A bit of silliness on a bank holiday weekend. You can have one of the above. Teleport - you choose the location Time Travel - you select the date you want to go to. Which do you choose? You can't have invisibility, as that's not possible, silly.
I was going to say that time travel without teleportation would put you in a world of bother immediately unless you're happy dealing with the vacuum of space, but then if your teleportation is instantaneous then I think that might apply the other way round as well?
Well as I understand Einstein's general theory, time and space are simply properties of the same fundametal thing, the space-time continuum. Or summat.
Yes they are, I think the point being made was if you travel in time but not space then the Earth will have moved and you'll end up in empty space. So for space time "coordinates" you'll need both. If I were to arrange to meet you I would need to give you both a time and location. As one would be useless without the other.
Time travel would be fun but you'd have to accept that your kids would almost certainly cease to exist. Teleporting. You'd be practically invincible. The ultimate weapon. Assassin. Able to stop wars single-handedly.
Time travel. Would like to witness the whole of the rise of Hitler and WW2 through to 1945. From the comfort of a comfy chair. Teleport. Tuesday night matches at Barnsley, when it's pissing down with rain, cold and horrible and we've lost yet again miserably. I could push a button and be home in bed 50 miles away instantly.
Although you and I both know that most males would use it to "coincidentally" turn up in Beyonce's bedroom just after she's jumped out of the shower.
Teleport for really boring reasons like skipping my one hour each way commute. I love both my job and where I live so I’m not changing either but gaining an extra 2 hours back a day would be amazing. Time travel doesn’t appeal to me. For it to be really interesting you’d have to go somewhere sufficiently different to now and then I’d struggle to adapt and not stand out like a weirdo. Or it’d be really frustrating not being able to change anything for fear of what chain of reactions you may set off, or to not accidentally blurt out things you know in hindsight.
For me, as I mentioned above, I’d choose time travel—specifically to the future. I find the possibilities utterly fascinating. Modern humans have been around for roughly 200,000 years. When you consider that the average lifespan of a mammal species is about 1 to 2 million years before extinction, it puts our current moment in perspective. Are we still at the very beginning of our story, or closer to the end? What makes us unique is that, unlike any other species, we possess the capacity not only to destroy ourselves but also to prevent catastrophes. We can detect and potentially deflect comets, mitigate climate change, and reshape our environment. That dual potential—for self-destruction or survival—makes our future especially compelling. Interestingly, around 7% of all humans who have ever lived are alive today. That naturally gives us the illusion that we’re at the peak of civilisation. But are we? What comes next? Will we expand beyond Earth and begin to colonise the solar system? Will we solve our global challenges, or be undone by them? To witness where humanity goes next—whether towards the stars or into decline—that’s what would make time travel into the future the most tempting invention for me.
Time travel. I'd love to be able to whisk my kids and grandkids back in time to meet my Dad, who died before any of them were born. Hed have been a lovely grandad, bless him.
