MMike_bb reacted to A.T.'s post in the thread High School I don't understand the Michelson–Morley experiment with
Like.
If you build the ruler in flat space (far away from any masses), and then near the mass you support it, such that it doesn't deform... -
MMike_bb reacted to PeroK's post in the thread Undergrad Does Time Dilation mean we are each alone in our own bubble? with
Haha.
If you find yourself alone on a Saturday night, you cannot blame the laws of physics. -
MMike_bb reacted to Sagittarius A-Star's post in the thread High School Einstein equations don't work at large scale? with
Agree.
100% of engineering & technology use Einsteinean physics, but in > 99% of the use cases Newtons laws of classical mechanics are accurate... -
MMike_bb reacted to Dale's post in the thread High School Einstein equations don't work at large scale? with Agree.
Yes, and we also have lots of evidence validating Newton’s laws. We can’t wish that away either. The existence of that evidence is why...

MMike_bb reacted to PeterDonis's post in the thread High School Einstein equations don't work at large scale? with Agree.
Not "wrong", no. It is a valid approximation to GR in the regime where gravity is weak and all relative speeds are small compared to the...

MMike_bb reacted to robphy's post in the thread Undergrad Comparing the time of two moving clocks with
Informative.
(For historical purposes, it’s good to note that this thread is preceded by (in reverse chronological order) on SE: How can a clock... -
MMike_bb reacted to pervect's post in the thread Undergrad Comparing the time of two moving clocks with Like.
There's a paper that suggest an approach to explaining this problem using space-time diagrams. I like the approach a lot, but I haven't...

MMike_bb reacted to Herman Trivilino's post in the thread Undergrad Comparing the time of two moving clocks with Agree.
E2 and E3 are different events. Of course the clock readings are different. Would you expect leaving for home and arriving at an event...

MMike_bb reacted to Sagittarius A-Star's post in the thread Undergrad Comparing the time of two moving clocks with Informative.
That's not correct. Each rocket sees the relativistic Doppler effect. The formula for it can be written as a product of the...

MMike_bb reacted to PeterDonis's post in the thread Undergrad Comparing the time of two moving clocks with Like.
No, this is not correct as a description of what each observer actually sees--the timing of the light signals they receive. If the two...

MMike_bb reacted to kuruman's post in the thread Undergrad Comparing the time of two moving clocks with Informative.
Observers at separate locations moving relative to each other just can't look at each other's clock and decide whether they run slow or...

MMike_bb reacted to Nugatory's post in the thread Undergrad Comparing the time of two moving clocks with Like.
This is wrong, and we can try one more time to explain why Using the frame in which A is at rest, events E1 and E2 are simultaneous -...

Strong suggestions: The position-vs-time graph of a situation (also known as a spacetime diagram) [like the ones I have been drawing]...

MMike_bb replied to the thread Undergrad Comparing the time of two moving clocks.Thanks to all! I catch an insight and now I understand how reciprocal time dilation works!
