# Einstein would be proud

Really amazing, is what most people say I am,
Of ways to move, I'm the fastest way out of a jam.

Some people think I'm a hole, but not quite,
Expect me to be 4D, you'd be right.

Now be like an ant or a line, my twist awaits,
Sometimes orange or sometimes blue, are my gates.

What am I?

You are:

A Portal

Really amazing, is what most people say I am,

Portals are amazing

Of ways to move, I'm the fastest way out of a jam.

Portals are definitely a quick way to get from place to place

Some people think I'm a hole, but not quite,

Portals may seem like holes, but they're not

Expect me to be 4D, you'd be right.

It is hypothesized that tessarects are the key to opening portals

Now be like an ant or a line, my twist awaits,

A portal/wormhole is the shortest distance between two points in spacetime, as is a line. Additionally, ants optimize their routes to get around quickly

Sometimes orange or sometimes blue, are my gates.

In the game Portal, the two colors of portals are orange and blue

As for the title:

A wormhole would be a "non-trivial solution of the Einstein field equations," which I'm sure he'd be proud. Additionally, thanks to @M.Herzkamp, taking the first letter of each line gives ROSENS, referring to the Einstein-Rosen Bridge, showing that two black holes can be connected by a wormhole, or portal

• That is correct, however, your ant and line one is off. Hint: Think of a piece of paper example. – Joe-You-Know Jul 17 '18 at 15:28
• Also, there is a secret hint I'd like for people to find. – Joe-You-Know Jul 17 '18 at 15:33
• Concerning the first letter of each line, the Einstein-Rosen bridge comes to mind. Maybe he means "Rosen's bridge"? – M.Herzkamp Jul 17 '18 at 16:18
• The ant line refers to the analogy of an Ant walking on a strip of paper he is confined to 2d, but the ant can walk in 3d around a string. This is the analogy of how a portal could work. – wolfram42 Jul 17 '18 at 19:15
• @wolfram42 not that tough Experiment where the ant could go across a entire Paper with one by folding it side? (Folding of Space/Wormholes) – Serverfrog Jul 18 '18 at 9:13

Are you a

Black hole

Really amazing, is what most people say I am,
Of ways to move, I'm the fastest way out of a jam.

They can pull things into them selves with their strong gravitational pull.

Some people think I'm a hole, but not quite,
Expect me to be 4D, you'd be right.

They are not a hole but a round clump of dark matter.

Now be like an ant or a line, my twist awaits,
Sometimes orange or sometimes blue, are my gates.

This might refer to the light that doesn't come out of it. Also the ant trail may refer to the fact they scientists can trace a trail of neutrinos from large intergalactic power sources.

Also the title

Einstein researched black holes.

• Excellent answer, but not quite the answer I'm looking for. – Joe-You-Know Jul 17 '18 at 15:27

Could you be

Gravity?

Really amazing, is what most people say I am,

Gravity really is amazing — without it, you would never have learnt how to walk.

Of ways to move, I'm the fastest way out of a jam.

A reference to the TV show, Gravity Falls, in the seventh episode of the first season, Double Dipper. Basically, the main character (Dipper Pines) wants to impress a girl that he likes (Wendy Corduroy) and, in particular, wants to ask her to dance. His plan: make some clones of himself.

Unfortunately, his plan goes horribly wrong and is ruined by a clone referred to as Paper Jam Dipper who was made by accident. Then, all the clones turn on Dipper — but in the end, all the clones make contact with water due to gravity (the water falls on them) and are all defeated.

Some people think I'm a hole, but not quite,

Gravity is distorted space-time;${}^1$ when an object has mass, it bends space (changes its shape and "weaves out its fabric") and stretches it out, thus making gravity. You might as well call it a hole... but not quite (as it is more like a curve).
${}^1$More about distortions in particular can be found here.

Expect me to be 4D, you'd be right.

Gravity used to be considered the fourth dimension for several years (the theory being first proposed in May, $2006$).
The only flaw is, it has been proven not to be (here and here), so it is not right to say it is.

Now be like an ant or a line, my twist awaits,

Gravity has so much power, we are like ants compared to it; its power is pulling and twisting space-time, acting as a very strong force (for us, at least); and it always awaits when we jump.

Sometimes orange or sometimes blue, are my gates.

Photons${}^1$ (a quantum particle that makes up light) orbit a black hole (creating what is known as the photon sphere), which is surrounded by gravity. Light is composed of all kinds of colours, including orange and blue.
${}^1$Go here or here.

...of the riddle — the answer might be gravity, which is something that Einstein (and his theories and equations) are heavily related to.

You are:

Light

Really amazing, is what most people say I am, Of ways to move, I'm the fastest way out of a jam.

Nothing is faster than the speed of light

Some people think I'm a hole, but not quite, Expect me to be 4D, you'd be right.

the 4D light field is defined as radiance along rays in empty space

Now be like an ant or a line, my twist awaits, Sometimes orange or sometimes blue, are my gates.

Light can be orange or blue, and it can be treated like a wave or a particle

Title:

Einstein's most widely known work, E = mc^2, involves the speed of light, c.

• Nice answer, but not quite what I'm looking for. – Joe-You-Know Jul 17 '18 at 15:34
