aren't teachers. Second, and I'm not trying to be mean, but the holes in your vocabulary make most of your questions sound a bit like "What can I find purple monkey dishwasher?" And that is exceedingly hard to answer. No one here is trying to pick on what you said just for the sake of picking on you. They're trying to figure out what it is that you're actually trying to ask so that they can point you in the right direction.

Out of curiosity, I just took out my phone and was able to easily reproduce the "I can see the shoulder and forearm but not the upper arm" look from the photo myself within a matter of seconds.

Yes. But I was responding to a post about instantaneous teleportation, which you can't do. The problem with this that I was attempting to illustrate, is that the whole concept of leaving one point and arriving at some distant place "at the same moment" has serious problems. When exactly is the same moment? Because of relativity of simultaneity, co-located observers in different frames me see a different moment at a distant location as being simultaneous to their own. In reality, this doesn't matter because the math in relativity works itself out so that everyone agrees on causal events, but if you're throwing out the restriction on travel time, then what I consider traveling from one point to another instantly might be traveling into the past as seen by someone else. You can't do that in real life, of course, because relativity makes this scenario impossible, as you said.
