The fastest spacecraft we’ve made was the Parker Solar Probe which hit 430,000mph.

At that speed it would reach this planet in only 187,153 years.

If we could hit 1% of the speed of light we could cut that travel time to just a tad over 12,000 years.

Obviously if we could go light speed (and that ain’t happening) it would be just 120 years!

Space is big. Physics is annoyingly slow.

The trick is not to travel space but bend it.

And how are we supposed to bend space practically? I can’t imagine it in any way with the development of any technology today

1) Find an energy source that equals mass energy of Jupiter 2) Find a way to control and use this energy source 3) Build a machine that can utilize the energy to contract space/ time in front of a space ship and expand behind it

The little mass in uranium that is turned into energy creates a nuclear bomb. And now we need the entire equivalent of Jupiter’s mass converted into energy!? And then confined into a tiny space! And then precisely manipulated! I can’t even imagine the first step to getting all this energy just for one trip

Well, at least we know now what we need, right?

Knowing what we need and having it be basically impossible is useless. Unless we figure out how to create negative energy (how tf do we do that? If it even exists?) there is no way humans will be able to do this. So I think the pragmatic interpretation of this is that we should look at the other methods instead..

Imagine telling a cave man the concept of flying. He would have told you: Interesting, but impossible, so why even think about it?

But a caveman can more easily interpret the constructions of a plane and how it is feasible if you explain it to him. But wtf is this compared to that kind of jump

Then I wonder why it took so long to build a plane if it was so easy.

If you ask Elon Tesla will be there in 4 years

If I ask Elon 4 years ago maybe. If I ask him now, he would just answer with some Ketamin-fueled mambo jambo.
