How about the wormhole theory?

When I mentioned ftl that was one of the theories I was thinking about.

The theory doesn't actually forbid FTL, it just works out the consequences of assuming that it IS forbidden.
It certainly seems to be true on the basis of current knowledge that the speed of light is constant for all observers and is the cosmic speed limit, but there are known quantum effects that seem to require instantaneous transfers of information. Despite their great successes, quantum mechanics and general relativity remain fundamentally inconsistent, they can't both be right. Physicists wouldn't put it that way, they'd say they're incomplete, but it amounts to the same thing. There's at least one more layer of reality science hasn't penetrated yet.
Personally, I incline to the view, on the basis of no evidence whatsoever, I just find it emotionally satisfying, that there are many more layers, reality is fractal in the sense that it'll show the same level of complexity no matter at what scale we examine it.

I pretty much agree with everything you say and definitely agree that, emotionally, I like thinking that ftl is possible. We just haven't figured it out, yet. Maybe I'm just an optimist, but when it comes to science, I have great faith in our ability to find a way to do anything we want to do. This includes terraforming, and not nesasarily having to find a hospitable planet.

No such thing as science fiction, we just haven't figured out how to make it a reality. Lol

It's not actually a theory in itself. Wormholes, tunnels between points in spacetime, are a possible consequence of general relativity, but are still highly speculative. Nobody's ever seen one, or as far as I know produced any plausible way to construct one, but they are allowed by the theory. Doesn't mean they exist, or can be created, but there's an idea popular among some physicists that one of nature's basic rules is that anything not forbidden is compulsory. Very bad idea for a human society, that's a monstrous tyranny, but as a law of physics it has a certain appealing symmetry to me. It's like saying anything that CAN happen, WILL happen.

Which certainly seems to be true of my life...

Now THAT is an idea I really like.

Just how much fuel is going to be used to have go around and around 24 times (how close is the 1st loop) rather than fall as fast as gravity can pull oy and not one loop is completed. All 24 should be closer than mercury.

These records will fall again and again over the course of the Parker Solar Probe's $1.5 billion mission, which began Aug. 12 with a liftoff from Florida's Cape Canaveral Air Force Station. The spacecraft will study the sun during 24 close flybys over the next seven years, getting closer and closer to our star with each encounter.

The Parker Solar Probe's final flyby, in 2025, will bring the craft within a mere 3.83 million miles (6.16 million km) of the sun's surface. And the sun's powerful gravity will eventually accelerate the probe to a top speed of around 430,000 mph (690,000 km/h), NASA officials have said.

How much does it weigh 4M miles away from the surface of the sun?? I assume the breaking rocket is a tad bigger than the ones left on the moon.


Why not land it on Mercury and it can send back data for years like the Mars Rovers are, . . . . cough.

Your open parade of your lack of knowledge is wonderful to behold.
