Time Portal

Even as Gene stood with his back toward the chalkboard, sweat beading on his forehead, the blue disc hovered silently if not defiantly.

It was baffling. Nothing was reappearing on the other side.

Where did everything go? They’d tossed in a pencil, alarm clock (with the alarm sounding), a handball, a basketball… All had vanished.

The calculations seemed simple enough. A 60-second time portal. Things were disappearing when you threw them in but weren’t emerging from the other side a minute later as they should. Calculations were recalculated and double checked. Everything was as it should be. What was happening here?

So now Gene rested his hand on a powerful transmitter sitting on a cart with wheels. He planned to push the cart through the portal and have them search for the signal that emitted from it 60 seconds in the future.

So the cart was wheeled forward and pushed into the portal where upon it abruptly vanished from sight.

The technicians placed on their headsets and adjusted the dials on their radios while a 60-second timer was initiated. Find the signal 60 seconds from now and they would know where things were going and why things weren’t reappearing on the other side.

What they discovered was truly astonishing, but in retrospect completely logical.

Yes, the signal was detected. Very faint and very distant but completely detectable. So where did the transmitter go?

The transmitter was in space, apparently orbiting the sun, thousands of miles away from Earth.

In the sixty seconds that the transmitter traveled into the future, Earth itself had moved away by thousands of miles.

At the equator, the rotation of Earth is about 1,037 mph (1,670 km/h), or over 17 miles a minute. Meanwhile, Earth has an orbital speed around the sun of about 67,000 mph (107,000 km/h), or about 1,100 miles per minute. The sun and the solar system orbit the center of the Milky Way Galaxy at approximately 448,000 mph (720,000 km/h) or 7,466 miles per minute.

So when the transmitter was pushed into the time portal and jumped 60 seconds into the future, the Earth spun around it’s axis 17 miles at the equator, 1,100 miles around the sun and 7,466 miles around the galactic center. Simply put, the transmitter came out sixty seconds later exactly where it went in, but Earth itself was no longer in that location.

Therefore the pencil, the ringing alarm clock, the handball, basketball and the transmitter all emerged into space, orbiting the sun over 8,000 miles behind Earth’s orbit.

It turns out the time portal was the easiest and most efficient way to send things into space.

Is Time Travel Even Real?

Although I wrote a time travel novel once (Time Gods), time travel has many problems that most sci-fi authors don’t take into consideration.

For example, consider that Earth spins at the equator at about a thousand miles per hour and the Earth orbits around the sun an average speed of 29.8km/s or 65,000 mph (105,000 kph).

The sun also orbits the galactic center at about 225 km per second (140 miles per second) or about 486,000 miles per hour.

The Milky Way galaxy is moving toward the Andromeda Galaxy at about 2.1 million kilometers per hour, or 1.305 million miles per hour.

Now, get in a time machine and go forward (or backwards) an hour or so. Will you find yourself in the same place on Earth only in a different time, or will you find yourself floating in space, Earth having moved hundreds of thousands of miles away in the short period of your time travel?

Now wouldn’t that make an interesting idea for a time travel novel!

Aside from that, and disregarding the impracticality of string theory, time travel in reverse isn’t possible, but time travel to the future certainly is possible under special circumstances.

Consider that you have an identical twin and both of you are in a space ship orbiting a black hole. On your birthday, your twin sibling decides he wants to get in a shuttle craft and take a closer look at the event horizon of the black hole. So he gets inside the craft and travels near the event horizon and then comes back 20 minutes later, only to find you are a very old person and that you have aged many, many years. What you see, as your twin gets closer to the event horizon, is that he slows down until he is practically motionless. Years go by and you grow old. Your twin, down there in that shuttle, still seems frozen in time, then eventually he slowly rises up to the space craft and comes back inside. Although you are now old, you are looking at a young twin!

Another example was introduced by Albert Einstein. Consider two twins, named Biff and Cliff. On their 20th birthday, Biff decides to get in a spaceship and take off into outer space, traveling at nearly the speed of light.

He journeys around the cosmos at this speed for about 5 years, returning to the Earth when he is 25 years old.

Cliff, on the other hand, remains on the Earth. When Biff returns, it turns out that Cliff is 95 years old.

So yes, under certain conditions forward time travel is possible, but not reverse time travel, and certainly if you had a “time machine” then Earth might move away from under you while you are going 30 minutes forward or backward.

Why doesn't anyone else besides me believe in time traveling?

I don’t know the answer to your question. However, consider this. We are not standing still. In time the Earth rotates around it’s axis, the Earth also rotates around the sun, the sun rotates around the galactic center and the galaxy is merging with Andromeda.
We are therefore moving at hundreds of thousands of miles per hour in space. Fast forward 10 seconds and you will find yourself in outer-space without a spacesuit!
