Must be a guy. Probably trying to figure out how to get to Venus.

what is the minimum and maximum size of a star? i.e. what is the minimum mass to ignite hydrogen fusion or whatever generates heat, and what is the maximum size where it just collapses into a black hole?
CrazyLikeGollum@lemmy.world 6 months ago
The minimum is about 80 Jupiter Masses. Smaller than that and you can’t start fusing.
Maximum size is harder to answer. It’s determined by the Eddington Limit. Which describes the luminosity at which radiation pressure is enough to overcome gravity for a certain mass.
It’s thought that the maximum mass of a star is somewhere around 150 solar masses, but there’s some evidence to contradict this, as we’ve seen a handful of very old stars with masses or luminosities higher than they should be.

You can’t get to this star in Elite Dangerous, but you can get to VY Canis Majoris which is 1420 radii

That’s the only reason I opened this post; i.e., it may be “engagement bait,” a recent online trend.
Bishma@discuss.tchncs.de 6 months ago
I assume this in regard to the possible evidence of life on mars, recently announced.
Engywuck@lemmy.zip 6 months ago
I’ll go with Occam’s razor instead and say that’s just a small mistake 😛

Here’s the galaxy and our approximate location in this system. To give you an idea of scale … the galaxy is estimated to be about 100,000 light years across. Meaning that if you could travel at the speed of light (which is impossible), it would still take you 100,000 years to cross the galaxy from edge to edge.

now imagine how insanely long it would take for any extraterrestrial species to fly through all that and meet us. that might explain why we haven’t met any of that yet.
IsoKiero@sopuli.xyz 6 months ago
It’s just highly improbable to cross the galaxy in less than 100 000 years. You just need a device which generates infinite improbability and that’ll pass you trough every single point in the universe simultaneously and you can just stop where needed. Side effects may apply.

Epic Spaceman on Youtube had a great scale realization method. If out galaxy was the size of the United States, our solar system would be somewhere around the city of Denver. The neighborhood stars we can individually see with our eyes would be the area of the Denver city lights. The Sun would be the size of a red blood cell, and the solar system's expanse would be the size of a fingerprint.

I always loved those examples that show the scale of planets, stars and systems. I remember years ago before I got on the internet (yes I’m that old), reading a comic or book, I can’t remember where … all I remember is the cartoon and illustration.
If you made a scale model of the galaxy and fit it in between the earth and the moon … our sun would be the size of a marble and it’s nearest neighbour would be about a mile away. And some of the largest stars would be about the size of an average office building.

100000 years from an outside perspective, but because of time dilation you could make it take arbitrarily little time from your reference frame.

I liked the character’s from Project Hail Mary perspective. The fact that we experience less time the closer we are to the speed of light is almost like an invitation to explore the stars.
Another things that gets me is the time experienced by black holes. We would think of the black hole at the center of the galaxy as some enduring, permanent thing, but with so much gravity, from the black hole’s perspective it may only exist for a fraction of a second.
ininewcrow@lemmy.ca 6 months ago
I don’t fully understand how the science and theory works around all that … all I understand is that it is so unbelievably far away that in order to cross any of those distances or even think about crossing those distances, it begins to break our normal understanding of speed, distances and time.
ininewcrow@lemmy.ca 6 months ago
Here’s another perspective … this is local galactic group. Our nearest galactic neighbor is the Andromeda Galaxy … it’s located about 2 million light years from us. Again, if you could travel at the speed of light (which is impossible), it would still take you 2 million years to get there.
Another way of thinking of it is that the light we see from Andromeda today started it’s journey when our first prehistoric human ancestors first evolved in Africa 2 million years ago.

If you could travel at the speed of light, the only tim it would take you is the time spent speedign up and slowing down. Traveling at the speed of light stops the time for you.
