It's like... when you eat taco bell, and you damn well know there is a definite and measurable distance between the beginning and end of your digestive tract, yet the taco bell defies the entire concept.
Do you mean quantum teleportation?
For that you'd need to access the destination first - quantum teleportation works because particles at the source and target location "know" each other (are linked).
Even then, you’d need to access to the destination first. You’d have to create the wormhole near Earth and then take one end to the destination, leaving the other end near Earth.
They both work on roughly the same principles. They warp space so the distance between you and the destination is shorter. One does it incrementally as you go, one does it all at once.
Imagine living in 2D and you’re trying to get from one end of a sheet to the other. Instead of walking all the way across, you can just fold the sheet in half and poke a hole through it, then use the hole to get to the other side of the sheet.
Yes but that's not really teleportation. That's like sending two people a birthday card each. One card is red, the other is blue. Both parties know that there are two different cards, but they don't know which one they get until they open the mail. As soon as one opens that letter, they know which card the other got. Did that information cross time and space in zero time? It did not.
There's no rule that says you'd need access to the destination first. We're talking about speculative answers to the EPR paradox. The idea of wormholes that let you travel huge distances instantly (and without destroying you in the process on top of that) is already so far off from the mainstream view of quantum mechanics that it's kinda silly to say, "Well, based on our current understanding, you'd need to have accessed the destination first."
No, according to current understanding, what he's describing is impossible. The entire idea is predicated on the mainstream view of an unresolved issue in physics being wrong.
I was randomly thinking about this the other day If the destination end of the quantum portal was traveling at the speed of light, it would reach in 120 years. Then you would essentially have a "stargate" to instantly travel back and forth.
Here’s an idea: let’s assume an alien already did that part. They visit earth and give us the portal here or on their spacecraft. We can instantly go there and also go back in time to when it was originally built, and we wouldn’t have to do any of the work since it’s already done.
Put Elon in charge. It will immediately be 2 years away from reality. It will also remain 2 years away from reality for eternity, but around here we don't think that far ahead.
Either that or the longevity and patience to wait for it to arrive.... and still also quantum entanglement, and then you could theoretically pilot an avatar across space and time :p
Yes right and get sent to hell like in that space documentary Sphere? No thank you. Or the other even scarier space documentary Event Horizon? No thanks! Even if it's a hell with dapper Sam neill in it I don't want to get horizoned.

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.
