I guess if you were some kind of 7 dimensional being and had the technology to rewind a universe.

lol no.

The challenge for us now is we may not have the breakthrough that leads to the invention that leads to new way of thinking that allows time travel.

Imagine explaining nuclear fusion to a mind that hasn't experienced steam or fossil fuels. My point is on "ever possible" it is too early to say as I am of the mind that humanity still has long ways to go technologically.

If I were to speculate I'd say the following.

1. Traveling forward seems most likely due to relativity of a person or object in a device and those outside. Think of it like stasis.

2. Fixed points creating a loop so time travel would be possible at a certain point far in the future.

3. Time Lord travel in a Tardis going where ever you want...this sadly seems very unlikely and as others have touched on could destroy reality.

Yes, it is possible. but only in one direction and at fixed "speed".

Simple. We haven't seen time travellers because we haven't invented it yet.

In order to travel back in time, you need to have a receiver...after all, you cannot create something from nothing. No time travelers can travel to a period before the receiver is invented.

It makes no difference though. Soon we will all live in a digital world, where time travel is easily performed. Time travelers will be the hackers of the future.

88 miles per hour?

You know your nerd-stuff.

Sadly, I assume many of the younger posters here have no idea what you're talking about.

I can confirm that time travel is possible.

Ever heard of time dilation? If not, review it.

This matter concerns Einstein's Theory of General Relativity. One can move forward through time more slowly relative to another region of spacetime.

Examples are the astronauts who frequent the international space station. These astronauts are a few billionths of a second younger relative to people on Earth because of the gravitational potential differences.

Earth's Surface gravitational potential is 60 MJ/kg.

LEO (Low Earth Orbit) gravitational potential is 57 MJ/kg.

The lower the gravitational potential, the slower time passes.

I never actualky got around to watching the first.  My parents did rent the second when I was young (Maybe 5 or 6.)  I do remember watching bits and pieces of it when I was younger.  Though I did use to watch the cartoon.

it's not possible in the sense that you can travel back and forth in it no


when you can do that then you can confirm it not before
