Sorry couldn't resist, love this subject.

Time travel into the future relative to something / someone else is possible.

Einsteins theory of relativity states that the speed of light never changes relative to anything, therefore (this has been proven), the passage of time differs for objects travelling at different speeds relative to each other.

if you travel at half the speed of light relative to something else, you will experience time at half the speed of that something. 90% the speed of light and time will be 1/10 of the 'something'.

This means if you travelled at half the speed of light (150,000 Km/s) relative to earth for 20 years and returned to earth, all your friends have aged 40years and you are only 20 years older. You have just time travelled 20 years into the future relative to anything on earth.

Real life time travel
1. Astronauts in orbit travel at high speed, not really anything compared to the speed of light but, they will have timetravelled by a significant fraction of a second when they come back down.
2. GPS satelite clocks have to match the clocks on earth exactly to work. they have to be adjusted by a predictable fraction of a second at a set interval to maintain this.
3. Particles that are created in particle accelerators, often last millions of billionths of a second before disintegrating. Increasing the speed of collision from say 99% the speed of light to 99.9% the speed of light will make those particles last 10 times as long before disintegrating.

So you can't (as far as we know) jump in to the future, but we can slow time down for us compared to something else and travel forward in time much slower than said something, there fore travelling forward in time relative to it.

No, passage of time doesn't differ. How matter behaves in regards to increase of mass due to higher velocities is what's happening. There is no dimension of temporal travel, no arrow of time nor doesn't current physics forbid objects from freely at a whim to move backwards in time. We don't see this happening however, and it's a puzzle as to why. Simple answer, time doesn't exist.

Marking arbitrary positions of the sun across the sky and placing numbers upon a disc on a wall with hands that point to a particular number to denote the suns position in the sky is not a measure of time. You have to be a literal retard to buy into that crap.
