Yes to both. https://www.sciencealert.com/icarus-blue-giant-most-distant-star-ever-seen-hubble-9-billion-light-years#:~:text=When light passes through this gravitational field%2C it,dependent on exactly the right alignment of objects.

You put a lot of time and effort into these threads, Do you ever do anything with these ideas of yours, like apply for patents or seek funding?

Been reading about kinetic energy weapons, and it got me thinking, say a 200 tonne passenger jet crashed into London at Mach 8, what would the resulting explosion/shock wave be like. Would it have the potential to flatten London, or would it be just a big ball of flames? Also, during the planes descent, would it speed up due to gravity or slow down due to a loss of thrust and friction?

Thanks so much for for replying. 🖖🏻

Agreed, which is why we have programs like prevent. https://fullfact.org/law/what-prevent-strategy/ Good. I'm happy with this democracy thing we have thanks. If it ain't broke...

Interesting theory. I can't comment on most of it unfortunately, apart from this. https://www.sciencealert.com/we-just-got-more-evidence-that-the-moon-is-tectonically-active

Never heard of this, any chance of starting this thread?

If we replaced the engine with a thermo-nuclear engine, and used water as the fuel, could you produce enough thrust from the steam to get into orbit? And considering the amount of water on earth, would it make a good engine for space exploration?

Not a scientist, so just my 2 cents, I'm on Quora a lot, from various things I've read on there, Goldman Sachs seems to be fond of people with a PhD in physics. Some of their best people have backgrounds in physics. To do with analysis and things like that. Money's not bad either.

Maybe that's why they only sent one signal. They weren't trying to say hello, just seeing if anything replied, so they could evaluate if we were a danger or not before revealing themselves. They could've sent one out in every direction and just waited for any responses.

If we add stuff on for the next generation of them, What else could we do with it? would it be possible to attach solar panels to the top of them, then use the energy to power lasers or radio waves to power aircraft? what about a solar farm, I've read they'll be around 48000. would it be possible to support space manufacturing?

I suspect there's also an element of 'have you seen how big my dick is' going on.

Some of the residents on sites like these have been interacting with the same people for over 10 years, sometimes across multiple sites. I was wondering, Do you ever keep in touch with anyone away from the site? Also, what's it like when someone you regularly interact with for a number of years stops showing up, do you ever feel like you've lost a friend. Sorry for being personal, tell me to f^*k off if you want, I'm just curious.

He's not been around in awhile, very strange. Does anyone know if his/their absence is permanent? Something i've noticed on several different forums now, is that when a new expert arrives and seems to stick around, one of the resident experts disappears. I was wondering, as these forums are kind of smallish, do staff/mods feel morally obligated to stick around longer than they want too until a replacement shows up, so not to harm the site?

I can't unsee it. Eh?

https://www.scienceforums.net/topic/7677-min-energy-needed-to-launch-to-the-sun/ found it! Completely pointless now of course. Thought I'd put a link anyway.

Supermarket chain. Basically the same as Wal-Mart but British. edit: cross posted with a much better answer.

Not fond of them, just not familiar with them. We don't have Wal-Mart, They own ASDA over here. I know a lot of people don't like them, but I've never heard of anyone suggest lawsuits for antitrust violations.

A Brit here, why Wal-Mart, what have they done?

Wiki says two up, one down. Just read this on Quora. Which is true? https://qr.ae/pNe457
