"nobody could’ve done what i had achieved.”
“spoke, look at you bro.”
oh yeah what I meant by this! watched Interstellar with my brothers last night. two of them are science nerds! so well one has seen it and one hadn't before
so afterward I sat at a table with the one that hadn't priorly seen it and asked scale of 1 to 10 how realistic he felt it was. he got immediately hung up on the mathematics of the time as portrayed on screen, we jabbered about that for a while
... and second brother comes in. "Okay what you NEED to know," he says, and he's apparently talked this over with the fandom several times over, and he just takes off in this conversation and here I am sitting between two brothers who are going off about the science of well everything practically
inwardly I'm kinda making this face :D because I miss these sorts of arguments (and also I get to be a part of it)
and bro
okay yeah I could go into the whole wormholes and black hole/white hole and time shift and that sort of thing, it was a good conversation, but I'll save that for another time
and there was the whole me bringing up The Martian as more realistic and then us picking it apart too (tbh it's very good tho) but again not the point of tonight's tale
the point being
loved ones are so precious
loved ones are so precious when they're engaging in the thing they love
love languages can be arguing over science technicalities in science fiction and cinema
I love these people so much and I love that I get to be theirs.
bringing back the interstellar fandom one cranky science nerd at a time
That moment when you dive into what you assume is a pool, but you end up in deep space instead.

All the stars, planets, and galaxies that can be seen today make up just 4% of the universe!! The other 96% is made of stuff astronomers can't see, detect, or even comprehend. These mysterious substances are called dark energy and dark matter. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀ Follow me. for daily space facts Follow 👉 @_space___lover_ 👉 @_space___lover_ 👉 @_space___lover_ 👉 @_space___lover_ 👉 @_space___lover_ 👉 @_space___lover_ ------------------------------------------------------------------ --- --------------------------------------------------- -- ------------------------------------------ #relativity #cosmos #spaceandtime #space #multiverse #universe #quantummechanics #bigbang #equation #maternityphotography #outerspace #spacetraveler #hubble #timetravelers #isro #eventhorizon #wormhole #bhfyp#sciencefacts #theoreticalphysics #blackhole #milkyway #artgalaxies #physicsmemes #sciencememes #_space___lover_ https://www.instagram.com/p/CCZ3Notnb8v/?igshid=o78rmq5m1hin

What is a Wormhole?
Wormholes were first theorized in 1916, though that wasn’t what they were called at the time. While reviewing another physicist’s solution to the equations in Albert Einstein’s theory of general relativity, Austrian physicist Ludwig Flamm realized another solution was possible. He described a “white hole,” a theoretical time reversal of a black hole. Entrances to both black and white holes could be connected by a space-time conduit.
In 1935, Einstein and physicist Nathan Rosen used the theory of general relativity to elaborate on the idea, proposing the existence of “bridges” through space-time. These bridges connect two different points in space-time, theoretically creating a shortcut that could reduce travel time and distance. The shortcuts came to be called Einstein-Rosen bridges, or wormholes.
Certain solutions of general relativity allow for the existence of wormholes where the mouth of each is a black hole. However, a naturally occurring black hole, formed by the collapse of a dying star, does not by itself create a wormhole.
Wormholes are consistent with the general theory of relativity, but whether wormholes actually exist remains to be seen.
A wormhole could connect extremely long distances such as a billion light years or more, short distances such as a few meters, different universes, or different points in time
For a simplified notion of a wormhole, space can be visualized as a two-dimensional (2D) surface. In this case, a wormhole would appear as a hole in that surface, lead into a 3D tube (the inside surface of a cylinder), then re-emerge at another location on the 2D surface with a hole similar to the entrance. An actual wormhole would be analogous to this, but with the spatial dimensions raised by one. For example, instead of circular holes on a 2D plane, the entry and exit points could be visualized as spheres in 3D space.
Science fiction is filled with tales of traveling through wormholes. But the reality of such travel is more complicated, and not just because we’ve yet to spot one.
The first problem is size. Primordial wormholes are predicted to exist on microscopic levels, about 10–33 centimeters. However, as the universe expands, it is possible that some may have been stretched to larger sizes.
Another problem comes from stability. The predicted Einstein-Rosen wormholes would be useless for travel because they collapse quickly.
“You would need some very exotic type of matter in order to stabilize a wormhole,” said Hsu, “and it’s not clear whether such matter exists in the universe.”
But more recent research found that a wormhole containing “exotic” matter could stay open and unchanging for longer periods of time.
Exotic matter, which should not be confused with dark matter or antimatter, contains negative energy density and a large negative pressure. Such matter has only been seen in the behavior of certain vacuum states as part of quantum field theory.
If a wormhole contained sufficient exotic matter, whether naturally occurring or artificially added, it could theoretically be used as a method of sending information or travelers through space. Unfortunately, human journeys through the space tunnels may be challenging.
Wormholes may not only connect two separate regions within the universe, they could also connect two different universes. Similarly, some scientists have conjectured that if one mouth of a wormhole is moved in a specific manner, it could allow for time travel.
Although adding exotic matter to a wormhole might stabilize it to the point that human passengers could travel safely through it, there is still the possibility that the addition of “regular” matter would be sufficient to destabilize the portal.
Today’s technology is insufficient to enlarge or stabilize wormholes, even if they could be found. However, scientists continue to explore the concept as a method of space travel with the hope that technology will eventually be able to utilize them.
