RIP James Lovell

[PhotonWrangler]

Dang. The hero of the ill fated Apollo 13 mission has passed. Talk about cool and collected under pressure.

RIP sir. You were a national treasure and a class act. Thanks for showing us How it's Done.

I met him in 1995, after the Tom Hanks movie
had been released. He made an appearance
(talk and Q&A) at the *BEAUTIFUL*
Rialto Square Theatre in Joliet, Illinois !

:clap:

Very open, approachable, and
"down-to-earth" fellow.

I was pretty young during the Apollo program, but it sure captured the imaginations of a lot of kids. I didn't go into the space program, or even a STEM occupation, but I did dabble with Estes rockets for a little while. Still have some of the stuff packed away in boxes. Maybe some day I'll shoot a few off for my grandkids, and perhaps inspire them into the space program. I assume Elon is hiring...

In regards to interstellar travel, why are we still thinking 3rd dimensionally?

Imagine if science was all about proving what we already know, we would never learn anything new...

An admirable person has passed, and an opportunity to remember those less famous who deserve equal admiration.

I haven't read the book, but the film was very good. Watch the trailer.

Unfortunately, I don't use IG...I will take your word for it

You don't need an IG account to read the tribute though. I don't have an account either.

Sad that he's gone. I was hoping he would have made it past 100. At least he was around to share his experiences with several more generations.

If you mean that we'll eventually have faster than light travel, I tend to agree. It obviously won't be physically exceeding the speed of light, but rather warping space to give effective velocities above light speed.

Or, we shunt everything out of the way, including space...faster than light, at least physically, would rip holes in spacetime...but let's save that for another thread lol

He signed my pilots license years ago. Very nice for the few minutes I was around him.

For an interstellar-scale warp path large enough for a human ship to reach even Alpha Centauri in days, the negative energy requirement would exceed the total radiant output of a star for years or centuries. And...

...in the context of warp drives and wormholes, “exotic matter” is a placeholder term for a hypothetical material with negative energy density or negative mass that would violate the known energy conditions in general relativity. There is no evidence this matter exists or can be harnessed.

But we can fly here on our beautiful earth. :-)

We assume that black holes are massive because of their gravitation. But what if I told you that black holes are aptly named because they are actually 4th dimensional holes, (holes in spacetime)? I have a theory that the net mass of the matter in the universe will roughly equate the gravitation of all the black holes in the universe. Whether mass is positive or negative, it will exert a net positive gravitational force on a 3rd dimensional space. Think of a cartesian grid, if we remove anything below x=0. Whether x is negative or positive, y is always positive. In the same sense, it could be more applicable that everything y>0 would yield a positive x value. (Negative y or x in relation to x>0 or y>0 respectively would be every other potential outside our known universe, so for our intents and purposes, we should conceptually disregard it for now.)

It's a methodology based on precalc, polar coordinates and 3d intersections of a 2d plane in that 3d space. We need to find the 3d intersections on a 4d space. Conceptually it's simple enough, but practically it's a different story. Given the human propensity to full-*** a half-brained understanding, i wouldn't be surprised if our first attempt at "warp" causes a few rifts somewhen.

Well, you know, there were a few people that were afraid that when the first atomic bomb was exploded that it would ignite the atmosphere, and fry everyone. Didn't happen. But, assuming we cause a few "rifts" somewhere...well, you can't make an omelet without breaking a few eggs. Sometimes you just have to close your eyes and go with your gut. Maybe the world ends, and maybe not. You won't live forever, anyway.

"Thermobarics". However, with the proper calculations and "defensive programming" (foolproofing), those risks can be mitigated. The issue is when professional coin tossers think what they're doing is the same as playing Go or Chess.

There used to be a market for innovation and efficiency, but it is corrupted with certain types of "education" drilling into impressionable minds that "this is the best way", when in fact there should be a little footnote that says "at least that we currently know of". If cautious open-mindedness were taught in homes and schools, we would have much better designed products, much less bullying, much less crime, etc.

Instead of checking our work, we have been relegated to passing the buck in our "warranty" mindset. Warranties are being abused by corporations because it COSTS less to quick push a market for profit then use consumers as active troubleshooting. But it is detrimental for innovation because it locks the problem solvers into a particular mindset and specific type of design philosophy.

It may seem like my rant is all over the place, but it's a big picture view where it's all interconnected. Most people only see snapshots, but are willing to ask questions to ascertain a broader view...

There was a day when we thought traveling faster than 30mph in a train would cause illness. Going any faster would most likely kill us.
Breaking the sound barrier, if not impossible, was too dangerous for humans.

Astral projection is a real thing. When science and the super-natural meet, we'll travel faster than light physically travels. What I mean is, light isn't bound by known physics. We just haven't figured out how to measure it any other way ...yet.
The Big Bang is an example of that. It wasn't an explosion in the traditional sense where particles were filling empty space. It was a 'thing' that expanded faster than light can be measured now. It's still expanding albeit somewhat measured.8

*I personally believe that we've gotten this all wrong and that is why we keep getting surprised the deeper we look into the universe. The math doesn't add up. We're measuring light incorrectly ...incompletely.

Einstein was working on a GUT...but you'd have to be GOT to comprehend a GUT. And we know only GOT is GUT.

Time doesn't exist. The present can't be proven because there is no "present". All time is happening "all the time". The Theory of Relativity falls apart if time exists. Light is more than photons. More in what way is only a theory at best. But there has to be more to light than just photons. Science hasn't been able to come up with an equation that makes it all make sense. Space. Time. Matter. Light. Motion?

Way over my head. But fun to think about. Like a child would think about the ocean's depth, or why chocolate tastes so good, or wondering how magnets work.
