I've got no real physics education but I am interested in it from a popular science and layperson level. If anyone is able to help with this thought experiment. My question is, on a given microwave power setting and a fixed duration, is the heat transferred to the contents largely constant...

Gotcha. Thank you for your reply :-D

@PeroK thank you for your reply. I understand the first part of what you said but my choice of words and explanation in my opening post may not convey that. Hopefully these two points indicate this: 1) I understand that anything with mass cannot reach speed of light due to the need for infinite...

I'm just a layperson with a keen interest a couple of notches above popular science. As far as I understand SpaceTime is an attribute where if you change one attribute (space or time) then the other attribute is affected. E.g. as you approach the speed of light, the time passing of other things...

This is extremely far from being layman terms

Ah that's great and very clear. Thank you.

I'm not studying physics, I only have a keen hobbyist interest in popular science. I understand the concept of Lorentz transformation in that it is a formula to change perspective between different observers but the maths is way beyond me. If this whole question is beyond popular science level...

I'm still a bit confused. How do the observers determine the order of the events, is it based on when the light from the event reaches them? Or do they calculate how far that event was and try to work out when that light started it's travel?

Okay, so I was watching this YouTube video: Which says that there is no universal chronological order of events. Different observers may have a different order of events and both would be correct. What I wanted to try and understand (in layman terms), is this purely down to how long it takes...

In all those different places (or some you may not have mentioned), does Lithium appear #3 in any of them? E.g. did Elon say universe mistakenly when he meant crust?

Sorry, I added a YouTube link which was set to the specific time but it got converted to an embedded YouTube link which started from the beginning. Anyway, the reference is at 2 hours 59 minute mark.

I was watching a video on Elon Musk. I believe he is a smart guy and he certainly knows is stuff. However, he said something in this video which I was surprised about and I can't seem to corroborate with various Google searching. Someone asked him whether there was enough Lithium on Earth to...

Ah ok, it's as I thought. Thanks for the clarification.

I know there are many aspects of Interstellar that are true to science and it appears that there are many that aren't. I was confused about one particular aspect but wanted to know if this was actual science or one of the things that wasn't. Ok, so Earth sent some scouts to 12 or 13 possible...
