The tool instrumental to the exploits of Michael J. Fox’s time-traveling Marty McFly would have ended on more than one occasion if not for the help of the futuristic skateboard.

The fantastic floating device called a lifter has no moving parts, no onboard fuel, and no shortage of wide-eyed admirers. Even inside NASA.
The super power issue being invisible the antigravity underground A user’s guide to time travel 8 super powers.
Some of the leading theories of quantum gravity prohibit it, while in others, time travel happens all the time.
The prospect of reliving a past moment from Earth’s amazing history or skipping ahead of the future is a tantalising idea widely present in science fiction. But physicists who spend their days pondering the mysteries of time and space believe time travel might be within the realm of possibility. This does not mean scientists will develop TARDIS-like time travel machines straight out of Dr Who any time soon. Instead, the theoretical and physical frameworks are there to show moving forward in time can be achieved – with a small catch.
To me cryonics just makes sense. It may not be pretty but, just like open heart surgery, it is one of those things that, without any guarantees, can possibly extend your life [very] substantially. Thus, especially given the alternative, I just can’t quite make sense of the slow rate of adoption evident not only in North America but also across the world. And so I am always happy to discover new books that lay out the scientific argument for cryonics while making it easily digestible and giving it a very personal, human perspective. Since the most recent book, I thoroughly enjoyed on this topic was Frozen to Life: A Personal Mortality Experiment I thought that D.J. MacLennan will make an excellent guest on my podcast. I was not wrong about that.
During our 1 hour conversation with D.j. MacLennan we cover a variety of interesting topics such as: why he decided to write Frozen to Life and who is it for; cryonics as a glass-state time travel; why he chose neuro- rather than full-body preservation; the costs and rate of adoption of cryonics; the culture, conservatism and geography of his home on the Isle of Skye; transhumanism and transcending limitations; the differences between Max More and James Hughes; his fear of death; the promise of chemical brain preservation; mindfulness and meditation; writing a transhumanist take on The Wizard of Oz and potentially on Grim’s Fairy Tales…

Time travel is complicated, which means it’s time for some charts.
I’m particularly fond of this one, created by fan Oren Bell. In an elaborate, detailed interactive timeline, Bell explores the various realities created by the actions of the Avengers in Avengers: Endgame, tracing the actions of each protagonist and their impact on the timeline(s). Simply click a character, and you can follow their journey, from the present to the past to the present again.
I was hoping to post this earlier, but a heavy dose of writer’s block set in (I met a girl, and no, this blog didn’t help — but she is a physicist!) I also got lost in the rabbit hole that is quantum teleportation. My initial intention with this series of posts was simply to clarify common misconceptions and to introduce basic concepts in quantum information. However, while doing so, I started a whirlwind tour of deep questions in physics which become unavoidable as you think harder and deeper about quantum teleportation. I’ve only just begun this journey, but using quantum teleportation as a springboard has already led me to contemplate crazy things such as time-travel via coupling postselection with quantum teleportation and the subtleties of entanglement. In other words, quantum teleportation may not be the instantaneous Stargate style teleportation you had in mind, but it’s incredibly powerful in its own right. Personally, I think we’ve barely begun to understand the full extent of its ramifications.
Also, loosely following technology that could be used to build a real working time machine. Anyone with an interest in time travel is welcome to participate.
But, I have been watching tech news for what could be used to build a time machine. I think we are pretty close. You’d still need a few physics guys with 150+ IQ’s to work on the equations, a guy with a 200+ IQ to figure out how to put the whole thing together, and a guy with billions of dollars to fund it. But most of this stuff is for sale to the public, (short list):
