Astronomers Have Detected Strange Planets Just Outside Our Solar System

The cosmic scale is so difficult to comprehend and even imagine in a way that is anywhere near relatable to the human scale that it still astounds me every time! I have studied physics and astronomy since I was a kid, and I am always fascinated by the vast scale of space. The closest star is still so far from us that it would take us tens of thousands of years to travel to it using our current technology. Even if we were able to travel at the speed of light, it would take over four years to get there! The thought of being stuck on a spacecraft for multiple years gives me the shivers!

Obviously this is no serious issue with your presentation, just a note for the algo.

[@vazap8662]

Fascinating. I'm a little confused though about Proxima Centauri's density... if its diameter is roughly 1/6th that of the sun, that would make its volume roughly 1/216th that of the sun right? Its mass being roughly 1/10th that of the sun, wouldn't that make its density roughly 20x that of the sun and not 40x?

Too much rounding too early. Errors adds up. 100 / 15 = 6.667 ≠ 6 6.667^3 = 296.3 ≠ 216 100 / 12.2 = 8.2 ≠ 10 296.3 / 8.2 = 36.15 ≠ 20

So, the Alpha Centauri system is actually a solution to the three body problem?

[@kruksog]

That is not what is meant by "solution to the three body problem." The alpha centauri system is an example of the kind of situation described by the three body problem, but there is no closed-form solution to the three body problem, meaning there is no mathematical expression which can predict the orbits of masses in such a configuration (at least one not in terms of derivatives, which is covered by "closed-form," I just want to be very clear.) So this is not a solution to the three body problem, but an example of the situation described by the three body problem.

[@markshillaw3536]

⁠@@kruksogwow I couldn’t have explained that better myself you must have a high IQ well delivered

[@poruatokin]

The Alpha Centauri system is not a true three body system. You have two relatively close stars that orbit a common center, and you have Proxima Centauri that orbits the same common center so far out that it does not significantly influence the two main stars. The result is a stable system.

Even Earth's atmosphere has changed over geologic time. The atmospheric composition of Earth in past geologic ages would be lethal to us, but the creatures at the time were well adapted to it.

[@curtcoller3632]

I can't wait 12 billion years to prove you right or wrong. Plus - to reach Proxima Centauri in about 4 years requires light speed. But currently we travel at best about 0.05% of LS. If my math is right - that would require a minimum of 8000 years to get there. So, even if we can double this speed during the next 2 years (which won't happen) it would cut the travel time in half. So if we start "microprobes" - little tiny bots in 2036, what advantage would that make for us? We aren't able to get digital answers in less than 4+ years and respond with "orders" in another 4+ years (unless we quantum entangle our brains with the bots out there) from the date the little 2 gram heavy bots arrive. Acording to Alex we didn't find any "desirable" planet. So, my suggestion is to start research on "faster" space travel. But why would anyone want this, when we can't even prevent particles to hit our spacecrafts at the speeds today. To send tiny bots there is pure lunacy. Just because we will have them in 2036? Okay, good luck. At some point I ask myself, are the "scientists" mostly brain damaged? Who else can see that they are "creating a world out of dreams"?
