There isn't much "science" in it to hold together. Obviously the entire wormhole machine, the wormhole trip, what was on the other side, etc. was fantasy, and what's left is just receiving signals.
Almost all science fiction has some leap of imagination to make the story work. The Expanse tv show (and books) have the Epstein Drive and the protomolecule stuff. Obviously Star Trek is even more fantastical, so is Dune, or almost any space science fiction. Maybe Red Mars, Green Mars, Blue Mars is an exception (one has to assume fully terraforming Mars in a couple centuries is in fact doable), but there's no movie or tv show for those books.
i still maintain that the most interesting read on contact is as hard sci-fi. there aren't any aliens. the machine was a trans-cranial magnetic induction rig designed by hadden to punk the world's preeminent atheist with a religious experience, and by extension, punk humanity.
Wormhole devices in movies keep puzzling me for quite some time - why does a significant number of them look like rings rotating around each other?
Contact is one example, another is Event Horizon. The Terminator also had a similar looking time machine.
Currently, our sole way of manipulating spacetime is by cramming a heck of a lot of matter in one spot, which is to say that we don't really do much of it. Any way short of crushing down mountainsful of matter into a thimble would necessarily be more complex, with more moving parts. I can only think that rotation would come into play, and if one dimension is good, three would have to be better if you want to shred spacetime.
I don't think it's doable but in the sense that you want something to visually convey it, it may as well be the equivalent of lightning to stand in for electricity.
Not sure if there's some pseudo-physical explanation, but I've imagined it has something to do with visualizing the three dimensions that are manipulated.
Interestingly both Event Horizon and Contact (movie) are from 1997...
1) check out bitwarden + aegis - both seem popular as another tools
2) Reinstall your linux desktop instead of upgrading once in a while ( remove worms). Make sure you have all updates regularly.
3) When you are developing be careful with libraries - for example pin your versioning in python in the event you get a bad repo
4) use adware blocker to block malware in firefox
5) with keepassxc use the extra file - for security - call it random.mp3 and do not keep it in the cloud even encrypted
6) keep your otp passwords separate
7) use u2f for your main email account - yuibkey or other cheap alternative.
8) explore ssh using yuikey
9) use personal firewall on laptop
10) Use drive encryption for your laptop - backups need to be all encrypted as well
11) Bonus - have separate email account only for password resets that is very hardened and you don't log in regularly. Maybe with 2 different 2 factor auth on it.
12) Bonus 2 - have separate phone number for 2 factor sms authentication that people can't know about - (voip or tosser phone)
1) require an initial investment and promise above-average returns
2) money cannot be withdrawn for a certain period of time in exchange for higher returns.
High investment returns with little or no risk.? Overly consistent returns?
Your argument is that if I buy an ETF for gold and they charge 2% to keep the gold safe and manage it. This etf is a ponzi scheme as they need have holders to keep the thing going.
As the transaction fees go to miners you could then argue VISA and mastercard are ponzi schemes?
