Don't worry about that. Its just speculation. Currently nobody is going anywhere, and I hardly think that video was a sound source of information. I find it unlikely to impossible to invent a time machine, and currently no such things has been achieved.
As is said before, we don't even know that this even qualifies as a time machine, as per the normal sense of the word anyway. As I showed in post #39 and before, there mere measurements described in post #35 are not good enough to warrant something being a traditional time machine. All I see is an entertainment programme.
That is just a silly and speculative fantasy-based statement. There is currently no evidence of this, and the simple fact is people just make it up. As I said before, there is no evidence that a real time machine has been invented, nor sufficient evidence that it even could be invented.
Even if so, all this would mean is human meddling in the "new universe" and that would be equivalent. It would also spread the toxic plague of humanity to a new universe.
Fortunately, these claims are just a non-sense. The idea that going back or forward in time and changing events would somehow magically create a new universe is deranged. There is simply no evidence nor is there any rational explanation as to how changing some insignificant detail could generate enough energy to create a new universe, and how that new universe could magically be created. Its just cloud-talk.
