- IBM just unveiled their 2nm data processing chip. Quantum effects start operating in the 5nm range, how is it possible to bypass these effects?
- Has anything ever gained 5 sigma and later been proven wrong?
- Why does the Chinese rocket have an oscillating path instead of a straight path as it falls down to earth?
- Do cetaceans spread respiratory diseases between each other?
- Since the moon has no atmosphere to induce drag, can an object theoretically orbit at say, 1 meter above the highest landform on the surface if the velocity is correct? Would this orbit be stable? If so, what's the velocity?
- Can spark plugs produce X-ray emissions?
- Does wearing black clothes make a big difference in terms of heat perceived as opposed to wearing white clothes in a hot country?

| Has anything ever gained 5 sigma and later been proven wrong? Posted: 08 May 2021 11:03 PM PDT As written. Has there ever been a scientific discovery that has gained 5 sigma but has later been disproven? If not, what is the highest something has reached and then been wrong? [link] [comments]  |
| Posted: 08 May 2021 12:50 PM PDT I think its due to the earth's rotation, but I don't understand why that would have anything to do with the satellite having an oscillating orbit. [link] [comments]  |
| Do cetaceans spread respiratory diseases between each other? Posted: 08 May 2021 08:50 PM PDT Clearly such a big problem for humans, but since marine mammals breath so differently, it made me wonder. [link] [comments]  |

| Can spark plugs produce X-ray emissions? Posted: 08 May 2021 06:08 PM PDT After learning how an X-ray tube worked, it struck me as similar to a spark plug from a car, as both have a large voltage potential between an anode and a cathode. Could a spark plug placed in a vacuum produce X-ray emissions in a similar way to an x-ray tube? [link] [comments]  |
| Posted: 08 May 2021 10:02 AM PDT My really basic understanding of this field of physics tells me that white reflects the light spectrum while black absorbs it so my naive assumption would be that wearing white clothes should help tolerate hot weather better. But how big is the difference in actual heat that wearing white clothes helps reflect? Hope my question makes sense [link] [comments]  |
| Why does most space junk land in the Pacific Ocean? Posted: 08 May 2021 03:25 PM PDT I could assume probability increases with larger surface area. However I read that space junk rarely hits land. Why is that? Is there a reason that the Pacific Ocean attacks space junk? Could it be magnetic pull? [link] [comments]  |
