Ted Watson has been banned as a sockpuppet of mpc755 et al.

prashant akerkar and prashantakerkar have been banned. One for sockpuppetry, and since a second account was used to circumvent the mod queue, the other has been banned as well. David Hine's vacation has been extended indefinitely.

No, not so much. If the theory predicts a clock will show a certain amount of elapsed time in an experiment, or the frequency will shift a certain amount, and that's what you measure, there's not a lot of room for "interpretation" Argument from personal incredulity is about as effective as a nerf® vibrator.

Fortunately, your comprehension is not the metric we use. Does a spherical or cylindrical coordinate system curve? GR uses non-Euclidean geometry. It is what describes spacetime, and it is curved. No. What makes it true is that experiment agrees with the theory.

! Moderator Note No, that's not going to happen. Big Bang is mainstream physics and discussion of it and the lines of evidence that support it can and should be discussed in the science sections. And you should stop hijacking discussions to air your dissatisfaction with the situation.

SamCogar has been suspended 3 days for repeatedly going anywhere and everywhere but on-topic.

! Moderator Note If you wish to discuss this, start up a thread in the speculations forum. Be sure to bring more evidence and detail than you have presented here. In this thread, it's hijacking. edit: since you've hijacked another thread, it has been split.

P = E/c only applies to massless particles

Nyuck, nyuck, nyuck!

Ant Sinclair has been suspended three days for personal attacks and thread hijacking

Vvi has been suspended for abusing the PM system

Threads that end up in the trash are effectively locked; no further posting is allowed. This will happen for a variety of reasons. One common one is hijacking, where the hijacker has violated other rules (or has used up their goodwill) and the thread is not simply split off. (A warning point might accompany such an action, or it may be the last unofficial warning for repeated hijacks) If that's the case, this does not preclude other members from raising that topic of discussion in a new thread. If a thread has been trashed because it's clearly unscientific or otherwise nonsensical, then it should not be resurrected. We trust your judgement in this.

That's smaller than the dimensions of the ISS, which is > 100m long

You would want the entryway to be moving slowly, so let's say that's one complete revolution every 12 seconds, or around a half a radian per second. Your central axis is 2m in diameter, so r is 1m. That means the ladder you need to grab is moving 0.5 m/s. That's probably the fastest rotation you can comfortably have. To get 1g at that rotation, the radius needs to be almost 40m long. The outer rim is moving 20 m/s, but you have your ~38 meter climb to transition to that speed.

Not being a complete wheel isn't the issue. You take up almost 2m of space with a person standing somewhere with their feet at the center of the space station. Their bed is a little more than a meter away, and is moving >20 km/hr. You're going to injure yourself as you leap into bed and try to grab on to something, or when you get out and try to come to a stop. It must be a much larger radius for this to be feasible. You need to be able to e.g. climb up a ladder to transition to the faster speeds

But as I showed, a small centrifuge has challenges. Your bed is going by you at >20 km/hr when you are at the axis. How do you get in and out? I would think a larger radius, to mitigate that problem and also use it for an exercise area rather than sleep.

Stevie Wonder has been banned as a sockpuppet of Mikemikev (and Sammy Boy, and probably also Over 9000 and Dave Davidson)

A little over a 3 meter radius then. a = v^2/r You need a speed approaching 6 m/s to get 1g. Have fun getting into and out of bed.

I assume you are suggesting something like the setup for the spaceship in The Martian. How big would the ring need to be, under reasonable assumptions of rotational speed?
