Oh dear. I travel through time and space everyday. Something odd must be going on because I somehow manage to be late for everything...

However, physicist Albert Einstein’s theory of special relativity suggests that time passes at different rates for different people.

True that. Time seemed to stand still in 2004 when I'd hear a speech by John Kerry, who served in Vietnam.

I thought the “Big Bangers” threw in the towel at this point.

Only with a DeLorean, a flux capacitor, and some plutonium. 1.21 Gigawatts!

Hello, curious kids! Do you have a question you’d like an expert to answer? Ask an adult to send your question to CuriousKidsUS@theconversation.com.

Ya gotta love people who self describe themselves as, "Experts" when they really have no clue whatsoever in regards to the fundamental basic questions involving cosmology/life.

I am actually teaching a course on time travel. If you’d like to attend, be here last Thursday at 8pm.

The past happened, the future hasn’t - we’re in the present.

Time is relative, dependent,
You can save it, you can spend it
Doing things you like to do
Or learning how
You can’t see it, you can’t taste it
But you certainly can waste it
Which is really what we’re doing here right now!

If UFOs are not military hardware or natural phenomena, I think time traveling humans (our distant descendants) are far more likely than aliens.

“One of the major problems encountered in time travel is not that of becoming your own father or mother. There is no problem in becoming your own father or mother that a broad-minded and well-adjusted family can’t cope with. There is no problem with changing the course of history—the course of history does not change because it all fits together like a jigsaw. All the important changes have happened before the things they were supposed to change and it all sorts itself out in the end.

The major problem is simply one of grammar, and the main work to consult in this matter is Dr. Dan Streetmentioner’s Time Traveler’s Handbook of 1001 Tense Formations. It will tell you, for instance, how to describe something that was about to happen to you in the past before you avoided it by time-jumping forward two days in order to avoid it. The event will be described differently according to whether you are talking about it from the standpoint of your own natural time, from a time in the further future, or a time in the further past and is further complicated by the possibility of conducting conversations while you are actually traveling from one time to another with the intention of becoming your own mother or father.

Most readers get as far as the Future Semiconditionally Modified Subinverted Plagal Past Subjunctive Intentional before giving up; and in fact in later editions of the book all pages beyond this point have been left blank to save on printing costs.

The Hitchhiker’s Guide to the Galaxy skips lightly over this tangle of academic abstraction, pausing only to note that the term “Future Perfect” has been abandoned since it was discovered not to be.”
― Douglas Adams, The Restaurant at the End of the Universe

Everything in the universe is moving.

The moon circles the earth, the earth circles the sun, and the sun is moving within our galaxy and our galaxy is moving within the universe.

The reason time travel is impossible is that we are never in one spot with in the universe, we are in constant motion.

A plumber repairing somebody’s toilet is ten times more valuable to the society than experts discussing time travel and related “scientific” garbage.

To the future possibly, but not the past.
