Soviet Union dissolved 30 years ago, but it sure feels QAnon is going strong. As your first ever post to,this community, you really should’ve tried harder. YouTube isn’t a good source, but at least link to a specific video when mentioning it. You may as well be saying “I understand from google search engine that…”

Another piece of the puzzle of life. Seems to present very primitive form of cell differentiation, with only two types of cells. A billion year old fossil, which provides a new link in the evolution of animals, has been discovered in Torridon, Scotland. https://phys.org/news/2021-04-billion-year-old-fossil-reveals-link-evolution.html The organism was spherical in shape, suggesting also that cellular differentiation, "tissue" formation, and body plan were very primitive. https://www.cell.com/current-biology/fulltext/S0960-9822(21)00424-3

This is a science site. A majority of the active members have scientific educations, or an extensive interest in science. As such I should be greatly surprised if many of them, perhaps not any of them, failed to accept evolutionary theory, as developed from the original Darwin-Wallace concept, as being the best explanation of the diversity of life on the planet. So evolution is a given, on this forum and in this thread. What this thread is actually about is substantive evidence for an important stage in the evolution of more complex organisms. Empty prattles about personal incredulity have no relevance. Edit: Cross posted with @swansont's mod comment.

An observer will see the beams separate at 2c. You can’t analyze this from the perspective of either light beam, since that does not represent a valid inertial frame if reference If these were objects traveling at an attainable speed (i.e. less than c), then you can do this with the velocity addition formula. Let’s say they move at u and v relative to the central frame (of the person tossing the objects). They will see the total distance between them increase at (u+v) (using scalar speeds) Each object will see the other recede at (u+v)/(1+uv/c^2) http://hyperphysics.phy-astr.gsu.edu/hbase/Relativ/einvel2.html#c2

There are two Republicans that are up for sexual exploitation of minors right now...

As was this entire post. Don’t comment if you don’t care, and at least try to offer something even vaguely relevant when you do.

It is not strictly true that water is non-compressible. Liquids are about as compressible as solids, which is to say hardly at all by comparison with gases. But they still compress a bit. If you suddenly expose the water in a torpedo tube to 100atm, you exert that pressure on the water inside and thus on the walls of the tube as well. The water will compress a tiny bit and the walls of the tube will stretch and expand a tiny bit as well. (Because it is only a tiny bit, very little work is done, so there will be very little stored energy in the compressed and stretched materials.) Water hammer is a shockwave caused by abruptly blocking the path of a moving mass of water, thereby causing rapid change in momentum. This change of momentum requires a certain impulse (F x t) and because t is so small (because it happens fast), F has to be great. So that means water hammer creates large forces and hence pressures - a pressure wave. When you open a torpedo tube that is full of water, you do not have this, because the water on both sides of the opening is static and no change of momentum occurs. So it won't cause water hammer, just a bit of stretching of the walls of the tube. As for the equalising valve, I suspect that will be because when you flood a torpedo tube in practice you most certainly do have trapped air, which will compress to 1% of its volume, storing a lot of energy and causing water to flood in as it is compressed - with momentum. So there can be large forces and energies created in that scenario, which you do not want for safety reasons. So you flood it progressively rather than instantaneously. At least, that would be my best guess as to what is going on.

Each GPU core contains 128 Arithmetic Logic Units, ALUs, for a total of 1024 ALUs. Fabbed by TSMC in a 5 nm process, they have 4 hi-performance CPU cores, and 4 lo-performance CPU cores, for a ( claimed ) world's best CPU performance per watt.

Oh wise one, since you speak for everybody, let me tell you and yours, everybody thinks you speak for nobody. This is a digression from the OP. Humans are humans, apes are apes. But since you refuse to accept this I suggest you mate with a female ape and the offspring will end this debate once and for all. agree?

I had once understood from a YouTube video that in the Soviet Union only the most serious criminals were sent to prison camps, including pedophiles (Note: Pedophile does not have to mean child molester)! This gives me a strange feeling, because I always thought that left-wing people and communist people in particular cared more about accepting other people. Of course the YouTube video with pedophiles could only have meant child abusers, but what I have also believed is that the acceptance of pedosexuality belongs to the left and NOT to the right conservatives!
