Unsure why even bother with wheels if you are going to magnetically levitate the bike.

 

Sounds like the Mag levitating trains that already ride on a magnetic field.

 

Two types of mag lev trains exist. A kind that rides on a cushion of the same polarity (push), and one that is lifted upwards by opposite polarities (pull).

 

By adjusting magnetic angles they can arrive at incredible speeds.

Because for civilian vehicles magnetic levitation would need a corresponding field generated by a maglev road, but not if the wheels were magnetically suspended around the axles. This would reduce the problem of axel damage by hazards, a smoother ride, and faster acceleration.

if your magnetic bearings are strong enough to suspend the wheel around the axle, then yes to a degree.

however, the biggest speed killer for a bike is the drag coefficient.

the question is whether or not you can keep down your rotational mass.

How would they keep down the rotational mass?

What could be done to eliminate the drag coefficient?

I recently saw Big Hero 6 in theatres.

One of the main heroes, Go Go Tomago, is working on a faster bicycle by using wheels suspended electromagnetically.

Would such technology work in real life? I've seen it done before, but only in works of fiction.

Venus has probably been a 'wasteland' since shortly after it formed.

It's not like it was ever earthlike, and runaway greenhouse effects altered it, to the way it is today.

 

Oh, and dinosaurs did not all become extinct. Some did survive and continued to evolve in the new environment.

You may have had one for supper. You do like chicken don't you ?

I already knew about the link between birds and the raptor family of dinosaurs.

Well how long is it estimated that Venus became a wasteland anyway?

In a fictional setting the chances are exactly as the author wants them to be.

Yes, but I still wish to know how it could work in real life with real sciences applied.

Exactly, so what are the chances of them surviving more Earth-like conditions?

They already evolved to become the microbes they were. What's there to stop the surviving ones to continue that trend?

Changing conditions is what killed the dinosaurs, isn't it? When the meteor hit most life on Earth was destroyed, excluding those who hid well enough from what was thrown into the atmosphere.

This kind of relates to a discussion I started once about the terraforming of other planets.

I don't remember if we covered this part.

Here's the scenario I was wondering about;

-Something came crashing into Venus.

-Said object was big, heavy and fast enough to knock away the harsher parts of the atmosphere.

-The planet is now on a different axis that causes it to rotate the same way as Earth.

-Before the whole incident there were already primitive microorganisms on the surface.

Under the new, Earth-like conditions that have befallen Venus in this scenario, what would happen to said microbes? Would they start to evolve, or would they stay unchanged?

Well, with that in mind, would it make sense for a sentient being or other creature to one day evolve into a form that can be accessed in the same dimensions as us?

 

As ajb mentions, it doesn't help to look at it as "our dimension/their dimension". We live in three spatial dimensions and one temporal dimension.

What if they, or we, could find a way to be sensed in this temporal dimension?

 

As ajb points out, a dimension gives perspective, it's not a place you can go visit.

 

Have you ever visited Flatland? It has only length and width as spatial dimensions, plus time. You can draw it on a piece of paper, as long as you agree that your pen adds no height to Flatland. All the beings in Flatland have no height, can't even conceive of what it is because nothing has height in Flatland, they have no senses that can detect height because they don't need them.

 

When YOU visit Flatland, you still have height, but everyone from Flatland only sees the parts of you that have length and width, that come into contact with their flat world. You appear just like they do. You'd have some superpowers, like being able to change size as you move through a dimension the Flatlanders don't have access to. You could make yourself disappear briefly by jumping, something no Flatlander can do.

 

So there's an example of how you could visit another planet (making you an alien), and have access to a dimension the inhabitants can't sense. You could exist there and parts of you could be in another dimension.

What if these aliens had access to a technology that allowed them to be sensed in our dimension, or technology that allowed us to sense in their dimension?

That is not how you should think of dimensions.

 

We live in 3+1 dimensions. Say you have a party in your room and you would like to invite me. What would I need to know? Well I need to know where your house is, that is specified by two numbers, the longitude and latitude of your house. I then also need to know it is up stairs, so you need to tell me it is on the first floor. So we have three numbers (x,y,z). The fourth number I need is the time of your party; you could use the Julian calendar to specify that. So I need (x,y,z,t).

 

 

More or other dimensions would be something similar. Other 'directions' that need specifying.

Okay, then let me change it to "separate plane of existence" if that works better.

I think the definition of alien is straightforward, but you may want to define what you mean by dimension,

A different dimension of being seen, heard, touched, tasted or smelled. That's what they mean by the second dimension and third dimension, right?

So basically your question is, "what is the definition of 'alien?'"

Well, yes, kind of. Alien means outside of where we live, foreign, or of extraterrestrial origin.

Look at Pacific Rim. The alien civilization who sent the Kaiju still count since they're not from Earth. Same with Krang from Teenage Mutant Ninja Turtles (and the aliens of the same name in the 2012 reboot).

If a race of people were from another dimension, but in that dimension they were from another planet, would they still be aliens?

What would happen if the microbes in the Venusian clouds fell to the planet's surface?

Would they be destroyed, or would something different happen to them?

Yes- but isn't that dangerous? The big Venusian microbial clouds could leave their home planet, and expand into space. They might come to Earth and invade us. They'd have rich pickings here - 7,000,000,000 warm human bodies to infest and replicate in. Before you know it, we'd all be taken over, and just be zombie hosts for Venusian microbes. Dare we take such a risk?

 

Maybe we should send a 1,000 megaton nuclear-armed space-probe to Venus. To nuke the planet from orbit. It's the only way to be sure.

That's terrible. We can't just nuke somewhere out of the paranoid theory of it attacking us. What example of the human race would that send to other civilizations? Bad! They'd think of us as mere monsters.

How about I say something like humanity did something that made Venus habitable, but at the same time caused the microbes to fall to the planet and mutate into sentient beings?

Or maybe they had been evolving into such creatures for a long time, and by decades into the future we can finally confirm their existance?

If they're sentient and intelligent microbes, why not?

Or how about this? What if mankind did something to Venus that mutated the microbes in the clouds into bigger life forms?

So they'd likely be just too small for us to see?

What if I said they had evolved into the beings I described earlier who were resistant to such extreme heat and could breathe the CO2 on Venus?

I was thinking that if that were the case, they didn't first encounter other races in the galaxy until Earth figured out how to terraform Venus.

But how fast did Venus' runaway greenhouse effect give in on the planet?

Evolution takes centuries last I heard, so are you sure they could've evolved fast enough to gain those immunities?

Hi, me again, with another problem involving my story concept from before.

One of the alien races in the story is situated on Venus, which of course would not be a suitable place for life as we know today.

I was thinking what if the Venusians were underground dwelling beings who could survive extreme heat (up to 1000 degrees Celsius), and breathed carbon dioxide. They would also need something that would grant them immunity to sulphuric acid rain.

But what would they have to be made of to survive the conditions on that planet?

I could make them closed cockpit, but then nobody would notice they're supposed to be hoverbikes.

Look at this. Without wheels, would this still look motorcycle-esque to you?:

Couldn't I just keep the open-cockpit design and say an electromagnetic field moves air and debris around the rider?
