Do you believe in time travel

[DiaperboyEddie12]

Just wondering about your thoughts on this.  Do you believe in time travel?

[square_duck]

Sorry to be a downer for any believers, but the construct or concept of "time" is a man made idea, not a natural thing. If it does'nt exist, it cannot be traveled in, or used really much for anything other than planting/harvesting crops...... Or explaining to your boss why you are late to work...?

i beg God for it.

The fact there's never been a documented time traveller means time travel will always be impossible.

How ever fast we drive, "Time" is overtaking us at the speed of light.

If we could catch up with the speed of light, time would stand still.

As nothing can travel faster than the speed of light, we can't travel into the future.

Probably not possible though

that is because the faster one goes the more mass one gets, it acts as a brake, but that assumes that speed is the only means of obtaining time travel, there are others, if God chooses to he can send someone forward or backwards, there might be temporal wormholes, any number of things.

Stephen Hawkins also used this premise to attempt to prove that time travel [is/was/will be] impossible, but this is based on the concept that time is a constant, which physics has proven incorrect. Everything that we know about physics is based on time being a constant which determines that travelling through time, a constant, is not possible. However, if we presume that time is not a constant, it must be possible to travel through time.

Looking into the results of time travel can easily create a time-paradox, where the time-traveller alters the history of themselves thus disabling the travellers ability to time-travel in the first place. Since paradoxes with time could easily be created, travelling in time itself is a problem best avoided. As a result, even if at a time in the future that time travel is available, only the foolish would risk same. As a result, the premise that we, in this century are not generally aware or, there has been no documented time traveller, does not conclusively mean that time travel will always be impossible... all it does mean is that time travel [will/is/has] not be[en] available without deep analysis of all the impacts to past/present and future events - and a party and/or newspaper article is of no real benefit to this world.

There is a general perception that nothing can travel faster that the speed of light. (186,00 miles/second OR 300,000 km/sec).

A few people quote Einstein's theory E=MC2 (energy = mass times the speed of light squared) to attempt to prove that one cannot pass the speed of light. However, the E=MC2 calculation is based on a number of presumptions - one key one is that light does not have mass/weight. This in itself is incorrect - as light uses photons, and photons do have a weight. As a result, the equation itself fails, and so does the theory that the speed of light is a maximum and/or a constant.

Before the creation of a jet engine (1939), the maximum speed was from steam / piston based engines was close to 500 mph (700 km/h), where the speed of sound (known as Mach 1) was supposed to be the maximum. Jet engines pushed the speed to [1967 4,519 mph (7,274 km/h)] with rockets hitting speeds of [1981 17,500mph (28,000 km/h)]. Considering that rockets use multistage power, i.e. stage 1 accelerates from 0 to 100, stage 2 goes from 100 to 500 and so forth, it is, in theory, possible, with enough stages, to pass the speed of light.

When we exceed this speed, under current thinking, time is still passing by, so we are not travelling against time, which would be the correct description of time travel - travelling backwards in time to an earlier date / time and/or travelling forward in time to a later date/time. We ARE travelling forward in time to a later date/time, however, the time it takes us to reach a later date/time is exactly the difference between now and the later date/time.

Depends upon how you define time travel. Astronauts time travel every time they go into space. A few have spent enough time in space for them to have time traveled a measurable amount.

Backwards time travel no. Forwards time travel kinda. With a black hole the closer you get the more time seems to slow down, this is true for pretty much anything with the denser the object the greater the effect. But keeping that in mind if you went near a blackhole (pretend you can survive it and get back), at a point the closer you get to it a day to you might be a year on earth. So in that way you kinda travel a year into the future. not a scientist so it could be a bit wrong?
