Rigorous Science Which of these changes to physics will have the least effect on Earth's biology?

The Solar System has entered a region of space where the laws of nature are slightly different. It will experience different physics for 3 years, then things will return to what we know now. Which...

Rigorous Science What is the yield of a 1kg solid concrete transporter bomb?

I want to beam into solid concrete as a bomb. I have transporters and unlike Star Trek I'm not afraid to use them. Terrorists have taken the tech and have nasty plans for us. The bomb is 1 kg sphe...

Q&A What evidence would there be if radioactive decay changed 7,000 years ago?

I know we generally operate - or religiously operate - on the principle that fundamental things don't change over time. It's the bedrock of geology - Uniformitarianism. I also believe it is unprova...

Q&A What star can give an earth-like planet a 1-day year?

I did the orbital period for a planet orbiting a mass = 1 sol with a 24-hour year, it's got a semi-major axis of 1.82 million miles - far and away beyond the Roche limit, still beyond the corona, b...
