So we can't figure out how super massive black holes got so big so fast. Could super massive black holes have formed when the universe was young, incredibly dense, and before atoms formed? This way of direct collapse make sense. There was no hydrogen atoms to fuse, so there was a runaway collapse.
Having read the comments on my other post it has me wondering.
Due to the constant lack of investment in space exploration and the huge engineering hurdles required to explore space, could it be that we don’t make any more groundbreaking progress for perhaps a 100 years maybe more?
I was reading about sending a probe to Europa to search for life and it is remarkable the level of complexity it would take to melt the ice all the way down to the water while keeping communications and possibly even bring a sample back to earth.
And I was thinking, maybe we won’t do this. Maybe not for a hundred maybe 200 years. Maybe we don’t conduct any missions to find life at all. We have the Europa clipper but it’s not going to tell us whether there is life or not, not for certain
I know we are planning to colonise mars which is amazing but maybe that’s where we end up stopping. Maybe we don’t look for life in Europa or the other moons for centuries if at all…
Edit: by slow I mean less passionate/dedicated. Compared to the buzz around going to the moon it seems odd because finding life outside of earth seems way more exciting than going to the moon (which we knew it was uninhabitable)
What I mean by this is that the question of life outside of earth is one of the biggest questions for humanity to find an answer to.
I think about how fast spacex is working both to improve their rockets and to reach their goal of colonising Mars. How they’ve broken records with their rocket engines and how they’ve made space travel so much more affordable all in about 2 decades.
Yet we have only just launched the Europa Clipper and to my knowledge we haven’t had anything fly close by since the 20th century.
We haven’t landed anything on europa either.
And for mars, we only have 2 active rovers. I know that these things aren’t easy and are expensive but difficulty and price don’t usually stop NASA/humanity as a whole from exploring space.
Why haven’t we sent a rover to europa? Are there any plans to? Or why not even more flyby missions? Why are we only now sending a flyby probe in 2024?
Why not tens or hundreds of rovers on Mars? Ones that bore tunnels and explore deep underground, ones that go faster etc?
What about other places possibly capable of supporting life like other moons of Jupiter and Saturns as well?
Hope this is the right place to ask, but does anyone have any recommendations for YouTube videos about things like space/the universe, reality, other dimensions, crazy physics, quantum physics, etc. that will mess me up mentally, make me have trouble falling asleep cause I can't stop thinking about it, and question life itself?
I recently watched the video "What is Reality?" posted by the History of the Universe channel, and I loved it (really recommend). I still think about it and want to find more that are similar to this.
They can be based on facts, theories, maybe a little fiction, or all of the above. Doesn't matter, I just want it to mess me up.
Thanks!
I live in washington state (PNW).
Can someone guide me on how to watch the comet?
I am newb and no sense of direction.
The general instructions i got is, watch the sky 30mins after sunset.
But i dont know where to look in the sky.
Any help would be really appreciated. :)
I was shooting the comet last night and in my shot there is a straight red line and what seems like an impossibly straight set of lights to be stars. Are these starlink satellites? It was a 90 second exposure on a star tracker, so if they were moving at a different speed than the stars generally they would look like a line I think. Just to left of the comet and its trail. Shot at 200 iso so don’t think noise is an issue, plus noise wouldn’t be that regular.
