Hot Wheels you mean, but I agree, putting hot sauce on them won't make them edible
Life is merely the existential essence of being. It is only a transitory phase of a collection of plasmatic materials encountered by carbon-based beings who have the temerity to believe they are existing.
Very true! More space exploration, now!Time to head out of the mansion and start investigating....
@z78sabjan, the fact that "there are hundreds of theories out there" does not mean that "we don't have the slightest clue". Based on what we know, some things are virtually certain, some things are likely, some things are possible, and some things are impossible. It's considered very likely, virtually certain, that the universe has a set mass and energy. It's considered likely, but far from certain, that the universe will continue to expand.
The attraction of some of the unlikely, but possible, hypotheses, is that they can offer explanations that we have no other hypotheses, much less theories, for. That is, however, provided that they can be fleshed out. Some of these hypotheses have the potential to turn things on their head, and upset existing theories. However, they all have a much higher probability of failing. Even in success, the "upset" is likely to be more aptly described in common parlance as "a minor adjustment". Which, of course, is more than enough to upset a theoretical physicist.
Those small probabilities of minor adjustments must not be allowed to obfuscate the scientific knowledge that we do have. Evolution is real, even if there has been and will be adjustments to the theory. Human caused climate change is real, even if climate science is still in its beginning. Unlike so many other people, organizations, and movements, the scientific community has the integrity to admit that it's absolutely impossible to be absolutely certain, which leaves a very theoretical, infinitesimally small possibility that it's completely wrong. It's still more certain than any other known method of comprehending the world, and that tiny possibility is getting far more attention than it deserves, these days.
Until we have identified black matter and black energy, the uncertainty is significant on the issue of expansion / contraction / equilibrium / other, but we do "have a clue". On the infinity of the universe, we have much more than a clue: It is, almost certainly, not infinite.
